Supporting the Kenwood KDS-100 /w Merlin AVL

Modifications To Kenwood TK-x80 Mobile Radio

When you are installing both a KDS-200 Data Head and a Merlin 2017 AVL unit onto
the same radio, some modifications have to be made to get all proper signals to the KCT-
19 connector. When you are connecting a KDS-100 without a Merlin AVL unit to a
radio, you normally use a KCT-34 option connector. In this case you will be using a
KCT-19 option connector kit. You will have to perform the following modifications to
the KCT-19/Radio to connect all required signals to the KCT-19 output:
1) Remove the Red wire from pin 2 of CN1 and solder this wire to pin 3 of CN2 in
the TK-x80 radio.
2) Remove the Orange wire from pin 3 of CN1 and solder this wire to pin 2 of CN2
in the TK-x80 radio.
3) Be sure to install the "E" lead of the KCT-19 into CN-4 of the TK-x80 radio.
Once the above modifications are complete, you will have all necessary signals available
for both the KDS-100 and the Merlin AVL at the KCT-19 15 pin connector. From this
point you will need to install the 7525-10-1044 "Y" cable to split the necessary signals
between the KDS-100 and the Merlin AVL. Plug the 7525-10-1044 "Y" cable into the
KCT-19 from the radio.

KDS-100 Modifications

The KDS-100 connects to the KDS-100 side of this 7525-10-1044 "Y" cable. Your
KDS-100 will need to be programmed for "PC" mode.

Merlin AVL Modifications

The Merlin connects to the 2017 Merlin side of the 7525-10-1044 "Y" cable. No changes
are made to the interface of the Merlin AVL to the KCT-19 vs. the interface of a Merlin
AVL to a 7525-10-1044 "Y" cable.
1) Rather then inserting the Grey wire from the Merlin AVL into pin 15 of the
Kenwood Connector, Insert the Grey wire from the Merlin AVL into pin 1 of the
Kenwood Connector.
