USB-TC User's Guide
Sensor Connections
All ground pins on the USB-TC (pins 9, 19, 28, 38) are isolated from earth ground. If a connection is
made to earth ground when using digital I/O and conductive thermocouples, the thermocouples are no
longer isolated. In this case, thermocouples must not be connected to any conductive surfaces that may be
referenced to earth ground
For general information regarding digital signal connections and digital I/O techniques, refer to the Guide
to Signal Connections (available on our web site at www.mccdaq.com/signals/signals.pdf).
