Does anyone happen to know the pinout of the FY-4 programming cable for the Pyramid SVR-250? It looks like an RJ-11 connector inside the unit, but I haven't been able to find any information on the cable itself.

Is the service manual any help? They have it on their site, under Product Support.

The schematic in their service manual is for Rev L of the controller board, my unit is apparently Rev D. The "L" version shows a 2.5mm programming connector on the board, which doesn't exist on mine; it has an RJ-11 instead.

SVR-250 manual, first schematic lower left corner shows RJ11 programming jack. Were you maybe looking at the SVR-200? Those had a 2.5mm jack.
