Hey Guys, curious to know which port you use to power the AMBrc transponder with the SR3300T?

I cant seem to get mine to work and am starting to worry its my AMB?

Thanks, Paul

Any free port should work.

if the steering servo is working fine, pull that plug and put the transponder's plug in there. if the light doesn't come on, it's the transponder.

Thanks for the suggestion - It worked in the STR but not in the LAP port for some reason. Ended up putting it into the Bind port and seems to be OK.

My RPM telemetry is not working so might be the LAP and RPM ports on the RX ...

Thanks again, P

THe LAP port is for a on board counting system that Spectrum sells seperatly. Just plug the pt into the third channel port.

I am using this same setup and am also running an external BEC that is plugged into the AUX channel. The ESC is plugged into the THR channel, and the steering in the STR of course. Is it possible to run the transponder on the BIND/RS port (since this is the only free port besides the telemetry ports)? Thanks guys for your help

The AMB will work on the Bind port, as well as the thr/str/or aux.

The issue youre having is that that telemetry ports do not have the same voltage as the ports meant for servos, and thereby do not have enough power to turn the AM on.

Telemetry ports are regulated to 3.3v and must not be used to power it according to the instructions. Therefore I'm thinking of binding it using the bind plug in the BIND/RS port and power in AUX. Once bound, I will power it off, remove bind plug and plug switch into BIND/RS and PT into AUX.

BIND/RS - BEC/Batt
STR - Steering
THR - ESC (minus the + lead wire)
AUX - Transponder

Has anyone tried this setup? Thanks

That should work just fine

Thank you sir, appretiate it

Or you can make it one step simpler and just plug the transponder into the BIND/RS port. That way, if you ever need to rebind again for some reason, instead of unplugging the transponder and moving the switch back over to AUX, you only need to unplug the transponder from the BIND/RS port. What I have done is connected a short extension wire to the BIND/RS port and have the other side outside the receiver tray. That way, I can easily connect/disconnect a transponder or do a rebind without ever having to open the receiver tray.

Cool. Thanks for the tip! I ended up doing that. Final configuration was:

BIND/RS - PT
STR - Steering
THR - ESC (minus the + lead wire)
AUX - BEC

You are right it's easier Everything works spiffy with this configuration for anyone else in the future who wants to know. Thanks for your help guys.
