4.1 General
The ETU-01A Control Port, sometimes referred to as a Craft
port, (labeled RS-232 on the front panel) is a console terminal
port designed to facilitate setup of all parameters through the use
of a standard text based (ANSI) 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 of the ETU-01A to the computer
is accomplished by a DB9-pin one-to-one, male to female cable.
The ETU-01A acts as a DCE to the PC’s DTE communications
port. A convenient application, provided with the Microsoft
Windows® NT/9X operating systems, is “HyperTerminal ”.
Set the properties to match the ETU-01A control port defaults
as follows: Baud=9600, Data bits=8, Parity=None, Stop bits=1,
and handshaking =None and use a direct connection to the PC's
COM port. Set the terminal emulation mode to ANSI. Make the
appropriate connections, start the terminal application, apply
power to the ETU-01A, then press ENTER or SPACE on the
PC keyboard. If you are using “HyperTerminal ” the display
should look like that on the following page.
