Appendix L – 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. 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 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 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 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.
