WDR-3 is a network compatible data logger that records output voltage and ON/OFF(point of contact) signals from various type of sensors and measuring devices and with its network connection allows the user to download the measurements and data.
WDR-3, has a built in network connection function which allows the user to connect to any type of network, including the Internet for the monitoring of real time measurements; giving the user a low-cost way to monitor measurement signals in real time over great distances.
Application Examples
*For instrumentation such as flow meters, wattmeters or analyzers
*Monitoring and recording data of control devices and measurement instruments in factories.
*Collecting recorded data of analyzers for environmental indicators such as acid rain, pH, etc...
*Collecting weather data such as rainfall, snow accumulation, solar radiation, wind speed / direction etc...
*Measurement in places where wiring is difficult or impossible.
Measuring and Managing Instrument Signals
Measure and record analog signals (voltage 0 to 5V) and ON/OFF signals. Number of Channels: 2 channels for Analog Signal, 2 channels for ON/OFF Signal for total of 4 channels.
Two types of measurement method (instantaneous or average) for analog signals, as well as two types of recording method (Pulse Number or Polarity Change) for ON/OFF signals are available to be chosen from for each channel.
Via an Internet Browser it is possible to view Current Measurement Readings, Download Recorded Data
Because the WDR-3 is designed with a built-in WEB server, it can be accessed directly from a browser. Besides checking on current measurements via the browser, it is possible to view all recorded data in list form. Moreover, various communication and operational settings for the WDR-3 can be carried out via a browser.
Note: Network Settings are made using the Network Settings Utility.
Possible to Transmit Recorded Data as an E-mail Attachment to Specified Addresses at a Set Time
The WDR-3 incorporates a Data Sending function which allows for the automatic transmission at regular intervals of recorded data as E-mail attachment. This enables the receiving of recorded data at specific time intervals as set by the user.
Voltage Measurement Range: 0 to 5V
WDR-3 can measure and record input voltage from 0 to 5V. You can choose to record the voltage measurement as the instantaneous value for each recording interval span or as the average value for each recording interval span.
[Recording by Instantaneous Value]
Records measurements at set recording interval.
[Recording by Average Value]
Records the average value of the measurements taken every minute within the set recording interval.
Internet Connection allows for Global Access to Data
The built-in Web Server gives the user the option of putting the data on the Internet for global access. Also by using the Internet connection the user can escape the boundaries of the Local Area Network and gain the freedom to manage and collect data from anywhere the Internet is available. This provides the facilitation of efficient management from remote sites, as well as offering outstanding cost performance.
Set Upper / Lower Limits and Send Warning E-mail
By making upper and lower limit settings for the WDR-3, when one of the set upper or lower limits has been exceeded, warning report e-mails can be sent.
Note: To make use of the warning report e-mail send function, it is necessary to create an environment in order to connect to the Internet or to an in-company (in-house) SMTP/POP server.
Possible to Use Contact Output for Warning Occurrence
When a set upper or lower limit has been exceeded, it is possible not only to send a warning report via e-mail, but it is also possible to use the provided contact output on the main unit to issue a warning within a structured warning system.

The WDR-3 is designed solely for network communication. It does not include any RS-232 or USB communication interface. To use this product, please make sure to connect it to a network. Moreover, in order to use this product via the Internet, the user will need other devices, such as a router, and must first make necessary arrangements such as establishing an account with an Internet Service Provider for a line and obtaining a fixed IP address, domain, etc.
*1 If you already have the following wireless LAN card, please use as directed. The wireless LAN card which has been tested and proven compatible with WDR-3 is the Dark Marketing Corporation's Wireless LAN card "XI-815".The production and sales of this card have been discontinued.
When making settings in a WDR-3 without any settings already made (when purchased or after resetting), it is necessary to carry out these settings using a wired LAN connection. After having made all the necessary settings via the wired connection, it is possible to use a wireless LAN connection.
