Can not configure transmitter

[tmcke]

When trying to use my transmitter, FMS2.06b is seeing the signal but I cannot configure the channels. When I load a model it automaticly begins at less than half throttle with out any surface control. Mysetup works ok in the DOS version.

Please help

Same problem...

Got MPX MC 3010

with 680 Ohm resistor

I've seen this problem before. After much investigation, user pulled out all his PCI cards. FMS then worked properly. Putting the cards back one at a time, he was able to find that his sound card was the culprit. No fix found yet. He have to leave out his sound card for now, using a silent FMS.

Check the BIOS settings on your computer. I had the same problem at first, found out that the bios allowed sharing of IRQ address between 2 devices. My bios setup allowed me to disable IRQ sharing, then the problem went away.

Good Luck

Thanks for the "fast" help...

I will try to change the irq of the par. port

good flight, good night *g*

Hi Folks

It still does not work !!!!

IRQ 7 is only used by the Par. Port...
Changed it to 5 in the Bios, still found signal but no controll.

In the FMS DOS running the test programm gives after 2 succesfull tests the error "timer fehler" or something like that
Probably this helps...

Will the serial interface override this problem ?

The "timer fehler" means, that the calculated and simulated time value isn't what the testprogram reads from the timer. The reason for this needs not to be a bad timer, because this check isn't coded very well, and above all under Windows not working always. Have you tested the program in plain DOS?

The problem is most certainly the IRQ. If the FMS does see the signal (this check is done without IRQ), but can't measure it, that problem could be the Interrupt.

Have you had a look at your Windows Device-Manager, wether there is another device using (or perhaps only blocking) this interrupt?

The serial port uses different IRQ, perhaps the problem would be solved this way.

Another reason for the problem could be a bad parallelport. There are said to be some ports, one which the interrupting doesn't work.

Hi Fans,
I figured out that not all parallel-port's work
by the same way!
on some Computers it works wiht 680R and a z-diode,
on others it needs a Transistor (pulld up by transm.)

Now I'm checking out, witch interface works on all different
typs of ports.

cheers and always happy landings,

Hi:
Having the same problem with my Gateway computer, Win98 and a Futaba T6XA transmitter.
FlyRC program works fine with the Tx.
I've studied the Interrupts and changed some settings, with no luck. Will try some more, but I will not take my computer apart like that other user did.

Do you have a Sounblaster Live card? I had the same problem until I disabled LPT interrupt sharing in SB 16 emulation driver. You find this setting in System Properties->Creative Miscellaneous Devices->Creative SB 16 emulation.

[Jeff D]

It works!!
Thanks, Ulf. Disabling the Soundblaster did the trick.
I was getting sick of that whiny noise anyway.

I have the same gliches ~ 20% at all channels.
Own a Hitec Prism 5x connected to 470 Ohm + Diode +Zener.
In Dos mode, without sound, RCS JRC and FlyrRC works fine.
But in Windows all thease + FMS glitches a lot.

Shoud disabling the sb 16 support in the Live correct the problem??

Thanks: Imi

if you just disabling the soundblaser 16 emulator you can found that some games or programs dont have any sound, but if you just disabling the parallelport irq sharing all will work like it should!!!
