MReX-Multi Telemetry I/O Expansion Module 

 The MReX Multi-IO is a 16-input 16-output addressable digital IO module with RF and RS422/485 serial connectivity. This product is ideally suited towards applications that require remote monitoring and control of large amounts of I/O. The MReX-Multi-IO provides flexibility and customisability to suit the needs of many different projects.  The MReX-Multi can operate as a POCSAG paging transceiver, and can directly message POCSAG pagers if required.   
Paging Transceiver with Expansion IO
MReX-Multi Paging Transceiver with 16 Inputs and 16 Outputs.
Features
  •  16 electrically isolated digital inputs.
  •  4 relay outputs.
  •  12 open-drain digital outputs.
  •  RS422 serial connection.
  •  Sends and receives 512, 1200 and 2400 baud POCSAG paging messages.
  • Sends telemetry data from 512 baud to 9600 baud
  • Configured inputs can be programmed to send POCSAG messages simultaneously when triggered.
  • Configured outputs can be controlled via paging message.  
  • Periodic message support to ensure link integrity.
  • Firmware upgradable.
  • High stability 0.5PPM oscillator ensuring minimal drift over the entire specified temperature range.
  • Output power up 100mW.
  • Operation from 421 to 480 MHz.
  • High sensitivity receiver (-127dBm at 512 baud).       
  • Expansion support for an unlimited number of devices.

Flexible IO Expansion

Many IO configurations are possible.  Expansion is possible up to 10 units directly wired via RS422, or an unlimited number of wireless units - allowing for system support of any number of inputs or outputs.   Because the MReX-Multi also acts as a standalone paging transmitter, messages can be sent directly to a pager or DMR radio, meaning that a complete system could be a simple as a single MReX-Multi and a receiving belt pager.   The MReX-Multi is well suited as a POCSAG output control module for simple telemetry control applications.​
Paging System with Expansion IO
Basic system with one WTE device controlling/monitoring a large number of units.
As an example,  a central control unit (either a Multi-IO unit or a TReX-460) needs to control the outputs of 5 units remotely via RF link. The remote units consist of one RS422 master unit that maintains an RF link with the control unit and 4 RS422 slave units which report their I/O to the RS422 master unit.
