Another way to approach this is by directly monitoring those inputs. This can be done in the Delta Control Panels Patchbay/Router page by selecting the Delta input and connecting it directly to the Delta output. You can also use the Delta panels Monitor Mixer to send the signal at the inputs to the Delta outputs, as well as mix those signals with the software outputs, i.e., your music software sending audio to the Delta outputs. This, and other recording/monitoring scenarios are covered in the Tutorials section toward the end of the manual.

Delta Control Panel Installation on the Mac
The Delta Control Panel may be placed anywhere on your hard drive, or any partition of your hard drive that you find convenient. Once the control panel file has been dragged from the CD onto your hard drive, you may double click it to launch the Delta Control Panel software. You may also create an alias to the control panel by highlighting it, then holding Apple key+M. This alias can then be placed on your desktop. NOTE: When using a music software program that is ASIO capable, launch the Delta Control Panel software from within that program. Some of the control panel functions will be controlled from within that program, such as master clock setting and sample rate, so it is desirable to launch the music program first, and then the Delta Control Panel from the the programs launch or control panel button. Without the music program open however, it is okay to open the Delta panel from your desktop or other location.

Delta 1010LT Control Panel Software - PC
Once the Delta 1010LT is properly installed, an "M Audio Delta H/W" icon will be displayed in your Windows Control Panel. By double-clicking on that icon, you will launch the Delta Control Panel software. You may also launch the Delta Control Panel software from the desktop if you have previously created a shortcut there (see "Verifying Delta Control Panel Software Installation" section for instructions on how to do this). Once the Delta Control Panel software has been opened, you will see the main panel and its several tabs. To display a desired page, click on its tab. Below are functional descriptions of each page. NOTE: When using a music software program that is ASIO capable, launch the Delta Control Panel software from within that program. There will be a button in the ASIO or Audio setup page that will allow you to do so. Some of the control panel functions will be controlled from within that program, such as master clock setting and sample rate, so it is desirable to launch the music program first, and then the Delta Control Panel from the the programs launch or control panel button. Without the music program open however, it is okay to open the Delta panel from your desktop or other location.

Monitor Mixer Page

The Monitor Mixer is the first page that appears when the Delta Control Panel is opened, and controls the digital mixer built into the Delta 1010LTs PCI controller chip. As described in previous sections, the output of this mixer may be assigned to the OUT1/OUT2 analog outputs and/or the S/PDIF Out digital output (this selection is made in the Patchbay Router page). At the same time, the mixer outputs may be recorded in stereo by software.
The Monitor Mixer Page is essentially a collection of volume level faders, audio level (or peak) meters, and solo/mute controls. For each mixer output and input channel there is one of each: a volume fader, a peak meter, a solo control, and a mute control. LEVEL FADERS: Each volume fader may be controlled by dragging the fader handle vertically with the mouse, or by clicking on the handle to make it active and then adjusting it with the up/down cursor keys of your computer keyboard. Because the mixer has no gain, these faders only attenuate (reduce) the signal levels. The highest setting is 0dB, or Unity Gain. The default fader setting is the quietest setting, 144dB, which essentially mutes the audio. A pair of level faders may be "ganged" so that both channels may be adjusted together as a stereo pair. Also, at the top of each fader and meter is a fader level "fine adjustment" control. Clicking on the small "up" and "down" arrows will adjust the corresponding fader setting in 0.5dB increments. Next to each fine adjustment control is a numerical fader readout that is always current and active. PEAK METERS: Each peak meter indicates an audio signal level in "dB relative to full-scale." This means that a full-scale signal is referred to as "0 dB" and a signal that is 12dB "quieter" than full-scale is referred to as "-12dB." The meters are vertically color-coded into three sections: green, yellow and red. The green section represents a safe zone, ranging from approximately -48dB to -12dB. Most audio signals should appropriately fill this section of the meter. The yellow section ranges from -12dB to -3dB as the signal approaches a hotter level. For best capture resolution, recording in this area is both safe and advised. The red section of the meter ranges from -3dB to 0dB. On the input level meters, a 0dB condition indicates overload and audio clipping may occur. Therefore be careful to adjust the incoming audio levels so that they do not peak in the red section too long (you might use the monitoring capability of the Delta 1010LT to let your ears be the judge). On all output level meters, 0dB indicates full-scale output. Unlike the inputs, clipping is impossible on the outputs because of the 36-bit resolution built into the mixer hardware.

