JetKVM ATX Board can't turn on my computer remotely

[ward-horsfall]

Hi,

I have got the JetKVM working successfully without the optional ATX board it works great. However, I have a problem getting the optional ATX board working with my HP ProDesk 600 G2 Small Form Factor PC.

When I connect everything together (JetKVM connected via miniHDMI, ethernet, RJ11, no USBC), the JetKVM powers up, connects to my network. I use the ATX Power Control browser extension, click the POWER button on the webpage, and nothing happens.

Am I correct in thinking that to get it to work at the simplest level, all I need to do is:

1. Connect the RJ11 cable between the JetKVM and the ATX board.
2. Supply power to the ATX board via USB-C instead of to the JetKVM (online instruction say it can power it this way, and indeed it did)
3. Connecting the ATX board BTN PWR+ and BTN PWR- pins to the corresponding motherboard pins (in my case the PB/LED header on my HP computer motherboard).

Thanks very much for any help,
Ward
