5-5. Setting up the RS-232 Host Port for Remote Control
The 5500A 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.
5-6. 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 below in bold) 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 5500A Calibrator power on. You may operate the calibrator during
warmup, but specifications are not guaranteed until warmup is complete.
2. Press the S key on the 5500A Calibrator front panel.
3. Negotiate the softkey selections shown below to select the serial port for remote
operation, then continue to Step 4.
