Appendix K – Timed Messaging Function
The
Timed Messaging Function
is designed to allow the
WaveWare v
8
Paging Encoder
to be used for purposes of
automatically transmitting pre-defined messages upon timer related conditions. The
Timed Messaging Function
can be
activated during the process of programming the pager database using the WaveWare Paging Encoder Setup software.
The
Timed Messaging Function
is available in all modes of operation. 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 system while the
Timed Messaging Function
is active, the paging system will transmit predefined messages
as defined in the pager database configuration.
The Timer
is reset under the following conditions if the
Timed Messaging Function
is active:
Reception of a valid
TAP Protocol
formatted control string on the serial port
Reception of the
ATI<CR>
control string on the serial port
When programming the
WaveWare v
8
Paging Encoder
pager database, each of the ten pager groups of up to 20 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 of up to 60 characters in length. 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 system
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.
