THE ACM FEATURE WILL AUTOMATICALLY SHIFT THE MODULATION UP AND DOWN
!
BASED ON THE MSE VALUE AND THE ABOVE SPECIFIED THRESHOLDS. IF YOU DO
NOT WANT THE RADIOS TO CHANGE SPEED SETTINGS THEN DISABLE ACM .
ATPC & TargetRSSI
ATPC and TargetRSSI work together to control the remote side power achieving
optimal signal strength. ATPC is an enable/ disable setting. Once enabled ATPC will
adjust the power of the remote side based on the local TargetRSSI setting. If the RSSI
value is lower than the TargetRSSI setting of the local radio, the remote radio will
attempt to increase the output power in attempt to achieve the TargetRSSI setting.
ATPC has step size and max power settings to limit the output power of the unit and
prevent a violation of the FCC license.
POWER SETTING CAN NOT BE CHANGED ONCE ATPC IS ENABLED. IN ORDER TO
!
MANUAL CHANGE THE POWER ATPC WILL NEED TO BE DISABLED.
ATPC Max Power & Step Size
The ATPC Max Power and the Step Size control how the ATPC function will behave in
attempting to achieve the TargetRSSI. ATPC Max Power is the maximum power setting ATPC
can set the power output to when trying to reach the TargetRSSI. The ATPC Step Size is the
amount of dB per attempt that ATPC can change power output.
