SynGuider 1 firmware update cables PIN outs?

[Stu_53N_002W]

I have a Sky-Watcher SynGuider version 1 with Ver 1.1 firmware and want to update but don't have the required cable kit. The PC serial cable and shorting plug.

edit: Ver1.1 is actually the last available update for the early version of SynGuider. That is, the one without USB and having a Sony sensor. So I do have the latest firmware.

Any one know the wiring for each?

 

VER. 1.1 is the last available firmware for the SynGuider none USB version.

Good news.

The PC communication cable PIN outs maybe found at https://www.nexstarsite.com/PCControl.htm

Note that the PC connection is a 4PxC plug, possibly the Hand Control RS-232 Port Cable link.

I've actually purchased an FTDI version for serial emulation via USB.

As for the short plug. I asked a very gracious eBay seller for a picture which they sent. PIN's 1 and 8 are short, so I've made one.

 

I better mention, the image above is a photo of my phone screen with the ebay image. On the screen, to the right, I've placed my home made short plug. Hence the different sizes.
