Remote Operation (RS-232)
There are two rear-panel serial data RS-232 ports: SERIAL 1 FROM HOST, and
SERIAL 2 TO UUT (see Figure 2). Each port is dedicated to serial-data communications
to operate and control the Product during calibration procedures. For complete
information on remote operation, see Chapter 5 of the Operators Manual.
The SERIAL 1 FROM HOST serial data port connects a host terminal or personal
computer (PC) to the Calibrator. To send commands to the Calibrator: enter commands
from a terminal (or a PC running a terminal program), write your own procedures with
BASIC, or use optional Windows-based software such as MET/CAL Plus.
The SERIAL 2 TO UUT serial data port connects a UUT to a PC or terminal with the
5502A (see Figure 2). This “pass-through” configuration removes the requirement for two
COM ports at the PC or terminal. A set of four commands control the operation of the
SERIAL 2 TO UUT serial port. See Chapter 6 for a discussion of the UUT_ commands.

Remote Operation (IEEE-488)
The rear-panel IEEE-488 port is a fully programmable parallel interface bus that
complies with standard IEEE-488.1 and supplemental standard IEEE-488.2. When the
Calibrator is used by remote control of an instrument controller, the Calibrator operates
exclusively as a “talker/listener.” You can write your own programs with the IEEE-488
command set or run the optional Windows-based MET/CAL Plus software. See
Chapter 6 of the Operators Manual for a discussion of the commands available for IEEE-
488 operation.
