Appendix A – TAP Interface Specifications
This appendix is included for those who want to develop their own paging control software or add an interface for the
WaveWare v9E
Paging Encoder to their existing software applications.
A simple definition of the TAP Protocol is that the TAP Protocol normally requires a connect and disconnect process and
normally assumes that the Host system maintains a database of pager reference numbers called IDs, and that the paging
system maintains a database of all paging parameters associated with each ID. The TAP Interface supports paging
messages up to 244 characters in length. The actual maximum length of transmitted messages in the WaveWare
SPS-5
v9E TAP Interface is 245 minus the ID field length. With an ID value of 5, you can transmit up to 245 characters per
message. With an ID value of 1233425120, you can transmit up to 235 characters per message.
To configure your WaveWare v9E
Paging Encoder to use the TAP Paging Protocol, you may be required to configure
the com port settings and/or network connections in the paging encoder
The WaveWare v9E
Paging Encoder maintains an input buffer which can receive commands from the PC while a page
is being transmitted. The input buffer should be able to contain approximately 100 paging messages before getting full.
When a command is received from the PC, the paging system responds with a message that includes error messages if
the command was not understood or not properly transmitted. The first three digits of each paging system response
conform to the response codes defined in the TAP v1.8 specification.
See Appendix D – TAP Response Codes for a listing of the response codes.
The WaveWare v9E
Paging Encoder encodes paging messages into
POCSAG
paging format and transmits the
encoded paging message. If the Carrier Detect function is enabled, transmissions will be delayed while interfering signals
are detected.
