7.1. Setup
1. Connect a DC power source to the M6.
2. Connect a good quality antenna tuned to the operating frequency, to the RF
connector on the front of the modem. Use a good antenna, and place is at
high-above obstructions as possible. The antenna should always be connected
when the power to the unit is on. Removing the antenna when the unit is
transmitting may damage the power amplifier in the unit.
3. Connect a computer terminal, or PC computer running HyperTerminal or
Raveon’s Radio Manager, to the 9-pin I/O connector. The factory default serial
ports settings are 9600 bps, 8 data bits, 1 stop, and no parity.
4. Program the mod
em’s operating frequency to your desired operating frequency.
This is done with the
ATFX xxx.xxxxx
command. For MURS versions of this
product, change the channel with the
ATHP x
command, or use
ATHP
command with no parameter to read the current channel and frequency.
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:
