See Figure 23 for typical RS-485-to-Ethernet network using
a EIM network access device.
Figure 23. Ethernet to RS-485
Configuring the EIM with a unique IP address, subnet
mask and IP gateway is required before establishing
communications with the Ethernet network. Consult
factory for information.
The EIM includes the following features:

Network time and location synchronization

250 Global Time Schedules

30 Holidays

Global Alarm Table
The EIM comes in a desktop enclosure and is connected to
Ethernet and PRC RS-485 networks. A personal computer
with PRC software can be located anywhere on the
Ethernet network. The EIM will communicate at 10Base-T
and must have a fixed IP address assignment on the
Ethernet network. On the front of the EIM are connectors
for CAT5, a removable RS-485 network connection (Belden
3105A network cable), and a 4-pin network diagnostic
connection for local access to the device. The EIM is
powered by using the provided +15 Vdc power supply that
plugs into any standard wall outlet. It also has an On/Off
switch, power indicator LED and communication indicator
LED. Pow-R-Command Lighting Optimization Software
(PRCLOS) is required to access the system.
Ethernet network
The PRC1500E and PRC2000E controllers are connected to
an Ethernet network by using the RJ-45 connector located
in the low voltage compartment. See Figure 24.

See Figure 25 for a typical Ethernet network architecture.

ote: N Configuring the controller’s network parameters are
required before establishing communications over
the network.
Controller configuration can be accomplished by using the
following methods:

Optional backlit color LCD touchscreen display (refer to
“LCD touchscreen display programming” on page 17)

Personal computer direct connection to controller
Maintenance Port (refer to “Connecting personal
computer to controller Maintenance Port” section
on page 15
Once the controller is configured with required network
parameters, a personal computer on the network can
establish communications with the controller.
