Remote / Local Key
This key has a double function, depending on the state of the power supply
(remote mode or local mode).
Local Mode Function
While in local mode of operation, Remote / Local key has a double function,
depending on the state of the power supply.
If the power supply is in calibrating mode, Remote / Local key is used to leave
the calibrating mode and return to normal mode of operation (for more
information, please refer to Calibration Overview section)
If the power supply is in limit mode or normal mode of operation, by pressing
Remote / Local key, available interfaces are displayed.
Remote Interface Configuration
Available interfaces for 912x power-supply models:
9120 9121 9122 9123
RS-232 Standard Standard Standard Standard
GPIB / 488 Optional Optional Optional Standard
If a power supply has both interfaces implemented, only one interface can be
enabled at a time.
Interface selection (and coresponding parameters) is kept in a non-volatile
memory, so when powered on, the last selected interface is active.
For a power supply that has both interfaces implemented, when delivered GPIB
/ 488 interface is selected.
The remote interface can be selected by using front panel or by using a
command sent over the interface. Here is described remote interface selection
using front panel keys.
If the power supply is in local mode of operation, by pressing Remote / Local
key, selected interface is displayed (RS-232 or GPIB / 488).
