Sample One-Line
RS-485 Network
Connect up to 254 ControlKeeper lighting control panels and accessories
1. Daisy-chain all ControlKeeper lighting control panels using twisted pair
(Belden #9841) or category 5 cable.
2. Lighting control network up to 4000 feet total length. If greater length is
needed RS-485 repeaters are available.
Lighting control panel power supply:
Voltage specific transformer. Specify 120 VAC or 277 VAC
for the transformer voltage.
GDS network uses
a GDS-I-KIT to access
the panel.

The Ethernet Interface Module (EIM) and
Wireless Ethernet Interface Module (WEIM)
may be connected to any lighting control panel
in the system using the RS-232 cable included
2 low voltage inputs
(Momentary, Maintained, Alternate Action
switches, occupancy sensors and Photocells)
Each input is software programmable to
control any relay or group of relays
120 VAC wall transformer included
End user computers
can program any lighting control
panel via the Wireless Ethernet Interface Module (WEIM)
using the Keeper Enterprise software.
