Hello everyone!

I want to convert my IBM 1501485 XM Async Card to COM2.
Does anyone have the jumper settings for these cards?


Thanks in advance!

Just turn the smaller jumper-block to the right of U14 upside down. That should change it to COM2.

If you turn the other larger jumper block, the card will interface with curent-loop characteristics instead of RS-232C characteristics.
