Are you using the stock module? If yes, you need to either:
- Take it out when using the simulator cable
- Leave it in, but change the protocol in your model setup to PPMsim, and turn
the radio on when using the simulator.

I normally use the PPMsim protocol. I get the same behavior if I remove the
module.
The bug is that the transmitter comes on when you plug in the trainer cord, and
the software is obviously running (I can go into config menus, etc.). However,
you don't get PPM output until you move the power switch to on. As far as I can
tell, the PPM output is the only thing *not* working. This is annoying, and
makes using the simulator painful.
The fix I would prefer is that you get PPM output without having to flip the
power switch, partly because I expect that can be done in software.
An alternative fix would be that the transmitter not turn on when you plug in
the trainer cord. I suspect this can't be done in software

No, backlight (depending on how it's installed) and the beeper are not powered
either. This is a hardware design issue.
The PPM signal not being present is also a hardware issue, when the module is
not powered it drags the signal down. This led to the "1k resistor mod" that
was recommended at some point.

Let's be clear here. I do not have the the resister mod, and I *am* using the
PPM setting on the transmitter. The Tx is *turned off*. The power switch is in
the off state.
When I plug in a trainer line, it powers on, *without* touching the power
switch. The backlight comes on. If the switches are in the wrong state, I get
beeps for warning. I also get beeps on button presses. The beeper is working
fine. The monitor changes as appropriate to changes in input controls. The only
thing that I doesn't appear to be working is the PPM signal. Turning on the
power switch causes the PPM signal to come on.
This behavior means that you have to remember to both turn off the power *and*
unplug the trainer cable in order to shut the power off. No other Tx I've used
does this - either it powers on completely when you plug in the trainer cable,
or it doesn't power on at all then.
I have been told that er9x does *not* suffer from this problem, which would
indicate that it's *not* a hardware issue. I'd intall er9x to test myself,
except my 9x build VM is running linux, which has fried itself.

I just tried T9X and TH9X cooperation in trainer mode (FW r2413 OpenTx) and
everything seems to be fine.

I also checked during the week-end in a public meeting. No problem here. Please
use the forum to ask questions, will be easier to answer. Unless there is a
real bug, which seems not the case here.

One last note: I have done the usual PPM circuit hw modification (inserted
resistance 1KOhm).
Almost certainly not a FW bug.

Ok understood, he doesn't have the 1k resistor mod. One possible fix would be
to force PPMsim when the Tx is slave (main switch OFF).

@mwm@mired.org
Did you try the PPMsim protocol with Tx OFF?

The usual procedure:
1. Master TX is on
2. Slave Tx off
3. Connecting cable
4. Slave Tx is automatically switched on and collaborates with Master Tx.
On both Tx's was selected protocol PPM 8Ch.
When using protocol PPMsim 8Ch slave must be turned on.

I actually did take this to the forums first (possibly rcgroups, not the
9xforums). I was told this was a bug in openTx, as er9x did not have it. It's
been a while, because I've moved (twice) while trying to find time to check the
er9x & openTx sources to see if I could find a fix and submit a patch.
Seems that ztrojanek sees the issues I have - that with PPMsim 8ch the slave
must be turned on to work, but comes on even if it's not turned on.
Yes, I've been using the PPMsim protocol.

As they say in some (not mentioned) company: This is not a bug, it is a
feature. :)