Patchbay/Router Page

The Patchbay/Router page allows you to connect each of the Delta 1010LTs hardware outputs (4 pairs of analog outputs and 1 pair of digital output channels) to specific audio sources within the Delta 1010LT board. To display this page, click the "Patchbay/Router" tab of the Delta Control Panel. The leftmost vertical column of Patchbay/Router page, "H/W Out 1/2," connects this analog stereo pair to one of eight stereo sources: 1. The default setting, "WavOut 1/2," connects ports OUT1 and OUT2 to your music software or Windows multimedia applet. In other words, when music software plays audio to the device named "WavOut 1/2 Delta-1010LT" it will be routed directly to the "hardware" analog outputs 1 & 2 of your 1010LT breakout cable. 2. The second option, "Monitor Mixer," connects ports OUT1 and OUT2 to the outputs of the Delta 1010LT monitor mixer. For more information of the capabilities of the monitor mixer, please see the section "Monitor Mixer Page." 3. The third option, "S/PDIF In," connects ports OUT1 and OUT2 directly to the hardware S/PDIF input on the Delta 1010LT PCI host card. The left channel of the S/PDIF In is routed to OUT1 and the right channel of the S/PDIF In is routed to OUT2. 4. The fourth option, "S/PDIF In (L/R Rev.)," functions identically to the third option, except that the left and right channels are swapped. Therefore in this mode, the left channel of the S/PDIF In is routed to OUT2 and the right channel of the S/PDIF In is routed to OUT1. 5. Selections five through eight connect the hardware analog inputs 1 & 2, 3 & 4, 5 & 6, or 7 & 8 (respectively) directly to the 1010LTs hardware analog outputs 1 & 2. For example, if "H/W In 1/2" were selected, any signal present at the IN1 port will be copied to OUT1, and any signal present at the IN2 port will be copied to OUT2. This same behavior applies to "H/W In 3/4," "H/W In 5/6," and "H/W In 7/8" when selected. The next three vertical columns of the Patchbay/Router page (from left to right), "H/W Out 3/4," "H/W Out 5/6," and "H/W Out 7/8," connect these hardware analog outputs to one of four sources. Since the three columns function identically, well use "H/W Out 3/4" as the example: 1. The default setting, "WavOut 3/4," connects ports OUT3 and OUT4 to your music software or Windows multimedia applet. In other words, when music software plays audio to the device named "WavOut 3/4 Delta-1010LT" it will be routed directly to the "hardware" analog outputs 3 & 4 of your 1010LT breakout cable. 2. The second option, "S/PDIF In," connects ports OUT3 and OUT4 directly to the hardware S/PDIF input on the Delta 1010LT PCI host card. The left channel of the S/PDIF In is routed to OUT3 and the right channel of the S/PDIF In is routed to OUT4. 3. The third option, "S/PDIF In (L/R Rev.)," functions identically to the second option, except that the left and right channels are swapped. Therefore in this

S/PDIF Page

The S/PDIF page of the Delta Control Panel configures the S/PDIF output format and displays the status of the S/PDIF input. To display this page, click the "S/PDIF" tab of the Delta Control Panel software. DIGITAL INPUT: This group box displays the current S/PDIF input status. The Delta 1010LTs S/PDIF receiver is capable of recognizing a valid input signal versus an invalid, corrupt or non-present one. When a valid signal is detected at S/PDIF In, this group box displays "Valid Input Detected." When an invalid signal is detected or no signal is present, the group box displays "Invalid or Not Present." Below this message are two grayed-out buttons: "Coax(RCA)" and "Optical." These are functions of the Delta DiO 2496, another product in the M-Audio Delta line, one with both optical and coaxial S/PDIF inputs. These controls do not apply to the Delta 1010LT. DIGITALOUTPUT FORMAT: Within the "Digital Output Format" group, you choose the digital audio format of the S/PDIF output. The default setting, "Consumer," is a true S/PDIF format and is recognized by all consumer devices. The alternate "Professional" setting is an AES/EBU type data stream, but electrically S/PDIF. This is a work-around that is recognized by some but not all AES/EBU devices. For both consumer and professional output formats, the "Advanced" checkbox will allow you to force a few particular status bits in the outgoing S/PDIF signal. The advanced option is for expert users only; however, if you decide to go exploring, change a few bit settings and get lost, you can always select the "Restore Defaults" button to restore the outgoing status bits to their factory settings. When "Consumer" and "Advanced" are both selected, the group "Consumer Format Advanced Settings" will appear. When "Professional" and "Advanced" are both selected, the group "Professional Format Advanced Settings" will appear. These groups are described below: CONSUMER FORMAT ADVANCED SETTINGS (Copy Mode): Copy protection, also known as Serial Copy Management System (SCMS), is written into the S/PDIF subcode, a reserved part of the S/PDIF digital stream that is independent of the actual audio data being transmitted. It can be used to inhibit the amount of copies that can be made, or allow for unlimited copying. Three SCMS modes are available. "Original (Copy Permitted)" indicates that the source material may be copied by a receiving device. "1st Generation" indicates that the source material is a first generation copy. Most devices that are capable of recording will reject material with this SCMS mode set. The final option is "No SCMS" which may be used to override the other two modes and allow a recording device to successfully record the audio

