comp1

This is provided for those who want to attach the WaveWare Paging System to existing systems that output raw data or simple data strings that are normally used in printing status logs on serial printers. The COMP1 Protocol is designed to emulate one of the operational modes of the Motorola People Finder (tm) paging systems.

A simple definition of the COMP1 Protocol is that the COMP1 Protocol allows raw ASCII data to be sent to all pagers in the Group One list of the WaveWare Paging System's group database. The group lists must be defined in TAP mode using the WaveWare Paging Encoder Setup. The COMP1 Interface supports paging messages up to 255 characters in length, contact monitoring, and timed messaging.

To configure your WaveWare Paging System to use the COMP1 Paging Protocol, you may be required to configure the DIP Switch Bank in the paging encoder. Please refer to DIP Switch Settings, for details on configuring communication protocols. As a quick reference, the DIP Switch Setting for the COMP1 Interface is switch 7 in the "OFF" position and all other switches on the "ON" position. This tells the system to operate in COMP1 Interface mode, with communication parameters of 9600 N 8 1, with hardware flow control.

Your WaveWare Paging System typically communicates 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 communcation parameters. Please refer to DIP Switch Settings, for fetails on serial communcation parameters.

The paging system 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 message through the internal radio transmitter. If the Carrier Detect function is enabled, transmissions will be delayed while interfering signals are detcted.

COMP1 operation is as follows:

When incoming data is detected on the serial port, one of three things happen:
          1) A carriage return character is detected in the data stream
          2) A time period of approximately 10 seconds elapses after receipt of the last character on the serial port or
          3) 256 characters or more accumulate in the serial port input buffer.
If any of these three events occur, the paging system will strip any carriage return and linefeed characters and transmit the remainder of the datastream to all pagers defined in the encoder's pager database.

If the serial port input buffer becomes filled with grreater than 1000 characters, the paging system will output either a hardware or software flow control response, depending upon how DIP Switch 1 is configured. Once the serial port input buffer drops below 450 charcters, the paging system will use flow control signals to indicate that it is no longer busy and that additional data can be delivered to the serial port.

NOTE: When using COMP1 mode, please note that all data is transmitted to the pagers listed in the group one of the WaveWare Paging System pager database. When setting up for COMP1 operation, you should limit the pager quantity to no more than a few pagers, in order to avoid excessive paging transmissions.
