The probe can be connected to Vaisala Indigo transmitters, either directly on the transmitter
from the probe's connector, or by using a cable between Indigo and the probe.
Indigo transmitters are host devices that extend the feature set of connected probes with a
range of additional options for outputs, configuration access, measurement viewing, and
status monitoring.
The selection of available additional features (for example, output and connectivity options)
varies depending on the Indigo transmitter model. Depending on the 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.
7.1.1 Wireless Configuration Interface Overview
Indigo transmitters are configured using a wireless browser-based configuration interface
(requires a mobile device or computer with IEE 802.11 b/g/n WLAN wireless connectivity). In
addition to probe and transmitter 
configuration and calibration, you can also use the
wireless interface to view measurement data and status information.

The wireless configuration interface has two user levels:
• All users have view-only access (no configuration rights, not password protected).
• Personnel that carry out 
configuration tasks can log in with an administrative password
that allows changing the transmitter and probe settings.
