3Drobotics combined Telem/OSD cable

Hi guys,, I received a couple of the combined Telem/OSD cables from 3DR..They only have 4 wires going from APM to Telem?? The standard cable (that comes with Telem radio) has 5 cables...The pin that misses out is labelled RTS....It seems to work... But am I going to be missing some functionality???CheersBob

  • Thanks Bill,, yeh I was just a bit concerned as the standard cable uses 5 wires,, at both ends,, but that might be just because the DF13 port is a 5 wire port,, and they just bought a truck load of 5 wire DF13's??

    The APM only use three wire Serial Links, which is Tx,RX,GND, the forth is 5V power supply.
