2.1 Introduction to Indigo™ Transmitters
Figure 1 Probe Connection Options and Wireless Interface Examples (GMP251 Example)
V
aisala Indigo transmitters are a plug-and-play host device platform for Vaisala Indigocompatible 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 Indigo 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 be
tween Indigo and the probe.
The configuration interface of Indigo transmitters is a browser-based wireless UI that
r
equires a mobile device or computer that supports wireless connectivity (IEEE 802.11 b/g/n
WLAN).
The Indigo 202 transmitter is designed for digital output applications. The transmitter's
output options include RS-485 Modbus RTU and 2 programmable relays.
For more information on Indigo transmitter models, see www.vaisala.com/indigo.

our probe is compatible with Indigo, check the serial number on the probe body. All probes
intended for use with Indigo manufactured from 2017 onwards (serial numbers starting with
the letter N or latter in alphabetical order) have full compatibility.
