Before Using the Product
This section provides necessary information of the product before actual use.
About the Product
This product is an analog input terminal that sends input analog signals wirelessly in the Sub-GHz band.
*1 Data is sent to Ethernet gateway (Master) of the Wireless I/O series.
With strength against obstacles, capability of long-distance communications in the Sub-GHz band, and
mesh support, it is suitable to control or monitor devices that are spread in the wide area.
4 channels of 10-bit non-isolated analog input are equipped to support ±10V bipolar input. This product
provides excellent cost performance afforded by focusing on solely analog input function.
With the provided driver library API-AIO(WDM), you can create application software for Windows
using various programming languages supporting Win32 API functions such as Visual Basic and Visual
C ++.
*This product should always be used along with the Wireless I/O series Ethernet gateway (Master).
*Driver library can be downloaded from the Contec website.
*AI-1004LY-WQ-US can be used in the United States. AI-1004LY-WQ-EU can be used in
European countries.
*1 Sub-GHz indicates frequency bands of 1GHz and below. Available frequency band of the product
depends on the model. The AI-1004LY-WQ-EU can be used in the 868MHz band (Europe), and the
AI-1004LY-WQ-US can be used in the 915MHz band (The United States).
Features
- Supports Sub-GHz band wireless with excellent transmission distance
This product converts the input signals wirelessly in the Sub-GHz band and transmits to the gateway.
From the LAN port of a PC, analog signals (±10V) can be easily input via the gateway.
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.

INIT
This is used to initialize (restore the factory settings) the product. If
this button is pressed for three seconds or longer, LED of WLINK
starts flashing in orange. If the button is released before the
flashing stops, all the settings of the product are restored to the
factory settings after rebooting the product.
* When initializing the product with INIT button, flashing continues for a while. This indicates that files in the built-in memory are being
removed. If you turn off the power before flashing stops, the files in the built-in memory are damaged and this might prevent the product
