    Hi

    I have a UM1625 video modulator (Astec International) in my junk box, but no wiring diagram can be found. All the references Google turns up are for sales, but no specs.

    The only information I have is that it takes 5vdc, has 3 wires coming out of one end and an RCA connector at the other end for composite(?) video input. Presumably the wires are Gnd, +5, and antenna, but there are no markings to indicate which wire is which.

    Any information on the device will be appreciated. Otherwise it's the bin with it.

    TIA
    Jim
