3.7 Connectors - Rear Panel
A number of connectors are located along the top rear covers. These connectors are in a
recessed area to protect them from shipment damage.
3.7.1 System Interface
WARNING: The system interface connectors are for use with AMETEK supplied
cables, and only between California Instruments equipment.
The Clock and Lock BNC connectors located on the rear panel are used to synchronize and
control the phase shift between the three outputs when 3 units are operating as a three-phase
clock and lock system. This mode of operation requires the -LKM (on Master unit) and -LKS (on
Auxiliary units) options. See paragraph 3.10 for more information on this mode of operation.
A set of two identical System Interface connectors, P8 and P9 is located on the rear panel of
each MX15 chassis. The system interface is used to connect the multiple MX15 power sources
in a Master/Auxiliary configuration to create MX30/2 or MX45/3 models. In these configurations,
only the Master MX15 power source has a built-in controller and front panel.
The same connector is also used to control the optional OMNI-3-75 Reference Impedance.
