PLEASE, READ THE TEXT BELOW CAREFULLY !

Newer models of the Engine Gateway have more memory than devices manufactured
in 2016-2017. Firmware with the version 1.3x is designed for new devices, and
firmware with versions 1.2x are designed for old devices.

  1) If your device has the firmware below v.1.25, upgrade it to version 1.25
     first. This firmware checks the chip version and prepares it for upgrade
     to a 1.3x version. DO NOT UPGRADE YOUR DEVICE VERSION 1.27, YOU WILL NOT
     BE ABLE TO UPDATE TO VERSION 1.3X AFTER THAT. Copy all files from the
     FW125 folder to the root folder of MicroSD card, insert it into the
     Gateway and cycle the power of your NMEA 2000 network. Eject the card
     after 30 seconds and check the first lines of the YDEGSAVE.TXT file,
     it should contain the information that your device can be upgraded to
     version 1.3x or not.
  2) If YDEGSAVE.TXT contains the text "Device is ready for upgrade to 1.30
     version", copy all files from root folder of archive to MicroSD card
     and update the device to Version 1.32.
  3) If YDEGSAVE.TXT contains the text "This device cannot be upgraded to
     version 1.30", copy all files from the FW127 folder to the MicroSD card
     and update your device to Version 1.27.
  4) Before installing 1.50 version or later, you must first install update
     1.49 from the FW149 folder. After installing 1.49, wait for five short
     green LED signals and one long signal, after which the device will enter
     normal operating mode and can be updated to 1.50 or later as usual.
