Installation and Configuration
IEEE-488 Controller Connection
Release 1.2
23
To return to remote mode, ensure that the REN line is asserted and then send any
valid GPIB or device-dependent command.
Local Mode
Operation
In local mode operation, the voltage and current output levels and the OVP trip
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:
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
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
Selection
Over voltage protection (OVP) on the GPIB interface is set at the factory for
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
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.
!
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.
