1 GENERAL INFORMATION
RS485-ETH-N converts between MODBUS and Ethernet protocols and allow user to: Control and monitor serial
devices in the plant over the Internet or local area network with server mode.
Control and monitor devices, that support Ethernet-based protocols, over the serial interface with client mode.
Server Mode:
While operating in the server mode, RS485-ETH-N converts MODBUS RTU Over TCP, TCP and MODBUS ASCII
Over TCP queries that had received from the Internet or local area network to MODBUS RTU and MODBUS ASCII
queries and forwards them to serial devices. It converts the response it had received from the devices to query
protocol and sends it to the querying device (master).

Client Mode:
While operating in the client mode, RS485-ETH-N converts MODBUS RTU and MODBUS ASCII queries that
had received from the serial port to MODBUS RTU Over TCP, TCP and MODBUS ASCII Over TCP queries and
forwards them to remote devices connected to the Internet or local area network. It converts the response it had
received from the devices to query protocol and sends it to the querying device (master).

Power Input
Reset Button
ON LED
RX/TX LED
Ethernet Port
USB Port
RS485 Port
Figura 2.1: Definitions on RS485-ETH-N
U1-U2 Input:
RS485-ETH-N is powered on from U1-U2 input. 18 … 50V AC/DC must be applied.
RST Button:
Device is restarted when it is pressed.
ON LED:
When the LED color is orange, that means device is powered on from only U1-U2 input.
When the LED color is orange, that means micro-usb cable is connected to RS485-ETH-N.
RX/TX LED:
When the LED color is orange, that means device is being responded to RX query.
When the LED color is blue, that means device is being responded to TX query.
If RX/TX queries come to RS485-ETH-N rapidly, RX/TX LED color can be seem as white.
ON LED & RX/TX LED:
If two of them blink at the same time, it means that RS485-ETH-N is restarted.
Ethernet Port:
Ethernet cable must be inserted.

USB Port:
Micro-USB cable must be inserted to this port. Device can power on with USB port as well. If
operator wants to use WEG GATEWAY MASTER must be connected to PC over micro-usb cable.
RS485 Port:
It provides to communicate with the devices that support Modbus Protocol.
2.2 CONFIGURING RS485-ETH-N
There are three options when RS485-ETH-N is configured.
1. Using WEG GATEWAY MASTER software over USB port. (Will be explained in “Section 3”).
Figura 2.2: Gateway Master Software
2. Writing RS485-ETH-N IP address to the WEG GATEWAY MASTER. (Will be explained in “Section 4”).

3. Writing RS485-ETH-N IP address to the Web browser. (Will be explained in “Section 4”).
Figura 2.4: RS485-ETH-N Web interface
NOTE: In order to access RS485-ETH-N web interface; operator should change RS485-ETH-N default IP and
other related settings with using WEG GATEWAY MASTER software.
2.3 REQUIRED INSTALLATIONS FOR CONFIGURATION SOFTWARE
In order to configure RS485-ETH-N over USB port, required installations will be explained in this section.
Operator can find necessary files in the CD that is in product box.
Setup=>WEG GATEWAY MASTER.exe must be installed for RS485-ETH-N configuration software.
2.3.1 Installing RS485-ETH-N Configuration Software
Run WEG GATEWAY MASTER.exe which resides in the CD that comes with the product.
After selecting the desired target where software will be setup, click on the “Next” button and continue with the
next step.
