RLE Protocol Converter Quick Start - Manual (Page 2)

Modbus EIA-485 Connections
The Protocol Converter can function as a Modbus master or Modbus slave over
an EIA-485 hardware connection. The base Protocol Converter has one 2-wire
EIA-485 connection. The dual port Protocol Converter has two 2-wire EIA-485
connections and one 2- or 4-wire EIA-485 connections for extended Modbus
polling over multiple trunk lines.
Set the IP Address Using a Web Browser
The Protocol Converter will not communicate over your network the first time it
is connected. Since it is shipped with a default IP address of 10.0.0.188, you’ll
need to change the default IP address to one that will allow it to communicate
over your network. To If you have not set an IP address before, consult your IT
Department for support.
Note: The default IP address for the Protocol Converter is 10.0.0.188
The default Subnet Mask is 255.255.255.0
The default user name is fds (all lowercase)
There is no default password - leave the password field empty.
1. Contact your IT Department to obtain an available IP address, Subnet Mask,
and default Gateway.
2. Plug a crossover network cable (provided) into the laptop or workstation that
will be used to configure the Protocol Converter.
3. You’ll need to change the IP address and Subnet Mask of your computer so it
can communicate with the Protocol Converter in its factory-configured state.
Before you change anything, write down the original IP address and Subnet
Mask of your computer - you’ll need to revert back to these original settings
once the Protocol Converter is configured.
4. Change the IP address and Subnet Mask of the computer from its existing
address to one that will allow it to communicate with the Protocol Converter,
such as 10.0.0.189. It may be beneficial to set the IP address to one that is
one number different from the Protocol Converter’s IP address (10.0.0.188).
5. Connect the other end of the crossover cable to the Ethernet port on the
back of the Protocol Converter.
6. Access the Protocol Converter through a web browser — type the Protocol
Converter’s IP address (10.0.0.188) into the location bar. When prompted,
enter the Protocol Converter’s user name, which is fds. There is no default
password, leave it blank.
7. Select the Configuration link from the top menu bar, then select the Network
and web option that appears in the Configuration Menu on the left side
of the screen. Change the Protocol Converter’s IP address, Subnet Mask,
and default Gateway to the one provided by your IT Department. Press
the Submit Changes button. The Protocol Converter will save the new IP
address, Subnet Mask and default Gateway and reboot.
8. Change the IP address of the computer back to its original IP address. If the
computer was configured as DHCP (the network domain controller assigns an
IP address) return it to this state. This may require assistance from your IT
Department, or you may need to consult the computer’s manual.
9. The computer and the Protocol Converter are now both configured to
communicate on the network. Both should be accessible via the network.
Connect the PC and the Protocol Converter to the network. From the PC web
browser, type in the new IP address of the Protocol Converter. Enter the user
name and password as stated above to verify network access to the device.
Complete the Configuration
Once the Protocol Converter has been hardwired and the IP address has been
set, it’s ready to be fully configured. It will be able to communicate over a
network and through it’s communication ports, but you will still need to perform
additional tasks to configure the devices connected to the Protocol Converter.
Access the web interface and the complete Protocol Converter user guide -
available at www.rletech.com - to complete the configuration.
