WDR-3 WEB NETWORK DATA RECORDER
 
WDR-3 Web Network Data Recorder.

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.


 

  • Measure and Record Analog and On/Off Signals

  • View and Download Measurement Readings
    using Internet Browser

  • Transmit Recorded Data via Email at Set Intervals

  • Access to recorded Data and Readings via LAN, Internet or Email

  • Establish Upper and Lower Limits and Send Warning Emails

  • Connect to Wireless LAN via CF Card

Recording Method
Pulse Recording Method : Records the number of pulses during the set recording interval
(number of rising signals)
Polarity Change Recording Method: Records the time when a rising/falling signal occurs

Recording Interval
Pulse Number Recording Method: Six intervals to select from: 10,20,30,40,50 60 minutes

Polarity Change Recording Method: Measurement occurs every second without regard to
recording interval and the date and time of any change is recorded.

*Currently the only Wireless LAN card that has been tested and proven compatible with the WDR-3 is the Dark Marketing Corporation’s 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.
