Remote Operation and Commands
Selecting and configuring an interface
Interfaces
The Model 6487 supports two built-in remote interfaces: GPIB interface and RS-232
interface. You can use only one interface at a time. At the factory, the GPIB is selected. To
select the interface, press COMM, select RS 232 or GPIB, then press ENTER. The Model
6487 will reset with the new interface selected.
GPIB interface
To configure the GPIB (IEEE-488) interface, press CONFIG then COMM when the GPIB
interface is selected, then select the primary address (0-30; default 22) and language
(SCPI, DDC, or 488.1). The primary address must be the same as that specified in the
computer program, but be sure to avoid address conflicts. Use the SCPI language setting
for most applications. See the Model 6487 Reference Manual for information on the DCC
and 488.1 programming languages.
RS-232 interface
To configure the RS-232 interface, press CONFIG then COMM when the RS-232 inter-
face is selected, then set baud rate, data bits, parity, terminator, and flow control. To assure
proper operation, be sure that interface parameters are the same as those used by the con-
trolling computer.
Connections
GPIB connections
With the power off, connect a shielded GPIB cable (Keithley Model 7007) between the
rear panel IEEE-488 connection (
) and the computer bus connector.
RS-232 connections
With the power off, connect the Model 6487 RS-232 connector (
) to the com-
puter serial port using a straight through shielded RS-232 cable terminated with DB-9
connectors (Keithley Model 7009).
Do not use a null modem cable
