2. Product overview
2.1 Introduction to Indigo300 transmitter
16.03.2022
Figure 1 Indigo300 connections overview
Vaisala Indigo300 Transmitter is a host device for displaying measurement values from Vaisala
Indigo-compatible probes and/or transmitting them to automation systems through analog
signals.
Probes can be connected to the transmitter tool-free using the locking wheel. You can connect
a probe to the locking wheel directly or by using a cable. Instead of the locking wheel, it is also
possible to use a cable gland with a fixed cable.
The service port on the front can be opened with a 4-mm Allen key for enabling access to the
free Vaisala Insight PC software or Indigo80 handheld indicator.
With Insight and Indigo80, you can configure both the transmitter and the probe connected to
it, as well as calibrate and adjust the probe without having to detach it from the transmitter.
2.1.1 Indigo300 basic features and options
• All Vaisala Indigo-compatible probes can be connected to all Indigo transmitter models
• Numerical and graphical color display for up to 3 parameters
• Support for one Indigo-compatible probe
• Power supply input 15 ... 30 V DC (24 V AC ±10 % 50/60Hz)
• 3 pre-configured analog outputs (mA or V)
• Service port on the front for connecting to Vaisala Insight PC software or Indigo80
handheld indicator
• 1-m, 3-m, 5-m, and 10-m probe connection cables available as accessories

3Active connection to Insight PC software or Indigo80 handheld indicator
You can configure the transmitter display to show 1 to 3 measurement parameters in numeric
and graph format. Notifications, warnings and errors are shown on a message row on the top
part of the display.
The displayed parameters, display brightness, and display mode (numeric or graph) can be
configured with the Insight PC software or Indigo80 handheld indicator.
By default, the display shows the output parameters configured for the transmitter's analog
outputs. If no output parameters have been configured for the analog outputs, the display
shows the preferred parameters of the connected probe.
Switching between display views and turning display o and on
To switch between dierent display views, push the left button on the front cover once.
To turn the display o and on, keep the left button pressed down for a few seconds. You can
also turn the display o with the Insight PC software or Indigo80 handheld indicator. When the
display is o, the LED status indicator lights up to inform about the device status.

You can set the transmitter display to show the connected probe's measurement data as
graphs.
The measurement parameters and the graph time scale can be configured with the Insight PC
software or Indigo80 handheld indicator.
You can switch between the dierent display views with the push button on the
front of the transmitter.
2.3.2 Device status mode
The rightmost display view shows the status of the transmitter and the connected probe. Any
active notifications, for example, about the probe's calibration having expired, are shown. In
addition, the view shows the mode, scaling, and output value of the transmitter's analog
outputs.
To navigate to the device status view, press the push button on the front of the transmitter
repeatedly. The view is shown for 1 minute, after which the display automatically reverts to the
numeric view.
