DIP Switches
• Set DIP switches 1-4 to give the Wallstation
a unique system address from 1 to 16.
• Set additional DIP switches (if any) to specify
function as shown on the first page of the
Wallstation’s Specification Submittal.

Low-Voltage Class 2 (PELV) Wiring
• Use low-voltage Class 2 (PELV) wiring to daisy-chain
Wallstations to Control Units and other components.
• Make connections inside the wallbox or in a
switch/junction box with a maximum wire length of 8
feet (2.5m) from the link to the Wallstation.
Note: EGRX Wallstations have a “D” terminal for Drain.
Connect the Drain/Shield at this terminal.
When used with GRAFIK Eye 3000 Control Units:
• Two #18 AWG (1.0mm
2
) conductors for common
(terminal 1) and 12 V Direct Current (terminal 2). Ensure
that the terminal 2 connection is wired correctly. Refer
to GRAFIK Eye 3000 Series Specification Submittal.
• One shielded, twisted pair #18 AWG (1.0mm
2
) for data
link (terminals 3 and 4).
When used with GRAFIK Eye 4000 Control Units:
• Two #12 AWG (2.5mm
2
) conductors for common
(terminal 1) and 24 V Direct Current (terminal 2). These
won’t fit in terminals. Connect as shown.
• One shielded, twisted pair #18 AWG (1.0mm
2
) for data
link (terminals 3 and 4).
• Connect Drain/Shield as shown. Do not connect to
Ground (Earth). Connect the bare drain wires and cut
off the outside shield.
