Yes I always use the pigtails with emitters.
Yes correct port routing.
Got the codes from the dealer section of the Netstreams website.
The interesting thing is that if you send an IR signal from a remote (T-2C, M2) to a Netstreams keypad with an IR target it works fine. If you do the same with the IR linx it is also fine. It is only when it gets a signal from an emitter connected to the RP-6!
