Overall steps to this article:

  1. Update DV​X central C​ontroller version then Switcher version
  2. Update DXLINK endpoints

Step 1:

The order of loading the firm​​ware is to update the central controller first, then update the switcher.

  1. Load SW2106_NX-X200_Controller_v1_8_107.kit to device 0, wait for the DVX to reboot and come back online​​.
  2. Load SW1906_25A_SWITCHER_v1_9_7.kit to device 5002.  The DVX will reboot and the 5002 will begin the update.  Do not power cycle the DVX until the 5002 has fully completed the update and is back online in Netlinx Studio. The front panel of the DVX shows the update status.
  • IMPORTANT:  This upgrade can take from 30 min to 2 hours depending on the starting firmware.  Please be patient and don't reboot the DVX until it is done.
  • Note: It is recommended to send the command ?FWVERSION to 5002:1:0 before and after the upgrade and keep the responses handy so you can verify all components have updated correctly. See Readme for details.

Step 2:

**If the link takes you to the product page of a device, find the newest revision under downloads.

If you have DXLINK Transmitter or Receiver endpoints, please update their firmware also.
