Installation and Configuration

IEEE-488 Controller Connection

To return to remote mode, ensure that the REN line is asserted and then send any valid GPIB or device-dependent command.

Local Mode In local mode operation, the voltage and current output levels and the OVP trip Operation level are set with controls located on the front panel. Refer to the operating manual

for a description of the functions available at the front panel.

While in local mode operation, you can change power supply control to remote mode by ensuring that the GPIB REN line is asserted and then sending any software command to get into remote mode and the OUT ON command to restore the output. You can return to local mode by sending the GPIB GTL command or negate the REN line.

Example:

 

ibfind "devname"

Address the unit (devname or device name as

 

configured originally with ibconf).

ibloc

Set unit to local mode.

ibwrt"id?"

Any message to the unit now puts it back to

 

remote mode.

ibloc

Toggle back to local mode.

IEEE-488 Controller Connection

Use an approved IEEE-488 connector and cable when connecting the power supply’s GPIB interface to your IEEE-488 GPIB network. The IEEE-488 connector uses mating connector J8 on the rear panel of the power supply.

Internal PCB Jumper Selections

CAUTION

If you remove the unit's cover, use proper static control techniques to avoid damage to static-sensitive components on the printed circuit board.

You can select how you use OVP (over voltage protection) control and TTL shutdown by changing jumper positions on the GPIB PCB. Refer to the operating manual for information on how to use over voltage protection and TTL shutdown.

OVP Over voltage protection (OVP) on the GPIB interface is set at the factory for Selection remote software operation. When operating the power supply in remote mode, you

control the OVP trip level using the OVSET software command. If you return the power supply to local operation by using the GPIB software commands or the by
