Not sure what else to tell you other than make sure you are giving the receiver +5v (or +3.3v) and not the servo battery voltage. Likewise make sure that the signals are plugged in the right order. On My Arc32 I am not using the PS2 cable, but instead using the equivalent of the cable kit: http://www.lynxmotion.com/p-714-ps2-con ... e-kit.aspx
(can make with two servo extension cables). I then end up putting a piece of tape on the PS-2 receiver and write the signal names on it. That way I usually don't get the signals messed up... Example:

If it were on my machine I would hook it up to a logic analyzer and see if it is responding at all. So far it does not look like it is receiving.
