Geekdesk Support #7

Open J-Camping opened 1 year ago

J-Camping commented 1 year ago

Hello! I recently received the Upsy desky and would like to try it out on my geekdesk. It looks like pin 3 has 5v and pins 1,5,7,8 all appear to be grounds.

The controller is labelled ey-h6032c, and does also have an rj11 port. I found this manufacturer page, but it didn't seem to have much information. https://www.eyoungonline.com/products/pro_51.html

Guessing at a minimum I would need to make a custom cat 5 cable to swap the 5v and gnd to match the upsy desky?

Want check with you before breaking anything too badly. Edit: adding some photos of the main controller board, let me know if photos of the remote controller would also help.

Thanks, James

Hi! Yes, at minimum you would need to make the +5V and GND match the pinout on the Upsy Desky. The pinout is available here.

I would also make sure that the control box uses a 5V logic level but considering it has a 5V rail, it probably does.

After that I would go ahead and try out the stock firmware and see if any of the existing protocol decoders work. If not, then more reverse engineering work is probably required.

Pictures of the handset PCB may be helpful since the pads have usually been well-labeled on them for other models.

I reversed the wires for 5v and gnd, the board powers up and I can connect to the web interface. As soon as it turns on, the board goes to its highest or lowest level. I haven't moved any other wires yet.

When either uplift or jarvis is selected and I select preset 1 it goes to the bottom, preset 2 doesn't do anything, preset 3 goes to bottom, preset goes to 4, and the slider doesn't do anything.

Let me know what I can do to help with any reverse engineering, and thank you for creating this and the help!

I wanted to record a few things I worked out:

Pinout from my EY-H6032C control panel cable matched up with your image (JCH35-TLD-V3)

  1. White - PTC1
  2. Yellow - PTC2
  3. Red - VCC = +5V
  4. Green - PTB5
  5. Black - GND
  6. Blue - PTB6
  7. Manual up - not connected on cable - see [1]
  8. Manual down - not connected on cable - see [1]

Notes:

  1. Jumping 3 to 7 or 8 causes the desk to go up and down. This matches with https://github.com/Hypnopompia/photon-desk/blob/master/README.md
  2. Also see https://forums.adafruit.com/viewtopic.php?p=649290, though the underlining control panel processor seems slightly different (JCH35-TLD-V2)
  3. Appears that Jiecang has slightly different wirings between the Geek Desk and other desks.
