C.8 Wiring Using Two Data Distribution Cabinets (Up to 24 dispensers)
Notes:
1. Two Current Loops are provided for communication to the dispensers from the HyperPIB.
Evenly distribute the dispenser loads across both loops in the Data Distribution Cabinets.
2. All unused dispenser positions in the Data Distribution Cabinets should be jumpered in
the cabinet with the switch placed in the “Auto” position. This practice reduces the overall
load on the loop.
3. Each loop in this configuration is limited to 12 dispensers and a total wire length of 1800
feet. This length of 1800 feet includes the distance between the HyperPIB and the Data
Distribution Cabinet, the distance between the first and second Data Distribution Cabinet,
and the distance between each dispenser and the Data Distribution Cabinets.
