Overview
The KTA-282 Modbus TCP Weather Station Gateway allows the easy connection of a PLC (Programmable Logic
Controller), RTU (Remote Telemetry Unit) or SCADA System to a Davis Instruments Weather Station. Using the
Modbus RTU (Binary), or Modbus TCP/IP (Ethernet) protocols, it enables a programmable controller to monitor and
carry out actions based on wind speed, wind direction, temperature and many other weather based variables.
The KTA-282 Modbus TCP Weather Station Gateway is a major upgrade to our popular GWY-141 Modbus-
VantagePro2 Gateway. It provides all the functionality of the GWY-141, with the following improvements:

Addition of Ethernet:
o
Allows the KTA-282 to be polled by up to three Modbus TCP/IP masters simultaneously
o
Provides a webpage whereby TCP/IP settings can be easily monitored and altered. Also shows
current settings, weather data, and communications statuses.
o
Can be interrogated over HTTP to return Modbus register values in XML format

Allows all 125 registers to be polled at once – previously limited to 30.

Supports the new LOOP 2 command in compatible devices 1 (VantagePro 2 firmware V1.90 or later, and
Vantage Vue). This provides an additional 16 packets of previously unavailable weather data.

Provides a method to setup the weather station for first use, without the need to connect it to your PC.
Notes: 1. The Weatherlink cable can be used to update the firmware of your weather station; allowing it to respond
to the loop 2 command.
