The EX1200-TBR chassis is a 1U receiver capable of housing six terminal blocks. The
EX1200-TBR ships with rubber feet for table top installations, but may be fitted with rackmount
ears for installation into a test rack (P/N: 70-0367-010).
To install a terminal block into the EX1200-TBR, insert the flanges on the side of the terminal
block into the guide rails of the desired slot. Continue to push the terminal block into the receiver
until it is sMUXred by the rear-locking latch of the receiver. To remove the terminal block from
the EX1200-TBR, hold the center thumbscrew on the terminal block, then pull the terminal block
from the receiver.

ROGRAMMING

VERVIEW
To measure the thermistor temperature, first ensure that the P2 jumper has been configured
properly (see
328H
Jumper Configuration
for more detail). Next, a scan list is developed which scans
CH1_1. In the following programming overview, a method for taking measurements using the on-
board thermistor will be provided.
Two scenarios will be provided: one where only the thermistor temperature is measured and one
where the RT1 is used as a reference junction and other channels make temperature
measurements. In the first example, the user can only measure the thermistor temperature at
CH1_1. In the second example, the user can measure the thermistor temperature at CH1_1 and can
also measure temperature on another channel which uses the CH1_1 as a reference junction.
Note that, in these examples, it is assumed that the EX1200 DMM is being used and that the P2
jumper has been configured appropriately.
Measure Thermistor Temperature
Either the VTEXScanner driver or the scanner soft front panel can be used to perform this
sequence.
1)
Set the DMM to measure temperature using the thermistor.
a. Set the DMM function to
Temperature
.
b. Set the transducer type to
Thermistor
.
c. Set the thermistor resistance to
10000
(the thermistor is 10 kΩ).
