    Default Sepura STP8X programming cable

    Hi,
    Does anyone have information on how to build a programming cable for Sepura STP8X-series radios?
    It attaches to the side connector and that connector is different from the normal STP8/9000 -series connector.

    My guess is that it's straight USB but can't be sure.

    Any advice?

    FTDI chip board is required, some people say that only RXD, TXD, GND need to be soldered

    Sorry, could you post the picture somewhere else? It seems I don't have the rep power needed to view attachments.

    easier... I build such cable... you need a UBS to TTL HW 597 on 3,3V and the adpter for the radio. Only 3 pins TX, RX an GND.
    Best regards!

    Sorry, the given pinout above is for STP8000/STP9000. Not for STP8X (ATEX).
    I need the pinout to build a programming cable for STP8X, it connects to the side connector (RAC), it doesn't have a bottom connector (FAC).
    It's 14pin, whereas the STP8000 FAC is 2+16pin and STP8000 RAC is 11 pin.

    Best regards,
    Martin

    Once again, STP8X, not STP8000.
