Darrell,
I just bought that exact unit a couple weeks ago, probably from the
same seller. It works directly with an RS-232 port. I'm using mine
with a RS-232/USB adapter to my laptop. The power supply board only
supplies the +/- 12VDC and + 5VDC.
Here are the Mouser part numbers for the power

Most RS-232 level shifters also include an inverter.
I'd just plug it in and see if it wor
