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.

Wallstation Installation
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 GRX-3000 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) or Wallstation. Connect the bare drain wires and cut off
the outside shield.
