Default 6250 and 4651

Just installed an FC6250HK and SPM4651T in a Trex 550 and not getting anywhere with them. The bind went fine but after that nothing. Attempted to go into Forward Programming and just get a "Navigation Timeout" message. No movement of the servos, nothing. Upon power I get a green flashing lite and solid bind lite on the 6250.
The documentation talks about an additional SRXL2 but with only one 4 pin connector where would another remote plug into. This is all with an IX12 transmitter on the latest upgrades.

Any ideas would be appreciated

The green flashing led indicates the 4651t is communicating, red flashing is failsafe or no remote receiver. The 4651t connects to the data/bind/rx2 port on the front.

Is the tx showing telemetry? You can look at the flight log and if it is showing L: 6250 then the fc6250 flight log is being displayed. The value next to R: is the # of remotes connected.

The fc6250 initial settings are servos disabled to avoid damaging servos by operating them at the incorrect frequency or by having the wrong swashplate type selected.

Just for troubleshooting, if you have a older dx fwdprg capable (airware 2.05) radio around try binding to it and see if fwdprg connects.
