PRT-MNR2-DIN

Protege DIN Rail Module Network Repeater

Quick Start Guide

The Protege DIN Rail Module Network Repeater extends the
network capabilities of the Protege system by allowing modules to
connect to the system via an Ethernet connection, as well as
providing optical isolation between up to three branches of the
module network.

Using the PRT-MNR2-DIN, you can connect modules via the
RS-485 network, and the network repeater can be connected to the
controller using Ethernet. This allows much greater separation and
ease of wiring than previously possible. In addition, the network
repeater has three optically isolated RS-485 branches, easing
power supply requirements.

When receiving this product, you should find the kit contains the
items listed below. If you do not have the correct contents, please
contact your distributor immediately.

1. Power Supply

For devices using hardware revision 010, COM1 can only
be used for supplying power to the network repeater when
the module is connected via Ethernet.

The network repeater provides the connection of up to three
optically isolated RS-485 network stubs. To maintain proper
isolation, each connection requires a separate power supply.

Power to the network repeater is supplied by the N+ and N­terminals on the COM1 port and is also used for the on-board
electronics and the Ethernet connection.

It is important that the N+ module power is 12VDC supplied from an
independent battery backed power supply unit such as the
PRT-PSU-DIN capable of supplying the required voltage.

Warning:

 The 12V N+ and N- DC power input must be supplied

from only ONE point. Connections from more than one
12V supply may cause failure or damage to the
PRT-MNR2-DIN module.

 A 330 Ohm EOL (End of Line) resistor MUST be

inserted between the NA and NB terminals of the
module directly connected to the Module Network
Repeater.

The COM2 and COM3 ports are powered separately and optically
isolated from each other.

2. Encrypted Module Network

For devices using hardware revision 010, you can only use
COM2 and COM3 to create module network spurs when the
network repeater is connected via Ethernet.

The network repeater incorporates encrypted RS-485
communications technology. The isolated communications interface
offers full galvanic isolation to prevent ground loop noise and cross
phase ground differential between network devices on the three
RS-485 ports.

Standard Communication Connection

Always connect the NA and NB terminals of the network repeater to
the NA and NB terminals of the communication network. The N+
and N- must go to a 12V power supply source as shown in the
following diagram and connected at ONLY one +12V power source.

3. Ethernet 10/100 Network Connection

The network repeater can communicate with the controller via a
10/100 Ethernet connection using the encrypted UDP protocol, or
via the RS-485 module network using the COM1 port.

Ethernet communication is not enabled by default, and is configured
through the web interface.

When installing an Ethernet connection the network repeater should
be interfaced using a standard segment (<100M in length) and
should be connected to a suitable Ethernet hub or switch.

Installing the module network repeater on an active network
requires knowledge of the configuration and structure for
the network. Always consult the network or system
administrator and ask them to provide you with a fixed IP
address that can be assigned to the module network
repeater.

4. Repeater Configuration

Configuration of the network repeater is carried out using the built in
web interface. To access the web interface, open an Internet
browser (such as Internet Explorer or Mozilla Firefox) and type the
IP address of the network repeater into the address bar.

The default IP address is 192.168.1.3 and the default operator login
is admin with the password admin. For security reasons, this
password should be changed before deployment.

When attempting to view the web page from a network that
uses a Proxy Server, ensure the browser connection
options are configured to recognize local addresses.

For more information on programming the network repeater through
the web interface, refer to the full installation guide available on the
ICT Website (http://www.ict.co).
