Paging System Operation
Your SPS-5 Paging System includes a either VHF or UHF transceiver, and onboard RS-232 communications, that
transmits paging messages using the industry standard POCSAG paging protocol. The RS-232 communications
allow you to interface the paging system to a PC or to other devices and systems that use RS-232 serial
communications (Host Devices). Other models of SPS-5 Paging System products include encoder only models, and
the combination of the paging encoder with VHF and UHF radio transceivers.
The types of paging receivers that are compatible with your SPS-5 Paging System include:
• Any POCSAG compatible paging receiver operating on the same frequency as the paging transmitter (in the
UHF band) and operating at 512, 1200, or 2400 bps data rate. Pagers of this type include tone/vibe, numeric,
and alphanumeric models and can be obtained from WaveWare Technologies, Motorola, NEC, Panasonic,
Maxon, TEKK, and others.
• WaveWare Wireless Message Centers, operating at the same frequency as your paging system.
WaveWare Wireless Message Centers are normally configured to receive at a 2400 bps data rate.
The paging system may be controlled by a PC, or other control system, that is running software designed to interface
to the paging system. WaveWare wireless communication systems software is designed to take full advantage of the
features of your SPS-5 Paging System. The TAP, COMP1, and COMP2 interface protocols are defined in this
handbook to allow you or others to develop software or devices to directly control the transmitter.
The paging system maintains an input buffer, which can receive commands from the Host Device while a page is
being transmitted. When a command is received from the Host Device, the paging system responds with a message
back to the Host Device. The paging system encodes the paging messages into POCSAG paging format and
transmits the encoded paging message to the paging receivers of your choice.
PC software developed to utilize the SPS-5 Paging System can be designed to maintain a simple database of pager ID
numbers, or the software can be designed to allow definition of paging receiver attributes, including:
• Pager Type
⇒ Tone/Vibe Only, with or without multiple tone/vibrate cadences
⇒ Numeric
⇒ Alphanumeric
• Capcode - The unique address assigned to each paging receiver
• RF Data Rate
⇒ 512 bps
⇒ 1200 bps
⇒ 2400 bps
Refer to Appendix A – TAP Interface Specification for details on how to control the SPS-5 Paging System via the
TAP protocol. Refer to Appendix H – COMP1 Interface Specification for details on how to control the SPS-5 Paging
System via the COMP1 protocol. Refer to Appendix I – COMP2 Interface Specification for details on how to control
the SPS-5 Paging System via the COMP2 protocol. Refer to Appendix J - Timer Triggered Messaging for details on
how the Timer Triggered Messaging function operates. Refer to Appendix K - Contact Monitoring for details on how
the Timer Triggered Messaging function operates.
The Transmitter Unit may require the setting of an onboard DIP switch to change communication interface
parameters. Refer to Appendix B – DIP Switch Settings for details on how to configure the DIP switches, as required.
If you want to use the TAP interface protocol with 1 to 4 digit pager IDs, you will need to configure a pager database,
using the WaveWare Paging Encoder Setup software. You can obtain the WaveWare Paging Encoder Setup
software from the WaveWare web site, at http://www.wirelessmessaging.com
