FMS and HeliSimRC problems (Tx does nothing)

[Mark _australia]

Very frustrated. Lots of questions.
I'm trying to use FMS and HeliSimRC on a PC running Win XP. Tx is the standard Spektrum one that came with my Blade CX2 (LP5DSM). Mode 1 Tx.
The interface cable is a USB that I bought on eBay, it came with FMS on disc so I assume the cable is FMS compatible.
Nothing works.

(1) When I plugged the Tx into USB the Tx was turned on, as soon as I plugged it in, it turned itself off (digital display died). Huh WTF?
Lucky I noticed the alkaline batteries were getting **** hot so I stopped!!!! Obviously the USB is powering the Tx and the non-rechargeable batteries don't like it.
Tested the Tx with the Blade CX2 and it still works thank god.
Plugged it in to USB with no batteries and nothing happens, no beeping, no red LED, no voltage display. So the USB is not powering the Tx??? WTF?

(2) regardless of what sim I use it won't calibrate or map or anything, it is as if the Tx is not connected. Well hardly surprising as the Tx is not behaving as if it is turned on. Is my cheapo Tx simply not compatible with any sim's?

(3) I have tried with and without the trainer switch engaged. I would think that is only for buddy box.... but do I need to hold the trainer switch all the time? (hope not!!)

Be nice if there was ANY info on the Tx in the CX2 manual. I know it is a basic unit but there is a trainer plug so the manual should at least cover it.

Now ascertained that the TX must be working even if the lights are off.... the computer recognises it and has PPM under game controllers. Unplug it and PPM disappears. Still can't get the sticks to move anything in the calibration of HeliSim or FMS. aaarrgghhhhh!!!!

You may be just seeing the USB dongle in windows. The rig will show as the usb interface and a controller of some kind. People who didn't know the tx had to be on would see the interface part but not the HID.

If you are plugging the thing in and the lights go out then something is bad wrong! Like it's shorting all the power from the TX. I don't know of anyone else that plugs in while turned on with either sim cable or buddy cable but I don't see what it could do.

When I had the LP5DSM, I used a 'stereo' mini headphone cable. The 'mono' headphone cable will short out the port. I didn't use the USB dongle, but instead straight to the mic with smartpropo and ppjoy. I had to plug in the 'stereo' headphone cable to the trainer port, and THEN turn the Tx on. Make sure your using a stereo end on the Tx. The port itself is JR compatible, but the plug needs the longer stereo end.
