Radio Baud
Rate
Indicates the speed on the Radio:
_ '0': 1200 Bits/s,
_ '1': 2400 Bits/s,
_ '2': 4800 Bits/s,
_ '3': 9600 Bits/s,
(Default)
_ '4': 19200 Bits/s,
_ '5': 38400 Bits/s,

: 0~255 (VW2500A)
Default: 0

Radio Power
Power of the Radio.
_ '0': -5dB, -6dB for VW2500A
_ '1': 0dB, -4dB for VW2500A
_ '2': 5dB, -2dB for VW2500A
_ '3': 10dB (Default), 0dB for VW2500A

FEC Enable
/Disable
FEC (Forward Error Correction) Control:
_ '0': Disable
(default)
_ '1': Enable
When FEC enabled, Redundancy is added to the
transmitted data in such a way that the receiver can
restore the original data in the presence of some bit
errors, and thus extending communication range.
As the redundancy data addition, when enabled, the
effective data rate is halved.
This register is only applied to VW1100A &
VW2500A.

Frequency
compensation
Frequency compensation
This register is specially applied to VW1205A for the
narrow band operation.
When two module locate at very different
temperature locations (e.g., indoor and outdoor in the
cold winter), the 2 frequencies might drift out the
narrow band, then this register can be used to
compensate it.
When it is set to 128, and do a power reset, the
module will read back the default setting.
