6. Programming Channels and Frequencies
The RV-M8-UC modem has memory for up to 100 channels. A channel is a pair
of frequencies, one for transmit and one for receive. They may be different or
they may be the same. You may program any valid frequency into any channel
number. To program a channel, perform the following steps.
1. Change to the channel you wish to program, using the
ATFC
command.
ATFC x tt rr c ab
where x is the channel number,
tt
is the TX frequency in HZ or MHz,
rr
is the Rx frequency in Hz or MHz
c
is 4 for control channel, 0 for non-control channels,
ab
are the over-the air modulation options.
a.
a
is the bit rate index corresponding to the over-the-air bit rate to use:
0=4800 2L, 5=9600 2L, 6=19200 4L, 8=9600 4L, 0=4800 2L,
b.
b
is the channel bandwidth. 0=12.5kHz, 1=25kHz.
2. For Example, enter
ATFC 3 217.425 219.425 4 00
to set the channel 3
TX frequency to 217.425MHz and RX frequency to 219.425MHz, 4800 bps,
two-level modulation, narrow band channel.
3. Review the frequency setting with the
ATFC x
where x is the channel number
to display.
4. To display a
ll channel’s, use the
ATFC ALL
command.
5. Some data rates are not suitable for use on certain channel bandwidths. For
example, 19200 4-level modulation will not work on a 12.5kHz narrow-band
radio channel.
6.1. Initializing a new RV-M8-UC to factory defaults
Warning, this will erase all parameters, and may cause your RV-M8-UC to stop
working on your network.
