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. 
 
 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
