4.2.1 Rear Panel SW1 Switch (continued)
The rear panel SW1 switch is marked with the word OPEN on its upper surface. Any of the eight switches on
SW1 is OFF when it has been flipped up to break contact, ON when flipped down to close contact. Table 4.2-1
shows the functions assigned to each SW1 switch.

Resetting the Switches
Before making any changes to the switch settings, disable the power supply output by pushing the front panel
STANDBY switch to its IN position. This shuts down the power supply on a temporary basis. The front panel
S/D LED turns on. Then use any small, flat-bladed screwdriver to change the switch settings.
4.2.2 Rear Panel J2 Connector
The J2 Programming and Monitoring connector is a 15-terminal wire clamp connector located on the power
supply's rear panel. See Figure 4.2-2. The J2 connector provides access to the following functions:
N
Remote programming of output voltage AND/OR current limit
N
Remote monitoring of calibrated readback signals for output voltage and output current
N
Remote control of the shutdown function using TTL-compatible signals
