[dsg-hdice] USB to RS-232 converter

[Brian Eng]

The sensor cables are probably not labeled as well as they could be.

Someone wrote 1 and 2 on the connector but they actually should get plugged into ports 2 & 3. I moved the serial port back to the adapter so that way port 1 would be used.

Also the LHe level sensor was unplugged from the back of the sensor box so I plugged that back in.



What's wrong with the FRS program?
