  • Page 10: Configuration

    MReX-SatLink User Manual v3.80 Firmware Configuration To configure the MReX-SatLink unit, connect to the unit RS422 serial port. Alternatively, configura- tion can be performed through the internal TTL connector. For details on using this connection, refer to section Internal Hardware -> Internal TTL Serial Connection. Parameters can be changed using any common serial terminal program.
  • Page 11 Note: Some configuration options are only applied to the unit on startup. It is a good practice to restart the unit after changing configuration to avoid unexpected behaviour. This can be achieved by removing power to the unit or sending the *REBOOT<CR> command. Page 11 of 89 © WTE Limited, 2023 – Christchurch New Zealand...

    ASCII Protocol Overview The MReX-SatLink can accept messages for transmission over the Swarm network using the plain- text ASCII protocol. This protocol is used over the external RS422 connection, and consists of a con- figurable start character, followed by the message payload. The default start character for the ASCII protocol is ‘$’.

    Failure to follow these instructions will result in equipment failure and will void the unit warranty. The WTE SatLink is equipped with multiple input and output options for the purposes of measure- ment and control. These include four digital inputs, four open-drain outputs and eight analog in- puts.

  • Page 60: Digital Inputs

    (see section Modbus for further details) or through the message macro functionality (see sub-section Macros of the Protocols section for further details). Digital inputs are accessible via the terminals labelled In0 – In3. Page 60 of 89 © WTE Limited, 2023 – Christchurch New Zealand...

  • Page 61: Analog Inputs

    Failure to follow these instructions will result in equipment failure and will void the unit warranty. There are 8 analog inputs available on the MReX-SatLink, with different inputs designed to operate over different input voltage ranges. Analog input values are represented as 10-bit integers (0-1024) which range proportionally between 0V and the maximum allowed voltage of a given input.
