Has anybody successfully aligned a VX4000/5500/6000 using either a FIF-10 or FIF-12?
The official SCV49 alignment cable for a FIF-12 is a Motorola T9101628 alignment cable...which is basically a DB25 and a DIN plug and maybe a resisitor?
I have an old CT-88 alignment cable (for use with a FIF-8) which uses an 8 pin MINI-DIN not a standard DIN plug...so I can't plug in directly into my FIF-12 without modding the cable....and there is also a resisitor on pin 9 of the DB25...not sure of its value as it is encased in heat shrink...will need to measure it when I get a DIN plug for the alignment cable/ FIF-12). Also does the latest official T9101628 alignment cable for a FIF-12 still use a resistor on pin 9 of the DB25 plug or is it only with the CT-88 alignment cable and FIF-8 set up?
The pin outs on the DB25 (from the service manual) are Pin 9 TXD (plus resisitor), Pin 10 RXD and Pin 18 GND. I will need to work out the pin outs on the FIF-12 DIN..I guess using one of my programming cables...I'm not sure which Vertex radios use 3 wire RXD/TXD/GND vs 2 wire programming pin outs to work out the FIF-12 DIN TXD/RXD/GND pin out...maybe the later DMR stuff such as an EVX539?
