GPIB Interface Problems
For proper operation the GPIB address of the FS700 must be set to
match that expected by the controlling computer. The default GPIB
address is 17, and it is a good idea to use this number in writing
programs. Any address in the range of 0 to 30 may be set in the
SETUP menu.
The FS700 will ignore its front panel when in the "REMOTE" state
(Remote Enable line asserted on GPIB interface). This state is
indicated by the front panel REM LED. To return to LOCAL operation
(i.e. to enable the front panel) press the FIELD key. Controlling
programs may inhibit the ability to return to LOCAL operation by
asserting Local-Lockout state (LLO).
The FS700 expects commands sent to it to be terminated by a linefeed
character or the "End or Identify" (EOI) message. Answers returned by
the FS700 are always terminated by a linefeed sent in conjunction with
EOI. Make sure that the controlling computer has been configured to
generate and accept these sequences.
