Programming a GS14 internal UHF Radio

Hi All, I need to program some new frequencies into the Satel?ÿ internal radio on a GS14.?ÿ ?ÿThe GS14 came with a DC5 collector, which does not have the full functionality to program the radio.

I have the required software from Satel, but not the Leica GEV261 cable.?ÿ The cable sells for $550, which I don't really want to pay.?ÿ I can buy the LEMO connector for less than $50.?ÿ I have tried to pigtail a 3 wire connection to the GS14 LEMO with no success.

Does anyone have a GEV261 cable who would be willing to use an ohm meter on it and see if it uses more than just three wires??ÿ I will be glad to call you and work through it with you.?ÿ Thanks!?ÿ Jim
