How to Set up the RS-232 Host Port for Remote Control
The Calibrator is fully programmable over an RS-232 link with a PC the rear panel
SERIAL 1 FROM HOST port (Figure 5-2). You can enter individual commands from a
terminal, write your own programs using, for example, a Windows-based language such
as Visual Basic, or run optional Windows-based Fluke software such as 5500/CAL or
MET/CAL.
The RS-232 cable length for the port should not exceed 15 meters (50 feet), although
longer cable lengths are permitted if the load capacitance measured at a connection point
(including signal terminator) does not exceed 2500 pF.
RS-232 Host Port Setup Procedure
Complete the following procedure to set up the SERIAL 1 FROM HOST port. The
RS-232 parameters you select here must match the parameters set for the PC COM port.
The factory defaults (shown on the display below) are 9600 baud, 8 data bits, 1 stop bit,
and no parity. Other parameters include flow control, EOL (end-of-line) character, and
EOF (end-of-file) characters.
1.
Turn the Calibrator power on. You may operate the Calibrator during warmup, but
specifications are not guaranteed until warmup is complete.
2. Press

on the Calibrator front panel.
3. Negotiate the softkey selections shown below to select the serial port for remote
operation, then continue to Step 4.
