 Note that mounting the controller (or specifically the 

master controller, in a multi-controller system) inside a metal 
enclosure or cabinet may interfere with the operation of the 
Bluetooth link.  

 

7.  Connecting E Ink Prism™ Tiles to the 

Controller 

Each controller provides 128 outputs, each of which can be 
used to drive one single-segment E Ink Prism™ tile or one 
segment of a multi-segment tile. (Do not connect more than 
one tile or segment to any single output.) These outputs are 
organized into three groups. The first, located in the central 
area of the controller front panel and numbered 1 through 96, 
are referred to as the “high-density” (HD) outputs. These are 
used to drive smaller tiles/segments not requiring “wave” 
transitions. Each HD output is capable of driving a maximum 
area of 0.2 m

 (2.1 ft

), “flash” transitions only. 

The other two groups are the “high current” (HC) outputs, 
located on either side of the central HD block (see the diagram 
on pg. 8). There are a total of 32 HC outputs, with the left-hand 
group numbered 100-116 and the right-hand group numbered 
117-132. (Note that numbers 97-100 are unused.)  Each of 
these outputs is capable of driving a maximum area of 2.5 m

(26.9 ft

) in the flash transition mode. Wave transitions are 

also supported using the HC outputs, but this mode requires 
two outputs for each tile or segment. The total area supported 
is approximately the same for the wave transition mode, but 
there are additional restrictions on the aspect ratio of the tile if 
it is to be driven in this manner. The HC outputs support

15.  LED Indicators 

The controller provides two LED indicators on the front panel 
that are used to communicate system status. See the table 
below for the meanings of these indicators.

Critical error; the system cannot run normally. There 
are a number of conditions which can cause this state; 
if a critical error is reported by any controller, use the 
Prism Design Studio™ software to access the system 
log files in order to determine the specific nature of 
the fault.

In a multi-controller system, the master controller will 
have its yellow LED on continuously.
