A.7.2.3 Cold Start
The cold start function, if enabled, mutes the output signal for a predetermined time following
Power-Up to ensure a stable reference oscillator (15 minutes). The default is OFF. This
command is disabled in redundant systems (i.e., COMMAND NOT AVAILABLE).
Command Details
Set Cold Start: <DEV/CLD_xxx'cr' xxx = ON or OFF
Confirmation: >DEV/CLD_xxx'cr''lf']
Retrieve Status: <DEV/CLD_'cr'
Confirmation: >DEV/CLD_xxx'cr''lf']
A.7.2.4 Mute
The default RF mute state is ON (output is muted).
Command Details
Mute Output: <DEV/MUT_xxx'cr' xxx = ON or OFF
Confirmation: >DEV/MUT_xxx'cr''lf']
Retrieve Mute Status: <DEV/MUT_'cr'
Confirmation: >DEV/MUT_yyy'cr''lf']
yyy = ON/OFF/COLD
A.7.2.5 Carrier Mute Mode
The carrier mute mode determines the mute state of the unit during frequency changes. The
default carrier mute mode state is OFF (output is muted during frequency changes).
Command Details
Mute Mode: <DEV/CMM_xxx'cr' xxx = ON or OFF
Confirmation: >DEV/CMM_xxx'cr''lf']
Retrieve CMM Status: <DEV/CMM_'cr'
Confirmation: >DEV/CMM_xxx'cr''lf']
A.7.2.6 Redundant Mute Mode
The redundant mute mode determines how the backup unit handles the mute state during a
redundant switchover condition. If the redundant mute mode is ON then the backup unit’s mute
state will be the same as the primary unit that it is backing up. Otherwise, if the redundant mute
mode is off the backup unit will unmute its output any time a redundant switchover occurs.
The default redundant mute mode state is OFF (backup unit’s output automatically unmutes when
a redundant switchover occurs).
