• Operation mode – select Receiver for Rover stations; select
Off if the radio is turned off; select Transmitter for Base
stations.
• Output power – enabled only when Transmitter selected,
this field adjusts the transmission power of the Base
station’s radio modem.
• Link Rate – select the data transmission rate for the RF
link; either 9600, 12000, 17000, 24000, or 51000 bps.
As opposed to a baud rate (the rate of data transfer through
a serial cable interface), the link rate is the amount of data
(measured in bits) the radio modem can transmit/receive
over the air in a specified time period (measured in
seconds). Table 2-3 shows the relationship between the
radio interface link rates and the serial interface baud rates
used at the transmitter and receiver(s) ends.
