SCXI-1121 output multiplexer. This is the factory setting. The DTEMP
position of jumper W1 (jumper W5 on the SCXI-1321) connects the
temperature sensor to the SCXI-1121 MCH4+ signal on the rear signal
connector.
In both MTS and DTS modes, the reference to the temperature sensor
signal is the SCXI-1121 analog ground that is connected to MCH0– in the
MTS mode and to MCH4– in the DTS mode. Notice that MCH4– is
continuously connected to the SCXI-1121 ground, whereas MCH0– is
switched through the output multiplexer.
One jumper block comprises both positions; therefore, you can use only
one type of configuration at a time. The parking position for the jumper
block is in the MTEMP position (the temperature sensor is disabled until
the RTEMP bit in the Configuration Register selects the sensor).
Tables 2-13, 2-14, and 2-15 show the jumper settings on the SCXI-1320,
SCXI-1328, and SCXI-1321 terminal blocks.
