Please find attached the diagram, If you need anything changed let me know.


Thanks Stefan, could you:

remove "Jaycar P/N: " and just leave "XC4136" as that seems to be a common part number for that product.

change: "RS232 PCI Card using same connector as on about USB/RS485 Converter"

to: "RS232 PCI Card using same connector as the above USB/RS485 Converter"

and I will put in as is.

This looks good, and is very helpful! It may be prudent to show how the 5 pins on the terminal block shown correspond to the actual DB9 connector in the event that the 5 pin terminal block connector isnt available. I can only find 9 pin terminal block versions on Amazon. Although I believe your chart does have enough description to get you there.

Just a thought! Thanks again.


Just something I thought of. I am not sure if all of the RS232 cards have the same DB9 pins for the same signals. Maybe if someone can confirm that is a standard, I will map my DB9 connector and post the pinout. I just dont have a lot of time to research that at the moment.

The RS232 pins are standard although whether the pins for adapters are standard I have no idea.

Edit: Does this relate to yours opengear.zendesk.com/hc/en-us/articles/2...-DB-connector-pinout

Ok I will map the my connector pins tomorrow and modify the reference doc. I will just make a note that it is specifically for that connector.

Did you see the link in the previous post.

I don't think it is worth worrying about, so long as the pin function is known is should be no problem.

Ok, yeah I think the main thing is knowing the pinout on the plasma unit and if you create your own DB9 plug you would just need to map the correct signals together. The reference doc does show the mapping so most people should be able to figure it out.:)

Just had a look at that PDF and saw the PCI to serial card, i must have had over 30 of them! Most probably already thrown them as i have a strong aversion to anything RS232 from the days of 9.6K modems ! I took them out of some massive DVR's i installed in some shopping centers in two cities here.
Will check promptly if i have any left, and will do a giveaway if anyone needs them.

I made the comunication with an usb to rs485 from Icp-con 7561. It is working but i want to verify something. In material table i define a material with 45a and 128v. I start the process , everything if fine but in the voltage field in Plasmac i see only 60v. How can i verify where is the problem? I let the voltage divider on Powermax at 1:20, i made some test with a adjustable power source on the thc and seems to be fine...in this case if the voltage is not real in Plasmac, the thc is not working in real condition i think.
