Transceiver / Repeater - UHF

12-90-0000

The 12-90 is a simple to configure POCSAG transceiver with high sensitivity receiver combined with a 60mW transmitter.

It operates over the frequency range of 440-479MHz decoding and encoding 512 or 1200 baud, alphanumeric or numeric messages. 

The 12-90 supports multiple message queueing and will queue upto four 73 character messages or multiple smaller messages.

The 12-90 is a simple to configure POCSAG paging transceiver with high sensitivity receiver combined with a 60mW transmitter. It operates over the frequency range of 440-479MHz decoding and encoding 512 or 1200 baud, alphanumeric or numeric messages.

The 12-90 can be used as:

  • A full paging transceiver, allowing both the encoding and decoding of paging messages.
  • A standalone receiver.
  • A standalone transmitter with channel busy check function before transmissions.
  • An autonomous paging store and forward repeater with duplicate message reject.
  • A point to point raw serial link.
  • A simple telemetry solution.

The 12-90 can be controlled via an RS232 serial interface to provide numeric, alphanumeric and tone-only POCSAG encoding. This enables a user to call a pager (over 2,000,000 codes), append an appropriate priority level (1 of 4), and add a numeric or alphanumeric message.

The 12-90 supports multiple message queuing and will queue up to four 73 character messages, or as many smaller messages that will fit into the available memory buffer. It also supports full batching of serially queued and input messages, ensuring that messages are transmitted quickly with minimal transmit on time. Pre-defined input messages can be configured using any serial terminal application and are limited to a maximum length of 40 characters.

The unit supports 2 discrete inputs with different pre-programmed messages on high and/or low transition. Provision to transmit a message more than once and variable time between transmissions are catered for.

The 12-90 supports Salcom relay control protocol to control one on board relay plus several “virtual outputs”. Virtual outputs can be used to remotely trigger input or periodic messages and provide a mechanism to acknowledge reception of messages. The 12-90, through the use of a virtual output, can transmit the received signal strength of the last received message allowing the receiver positioning and system health to be monitored. The 12-90 can be configured to automatically respond with checksum information of the last received message allowing robust, error free systems to be developed.

Expansion of the 12-90 is possible through the use of the 12-34 relay module and 12-32 input module, allowing any number or outputs or inputs to be supported.

The 12-90 utilises an intelligent self-adjusting channel busy check to prevent message collision or corruption which reduces the need to retransmit messages and increases confidence of delivery.

Customers are asked to please note that due to new packaging, antennas will not be automatically supplied with this product and should be ordered separately. UHF Helical Antenna with BNC part code is 19-09-4002.