Delta 1010LT Control Panel Software - Mac
The Delta Control Panel must be placed on the hard drive by dragging the application from the Drivers CD. Once this is done, an alias may be created by highlighting the Delta Control Panel on the hard drive and pressing the Apple key+M. Then, this alias may be dragged to the desktop. Double clicking either will launch the control panel. Once the Delta Control Panel software has been opened, you will see the main panel and its several tabs. To display a desired page, click on its tab. Below are functional descriptions of each page. NOTE: When using a music software program that is ASIO capable, launch the Delta Control Panel software from within that program. There will be a button in the ASIO or Audio setup page that will allow you to do so. Some of the control panel functions will be controlled from within that program, such as master clock setting and sample rate, so it is desirable to launch the music program first, and then the Delta Control Panel from the the programs launch or control panel button. Without the music program open however, it is okay to open the Delta panel from your desktop or other location.
The Monitor Mixer Page is essentially a collection of volume level faders, audio level (or peak) meters, and solo/mute controls. For each mixer output and input channel there is one of each: a volume fader, a peak meter, a solo control, and a mute control.
LEVEL FADERS: Each volume fader may be controlled by dragging the fader handle vertically with the mouse, or by clicking on the handle to make it active and then adjusting it with the up/down cursor keys of your computer keyboard. Because the mixer has no gain, these faders only attenuate (reduce) the signal levels. The highest setting is 0dB, or Unity Gain. The default fader setting is the quietest setting, 144dB, which essentially mutes the audio. A pair of level faders may be "ganged" so that both channels may be adjusted together as a stereo pair. Also, at the top of each fader and meter is a fader level "fine adjustment" control. Clicking on the small "up" and "down" arrows will adjust the corresponding fader setting in 0.5dB increments. Next to each fine adjustment control is a numerical fader readout that is always current and active. PEAK METERS: Each peak meter indicates an audio signal level in "dB relative to full-scale." This means that a full-scale signal is referred to as "0 dB" and a signal that is 12dB "quieter" than full-scale is referred to as "-12dB." The meters are vertically color-coded into three sections: green, yellow and red. The green section represents a safe zone, ranging from approximately -48dB to -12dB. Most audio signals should appropriately fill this section of the meter. The yellow section ranges from -12dB to -3dB as the signal approaches a hotter level. For best capture resolution, recording in this area is both safe and advised. The red section of the meter ranges from -3dB to 0dB. On the input level meters, a 0dB condition indicates overload and audio clipping may occur. Therefore be careful to adjust the incoming audio levels so that they do not peak in the red section too long (you might use the monitoring capability of the Delta 1010LT to let your ears be the judge). On all output level meters, 0dB indicates full-scale output. Unlike the inputs, clipping is impossible on the outputs because of the 36-bit resolution built into the mixer hardware. MASTER VOLUME: At the left side of the Monitor Mixer page, you will see the Master Volume faders and peak meters. These faders have the longest throw and highest meter resolution of any level controls in the mixer page. They control the overall stereo level of the mixer output. The peak meters indicate the output signal levels with respect to full-scale and are directly affected by the settings of the master volume faders. MIXER INPUTS: The Mixer Inputs are inputs to the monitor mixer. These inputs accept hardware audio streams (directly from the Deltas analog and digital input ports) and software audio streams (digital audio generated in software to be output). This combination of streams makes the monitor mixer extremely flexible. Each mixer input channel has its own level fader and may be panned anywhere in the left/right stereo field. Each input also has its own peak meter. The peak meters indicate the incoming "pre-fader" levels of the incoming audio and are therefore not affected by the fader settings. However, the input faders do affect the levels of the signals exiting the mixer and you will see the affect of the input faders on the output "Master Volume" peak meters. Because of the large number of mixer inputs, not all inputs are displayed simultaneously. You may use the scroll bar at the bottom of the Delta Control Panel to scroll the view left or right. From far left to right the inputs are labeled "SM/ASIO 1/2 through SM/ASIO 7/8," then "SM/ASIO S/PDIF." These inputs accept the digital audio streams being sent from your software application (or the Sound Manager) to those driver devices. Each name begins with "SM/ASIO" to remind you that these are software streams and may not necessarily be routed to any physical outputs, and need to be connected (see Patchbay/Router Page).

