Remote control is possible via the built-in analog or USB port or via one of the optional interface modules (Any-

Bus CompactCom, only with standard models of PSI 9000 2U series) or via the GPIB port (only with option 3W 

installed). Important here is that only the analog or one digital interface can be in control. It means that if, for ex-

ample, an attempt were to be made to switch to remote control via the digital interface whilst analog remote control 

is active (Pin Remote = LOW) the device would report an error via the digital interface. In the opposite direction, 

a switch-over via Pin Remote would be ignored. In both cases, however, status monitoring and reading of values 

are always possible.

Control locations are those locations from where the device is controlled. Essentially there are two: at the device 

(manual operation) and outside (remote control). The following locations are defined: 

Displayed location Description
-

If neither of the other locations is displayed then manual control is active and access from 

the analog and digital interfaces is allowed. This location is not explicitly displayed

Remote control via any interface is active

Remote control is locked, only manual operation is allowed.

Remote control may be allowed or inhibited using the setting 

Settings”“). In inhibited condition the status 

“Local” will be displayed top right. Activating the lock can be useful if  

the device is remotely controlled by software or some electronic device, but it is required to make adjustments at 

the device or deal with emergency, which would not be possible remotely.
Activating condition 

“Local” causes the following: 

•

If remote control via the digital interface is active (“

Remote”). then remote control is immediately terminated and 

must be reactivated at the PC once “

Local” is no longer active.

•

If remote control is via the analog interface is active (“

Remote”) then remote operation is only interrupted until 

remote control is allowed again, because pin “Remote” continues to signal “remote control = on”. Exception: if 

the level of pin “Remote” is changed to HIGH during the “

Local” phase.
