Radio Programming

The following list identifies the major differences between a TK-x80 and TK-x180

installation. If you are already familiar with TK-x80 installation, this list can help you

prepare for TK-x180 installation.

• TK-x180 radios do not have a dedicated external PTT line. This function must be

defined and assigned to one of several possible programmable AUX I/O pins on

the DB-25 connector. This function and pin assignment must be made to pin #13.

This pin is also that configured for the PTT line in the custom cable supplied by

Zetron (part number 709-7823). Please ensure these match in the radio

programming software.

• When using the TK-x180 in a system employing the PassPort trunking protocol,

it is highly recommended that the receive voice audio delay in the Model 360 be

enabled. When the delay in the Model 360 is disabled, it is possible for the FSK

burst identifying the radio transmitting to disrupt the voice audio as much as two

seconds into the call.
