1.0 Introduction to STS Telemetry

Solinst STS Telemetry Systems provide an economical and efficient method to access remote water data instantly. They provide two-way communication between field located dataloggers and a Home Station computer. STS Telemetry Systems are designed specifically for high quality Solinst dataloggers. Up to four Solinst dataloggers can be connected to one STS.


See the Levelogger and Vented Dataloggers User Guides for more information on datalogger specifications, operation, and deployment.

STS Systems operate on two basic schedules. A linear "Sample Rate" is set, at which the STS Remote Station records a real-time reading from each attached datalogger. A "Report Rate" is set to establish the frequency that the data is sent from the Remote Station to the Home Station Computer. Optionally, dataloggers themselves can be set up to record and store data independently of the STS System. This provides a reliable back-up if circumstances require it.

STS Telemetry Systems can be set up using 4G LTE cellular communication. Data is 'pushed' from the STS Remote Station to the Home Station using IP (Internet Protocol), and therefore, dial-up or timing issues are not a problem. The STS stores data in its memory until it has been successfully uploaded by the Home Station computer.

There is also the option to connect an RRL (Remote Radio Link) network to your STS Remote Station.

STS Telemetry Systems come with standardized hardware options and use Solinst Telemetry Software, which allows easy setup, operation, and management of data. Features such as alarm notification, diagnostic reporting and firmware updating make it easy to maintain your system, while simplifying data collection.

This manual focuses on configuration, programming, and installation of STS Telemetry Systems using cellular communications. It includes instructions for installing and using Solinst Telemetry Software to set up data collection schedules, bridge RRL networks, manage data, perform diagnostic checks, and firmware updates.
