Chapter 4
Remote Operation
Introduction
This chapter describes methods for operating the Calibrator by remote control.
Remote control can be interactive, with the user controlling each step from a
terminal, or under the control of a computer program running the Calibrator in an
automated system. The Calibrator rear panel has two ports for remote operations:
• RS-232 serial port
• IEEE-488 parallel port (General Purpose Interface Bus or GPIB port)
RS-232 The serial port connects the PC and Calibrator. You can write your own
computer programs using the command set, or operate the PC as a terminal and
enter individual commands, or you can purchase optional Fluke MET/CAL
software for RS-232 system operations. Typical RS-232 remote configurations are
shown in Figure 4-2.
IEEE-488 The IEEE-488 parallel port is usually used in larger control and
calibration systems. An IEEE-488 system has the ability to serve multiple
Calibrators and multiple UUTs. Also, parallel system throughput is faster than
serial system throughput. The controller in an IEEE-488 system is typically a
Windows

compatible personal computer (PC) equipped with one or more IEEE-
488 ports. You can write your own computer programs for system operation using
the command set, or you can purchase optional Fluke calibration software
MET/CAL. Typical IEEE-488 configurations are shown in Figure 4-3. The
configuration showing the PC with two IEEE-488 ports is used with MET/CAL,
which prefers UUTs on a separate IEEE-488 port. You can also “piggy-back” the
connectors on a single IEEE-488 port.
After configuring the IEEE-488 or RS-232 port for remote operation, you are
ready to begin using the command set. The operation of the command set is
described under “Using Commands” in this chapter. A summary of remote
commands is in Chapter 5, “Remote Commands.”
