Setting Up Communications between Two or More Control Units
Two-way communications between control units enables you to set up lighting and shade effects for more than one
control unit.
Depending on the room or facility, you can set up two-way communications so that all control units "talk" and
"listen" to each other. In this configuration, selecting a scene at any one of the control units automatically activates
the same scene in the others. Optionally, you set up some control units to share two-way communications while
others do not. This configuration enables you to specify which control units activate the same scenes and which
work independently.
NOTE: The control units must be addressed (as described on page 17) before setting up two-way communications.

Example: Three Control Units All Communicating for 40-Zone Control
A4
8 zones
All three control units are programmed to communicate with one another and act like a 16-zone control unit.
Note that communications are set up both ways among all control units:
• A1 "talks" and "listens" to A2 and A3.
• A2 "talks" and "listens" to A1 and A3.
• A3 "talks" and "listens" to A1 and A2.
Setting Up Communications between Control Units, Wallstations, and Other Accessories
Wallstations and other optional accessories (refer to page 3) must be set up to communicate with control units on
the GRAFIK Eye link. For procedures on how to set up communications with wallstations and accessories, refer to
the separate instructions included with the device.

To set up communications between control units:
1. Put A1 in setup mode. Press and hold the SCENE 1 and OFF buttons for
about three seconds, until the LEDs cycle.
2. Identify the control units that should "listen" to A1 (A2 and up to six
others). At each of the other control units, press and hold the SCENE 1 button
for about three seconds until the LEDs flash in unison, showing that these
control unit(s) are "listening" to A1 and will respond to its commands.
To make a "listening" control unit not listen to A1: Put A1 in setup
mode, then press the "listening" control unit's OFF button until the LEDs stop
flashing.
3. Take A1 out of setup mode. Press and hold the SCENE 1 and OFF buttons
for about three seconds, until the LEDs on A1 and all other linked control units
stop cycling.
You have set up communications in one direction between A1 and all "listen-
ing" control units.
4. To complete the two-way communication, reverse the process
described above. Put A2 in setup mode; then make A1 (and any other control
units) "listen"; then take A2 out of setup mode. Continue for each control unit.
