Motorola Waris Series
Most Motorola mobile radios in the Waris series (CM and CDM models) use the same pin-
outs for basic interfacing via a 16-pin accessory connector on the rear apron. A number of
the accessory pins are programmable in the radio using Motorola’s closely guarded CPS
programming software.
Of note, Pin 8 on a conventional radio must be programmed for combined PL/DPL AND COR
indication; on a trunked radio select Talkgroup Activity.
Pin 11 must be programmed to provide squelched audio with constant level.
Program the radio to use Pin 2 which is a mic level input that will provide limiting with pre-
emphasis and use Pin 3 for external PTT.
Interface Cable
There are several eBay sellers offering interface cables for Motorola radios. At a minimum
look for a 5-wire cable with a 16-pin accessory plug on it that fits all the CDM and CM series
Motorola mobile radios.
Because some 16-pin plugs are not keyed, care must be used when inserting it into the 20-
pin receptacle on the CDM1550 radios, being certain to center the plug; that is, leave 2 pins
bare on the left and 2 pins bare on the right so that the plug sits in the center 16 pins of the
radio.
