This input is intended for injecting signals into the transmit path. This is a digital output for External Alarm / Fault Indication active low open collector This is a digital input to trigger external PTT active low non active high Is 660 ohms and the AC impedance is 560 ohms. Signal is independent of the microphone signal on the microphone connector.

The service manual of the MTM800 provided the answer.

Perhaps good for serial data communication, but not for programming. The USB cable as sold via the internetĪ closer study of the cable showed that the pinout of the connector was incorrect. Anyway, my first action was to cut off the USB connector with integrated level converter. But via the internet also bare accessory connectors are sold for far less money. So as I already owned that cable I’ve continued my project with it. Not a real bargain, but I got fooled by the rumor the MTM800 could be programmed via the USB interface. Those cables change owner for about 30 Euros. Via the internet USB programming cables for the MTM800 are offered. With the exception the Tetra radio has some more pins. A similar connector can be found at the GM300 or the TM900 series. To program the MTM800 the accessory connector at the backside of the radio is to be used. But this is also the most expensive solution. The easiest way is to purchase all accessories from Motorola. I became aware of this after obtaining a Motorola MTM800. Programming Motorola Tetra radios is not always easy.
