Hi Bob, Yeah, I figured that retuning it would lose the 1PPS. No biggie. There are a number of those little connectors in this device, and the two that have cables connected use a flat 90 degree connector with a coax that's a bit smaller than RG-174. I just want to snap a pigtail on it and lead it out through a notch in the cover where the DB-9 connector is. There are several examples on the web where people solder wires to the connector and to the RS-232 header. I'd just as soon avoid soldering wires if I can.
