• IFC (Interface Clear)
Cancels (unaddresses) talker and listener.
• REN (Remote Enable)
Transfers the instrument from local control to remote control.
• GTL (Go To Local)
Transfers the instrument from remote control to local control.
• SDC (Selective Device Clear), DCL (Device Clear)
Clears the GP-IB input/output buffer and resets after an error. The setup
information and measurement state are not affected.
DCL applies to all devices on the bus, while DSC applies only to designated
devices.
• GET (Group Execute Trigger)
Updates the displayed data during sample hold.
• LLO (Local Lockout)
Invalidates the ENTER/LOCAL on the front panel, preventing an inadvertent
switch from remote control to local control.
REMOTE is displayed on the screen when the instrument is in remote mode.
No front panel keys except the ENTER/LOCAL can be operated.
To cancel remote mode, press the ENTER/LOCAL. REMOTE will disappear
from the screen, indicating that the instrument is now in local mode. However,
this is not possible if Local Lockout has been set.
The following operation modes are available for the GP-IB interface provided
with the instrument.
Addressable Mode
In this mode, the instrument is controlled by commands issued from the
controller. When the OD command (measured or computed data output request
command) is received, the instrument outputs the measured or computed data.
Talk-Only Mode
This mode does not require a controller.
Measured or computed data is output at the display update intervals. This
mode is useful when the instrument is connected to a listener-only device such
as a printer.
A particular address is assigned to each device connected to the GP-IB interface
so that every device can be recognized by every other device. Therefore, an
address must be assigned to this instrument when it is connected to a personal
computer.
If this instrument is to be used with a listen-only device, it must be set to talk-
only mode.
