11-74 Pocsag Encoder with 12 discrete inputs

11-74 is a Pocsag encoder which can be controlled via an RS232 serial interface to provide numeric, alphanumeric and tone-only encoding. This enables a user to call a pager (over 2,000,000 codes), append an appropriate priority level (1 to 4), and add a numeric or alphanumeric message. Messages are limited to 120 characters by the 11-74 buffer size, and to 240 character pre-defined messages. Serial control is achieved using ASCII character commands.

12-06 POCSAG ENCODER

The 12-06 is a simple POCSAG 512bps message generator integrated into a serial lead suitable for interface with 11-72 & 11-78 transmitters or similar.

Serial communications with PC is 9600bps, N, 8, 1. 1200 and 2400 bps are also available. The data rate is fixed on both ports and is not adjustable.

The 12-06 will handle up to 900 characters of message. A PET password is not required.

No installation required, simply plug the D9 socket of the 12-06 to a serial port on the PC and the second D9 to 11-72 or 11-78 transmitter. The 12-06 is powered from the transmitter.

11-97 Data modem

The 11-97 1200 baud Radio Data Modem is a low cost user-configurable Full Duplex AFSK modem (modulator/demodulator) capable of data speeds up to 1200 baud. The modem is compatible with the CCITT V.23 standard.

Various baud rates allow a data rate of between 0 and 120 bytes per second on a coventional 3 kHz bandwidth carrier. No data processing or bit synchronisation occurs in the modem, allowing the external devices total control over data protocols and formats.

A power saving mode can be enabled. This turns off the RS232 drivers whilst the radio is not busy, and allows a 30% saving in power consumption in standby.

Where no RTS signal is available, a novel automatic PTT system can be enabled, which asserts the Radio PTT when data is sent to the modem. This requires preamble in the transmitted data stream.

The Clear to Send CTS output is derived from the Busy signal from the radio, and can be link selected active High/Low, or looped back to make it dependent on the RTS (PTT) input.

The Data Carrier Detect output of the modem is derived from an AFSK carrier energy detector, and its state can be monitored by the LED. The output on the comms connector can be link selected active High/Low. Received data is gated with the DCD signal, to stop corrupted data output when no carrier is present.

The unit is housed in a rugged die-cast aluminium case with D type connectors.
