The Program Firmware pull-down menu allows the user to read or program the Guardian firmware
(GUARDIAN.LDR) or read or program the Guardian’s User Configuration File (GUARDIAN.CFG). The Guardian
Configuration file contains all of the user programmable parameters for the Guardian. The Guardian Firmware file
contains the operating software that controls the Guardian Modem.
The Guardian Configuration section is used to read or program a configuration file (*.CFG) to or from a Guardian
Modem. This is useful for programming a previously saved configuration file (see section 5.1.7 Writing/Reading
Guardian Configuration Parameters) into the Guardian Modem or to replicate a configuration across a number
Guardian Modems.
To read the configuration file from a Guardian Modem:
1.
Select the Read option in the Guardian Configuration section.
2.
Click the Browse button to select the path and filename of the location to save the configuration file.
3.
Click OK button to start the read. A message will be displayed when the file has been read and saved to
the PC.
To Program a configuration file into a Guardian Modem:
1.
Select the Program option in the Guardian Configuration section.
2.
Click the Browse button to select the configuration file to be programmed.
3.
Click OK button to start the programming process. A file transfer progress window will be displayed and a
message will be displayed when the file has been successfully programmed into the Guardian.
To Program a new firmware file into a Guardian Modem:
1.
Select the Program option in the Guardian Firmware section.
2.
Click the Browse button to select the Guardian Firmware to be programmed.
3.
Click OK button to start the programming process. A file transfer progress window will be displayed and a
message will be displayed when the firmware file has been successfully programmed into the Guardian.
The Guardian will reset automatically and begin running the programmed firmware.

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 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,
