IP-223 to Kenwood Radios 1
1 General
The application note is intended to show how to assemble the cable and setup the hardware of
the IP223 for channel change and FleetSync applications using Kenwood radio.
2 Setup
2.1 TK-x150/180 Model Cable Assembly:
NOTE: There are differences between the TK-x150 and TK-x180 radios DB25 connectors.
If COR is used, pin 20 (TK-x150 an output only) will be programmed for that function and
the cable will route that signal to the IP-223. On the TK-x180 the same pin is a general
purpose I/O and has an additional 470 ohm series resistance added. This requires that the IP223 external pull-up resistance must be removed. Jumpers J8 (Line 1) and J30 (Line 2)
should be placed in a neutral position (neither A or B, hanging).
The tables below show the assembly cable for the TK-x150 model radios.

For IP223 Rev F board or later make sure jumper J35 is in “A” position for line 1 and jumper
J26 is in “A” position for line 2.

2.2 TK-x80 Model Cable Assembly:
The KCT-19 accessory cable from Kenwood radio is needed and the 'E' connector is
connected to CN4 inside the radio to establish the serial communication.
