Description

Description

The 12-38-0000 transceiver is capable of accurate control and telemetry over long distances. Designed to be used in hostile environments it can withstand temperature extremes as well as being resilient to electrical noise often found in industrial plants.

The transceiver, along with its integrated input/output interface, is designed for the control and telemetry of industrial machines with high accuracy and speed.

The on-board SD card is used to store the configuration of the unit for easy swap-out, and can be also store log and audio wave files. The unit could be made to respond to an event by seizing a radio channel and broadcasting the wave file audio. Anyone carrying a radio transceiver could receive the message.

The 12-38-0000 is a 5 watt analogue transceiver with POCSAG capability for both transmitting and receiving and comes in two variants, a VHF (136-174 MHz) or UHF (440-470 MHz). All parameters are programmable such as frequency, power output, deviation, POCSAG data transmission, etc..

The USB port, or the RS232 serial port, can be used to initiate paging transmissions using the SALCOM proprietary protocol, Paging Entry Protocol (PET) or Telocator Alphanumeric Protocol (TAP) PG1 protocol.