3. The third option, "S/PDIF In," connects ports OUT1 and OUT2 directly to the hardware S/PDIF input on the Delta 1010LT PCI host card. The left channel of the S/PDIF In is routed to OUT1 and the right channel of the S/PDIF In is routed to OUT2. 4. The fourth option, "S/PDIF In (L/R Rev.)," functions identically to the third option, except that the left and right channels are swapped. Therefore in this mode, the left channel of the S/PDIF In is routed to OUT2 and the right channel of the S/PDIF In is routed to OUT1. 5. Selections five through eight connect the hardware analog inputs 1 & 2, 3 & 4, 5 & 6, or 7 & 8 (respectively) directly to the 1010LTs hardware analog outputs 1 & 2. For example, if "H/W In 1/2" were selected, any signal present at the IN1 port will be copied to OUT1, and any signal present at the IN2 port will be copied to OUT2. This same behavior applies to "H/W In 3/4," "H/W In 5/6," and "H/W In 7/8" when selected. The next three vertical columns of the Patchbay/Router page (from left to right), "H/W Out 3/4," "H/W Out 5/6," and "H/W Out 7/8," connect these hardware analog outputs to one of four sources. Since the three columns function identically, well use "H/W Out 3/4" as the example: 1. The default setting, "SM/ASIO 3/4," connects ports OUT3 and OUT4 to your music software or Sound Manager applet (provided that Out 3/4 is your selection for Sound Manager output. See next section, Hardware Settings Page). In other words, when music software plays audio to the device named "Sound Manager or Analog 3/4 Delta 1010LT" it will be routed directly to the "hardware" analog outputs 3 & 4 of your 1010LT breakout cable. 2. The second option, "S/PDIF In," connects ports OUT3 and OUT4 directly to the hardware S/PDIF input on the Delta 1010 PCI host card. The left channel of the S/PDIF In is routed to OUT3 and the right channel of the S/PDIF In is routed to OUT4. 3. The third option, "S/PDIF In (L/R Rev.)," functions identically to the second option, except that the left and right channels are swapped. Therefore in this mode, the left channel of the S/PDIF In is routed to OUT4 and the right channel of the S/PDIF In is routed to OUT3. 4. Options four through seven connect the hardware analog inputs 1 & 2, 3 & 4, 5 & 6, or 7 & 8 (respectively) directly to the 1010LTs hardware analog outputs 3 & 4. For example, if "H/W In 1/2" were selected, any signal present at the IN1 port will be copied to OUT3, and any signal present at the IN2 port will be copied to OUT4. This same behavior applies to "H/W In 3/4, "H/W In 5/6," and "H/W In 7/8" when selected. The rightmost vertical column of Patchbay/Router page, "H/W Out S/PDIF," connects the Delta 1010LTs hardware S/PDIF outputs to one of eight sources: 1. The default setting, "SM/ASIO S/PDIF," connects the S/PDIF Out port to your music software or Sound Manager applet (provided that S/PDIF is your selection for Sound Manager output. See next section, Hardware Settings Page). In other words, when music software plays audio to the device named "Sound Manager or S/PDIF Delta-1010LT," it will be routed directly to the

