4.3 Terminal Mode Operation
The MULTIPLEXER UNIT Control Port (labeled RS-232 CONSOLE on the front
panel) is a console terminal port designed to facilitate setup of all parameters through the
use of a standard text based terminal or any terminal emulation program running on a
Personal Computer.
4-2 Terminal Connection
A notebook computer has become an invaluable tool of the Systems Engineer.
Connection to the computer is very straight forward. The only other hardware required is a
RJ-45 to DB9F adapter cable (see page 1-6 for pinout). The MULTIPLEXER UNIT's RS-
232 Console port acts as a DCE to the PC's DTE communications port. A convenient
application, provided with the Microsoft Windows
®
98/NT/2K operating systems, is
"HyperTerminal?". Set the properties to match the MULTIPLEXER UNIT control port
defaults as follows: Baud=19200, Data bits=8, Parity=None, Stop bits=1, and handshaking
=none. Make the appropriate connections, start the terminal application, apply power to the
MULTIPLEXER UNIT, then press ENTER on the PC keyboard. If you are using
"HyperTerminal?" the display should look like that on the following page.
