Appendix
Auxiliary LHe Level/Temperature Connectors
Note
For maximum noise immunity, use shielded cabling and connect
one end of the shield to the Magnet Station Connector shell.
The connectors provide an interface for connecting a single integrated
instrumentation cable from the magnet support stand to the Model 430
Programmer. The Model 430 Programmer can then be used to distribute
the signals to the appropriate instruments or data acquisition systems.
The LHe level and temperature sensor signals are also internally routed to
the LHe Level / Temp Connectors.
If the Model 430 Programmer is purchased as part of a magnet system, a
Magnet Station Connector instrumentation cable will be provided with the
system.
A.2 LHe Level / Temp Connectors
The two 9-pin D-sub male LHe Level / Temp Connectors are identically
wired and connected pin-for-pin internally.
