WaveWare SPS-5 v9E - Manual (Page 46)

Appendix I – COMP2 Interface Specifications
This appendix is included for those who want to attach the WaveWare v9E Paging Encoder to existing systems that
output simplified paging system control commands. The COMP2 protocol is designed to emulate one of the operational
modes of the Motorola People Finder™ paging system. There are two possible response modes for COMP2, the Verbose
and Non-Verbose modes. The Verbose response mode has been designed to have human readable responses to
message inputs and certain errors. The Non-Verbose response mode has no readable responses in it.
A simple definition of the COMP2 Protocol is that the COMP2 Protocol allows a message formatted as
PagerIDMessage to cause the Message to be delivered to the associated PagerID defined in the WaveWare
v9E
Paging Encoder’s pager database. The COMP2 interface supports paging messages up to 253 characters in length,
group paging, contact monitoring, and timed messaging. The total length of the control string, including and
characters cannot exceed 256 characters. The PagerID field can be from 1 to 10 characters in length. PagerID field
lengths from 5 to 10 digits are assumed to be Extended Pager IDs (See Appendix E – Extended Pager ID Processing).
Carriage Return is the normal field delimiter in COMP2 Protocol, but the tilde (~) character is also supported as a
delimiter.
A COMP2 Protocol superset is also available; where a message formatted as PagerIDXMessage will cause
the message to be delivered to the PagerID using Function Code value of X. Values of X can include A, B, C, or D. An
example of a function code controlled COMP2 message using Function Code A and Pager ID 101 is 101ATest
Message
To configure your WaveWare v9E Paging Encoder to use the COMP2 Paging Protocol, you may be required to
configure the Com Port of the paging encoder. Please refer to Appendix B – Com Port and Network Settings, for
details on configuring communication protocols.
Your WaveWare v9E Paging Encoder will typically communicate with a PC or other host device via RS-232 at 9600
Baud, 8 data bits and 1 stop bit. The eighth data bit is ignored (no parity). You can configure the paging system for other
serial communication parameters. Please refer to Appendix B – Com Port and Network Settings, for details on serial
communication parameters.
The paging encoder maintains an input buffer, which can receive commands from the PC while paging messages are
being transmitted. The paging encoder encodes paging messages into
POCSAG paging format and transmits the
encoded paging message through the attached radio transmitter. If the Carrier Detect function is enabled, transmissions
will be delayed while interfering signals are detected.
Control characters recognized by the WaveWare v9E Paging Encoders in COMP2 Protocol mode include:
CARRIAGE RETURN $0D
LINEFEED $0A
TILDE ~ $7E
DELETE $7F or $FF
Control characters generated by the WaveWare v9E Paging Encoders in COMP2 Protocol mode when software flow
control mode is active include:
CARRIAGE RETURN $0D
XON $13
XOFF $11
ABANDON TRANSACTION $1E
The WaveWare v9E Paging Encoders, when using COMP2 Protocol mode, are controlled using control strings
formatted as follows:
Single Message Example using Carriage Return as delimiter:
PagerIDMessage
Single Message Example using Tilde as delimiter:
PagerID~Message~
