Power up the X4 Rugged Encoder

There is no power switch on the encoder. The power is automatically on when the unit is plugged in.


When using the AC/DC power adapter, the power cord is the main disconnect device. Ensure that the socket-outlet is located/installed near the equipment and is easily accessible.

ATTENTION Quand on utilise l'adaptateur AC à DC, le cordon d'alimentation est utilisé comme interrupteur général. La prise de courant doit être située ou installée à proximité de l'équipement et être facile d'accès.

To power up the encoder:

  1. Insert the 4-pin connector of the power cable into the power input jack (DC IN) at the rear of the encoder. Both power cables are shipped as part of the Evaluation Kit (#S-MX4E-R-SDI4-ISR-DK). 

    Make sure the connector is properly inserted and locked to avoid intermittent power problems. 
  2. Connect the power cable to a 28V power source. (The AC PSU can be used to convert from 120V AC to +24V DC.)
    The Status LED next to the video inputs will start blinking green, indicating that the encoder is booting up.
  3. Wait until the Status LED stays solid green, indicating that the encoder is ready for operation.


The encoder performs Built-in Self Tests (BIST) and Power-On Self Tests (POST) to ensure that the hardware and firmware are operating reliably and correctly. BIST provides a minimal suite of tests that test the various hardware and firmware sub-systems to ensure correct operation. The POST suite of tests (a subset of the BIST suite) are performed every time there is a power-cycle. All BIST/POST configuration, status and test results are available via CLI (serial, Telnet or SSH). For more information, please refer to bist (in the Makito X Encoder User’s Guide, CLI Command Reference).
