The TR-57DCi is a Data Collector designed to collect recorded data from data loggers (T&D Thermo Recorders and Voltage Recorders).
It can be used to gather and check recorded data on the spot without having to manually gather the data loggers. Recording settings such as " Recording Interval" and "Recording Start" can also be made directly from the TR-57DCi into the logger.
Compatible devices for use with the TR-57DCi include TR-5i Series (Infrared Communication Type), TR-5S/5 Series, RTR-500/5 Series, TR-7Ui/7U/7S Series, and VR-71 Data Loggers.

Communication Between TR-57DCi and Compatible Data Loggers
The communication method will depend upon the type of Data Logger.

Infrared Communication:
By placing the infrared port of TR-57DCi Data Collector and TR-7Ui Series, TR-5i Series Data Loggers face-to-face, it is possible to download recorded data via infrared communication.
* Infrared communication cannot be used to make recording settings or send the "Recording Start" command.
Communication & Collection examples
Optical Communication:
By using the optical communication interface of the TR-57DCi Data Collector, it is possible to collect recorded data from, make recording settings for, and start recording in TR-5i Series (Infrared Communication Type), TR-5S/5 Series, and RTR-5 Series Data Loggers.
Communication & Collection examples
Cable Communication:
By connecting the cables shown below to the serial communication cable jack on the Data Collector, it is possible to collect data from and make settings for TR-7Ui /7U/7S Series and VR-71 Data Loggers.

* There are some items for the VR-71 which cannot be set via cable communication, such as switching the unit for the unit's LCD display.
Communication & Collection examples
Connection between PC and TR-57DCi
The collected data can be easily downloaded from the TR-57DCi with a USB cable to a PC.
Communication & Collection examples
By using an optional RS-232C Serial Communication Cable (TR-07C), it is also possible to communicate with a PC via serial communication.

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
