Network connected data logger.
WDR-3 is a Network connected data logger that records output voltage and point of contact (On/Off) signals from various types of sensors and measuring devices.
Its network connection allows the user to download the measurements and data. Email notifications, Alarms and upper/lower limit settings are available. With its built-in web server, settings can be configured, current measurements viewed and downloaded all with an internet browser.

*Currently the only Wireless LAN card that has
been tested and proven compatible with the WDR-3 is the Dark
Marketing Corporations Wireless LAN card "XI-815. For details,
contact your local representative or dealer.
*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.
*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.
