• EOI (end or identify) is used by talkers to identify the end of a message.

Configuring the GPIB Controller

Refer to your GPIB interface documentation for details on how to set it up. These
settings are important:
Primary GPIB address:
Secondary GPIB address:
Timeout:
Serial poll timeout:
Terminate read on EOS:
Set EOI with EOS on writes:
Type of compare on EOS:
EOS byte:
Please note that overlooking these settings is a common cause of problems.

Changing Operation from Local to Remote

Sending a command over the GPIB bus addressed to the FPM-8200
automatically puts the instrument in REMOTE mode. In this mode the REMOTE
indicator is ON. When the instrument is in REMOTE mode, press LOCAL/ADR to
return to LOCAL (front panel) control.
If the REMOTE indicator is flashing ON/OFF, the controller has completely
disabled the front panel with a local lockout (LLO) command.
