Chris, Are you suggesting reusing the entire cable? I wasn't suggesting that. The cable is over a meter long! Even if the wiring was correct, which it isn't, I don't know if you could pull enough power through those 28 guage wires even though they have multiple leads in parallel. Either remove the cable from the IDC connector and replace with something more appropriate or cut the cable and leave maybe 10 cm. of cable attached to the connector. Terminate as appropriate. Datum understood that different situations require different solutions. They provided both Molex and 'circuit board' connectors for maximum flexibility. Personally, I think the connector looks a little silly. It's so big compared to the X72. But for some users, it might be perfect. I'm looking forward to Mark's circuit boards. I have one of the official boards that I've barnacled a few extra leads onto to bring out the signals that Datum didn't, but it's ugly. A better solution would be welcome. You asked for the connector, I provided a source. As is typical with Time-Nuts equipment, some assembly is required.
