(4) RF Data Rate
•2 when the radios are closer together and data throughput is to be optimized.
•3 when the radios are farther away and a solid RF data link is preferred over data throughput.
Note: The RF Data Rate setting must be identical for all units in the system. Any radio modem with a different
RF Data Rate than the master will not establish a communication link.Sets the RF Data Rate for the over-the-air
communications rate.
(5) RF Xmit Power
Sets the radio output transmit power. The table below shows the typical power breakdown.
Value
SRM 900MHz (1W Power) SRM 2.4GHz (500mW Max) PLR 900 MHz (200mW Max)
mW dBm mW dBm mW dBm
0 5 +6 0.5 -3 5 +6
1 75 +18.7 20 +13 10 +10
2 115 +23.5 60 +18 25 +14
3 325 +25 125 +21 60 +17.7
4 450 +26.5 200 +23 95 +19.7
5 550 +27.4 300 +24.8 125 +21
6 675 +28 350 +25.4 140 +21.5
7 750 +28.7 400 +26 155 +21.9
8 825 +29 430 +26.3 165 +22.1
9 925 +29.6 450 +26.5 185 +22.6
10 1000 +30 500 +27 200 +23
Note: The output power in the table may slightly very from transceiver to transceiver, but the output power will
never exceed the RF Xmit Power settings of 10 dBm specications from the table below.
(6) Slave Security
Sets the security mode of a remote in a call book based system to only accept connections from radios in the remote units
call book.
•0 to enable security.
•1 to disable security.
This may need to be disabled if the radio is operating in a point-to-point system where calls from more than 10 different
radios may be needed.
Note: With Slave security disabled the radio will accept calls from any unit calling this remote and additional system
security measures should be taken to prevent unauthorized access.
(7) RTS to CTS
Sets the RTS line on the master radio to control the CTS line on the remote.
•0 to disable RTS pass-through.
•1 to use RTS to CTS pass-through.
This pass-through control can be enabled in point-to-point mode as well as point-to-multi-point. In the latter, the master
