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 program-
ming 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 ad-
dress 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 2000 by the controller to set up the instru-
ment for remote operation. Generally, the instrument should be placed in the remote mode be-
fore 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 need not be in remote to be a talker.

Note that all front panels 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.
