Connect Gps35-Hvs Using Kct-31 - Kenwood TK-7160 Modification Information

2.7 Connect GPS35-HVS using
KCT-31
This section describes how to connect the
GPS35-HVS to the TK-7160/ TK-8160 by using
KCT-31.
Required Items to Connect the
GPS35-HVS
Transceiver
•
KCT-31
•
• GPS35-HVS
THE TRANSCEIVER MUST BE TURNED OFF AND THE
POWER CABLE MUST BE REMOVED BEFORE
INSTALLING THE GPS35-HVS IN THE TRANSCEIVER.
The Garmin GPS35-HVS is a suitable GPS unit for
installing in the TK-7160/ TK-8160. GPS35-HVS must
output RS232C data at CMOS logic level. A modified
KCT-31 is used to convert the RS232C level to CMOS
level.
KCT-31 also must be modified to supply 12 V to the
GPS35-HVS so that it can be connected to the
TK-7160/TK-8160.
AFTER MODIFYING THE KCT-31, LABEL IT
APPROPRIATELY TO AVOID CONNECTING THE
MODIFIED KCT-31 TO A PC OR A LAPTOP COM PORT.
Once the GPS unit is installed in the TK-7160/
TK-8160, the GPS unit can be programmed to send
the vehicle location to a TK-X80/ TK-X180 series
transceiver that is used as a base unit interfaced to a
PC running FleetSync, compatible AVL software.
2.7.1 Programming GPS35-HVS
The GPS35-HVS must be configured using the
software supplied by Garmin. In addition, the
GPS35-HVS must be powered with 12 V from an
external source.
Normally, the D-sub 9-pin connector on the PC side is
male, and the D-sub 9-pin connector on the modified
KCT-31 side is female. A programming jig (Gender
changer) should be made in order to interface to the
GPS35-HVS connector.

2.7.2 Installing a D-sub 9-pin
Connector (male) on the
GPS35-HVS
1. Strip and tin the red, black, blue and white wires
from the GPS35-HVS.
2. Solder the blue wire to pin 2 of the D-sub 9-pin
connector (male).
3. Solder the white wire to pin 3 of the D-sub 9-pin
connector (male).
4. Solder the black wire to pin 5 of the D-sub 9-pin
connector (male).
5. Solder the red wire to pin 9 of the D-sub 9-pin
connector (male).
2.7.3 Preparing a Programming Jig
A specialized programming jig should be made in
order to program the GPS35-HVS. Prepare 2 D-sub 9-
pin connectors (female) for the parts.
1. Connect each pin 3 of the D-sub 9-pin connectors
(female).
2. Connect each pin 2 of the D-sub 9-pin connectors
(female).
3. Label and write "Garmin GPS-35HVS side only" on
one of the 2 D-sub 9-pin connectors.
4. Connect the black wire to pin 5 of the connector
labeled "Garmin GPS-35HVS side only".
5. Connect the red wire to pin 9 of the connector
labeled "Garmin GPS-35HVS side only".
6. Connect the black wire to a ground terminal on the
12 V power supply.
7. Connect the red wire to the + terminal on the 12 V
power supply.
