General Bus Commands
General Bus Commands and Associated Statements
General commands are those commands, such as DCL, that have the same general meaning
regardless of the instrument. Table 4-3 lists the general bus commands along with the
programming statement for each command, which use the Keithley KPC-488.2 IEEE interface
and the HP- style Universal Language Driver. Note that the commands requiring that the primary
address be specified assume that the address is the factory-set address of 16.
REN (remote enable)
The remote enable command is sent to the Model 2010 by the controller to set up the
instrument for remote operation. Generally, the instrument should be placed in the remote mode
before you attempt to program it over the bus. Simply setting REN true does not actually place
the instrument in the remote state. You must address the instrument to listen after setting REN
true before it goes into remote.
Note that the instrument does not have to be in remote to be a talker.

PRINT #1, "remote 16" 'Place the Model 2010 in remote; turn
on REM annunciator
Note that all front panel controls except for LOCAL and POWER are inoperative while the
instrument is in remote. You can restore normal front panel operation by pressing the LOCAL
key.
IFC (interface clear)
The IFC command is sent by the controller to place the Model 2010 Multimeter in the local,
talker, listener idle states. The unit responds to the IFC command by canceling front panel TALK
or LSTN lights, if the instrument was previously placed in one of those states.
