10. Connecting Multiple Controllers
Up to 32 controllers can be used in a single installation in order
to support more tiles/segments or a greater active area of E
Ink Prism™ material than can be connected to a single
controller. In such cases, one controller acts as the system
master controller and the rest are slave controllers, operating
under the coordination of the master. Communication
between controllers uses a CAN bus connection over standard
Ethernet cabling with RJ45 connectors.

To chain multiple controllers together, use the Ethernet cables
provided with each controller, or any standard Ethernet cables
of up to 10 meters in length. (CAT6 cables are preferred.)
Connect the “OUT” connector of the first controller to the “IN”
connector of the second as shown, and so on until all required
controllers are connected.

Connect the “OUT” connector of the first controller to the “IN”
connector of the second as shown, and so on until all required

Using Ethernet cables longer than 10 meters between any
two controllers may have degrade system performance. It is
strongly recommended that no cables longer than 10 meters
are used at any point in a given installation.

When setting up a multi-controller installation all
controllers must be connected together prior to applying
power to the system and care should be taken in planning the
power distribution so that all controllers power up at the same
