Connecting a Vaisala WXT5x0 Weather Transmitter
The Vaisala WXT5x0 Weather Transmitter is a compact, well-featured instrument that is ideal for
implementing small weather stations. The iRIS supports the connection of these units using the SDI-12
interface.
The instrument should be connected as shown below. The SDI-12 interface adaptor is omitted for clarity.
This diagram assumes the use of the optional interface cable that is provided by Vaisala. Cover the screen
wire (clear) and unused wire ends (pink, yellow and grey) heater with sleeving or heatshrink tubing to avoid
short circuits.

application.
The last subsection, (Section
