PFC Jetliner Yoke and Digital Throttle Quadrant Unresponsive

[CraigM]

Hello

I have been using a Jetliner Yoke and Digital Throttle Quadrant (2 engine Jet) for a few months now. I have been having an intermittent problem over that period of time...loss of Yoke and Quadrant control - usually an hour or so into a flight. Often, the control is not entirely lost but hugely delayed, by maybe a minute or more. i.e., turn yoke, and nothing happens in the sim for a minute or more, same is true for the throttles, flaps etc. Other times complete loss occurs.

Some other info:

FS2004 patched

Serial to USB adapter from PFC

Project Magenta Boeing Suite running on 3 Computers

FDS Flight Center 737NG

2 Engine Jet Throttle Quadrant

Jetliner Yoke connected to Quadrant

CH Pro Peddles USB connected to FS2004 machine's USB port

My PM setup has been running properly for about 2 years...this problem first appeared after installing the PFC gear.

It would seem the PFC USB port is turning off, or going into some sort of sleep mode. I have added AutoRestartTime to my PFC ini...what do the numbers mean...your docs suggest =3000??

Are there any situations where the CH USB Peddles may be interfering with the PFC driver?

Any further ideas would be much appreciated.

Thanks.

What version of my PFC.DLL? If not the latest interim, please try that (above).

Sounds very much like Windows power management. Go into the properties for the USB port and switch it off.

Also, try putting your two USB devices on separate USB hubs -- the motherboard USB ports are in pairs. Try moving one of the devices to a different pair.

Doesn't it say? 3000 milliseconds in 3 seconds.

Welcome back Pete

Thanks for the leads...I'll investigate them this evening.

I'm using the latest PFC driver, 1.998 I believe.

Hi Pete

Tried the suggestions.

>>>What version of my PFC.DLL? If not the latest interim, please try that (above)....1.998

Still getting interference of some kind when the CH Pedals are connected. This evening, I got greatly delayed PFC inputs with the pedals connected, and random uncommanded inputs (flaps, spoilers)...not immediatly, but after about 5 minutes of flight.

This is the earliest I've seen this behavior. I had previously completed 3 or 4 flights with the PFC gear alone (pedals disconnected - physically) and no issues. It really seems something just doesn't like those pedals!!

Have you encountered or heard of conflicts between CH stuff and PFC stuff?

I guess I'll have to order those $595 PFC pedals!!! :>)

No, sorry, that's pretty weird. Are you using a CH driver for the pedals, or one found for you by Windows?

It has got to be some sort of USB level interaction -- but why it was ever delayed like that in the first place baffles me. That's definitely usually down to USB power management problems. In fact if they interfere with each other then any delay in that is odd anyway. Something hardware-wise is changing, voltage is going down or temperature up.

There is another thing to try -- see if you can find another USB - Serial driver for the PFC. The original one I had was problematic in WinXP, I think it was old and designed for Win98. Try http://www.ftdichip.com/ -- most of the seerial adapters use FTDI chips I think.
