Permanent Primary Activation
If programmed, a DVRS can be forced to be a Permanent Primary from the MSU CH.
NOTE:
If another Permanent Primary is already present, the newly activated Permanent Primary
DVR will f
orce the “old” Permanent Primary to assume Permanent Primary ‘On Standby’
Status. If the
Permanent Primary leaves the scene, the Permanent Primary ‘On
Standby’ takes over. If several users try to simultaneously activate several DVRS as
Permanent Primaries, the DVRs will go through voting to ensure only one Permanent
Primary DVR is selected and all other DVRs are forced to become Permanent Primary
‘On Standby’.
Permanent Primary Deactivation
The Permanent Primary status of a DVRS can be switched off from the MSU CH.
Legacy Mobexcom II Voting Compatibility Mode
The voting compatibility mode is applicable to analog DVRS mode only. If Legacy
Mobexcom II Voting Compatibility mode is enabled in the DVR, its voting algorithm is
compatible with older style analog only Mobexcom II VRs. Enabling this feature allows
seamless replacement of old style VRs with the new DVR by supporting the deployment
of both types of units in the same fleet during the transition period.
