System Interface Connectors – MASTER and AUXILIARY

WARNING: The system interface connectors are for use with California Instruments

supplied cables, and only between California Instruments equipment.

A set of two System Interface connectors is located on the rear panel of each 4500CS chassis.

The system interface is used to connect the multiple 4500CS current sources in a

Master/Auxiliary configuration to create a 9000CS/2, 13500CS/3 or 18000CS/4 AC current

source configuration. In this configuration, only the Master power source has a built-in controller

and front panel. The System Interface cable provided in the CS Series ship kit (CI P/N 250778)

MUST be used to connect both chassis as shown in Figure 3-2.

Note that no user accessible signals are provided on the System Interface connections and they

should only be used for their intended purpose. To use the System Interface capability, the

output safety cover has to be removed. As such, multi-chassis configurations cannot be used

outside of a cabinet with proper rear screens.

Note that for multi-chassis systems, it is recommended to turn the Master unit ON first and then

the Auxiliary unit(s). To turn the system off, turn OFF the Auxiliary unit(s) first and then the

Master unit.

USB Interface

A standard USB Series B device connector is located on the rear panel for remote control. A

standard USB cable between the AC Source and a PC or USB Hub may be used.

Note: Use of the USB port to control more than one power source from a single PC is

not recommended, as communication may not be reliable. Use GPIB interface for

multiple power source control.
