exceed rc tx question

I have the 2.4ghz exceed rc tx and trying to set up a g401b gyro on my HK heli, will this gyro work with this TX? The gain lead is set to ch 5 and gyro on 4. The gyro will not switch to HH. It iniatilizes but the light doesn't stay on, which is normal mode... Can I use ch 5 variable knob to adjust gain or does this need to be set up differently. Confused. The config program doesn't give me an option to set up the gyro.
Thanks for any help.

I had the same problem and I was never able to figure out how to make it work with a gyro the needed the remote wire plugged in to work right. I had to use the Telebee gyros because they work with everything.

Hmmmm ok thanks. Whats weird is I can get HH to work on my stock Esky gyro from my belt cp v2. By adjusting the knob I can turn it on/off. But not at all with the g401b.
