RF Configuration Menu option “0” is non-adjustable and indicates that the radio is
usable only in the 406.1 – 430 MHz and 450 – 470 MHz licensed frequency range.
Maximum Separation
RF Configuration Menu option “1” is the distance between the master unit and the
farthest slave (or repeater) unit that is connected to the master. The specified distance
sets the delay for receiving an ACK from a slave and determines the propagation delay.
Generally, network data rates are slower when distance increases. A short distance will
have less delay and a higher throughput. However, setting this parameter to a value
that is less than the actual separation can result in higher error rates.
Important:
this
parameter must be the same for all radios in a given network.
RF Transmit Power (“MAS transmit power”)
RF Configuration Menu option “2” is used to set the transmit power (in milliwatts) of the
radio within the limits of the radio certification. This parameter sets the power as
measured at the radio connector and does not compensate for any interconnecting
cable loss, antenna gain, or power lost due to impedance mismatch from the connected
load. The transmit power is dynamically adjusted to maintain this value as conditions
change within the limits set. Additionally, thermal monitors continuously measure the
output amplifier of the radio and can reduce the power level if the temperature rises
above a predefined set limit.

Maximum Separation
This parameter specifies the maximum distance in km between radios.
Larger values result in lower throughput due to time allocated for
propagation delay.
Current value = 10 km
