TTL You can use the Shutdown function to disable or enable the supply's output. Shutdown Disabling the supply using TTL shutdown allows you to make adjustments to the

load or to the power supply without shutting down the power supply. With the GPIB interface installed, TTL shutdown is activated by a TTL signal to Pin 1 of the J7 connector on the interface subplate. The shutdown user line uses a 0-5Vdc TTL input with a high signal range of 2.2-5.0Vdc. The current range of the shutdown line is 1-10mA. See Figure 2.5, “J7 User Signal Connector Circuit Block Diagram” on page 31 for a schematic of the J7 connector containing the shutdown user line.

You can select the logic level of the TTL input by changing the J93 connector on the GPIB PCB. Table 2.7 shows the TTL signal levels for the J93 jumper settings. See Figure 2.2-3 for the location of the J93 jumper on the printed circuit board.
