Set up the RS-232 UUT Port for Remote Control
The SERIAL 2 TO UUT serial data port connects a UUT to a PC or terminal with the
Calibrator (Figures 5-1 and 5-2). This “pass-through” configuration removes the
requirement for two COM ports at the PC or Terminal. The UUT_* commands (see
Chapter 6) are for the UUT port data flow.
The RS-232 cable length for each port must not be more than 15 meters, although longer
cable lengths are permitted if the load capacitance measured at a connection point
(including signal terminator) is not more than 2500 pF.
RS-232 UUT Port Setup Procedure
Complete the subsequent procedure to set up the SERIAL 1 FROM HOST port. The
RS-232 parameters you select here must be the same as 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 on the Calibrator power. You can operate the Calibrator during warmup, but
specifications are not guaranteed until warmup is complete.
2.
Push
on the Calibrator front panel.
3.
Navigate the softkey selections shown below to select the serial port for remote
operation, then continue to Step 4.
