Service Mode
RMS supports a service mode where no errors will be reported. Service mode is
designed to allow a technician to work on a room without causing error reports.
For instance, if a projector needs to be replaced or serviced, RMS would report
Device Not Communicating when the technician disconnected the power cable or
communication cable. To prevent this error from being reported to RMS, put
RMS in service mode using the 'SERVICE-ON' command. When the work is
completed, exit service mode using the 'SERVICE-OFF' command.
Since service mode bypasses error reporting, it represents a security problem. For
instance, in service mode no error is reported when the projector stops
communicating even if it is being disconnected by unauthorized personnel.
Therefore, service mode does not appear as a button on a touch panel. Service
mode should be implemented in an appropriate method for the facility. These
methods may include:
A button on a protected touch panel page
A button on a protected web-based touch panel page
A switched connected to an IO port on a NetLinx system accessible
only by technicians.
A key-activated switch connected to an IO port on a NetLinx system.
Device Parameter Persistence
Monitored devices and parameters are registered with RMS the first time a
NetLinx system connects to the RMS server. These devices and parameters are
stored internally in RMS. When NetLinx connects and sends device and
parameter registration, any devices and parameters that already exists in RMS are
not overwritten. This allows the administrator to change a value, such as the lamp
life threshold of a projector, and the value will not be lost even if the NetLinx
systems disconnects and reconnects.
As a result, changes to device monitoring NetLinx code will not take affect if the
changes are made to devices or parameters that already exists in RMS. For
instance, if you change the threshold value for a parameter or delete a device or
parameter and reload the NetLinx code, the new threshold will not be used and
any deleted device or parameters will still appear in RMS.
