How do I link my MX systems in the MX Field App?

This article discusses linking two or more systems together for flash synchronization in the MX Field App

Product applicability

The following products are discussed in this article:

  • MX Series: R920-MX, R247-MX, CHEVRON-MX and WWD-MX

There are a variety of scenarios where you will want flash synchronization by more than one system in the immediate vicinity of each other, such as crosswalk beacons or 24-hour warning beacons that face the same direction.

Follow the steps below to link more than one system together for synchronized flashing:

  1. Pair with one of the systems to link.
  2. Tap on Link Settings.
  3. Confirm there are no linked systems currently. Making any changes will break an existing link.
  4. Tap on vertical ellipsis, Custom Link and then Apply Link Settings.
  5. Disconnect from the system and pair with the next system to link to. Navigate to Link Settings, tapon the vertical ellipsis and then Paste Link. The app will list all systems you have copied settings from. Choose the one you wish to link to.
  6. Perform step 5 for all additional systems to link.
  7. The Linked Systems list will take a few minutes to show all linked systems. There will also be a color-coded linked label for these systems on the Nearby MX Systems screen. All systems linked will now have synchronized flashing.

For more information please see the MX Field App guide.

RRFBs are unique and automatically link to all available local RRFB systems. While this is convenient, we still strongly recommend you manually link every individual RRFB crosswalk.  If you have an issue with crosstalk between multiple crossings nearby you can create a new link for each crossing to isolate them from each other. Simply follow the instructions above to rectify this.

Manual linking will also help with accurate activation data in MX Cloud across all systems at the crossings.

Changing the channel is only required if you are having communication issues due to excessive noise on that part of the spectrum. Changing the channel on all systems at the crossing can help remedy this.

If you see a gray Linked icon with a flag, that signifies the RRFB system(s) are on the factory link settings and it is strongly recommended to manual link these systems.
