This interface is set up for the use of a data channel to be used for the Trakit data. It is not necessary to use this feature if it is not needed or available. The 2ND PTT output can also be used to mute the speaker of the radio. This would require different radio programming as well as different wiring for the green wire (speaker mute).
RADIO PROGRAMMING NOTES: Under main radio parameters, set the UI OPTIONS for AUDIO RX and AUDIO TX both for MODE 1. PTT REQ N = DATA REVERT INPUT A = DATA ARQ OUTPUT A = CLEAR TO SEND OUTPUT B = RX DATA GROUP Assign the data system/group under the banks. Under the UI OPTIONS on the data system, assign AUDIO TX as MODE 3. Also, designate the appropriate group in that system for data. Voice must be on one system, and the data must be on another system. Therefore, system scan is needed. This is because the Summit TX AUDIO MODES are selected on a system wide basis. MODE 1 is the default mode for normal voice operations. MODE 3, and other modes are for routing the transmit audio from external devices into the radio.

The following steps outline the procedure for interfacing the Kenwood TK-880/980/981 radio to the TrakIt-20. 1. The enclosed interface cable needs to have one pin installed in the appropriate location. This cable can be used for a variety of applications. For a Kenwood TK-840/940/941, install the loose pin (brown wire) into Pin 10 on the molex end of the interface cable (speaker mute). For a TK-880/980/981, the loose pin can be used for speaker mute or for data channel selection. Insert it into Pin 2 of the molex connector for speaker mute. Insert it into Pin 15 of the molex connector for data channel selection. If data channel selection is used, the Trakit-20 can automatically switch the radio to the system/group that has been designated for data. In data mode, the radio mutes the speaker automatically when the data system/group is selected. This is a function of radio programming. The desired system/group must be designated for data. 2. Set the TrakIt-20 up for a bench test and use the AVL Installer program to set the following operating constants in the installer table to the indicated value: Transmit indicator active: Receive indicator active: PTT output active: Enable mic mute gate on transmit: Enable Tx indicator as event 2: External output active: External output mode: Low Low Low Yes No High/Low Speaker mute/ Second PTT

MAKE SURE THAT THE RECEIVE AUDIO IS SET FOR FLAT. If the receive audio is not set for FLAT and it is set for FILTERED, the RX AUDIO MUTE signal will mute the rx audio to the Trakit and it will not function. If FILTERED audio is used, the wire going to pin 6 on the radio accessory connector must be removed and JP4 must be moved to the AB position. Doing this will disable the speaker mute function of the Trakit.

It may be COR only - active low. This application note was done with HLN8070D logic board. Note: If the microphone being used with the GM300 radio is a newer version and has power and/or transmit LEDs, be aware that it may have an effect on the TX audio level from the TRAKIT-20. The level will change as the microphone is plugged in or removed as it tends to load down the TRAKIT-20s audio output.

3. Change R20 in the Trakit to a 1K resistor. 4. There are several wires that need to be inserted to the 12 pin Molex connector on the back of the radio and soldered to various points in the radio. They are as follows: 1. Solder the tinned end of the RED wire to IC251 pin 2 and insert the pin into pin 12 of the Molex accessory connector. 2. Solder the BLACK wire to the GROUND lead of the power cable and insert the pin into pin 11 of the Molex accessory connector. 3. Solder the ORANGE wire to the junction of Q105 and R130 and insert the pin into pin 10 of the Molex accessory connector. 4. Solder the BROWN wire to the Blue wire on W4. (W4 plugs into J3) and insert the pin into pin 9 of the Molex accessory connector. 5. Solder the YELLOW wire to J603 pin 5 on the Logic board and instert the pin into pin 8 of the Molex accessory connector. 6. Solder the BLUE wire to the Orange wire on W4 and insert the pin into pin 7 of the Molex accessory connector. 7. Solder the GRAY wire to the junction of Q105 and R130 and insert the pin into pin 6 of the Molex accessory connector. 8. Solder the WHITE wire to the White wire on W5 and insert the pin into pin 5 of the Molex accessory connector.

***Note the 100K resistor in the TX audio line. It should be installed in the hood of the DB15 connector between pin 2 and the blue wire. The wire from pin 6 (Mic Mute) is connected to the junction of the blue wire and the 100K resistor. The blue wire is connected to the pad in the radio that the circuit trace connects to J1003 Pin 2.
