Hello, Was wondering if anyone happened to know how the programming cable is wired for the above pyramid in vehicle repeater ?
Cable has a part No. of " FY-1 " I don't know if the Genuine version has some electronics inside the DB9 plug cover as with the T800 SII that changes levels, etc. The unit has a 2.5mm jack to accept the data from the computer and a db9 plug at the other end to connect to the serial port at the computer. I have a standard RS232 interface box i use for Tait stuff that provides Tx, RX, Gnd outputs but i was wondering if it would be as simple as l + R + ground on the 2.5 stereo plug. I have seen the file that uses the Motorola programming box at the Batlabs site but if i could avoid having to purchase one of those solely for this use i would prefer it. Any info or suggestions gratefully received.
