Quote from: tkellogg on February 25, 2025, 04:25:10 AMI am working on the interior of my 737 and I noticed a module/panel on the sides of the cockpit. I believe they were done away with in the 700 and 800 versions of the 737. Anyone know what these are? If anyone has a picture I would appreciate you sending a picture with your response. Thank you

Identification

The component in your image appears to be the:
Captain's Nose Wheel Steering Tiller Panel (also called the Ground Steering Control Unit).

Function

It allows manual control of the nose wheel for taxiing on the ground.

The tiller handle (the gray lever with a blue stripe you see) is turned left or right to steer the nose wheel.

It provides fine directional control while taxiing, something the rudder pedals can't do accurately at low speeds.

Location

On 737-100/200/300/400/500 (Classics): mounted on the sidewall console just left of the captain's seat, beside the armrest.

On later 737NG (700/800/900) and MAX, Boeing redesigned and streamlined this area — the tiller was reshaped and integrated into a smoother side panel.

or i may be wrong as jackpilot say picture is blur

Hello everyone,

I'm working on building a 737NG-style flight deck for a personal simulator project. I'm not looking for any proprietary Boeing data — just general dimensions, reference measurements, or CAD models that can help me get the panels and structure scaled correctly.

I'm starting with my own CAD in Fusion 360 and plan to fabricate locally with CNC aluminum and acrylic once I verify the fit. If anyone has shared measurement sets, DXF outlines, or recommendations for accurate reference sources, I'd greatly appreciate some guidance or pointers.

Thank you in advance for any help or advice — this community has been an incredible resource for builders.

Jason is correct, the USB port can only sustain a very small ammount of current. In fact connecting too many devices to a USB port can damage it permanently.

The point being that power supplies are so cheap these days it's not worth the risk.

Yes, you need to supply power, the 5v over the USB is not enough.

Hi all,

I recently bought someone's old A320 cockpit project. It was a bit of a mess, but I now have inputs responding in the SIOC software, and LED's switching on and off. However the 7-segment display it rather dead.

The 7-segment displays are connected to an IOCard Display, which is connected to a Master card, which is then connected to the USB Expansion card.

My question is, does the Master card need to be supplied by a separate 5v power supply to the two 5v pins? I presume the USB's 5v might not be enough to drive everything.

Hoping someone might now as this hardware is quite old now.

Thanks,
Rob

Welcome to the group Andre. 

Looking forward to seeing more of your product development and project updates.

Interesting product.  

Do you have some photos to post? I would be interested in hearing more about this. 

Thanks

Hiya Jack,

Yes still around, writing for the mag and selling a few bits on eBay.
Surprising where it all goes!!!

Hope you're well my friend.

Joe.

Hi Joe
Glad to see you still kicking 

We are running Prosim 737 (last version supporting Revsim TQ) with MSFS 2020 and Windows 11. We have tried to recalibrate our Revsim TQ using calibration software version 1.7. but get the error "HID not detected" (also tried using Windows 7 with same result). I read on your forum that a user back in 2017 was able to successfully recalibrate using version 2.2.05 under Windows 10. The TQ appears to be a plug and play version and not using SIOC.

If anyone is able to send me a copy of version 2.2.05 it would be very much appreciated.

Thankyou
