4.4 Remote Programming

Remote programming is possible for the output voltage, current, and OVP. Either
external voltage sources or resistances can be used to program the output parameters
from zero to full scale. The programming methods can be used in any combination.
Also, the programmed values are totally independent of those set with the front panel
controls. The front panel V/I and OVP PREVIEW switches remain functional during
remote control, allowing verification of the programmed settings.

A front panel LOCAL/REMOTE switch (momentary action) allows toggling between
front–panel and remote control. The REM indicator will be on when remote control is
enabled. This allows stepping between two parameter values, or could be used to
facilitate troubleshooting the remote interface. However, the unit will always power–up
in remote control if the remote interface is enabled.

The LOCAL–LOCKOUT digital control signal can be used to disable the toggling
function, and keep the power supply in remote control. This is advantageous in
applications where operator adjustment of the output parameters is not desired.
