Vaisala Indigo200 transmitters are a plug-and-play host device platform for Vaisala Indigo-
compatible probes. Indigo transmitters extend the feature set of connected probes with a
range of additional options for outputs, measurement viewing, status monitoring, and
configuration interface access.
Depending on the Indigo200 transmitter model, a display is available as an optional selection
or as a standard feature. In the non-display model, an LED indicator is used for notifications.
Probes can be connected either directly on the transmitter from the probe's connector, or by
using a cable between Indigo and the probe.
For easy access to configuration and additional monitoring options, the transmitter can be
connected to Vaisala Insight PC software with a USB cable.
The Indigo201 transmitter is designed for analog output applications. The transmitter's output
options include 3 analog output channels (current or voltage) and 2 relays.
