170 Advanced Programming with the VT1529B  
Temperature Measurements
The VT1529B adds the capability to measure E, J, and T type thermocouples 
in addition to strain (other thermocouple types are not supported with the 
new functionality). Either the VT1586A Rack-Mount Terminal Panel or a 
user provided isothermal panel can be used. For this discussion, assume that 
the VT1586A and the VT1529B option 002 VT1586A-to-VT1529B cable 
are being used.
Note
If thermocouple types other than E, J, or T need to be used, they must be 
configured for dc voltage measurements and their compensation routines 
must be provided.
Connecting the
VT1586A to the
VT1529B
To use the VT1586A with the VT1529B, the VT1529B option 002 
VT1586A-to-VT1529B cable should be used. This cable provides 
connections for up to sixteen channels of temperature measurements 
(therefore, two cables are required for the 32 channels on a VT1586A).
Note
For each VT1586A used with the VT1529B, two channels for the reference 
thermistor measurement must be dedicated. This leaves thirty channels for 
thermocouple measurements, unless the VT1586A is in a temperature- 
controlled environment and SENS:REF:TEMP:POST is used to specify the 
reference temperature for the EU conversion routines.
On one end of the cable, there is a SCSI connector that plugs into one of the 
two SCSI jacks on the back of the VT1586A. On the other end, there are 
sixteen RJ-45 jacks that plug into the front of VT1529B. The RJ-45 jacks are 
numbered to make the interconnection easy. Figure 5-2 and Figure 5-3 show 
how to make the connections.
