How to Test RS-232 Host Port Operation with a Terminal
Complete the following procedure to test RS-232 Host port operation using the Windows
Terminal accessory (or equal).
1. Complete the “RS-232 Host Port Setup Procedure” earlier in this chapter to set up the
Calibrator for RS-232 Host port operation. Note the RS-232 Host port parameters
that you selected in this procedure.
2. Connect the selected COM port on the PC to the Calibrator SERIAL 1 FROM HOST
port using a standard null-modem RS-232 cable. (See Appendix C for information on
RS-232 cables and connectors.)
3. Open Windows to the Program Manager screen on your PC.
4. Open Terminal from the Accessory group of Program Manager (below). If a terminal
configuration file already exists, e.g., host.trm, select the desired file using the
Open command from the File menu and go to Step 7. Otherwise, go to Step 5.
