Remote Operation
Selecting and configuring an interface
Interfaces
Model 6514 supports two built-in remote interfaces:
•
GPIB interface
•
RS-232 interface
You can use only one interface at a time. At the factory, the GPIB bus is selected. You can
select the interface only from the front panel. The interface selection is stored in non-volatile
memory; it does not change when power has been off or after a remote interface reset.
GPIB interface
— The GPIB is the IEEE-488 interface. Model 6514 must be assigned to
unique address. At the factory the address is set to 14, but can be set to any value from 0 to 30.
However, the address must not conflict with the address assigned to other instruments in the sys-
tem. You can use either the SCPI or DDC language to program the instrument.
RS-232 interface
— When using the RS-232 interface, you must set baud rate, data bits, par-
ity, terminator and flow control. For the RS-232 interface, you can only use the SCPI language
to program the instrument.
Languages
For the GPIB interface, there are two programming languages to choose from:
•
SCPI language
•
DDC language
NOTE
For the RS-232 interface, only the SCPI language can be used to program the instru-
ment. When the RS-232 interface is selected, it automatically defaults to SCPI.
SCPI language
— Standard Commands for Programmable Instrument (SCPI) is fully
supported by the GPIB and RS-232 interfaces. Always calibrate Model 6514 using the SCPI
language.
DDC language
— Model 6514 implements most DDCs (device-dependent commands)
available in the Keithley Models 6512, 617, and 617 HIQ electrometers. The commands are pro-
vided in Appendix D. See the appropriate instruction manual for details on operation.
Interface selection and configuration procedures
When you select (enable) the GPIB interface, the RS-232 interface disables. Conversely,
selecting (enabling) the RS-232 interface disables the GPIB interface.
