For large systems, the distance between the transmitters and receiver may exceed the physical capabilities of a single controller. For these applications, multiple controllers can be used. The REMOTE1 and REMOTE2 provide the communications between controllers via two balanced
The AUX POWER IN allows for use of an external ±12 Vdc power supply to be used if the VXI mainframe can not supply the required power for a large switching system, or to compensate for local control cable losses, or special switch voltages. The AUX 1 and AUX 2 outputs can provide a
The
Switch control units can be individually addressed for independent control, or can share the same address for simultaneous switching or tree configurations. Each module has two bits of
