Configuring a Digital UHF Radio Modem
P/N 7010-0816

Channel Select the desired frequency from the channel list.
Note: The same channel must be used for both the base
and rover to communicate properly.
Forward Error
Correction (FEC) Enable to maximize data communication. The rover radio
modem has the capability to check and correct
transmission errors (if any) in an incoming data stream.
Scrambling • For PDL w/EOT and TRMB protocols, enable
scrambling to provide more robust data
communication over high interference areas.
• Scrambling is not supported when Simplex protocol is
selected.
Output power Select the transmission
power for the radio
modem (from 10 mW
to 1W). n/a
Link rate Select 9600 as the link rate, which is the default link rate
for GMSK (recommended for most applications) and
DBPSK. The link rate is the rate at which data is
transmitted over the RF link.
For maximum efficiency, the data packet size transferred
to the radio modem in a given time should be equal to or
less than the link rate. See Table 3-2 on page 3-6 to
determine the link rate.
