Figure 1 (Packet Mode of Operation)

6.1 Setup
1. Connect a DC power source to the DC IN connection on the front of the modem.
2. Connect a good quality antenna, cut to the operating frequency, to the BNC connector on
the front of the modem. Use a good antenna, and place is at high-above obstructions as
possible.
3. Connect a computer terminal, or PC computer running HyperTerminal, to the 9-pin I/O
connector. The factory default serial ports settings are 9600 bps, 8 data bits, 1 stop, no
parity.
4. Program the modem’s operating frequency to your desired operating frequency. This is
done with the ATFX xxx.xxxxx command. See the section “Serial Port Commands” for
information describing the various parameters that may be modified in the modem. In most
applications, the default settings from the factory will work fine.
5. Using the AT commands, change any of the default operating parameters that must be
modified. From the factory, the modems are configured and shipped ready-to-use. Out of
the box, they will communicate on the default radio channel using the factory defaults. In
general, the parameters you may want to modify will be:
