Centralized Lighting Control SystemEM-NWK-E-D-x
GRAFIK Systems
This product converts an Ethernet input
into multiple RS485 outputs. It is used to
translate instructions from a computer to
the RS485 input of a Centralized Lighting
Control System Processor Panel.
Two RJ45 10/100BaseT Ethernet jacks
are provided. The first jack is used to
connect the Network Interface to a
computer, while the second jack is a
“crossover” jack used to daisy-chain
multiple Network Interfaces together.
Model numbers are available with
different numbers of RS485 outputs:
Model Number
RS485 Outputs
EM-NWK-E-D-1* 1*
EM-NWK-E-D-4 4
EM-NWK-E-D-8 8
Each RS485 output is expected to
connect to a wall jack (NTOMX-62J) via
a cable included with the wall jack.
The wall jack then connects to
a Centralized Lighting Control System
processor panel via wiring within the wall.
* Not available in 230V version.
