Sangoma Cable Pin-outs

Please Note: The + sign means there is a connection between two wires.


601 S502/S503 back-to-back cable

  • Used for back-to-back connections between two Sangoma card in the RS232 mode.
  • Set both cards for Internal Clocking and set the line speeds for 56 kbps max on all cards. Note that the S508 will not run correctly on this cable.
