CalAmp Guardian-100 User Manual page 49

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 GUARDIANs must be setup 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.
Under the "Utilities" menu choose the "ASCII Terminal". From the "ASCII Terminal" screen, choose the
"Primary" selection. This will open an ASCII terminal window using the primary COM port of the
computer. This procedure should be done for both GUARDIANs.
The ASCII Terminal utility has provisions for transmitting the ASCII data, displaying received ASCII
data
and displaying ASCII transmitted data. Figure 2-23 shows the window for the Primary ASCII Terminal.

Figure 2-23 End to End Test: ASCII Terminal
Figure 2-23 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
computer‟s
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 as shown in Figure 2-24.
