How to Change between Remote and Local Operation
In addition to local mode (front panel operation) and remote, the Calibrator can be placed
in a local lockout condition at any time by command of the controller. Combined, the
local, remote, and lockout conditions yield four possible operating states described as
follows.
Local State
The Calibrator responds to local and remote commands. This is normal front panel
operation. All remote commands are allowed to execute.
Local with Lockout State
Local with lockout is identical to local, except the Calibrator will go into the remote with
lockout state instead of the remote state when it receives a remote command.
Remote State
When the Calibrator is placed in remote, either via RS-232 REMOTE command, or via
IEEE-488 asserting the REN line, it enters the remote state. In the remote state, the
Output Display continues to display the output setting or measurement as in local
operation. The Control Display changes to:
5-20
<ibwrt "uut_sendb 82,69,77,83,11,13">
the UUT serial port. After the command is entered, the Win32 Interactive Control
shows the status of the command. If an error is encountered, check the typing or
consult the National Instruments manual regarding Win32 Interactive control. The
count message is the amount of characters sent over the bus.
