6.7 Connecting a Vaisala WXT510 Weather Transmitter (iRIS 320 only)

The Vaisala WXT510 Weather Transmitter is a compact, well-featured instrument that is ideal for implementing small weather stations. The iRIS 320 / iRIS 320V models support the connection of these units using the SDI-12 interface.

NOTE: Although the standard iRIS software only supports six sensors, it allows a special exception when using the WXT510, which provides seven parameters. To achieve this, hail measurements are logged as a “secondary” sensor linked to rainfall, (which must be configured as sensor 6). Hail is logged with an array ID of 10 and it shares the same logging configuration as rainfall (logging rate, event mode etc). The hail “sensor” is not visible from the LCD or terminal sessions.

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 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.
