The pins are normally pressed into the connector. If you can open it, you can usually pull them out. That way you can test non-destructively.

OM2500A only uses RxD, TxD. It does not assert any other lines. RTS & DTR are wired straight through, I haven't checked DSR & CTS for continuity.

I can stop posting *correct* information about this amplifier at any time, since it appears to be ignored. I thought it would be useful since I actually *own* this amp and use it with a K3 and computer. Apparently not!

I would suggest that you not break off the pins unless you have a cable with formed and sealed backshells. If you can open the backshell, just cut the wires on the 'backside' of the connector.
