The RTR-500NW is a network base station with built-in Wireless and LAN Communication Capabilities. The RTR-500NW can be set up to automatically download recorded data from an RTR-500 Series Wireless Data Logger via wireless communication, and then send that data via a network to an e-mail address, FTP folder or T&D’s own WebStorage server. It can also monitor for warnings and send warning reports across a network to specified addresses.

The RTR-500NW is for a wired LAN and the RTR-500AW for a wireless LAN connection.
If it is desired to view data with a web browser, the RTR-500NW can be configured to upload current readings to T&D WebStorage Service via FTP.

A Base Unit with built-in Wireless Communication and LAN Capabilities
The RTR-500NW is for a wired LAN. The RTR-500AW is for a wireless LAN.
Base Units can automatically download recorded data from a Remote Unit (RTR-500 Series) via wireless communication, then send that data via a network to any location. Range if unobstructed and direct, is about 500 ft. Range may be extended via Repeaters.

Downloading Recorded Data

The RTR-500NW/AW Base Units can be set up to carry out a chain of operations where by they periodically download recorded data and/or current readings from Remote Units (RTR-500 Series Data Loggers) and send that data via a network to an e-mail address, FTP folder or to the "T&D WebStorage Service".

By having the RTR-500NW/AW send the downloaded current readings to the "T&D WebStorage Service" it is possible to access via web browser. T&D WebStorage Service is a free web-based storage service.

To add an RTR-501/502/503/507 Remote Unit over the network, it is necessary to purchase an RTR-500 Base Unit separately.
An Array of Warning Monitoring Functions
If a measurement exceeds one of the set Upper or Lower Limits the RTR-500NW/AW will judge whether or not a warning has occurred. If a warning has occurred notification will be shown by the LED lamp and an e-mail report will be sent, the ALARM LED lamp on the RTR-500NW/AW will come on and a warning email may be sent to e-mail address(es).

External Contact Output (Warning Output)
When the "ALARM" LED lamp goes on, the external output on the RTR-500NW/AW simultaneously switched to ON.It is possible to create a foolproof warning system by connecting a siren, light or other warning device to the output terminal.

External Contact Input
By connecting a sensor such as a motion sensor, light sensor, or open/close sensor to the external input terminal of the RTR-500NW/AW it is possible to detect electric signals (ON /OFF) from outside and create a surveillance system. When an ON signal is detected an warning report mail will be sent.
Up to 100 Remote Units can be Registered

La Crosse Technologies V10-TH

The La Crosse V10-TH Wireless Weather Station (Model No. C84343) is absolutely wonderful. The setup was easy with the Quick Setup Guide provided with the unit. The packaging contains additional support information with the website and phone number if there are questions. I especially liked the daily high low readings and the color on the unit! Tech Instrumentation provided great communication as to the availability of the product and shipping details. If fact, it arrived one day prior to the estimated delivery date. I would absolutely recommend this product and Tech Instrumentation for anyone looking for an indoor/outdoor weather station!


I needed a replacement as my original sensor no longer worked. This one works fine.

Excellent Customer Service!

I can't way enough about the customer service at Tech Instrumentation. I was looking for a hard to find specialty part, which the manufacturer told me would need to be custom made. After calling and speaking with a representative at Tech Instrumentation, the part was located and order was filled, right over the phone. Delivery was prompt, and instrument is working great. Highly recommended company for lab supplies!

Worked great

Put batteries in and worked great
