APPENDIX K – TIMED MESSAGING FUNCTION
The
TIMED MESSAGING FUNCTION
is designed to allow the WaveWare v9E Paging Encoders to be
used for purposes of automatically transmitting pre-defined messages upon timer related conditions and is
activated during the process of programming the
GROUP PAGING
database.
THE TIMED MESSAGING FUNCTION OPERATES AS FOLLOWS:
Concurrent with the encoder monitoring the serial port for normal paging messages,
the Timed
Messaging Function uses an internal 2 minute timer cycle to determine whether or not to transmit
predefined messages.
If the timer is not reset by the host device while the Timed Messaging Function is
active, the paging system will transmit predefined messages as defined in the pager database configuration.
(
Note:
Either Ethernet Activity Resets Timed Paging or Serial Activity Resets Timed Paging must be active in
order to be able to reset the timer, depending on the input used to send paging data
.)
THE TIMER RESETS UNDER THESE CONDITIONS WHILE THE TIMED MESSAGING FUNCTION IS ACTIVE:
•
RECEPTION OF A VALID TAP OR COMP2 FORMATTED STRING ON THE SERIAL PORT.
•
RECEPTION OF THE ATI<CR> CONTROL STRING ON THE SERIAL PORT.
When programming the WaveWare v9E Paging Encoder’s pager database, each of the ten pager groups
of up to 15 pagers per group in the pager database can be associated with the Timed Messaging Function
and associated with one of up to 15 configurable predefined messages. If a pager group has the Timed
Messaging Function active, all pagers in that pager group will receive a predefined message.
SOME PRACTICAL APPLICATIONS OF THE TIMED MESSAGING FUNCTION ARE AS FOLLOWS:
In mission critical environments,
the Timed Messaging Function can be used to monitor the host
device and notify someone's pager that the host system needs attention
. To accomplish this, program the
host control software to output a TAP message or the ATI<CR> command every minute. If the host gets
disconnected from the paging system or the host stops functioning, the Host Monitoring Function will come
into play.
Use the Timed Messaging Function in a supervisory controlled paging system environment to
allow
other portions of the system to know that the paging system's encoder and transceiver are functioning
properly
, by monitoring for the predefined message being transmitted automatically by the paging system.
