User Signals
User Lines Connector
Auxiliary User Lines connector, located on the Ethernet/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 user lines connector signal requires that you provide external Vcc and ground. Use a standard 8-position telephone jack and data cable to connect to the user lines connector. To locate the connector, refer to the Ethernet/RS-232 Interface subplate drawing in Figure 2-2 on page 2–5. See Table 2-14for pin descriptions. The user lines connector outputs can sink a current of 5mA each. Figure 2-6 on page 2–27shows the portion of the option board schematic which contains the user line connector. Use the schematic as a reference when making input or output connections.
