Configuring the Temperature Sensor
To enable you to use thermocouples with SCXI modules, the TBX-1303
has a thermistor temperature sensor for CJC.
You can connect the temperature sensor to an SCXI module in one of
two ways:
•
Multiplexed temperature sensor (MTEMP) mode—set the TBX-1303
terminal block switch S1 to the MTEMP position. This setting is the
factory default. Refer to Figure 4 for the location of switch S1.
•
Direct temperature sensor (DTEMP) mode—set the TBX-1303
terminal block switch S1 to the DTEMP position. This mode connects
the temperature sensor to a separate DAQ channel through the SCXI
module. Refer to the SCXI module user manual to configure the SCXI
module for DTEMP mode.
