Thanks for the info, I tracked down the manual for the z3801a and it seems helpful. Here are some pictures of the PSU and power connector area, if anyone has any insight into what voltage this thing is expecting. What's confusing to me is that the original marking, 20-72 V was crossed out, 48V written over the top, and then the DIPs internally being set to 24A. I'm not really sure what the A and B positions mean, either. Is the female DE9 on this wired so I can just plug a USB-Serial adapter into it directly, like a Trimble Thunderbolt, or do I need to make a null-modem cable?