Eight faders are also available for setting each input and output level either individually or in stereo pairs. This should be considered an advanced settings page, useful when the source audio or target devices are diverse and need custom configuration. To access this second layer, click the button labeled Sliders located in the lower left-hand corner of the Variable Signal Levels section of the Hardware Settings page. Initially, the location of the faders will reflect the last radio button selection made in the first layer. After a change has been made in the second layer, the first layer will show no radio button selection, indicating that a custom setting has been made. You will notice when you access the second layer that the Input radio button is selected, giving us a set of eight faders that control input levels. Click the Output radio button to access the output faders. Also, you can click the Mono button to control each fader individually, or the Stereo button to control faders in stereo pairs. At any time, the individual faders may be set to vary the input and output levels of a particular port or ports. You can use the +4dBu, Consumer, and -10dBV buttons as a starting point, or operate independently of them. The faders can be set incrementally in.5dB steps, of which there are 18. If working in surround sound, these faders can be used to calibrate speakers for monitoring purposes. If using the 1010LT inputs or outputs for other purposes, the faders allow you to address multiple sources and targets individually.
The S/PDIF page of the Delta Control Panel configures the S/PDIF output format and displays the status of the S/PDIF input. To display this page, click the "S/PDIF" tab of the Delta Control Panel software. DIGITAL INPUT: This group box displays the current S/PDIF input status. The Delta 1010LTs S/PDIF receiver is capable of recognizing a valid input signal versus an invalid, corrupt or non-present one. When a valid signal is detected at S/PDIF In, this group box displays "Valid Input Detected." When an invalid signal is detected or no signal is present, the group box displays "Invalid or Not Present." Below this message are two grayed-out buttons: "Coax(RCA)" and "Optical." These are functions of the Delta DiO 2496, another product in the M-Audio Delta line, one with both optical and coaxial S/PDIF inputs. These controls do not apply to the Delta 1010LT. DIGITAL OUTPUT FORMAT: Within the "Digital Output Format" group, you choose the digital audio format of the S/PDIF output. The default setting, "Consumer," is a true S/PDIF format and is recognized by all consumer devices. The alternate "Professional" setting is an AES/EBU type data stream, but electrically S/PDIF. This is a work-around that is recognized by some but not all AES/EBU devices.

Note: For efficiencys sake, this step could have taken place while you were setting up the recording track assignments. However, since this step only affects playback and does not affect the recording setup in any way, weve placed it here to lessen confusion. This setting only needs to be made once, but may be changed if necessary. Assign software track 1 to output device "WavOut 1/2 Delta-1010LT" and pan the track (within your software) all the way to the left (hard left). Then assign track 2 to output device "WavOut 1/2 Delta-1010LT" and pan the track all the way to the hard right. Now, when you start playback, track one (mic #1) will be sent to the Delta software (WavOut) output 1, and track two (mic #2) to Delta software output 2 (you may also choose a panning scheme). These two software outputs are connected to the inputs of the monitor mixer, therefore the recorded vocal track channels will be sent to the monitor mixer, levels will be modified by the mixer and the output of the mixer will be heard at analog outputs 1 & 2. 18. Start playback from your softwares transport bar. Open the Delta Control Panel and go to the Monitor Mixer page. Observe the meters at "WavOut 1/2" these are the playback levels of your recorded vocal tracks. Adjust the faders and mute controls so that you may hear the vocal tracks at the appropriate levels and mix. These are the levels at which you may monitor the pre-recorded tracks while you overdub (record other tracks while listening to the first) additional parts. Lets assume that you like this take, and wish to overdub an additional harmony vocals. We can still use hardware inputs 1 & 2 of the Delta. Were set up to do so and theres no reason to change these inputs. Lets set ourselves up to overdub these next two tracks. We will record the next two tracks of material to tracks 3 & 4 of the software: 19. Back in your music program, set the source or input port to "Left PCM In 1/2 Delta-1010LT" on track three, and "Right PCM In 1/2 Delta-1010LT" on track four. Arm the tracks for recording. Track three is now set up to record the first microphone, and track four the second microphone. Usually at this point you would want to return to the Delta Control Panel monitor mixer to set up levels. However, because you will be recording the same instruments that you did on the first two tracks, you probably wont need to adjust input or monitoring levels. 20. Press record on your softwares transport bar. Record a take of your new vocal tracks. Because you have set up the first two tracks to play back through the monitor mixer, you should hear those original tracks along with the ones that you are now recording. 21. When you are done playing, stop the recording software and rewind the take. Before playing back what youve recorded, you will need to assign the newly recorded tracks to output devices on the Delta 1010LT. In your software, set the output ports of tracks three and four to "WavOut 3/4 Delta-1010LT." Now track three (first mic) will be sent to the Delta software output 3, and track four (second mic) to Delta software output 4. 22. Press play on your softwares transport bar. Understand now that the four

