E-2
E Interface Operation RS-232 and IEEE-488 / GPIB
RENDCL Sets the status REMOTE and loads the following initialization settings:
DCL Loads the initialization settings (see above) without changing the current REM
status i.e. the respective status LOCAL, REMOTE or LLO is maintained.
IFC Loads the initialization settings and sets the status LOCAL. The command
corresponds to DCL
+
GTL.
E.2.2 Control Commands IEEE-488 / GPIB
The controller recognizes three different operating modes for remote control
via the interface IEEE-488 / GPIB:
LOCAL The vibrometer is controlled via the display and the keys on the front of the
controller.
REMOTE The vibrometer can be controlled via the front panel and via the interface. The
status REMOTE is set when an IEEE-488 / GPIB bus controller asserts the
signal REN and addresses the controller.
LLO = LOCAL LOCK OUT. The status LLO can only be set from the status
REMOTE. In this mode, it is only possible to operate via the interface
IEEE-488 / GPIB. Key input on the front panel is ignored, only the key RESET
retains its function.
The operating mode of the controller is shown on the front panel with the L
ED
s
REMOTE and LLO as follows:
E.2.3 Echo Commands
ECHOON As default, the echo function is switched off when the system is being
controlled remotely. With this command an echo is returned for valid
commands.
ECHOOFF The echo function is switched off. An answer is only returned on the
corresponding commands.
