User Signals
Auxiliary connector J7, located on the RS-232 interface rear panel, provides
several signals to increase your operating control of the supply. These signals are
dependent on the operator's design and uses. The operation of the J7 signal requires
that you provide external Vcc and ground. Use a standard 8-position RJ45
connector and data cable to connect to J7. To locate the connector, refer to the
RS-232 interface subplate drawing in Figure 2.2, on page 16. See Figure 2.5 for pin
descriptions. The J7 outputs can sink a current of 5mA each. Figure 2.6, on page
32 shows the portion of the option board schematic which contains the J7
connector. Use the schematic as a reference when making input or output
connections.
