Piggybacking off of this, does anyone have the proper pinouts for the Varian
VT connector?
A graduate student decided that he could fix our Varian VT connector and
proceeded to replace the DB 9. He claims to have followed the pinouts of
the original connector, but we don't have proper connections now.

Hi Casey,
Those DB 9 connectors have always been problematic. I've found the best
solution, (given that you use the same interconnect) is to use a high a
quality connector( they are not all created equal), with a lot of back
support, because the thermocouple wires are very stiff and brittle. Those
are the two main issues; poor contacts in the connector housing, and
breaking the wires off with too much flexing, which happens with frequent
probe changes.
Regards, John \\\

Hey all! I wanted to check with the spinlanders before trying to re-invent
the wheel. Has anyone developed a replacement connect for the Varian VT
serial connector? I'm running both a VNMRS and a INOVA consoles and looking
for a more reliable connection for the VT sensor.
