2. About the Product

This product is an Ethernet gateway that converts Ethernet into wireless in the Sub-GHz band*1.

Data from the Wireless I/O series terminal (Slave) can be sent to a PC via Ethernet, or received data

from PC can be sent via Ethernet.

With strength against obstacles, the long-distance communications enabled by wireless Sub-GHz

band, and multi-hop support, it is suitable to control or monitor devices that are spread in the wide

area.

By using a driver library appropriate to the setting terminal, applications can be created with API

functions that support programming languages.

This product also supports Modbus TCP Slave, which makes it possible to control devices and collect

data from the higher communication devices containing Modbus Master function.

* Driver library can be downloaded from the CONTEC website.

* The GW1-ETH-WQ-US can be used in the United States. The GW1-ETH-WQ-EU can be used in

European countries.

* Refer to “Appendix(Page48) “ for Modbus TCP Slave specification.

*1 Sub-GHz indicates frequency bands of 1GHz and below. Available frequency band of the product

depends on the model. The GW1-ETH-WQ- EU can be used in the 863 - 870MHz band (Europe),

and the GW1-ETH-WQ-US can be used in the 902 - 928MHz band (The United States).

3. Features

 Supports Sub-GHz band wireless with excellent

transmission distance

This product converts Ethernet (wired LAN) communication into Sub-GHz.

The Sub-GHz, with the good wraparound characteristics of radio waves, the transmission distance (about 1 km) can be extended even

there are obstacles. Stable communication can be achieved even in the environment where radio waves are mixed. As the product is

suitable for long distance communication, network can be constructed on the wide area in the facilities without cable wiring.

 Highly reliable mesh communication

With wireless mesh technology, the communication continues by changing the routes automatically even when disconnection occurs,

for example. Communication stability enables the wireless network to be strong against obstacles

 Modbus TCP Slave support

Modbus is a communication protocol widely adopted in the industrial field. It is possible to control devices and collect data from the

higher communication devices containing Modbus Master function.

 Adaptable to a wide range of temperature

This product is capable of operating in the temperature between -20 and + 60°C. It can be installed in the various environments.

 Compact design

Compact design, 62.0(W) x 64.0(D) x 24.0(H)mm features flexibility in installation.

 Easy mounting on DIN rail

This product can be mounted on DIN rail with an optional fixing bracket.

 Capable of adapting a wide-range power

This product is capable of dealing with a wide range of power in the differing environments.

 Work with various systems

Set the appropriate terminal (slave) with the product to work with the various systems.
