Beno S56KZN and Aleks S56AL have created a modification for the M110 to make it a lot more useful. Check out their work here.
For a programming cable pinout, look here.
The Radius M110 is NOT a Maxtrac! This radio was built by Motorola Gmbh. It is a kind of MC Micro with a special CUP in it. Unlike the MC Micro, the M110 VCO's will lock on the whole ham band (10Mhz).
To program, you use the MC Micro cable. You can program the radio via the mic plug (Not a RJ45 but a RJ12 6pins) or the head connector (DB15). MC Micro RSS (Eva or Eza) version will NOT work with M110, you must have relevant M110 RSS.
The Radius T340 is (was) used in the U.K on the now extinct National Band 3 radio service. Superficially, it looks like the MC Mciro/M110 with a full keypad head and LCD display. It operated on 174-225 MHz using MPT1327 trunking. It uses different RSS than the MC Micro/M110 radios, but it is programmed with the same cable(s) as the MC Micro/M110. The DB9 accessory connector for the T340 is the same as below for the MC Micro/M110. The part number of the service manual is 688482D64.
The pinout of the M110 DB9 accessory connector is the same as the MC Micro, but external alert is not switchable (permanent in the M110).
J5(DB9) PIN DESCRIPTION 1 PTT INPUT 2 AUDIO GND INPUT 3 GND (Hang up optional with jumper) 4 SPEAKER Hi Pot OUTPUT 5 SPEAKER Lo Pot OUTPUT 6 MICROPHONE Hi Pot INPUT 7 BUFFERED RX AUDIO OUTPUT 8 EXTERNAL ALERT OUTPUT 9 EMERGENCY SWITCH INPUT
The pinout of the DB15 Control Head connector is as follows:
J4(DB15) PIN DESCRIPTION 1 CALL(Spare) 2 PTT 3 Vol Cont HI 4 Audio GND 5 Spkr Hi 6 B+ 7 HUG/PGM 8 F1/F2(DATA2) 9 Tx Busy (RESET) 10 Mic Hi 11 Vol Cont Wiper 12 Spkr Lo 13 SW B+ 14 GND 15 CSQ/UNSQ(DATA1)
The pinout of the Mic connector is as follows:
J1001 (RJ12) PIN DESCRIPTION 1 HUB(HOOK)/PGM 2 RX audio 3 PTT 4 Mic Hi 5 AUDIO GND 6 GND
Count from the dot (1 is closest) at the front of the microphone connector. Or, cable inlet going away from you locking tab upwards, contacts facing down count from left to right.
