automatically and begin running the programmed firmware.
5.21 END TO END TEST
The Field Programming Software has several useful utilities embedded in the program that assist in testing the wireless
modems. The testing setup requires a computer running the Field Programming Software attached to each user COM
port on the Guardian wireless modems. The Utilities will allow the user to send ASCII text or Hex characters through
the Guardians being tested.
The Guardian modems must be set up so that they have the appropriate receive and transmit signal levels for the test.
The signal strength will be much stronger if the units are tested on the bench compared to being tested in a field
installation. These signals must be attenuated or the output power level adjusted if the units are being tested on the
bench.
ASCII Terminal
Under the Utilities menu choose the ASCII Terminal. From the ASCII Terminal window, choose the Primary selection.
This will open an ASCII terminal window using the primary COM port of the computer. This procedure should be
performed for both Guardian modems.
The ASCII Terminal utility has provisions for transmitting the ASCII data, displaying received ASCII data and displaying
ASCII transmitted data. Figure 36 shows the window for the Primary and Secondary ASCII Terminals.
Figure 36 End-to-End Test using ASCII Terminal
The above figure also shows the area that is used to send an ASCII text message. The ASCII data message is typed into
this area. The ASCII text message is then sent out the first Guardian through the computers primary port once the
Send button is clicked. The sent ASCII message is then displayed in the Tx Data area of the ASCII Terminal window. The
ASCII message is transmitted to the other Guardian. The ASCII terminal program will display the received ASCII message
in the Rx Data area.
