3.8.1 System Interface
WARNING!
The system interface connectors are for use with California Instruments supplied cables,
and only between California Instruments equipment.
A set of two identical System Interface connectors are located on the rear panel of each Sequoia/Tahoe
unit chassis. The system interface can be used to connect the multiple Sequoia/Tahoe power sources in
a Leader/Follower configuration.
The Leader connector and Follower connector are used to connect Follower/Auxiliary power sources to
the Leader power source for operation in parallel, multi-chassis systems; refer to Figure 3-13 for the view
of connectors, with Table 3-12 and Table 3-13 for descriptions. The Leader/Follower interface signals are
dedicated to the control of the parallel-group operation and are not to be utilized by the user.
The power source that is to be the Leader will have the System Interface cable plugged into its connector
labeled SYSTEM INTERFACE TO FOLLOWER - 1. The other end of the System Interface cable will plug
into the connector labeled SYSTEM INTERFACE TO LEADER in the first Follower power source
comprising the system. Additional Follower power sources would be chained together with System
Interface cables connecting the Follower connector of one unit to the Leader connector of the next unit in
the chain. Refer to Figure 3-18 for an example of a parallel system.