recorded tracks from the software are being sent to WavOut 1, WavOut 2, WavOut 3, and WavOut 4 simultaneously. Therefore they are all being input to the monitor mixer and their playback levels can be controlled at the corresponding channels of the monitor mixer. Open the Monitor Mixer page of the Delta Control Panel and adjust the levels of the four channels according to your taste. You may also experiment with the Mute and Solo controls while listening to the playback. Note also that the mixer continues to monitor the microphones at analog inputs 1 & 2. At this point, you should be able to see how this multi-tracking session is developing. As we add more tracks within our music software, we set them to the next pair of Delta software outputs (3/4, then 5/6), and bring up the faders of those software inputs in the monitor mixer (WavOut 3/4, WavOut 5/6). We continually monitor from the Delta hardware outs 1 & 2, via the Mon. Mixer setting as the monitor source in the Patchbay/Router page, and adjusting our mix of the software outputs (and the way we monitor our guitar and vocal at the inputs) via the Monitor Mixer settings. Notice that if we continue to overdub past track 8, we run out of WavOut devices to assign to. In this case, you may want to do some of your level mixing within the software application if it supports it. Most applications will allow you to assign more than one track to an output device and then set the relative levels of the tracks within the software, letting the software do the mixing. In this example you could have assigned all of the playback tracks to "WavOut 1/2" and let the software handle the mix.

Typical Setup #2

Lets look at a setup that involves a typical transfer of information from DAT to computer and back to DAT. Here, well be using the Delta 1010LTs S/PDIF I/O, plus one of the analog output stereo pairs. For this setup, we will connect a DAT to the Delta 1010LT PCI Host card using coaxial S/PDIF cables (75-ohm impedance RCA-to-RCA). Well also connect the 1010LTs analog outputs to a sound system for monitoring purposes. A setup like this might be used to transfer a number of mixes from a DAT into an audio editing program, performing the appropriate edits, and then transferring the edited material back to DAT.

Troubleshooting

This section addresses potential problems that can occur in all operating system environments, with emphasis on hardware troubleshooting. Within the PC environment there are a limited number of hardware resources (I/O addresses, IRQs, and DMA channels) available for use. Since audio cards require many resources, most audio card installation problems arise from unavailable or improperly set resources. This is important enough to repeat: IMPORTANT: Most sound card installation problems result from attempting to use system resources (IRQs, address locations) already in use by other hardware (or software acting as virtual hardware) in the system. The Delta 1010LT has been carefully designed to minimize the number of resources consumed (it requires just one IRQ and does not require any DMA channel resources). It is also capable of sharing an IRQ in some cases. However, the possibility of resource conflicts still exists due to the nature of the Windows environment. Many resource conflicts are automatically recognized by Windows Plug-and-Play (PnP) system. When a resource conflict is detected, it is displayed in the Windows Device Manager. The Device Manager places a yellow exclamation point on top of the icon associated with the problem device. For an example of how the Device Manager should look when a Delta 1010LT is successfully installed, see the "Verifying Windows Driver Installation" section of this manual. If a yellow exclamation point does appear over your Delta 1010LT icon, you may have a resource conflict. There are several ways to approach this problem. NOTE: When resolving conflicts between PnP and non-PnP devices, it is recommended to re-adjust the resource settings of the non-PnP device first. Typically, Windows is only aware of the resource settings of the installed PnP devices and has no information available to it for adjusting the PnP devices resources around those of the non-PnP devices. The exceptions to this are when: (1) a non-PnP device has a true Windows 98/95 driver written for it, (2) the BIOS setup allows reserving an IRQ for a legacy device as opposed to a PnP device, or (3) resource requirements for the non-PnP device have been manually entered into the Windows Device Manager. In these cases Windows is aware of the non-PnP devices resource requirements. One of the quickest ways to change the resources assigned to a PCI card like the Delta 1010LT is to merely relocate the card to another PCI slot. Before doing so, it is a good idea to locate the device in the Device Manager, highlight it, and click Remove (in 95/98) or select Uninstall from the Actions menu (in Win 2000). With the computers power off, remove the Delta 1010LT from its current PCI slot, move it to another available PCI slot, and turn your computer back on. More often than not, this will change the IRQ assignment of the Delta 1010LT when you re-enter Windows. After returning to Windows, follow the steps outlined in the "Verifying Windows Driver Installation" section of this manual. It might take more than one PCI slot relocation to find an open IRQ.
