Protocol Support

The WiPort uses the widely accepted 802.11g protocol to connect to a wireless infrastructure or ad-hoc network, and is fully backward compatible with legacy 802.11b wireless networks. It uses the Transmission Control Protocol (TCP) to assure that no data is lost or duplicated and that everything sent to the connection arrives correctly at the target. Other supported protocols are listed below: ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for network communications. TCP, UDP, and Telnet for connections to the serial port. TFTP for firmware updates. IP for addressing, routing, and data block handling over the network. User Datagram Protocol (UDP) for typical datagram applications in which devices interact with other devices without maintaining a point-to-point connection.

Disclaimer

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. This device is intended only for OEM Integrators. The OEM integrator should be aware of the following important issues. Labeling of the End Product The end product to integrate this module has to be clearly identified on the label that this end product contains an FCC approved RF module. The format of such statement could be "Contains Transmitter with FCC ID: R68WIPORTG" or similar. RSS-GEN Sections 7.1.4 and 7.1.5 Statement for Devices with Detachable Antennas This device has been designed to operate with the antennas listed in the Certificate, and having a maximum gain of 5 dB. Antennas not included in this list or having a gain greater than 5 dB are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that required for successful communication. Integration Note a) This module is authorized under limited module approval specified to mobile host equipment. So, the antenna must be installed such that 20cm is maintained between the antenna and users. b) The transmitter module may not be co-located with any other transmitter or antenna. As long as the 2 conditions above are met, further transmitter testing will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emission, PC peripheral requirements, etc.) Note: In the event that these conditions can not be met (for example certain laptop configurations, general purpose PCMCIA or similar cards, or co-

location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product (including the transmitter) and obtaining a separate FCC authorization. Note: Changes or modifications to this device not explicitly approved by Lantronix will void the user's authority to operate this device.

Serial Input/Output

The unit has two serial ports compatible with V24 serial standards at data rates up to 921Kbps. The serial I/O signals are 3.3V CMOS logic level and pins are 5V tolerant. Serial signals connect to an internal device, such as a UART. For evaluation and prototype work, it is convenient to have an external RS-232 interface that can connect to the serial port on a PC. The WiPort Evaluation Board has one RS-232 and one RS-232/422/485 transceiver (level shifters) to implement this external interface (only the WiPort 485 supports the RS-422/485 interface). If desired, use the CPs to create a DTE or DCE-style interface using any 3 available CPs. To create these interfaces, connect the signals according to Table 2-3 and Table 2-4. Note: CPx, CPy, and CPz are any of the available CPs.

WLAN Input/Output

The following table displays the WLAN input and output functions.

Table 2-7. WLAN Signals Pin Number Pin Function WLAN Power LED (WiPortB only) WLAN Activity LED
WLAN Power LED can be used to drive an external LED to monitor the status of the radio. When the WLAN Power LED is on continuously, it indicates the radio is on and in normal mode. When it is blinking, it indicates the radio is in power saving mode. WLAN Activity LED is also used to drive an external LED to monitor the status of the radio. When the LED is blinking, it is receiving or transmitting wireless data. When it is off, it indicates there is no wireless activity.

WiPortB

WLAN Power LED output can be used to drive an external LED to monitor the status of the radio. The output is active when the receiver and or transmitter are on. WLAN Activity LED output can be used to drive an external LED to monitor the activity of the radio. The output is active when an actual packet is received or transmitted. Both outputs are active high and can drive LEDs with 4mA. The LED shall be connected between the output and ground with a series resistor of 220 ohm.

WiPortG

Pin 36 is reserved. WLAN Activity LED output can be used to drive an external LED to monitor the activity of the radio. The output is active when the receiver and or transmitter are on. The output is active low and can drive an LED with 4mA. The LED shall be connected between the output and 3.3V with a series resistor of 220 ohm.
Note: If you have questions or concerns, please contact Lantronix Technical Support at (800) 422-7055 (US only) or (949) 453-7198. For both WiPortB and WiPortG, if power management is disabled, and when the unit is associated with a network, the receiver will always be on and thus any LED output, that indicates the receiver or transmitter being on (Power LED on WiPortB and Activity LED on WiPortG), will be active continuously.

Ethernet Input/Output

The following table displays the Ethernet input and output functions.
Table 2-8. Ethernet Signals Pin Number Pin Function Ethernet TX+ TXTX Center Tap RX+ RXRX Center Tap Status LED1 Status LED2
Ethernet communication lines connect to external magnetics and an external RJ-45 jack. They are used for the creation of an Ethernet interface (instead of using the wireless interface). Either Ethernet or WLAN is selectable for communication (not both). Ethernet Link LED 1 can be used to drive an external LED. The LED is on when a link exists. Ethernet Activity LED 2 is also used to drive an external LED. The LED blinks when activity is present.

Serial Interfaces

The WiPort serial interfaces are 3.3V logic level and typically connected to a Universal Asynchronous Receiver/Transmitter (UART). For connection to an external device, the evaluation board has RS-232 and RS-232/422/485 transceivers. Port 0 supports RS-232. Port 1 (channel 2) supports RS-232/485. Connect to a PC using a null-modem serial cable with 9-pin connectors (F/F). The table below lists the RS-232 signals and corresponding pins on the WiPort. Note that the WiPort data and hardware flow control signals are actually buffered by the evaluation board CPLD. All signals are level-shifted by the RS-232 transceivers.

Power Supply

The evaluation board uses an external 3.3V regulated supply (included with kit). The evaluation board contains additional filtering and protection.

General Control PLD

The following table denotes the configuration of the evaluation board. Configuring the jumper re-routes the signals on the evaluation board as required for a given product. This also drives the LEDs.
