If connections for pins 2 and 3 are reversed, then you can correct this by re-soldering pins 2 and 3 wires to a straight-through configuration. If they do, it is a straight-through serial cable. Make sure that each pin corresponds to the same hole on the header connector. The only pins that matter for the NX-8E are pins 2, 3, and 5. The 0-pin to DB9 serial cable is connected to the serial header so that its connector is plugged into the NX8E board with the red edge of the ribbon cable (pin 1) facing towards the bottom of the board. This has been tested with a 10-pin to DB9 serial cable, straight through serial cable, and gender changer. The following information about configuring the NX-8E panel came from here: still trying to get the alarm panel to work so if anyone has LinuxMCE configuration help, please include it here. You will also need the GC100 to connect the alarm panel to the network unless you plan on connecting it directly to a serial port on the core. Make sure that the part that connects to the alarm panel's header does not have a plastic block on the last pin (slot #10 - this is unused in a 9-pin connector), otherwise it will not fit into the board.

IMPORTANT: Your first post will be checked for appropriate content. You can get this cable from computer or electronics stores.

To connect the to the LinuxMCE system, you need a RS-232, P-0003 straight-through serial cable that will connect to the serial header on the NX-8E main board.
