  MODES OF OPERATION
The transceiver transmits data according to three possible modes:
  Scheduled Reporting
The transceiver is designed to transmit data according to a programmed schedule. This could be
every 15 minutes or up to once a day depending on the type of subscription provided and the services
offered by the service provider.
  Event Response
The transceiver will transmit when a critical sensor alarm point is exceeded or when other internal
set points are triggered. As an example of an internal set point trigger, the transceiver could be
configured to transmit data when the unit goes from ‘ready’ mode to ‘sleep’ mode. Sensor limits are
set using optional EZ-LAN support software.
  User Request
Data from the transceiver can be retrieved via a user-generated request via the internet interface.
The SSMS Terminal features a ‘sleep’ mode when it is running on battery power. When in ‘sleep’ mode,
the SSMS will wake itself up according to the schedule and transmit its report. When in the ‘sleep’ mode,
the SSMS will also wake itself up at increments (depending on the subscription and service provider) of
the scheduled transmission time and look for – and if necessary respond to -event responses and polls.
Consequently, transceivers that are polled when in sleep mode will transmit with a delay dependant on
the type of service to which the unit is subscribed. For exact times please consult your service provider.
The ‘wake-up’ intervals are determined by the subscription type and is set by the service provider.
The transceiver has an additional battery saving mode that is activated when the battery drops below
10VDC. This function is designed to prevent battery damage caused by deep discharging the battery.
