Figure 1 Probe Connection Options and Wireless Interface Examples (GMP251 Example)
Vaisala Indigo 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.
Indigo-compatible probes can be connected either directly on the transmitter body or using
a probe cable. The configuration interface of Indigo transmitters is a browser-based wireless
UI that requires a mobile device or computer that supports wireless connectivity (IEEE
802.11 b/g/n WLAN).
1.1.1 Indigo 202 Basic Features and Options
• All Vaisala Indigo-compatible probes can be connected to all Indigo transmitter models
• Wireless configuration interface: connect to the scalable browser-based UI of Indigo
202 to change probe and transmitter settings, view measurements, and review probe
and transmitter status
• 3.5” TFT LCD color display
• Power supply input 15 ... 30 VDC (24 VAC +/-10% 50/60Hz)
• Digital output: RS-485 Modbus RTU
• 2 configurable relays
• 1 m, 3 m, 5 m and 10 m probe connection cables available as accessories

1.4 Wiring Options
You can wire an input/output cable either through the opening on the back of the
transmitter, or through the rubber lead-through on the bottom of the transmitter.

Ø 7 ... 8 mm
Figure 3 Indigo Wiring Options
1Wiring from the back: cut the seal open
2Wiring through the rubber lead-through on the bottom of the transmitter
1. To wire the input/output cable through the back of the transmitter:
a. Cut o as much of the seal as is needed to fit your cable through the opening.
b. Lead the cable through the opening and attach a strain relief as needed.
c. If you wire only through the back, plug or seal the lead-through on the bottom.
2. To wire the input/output cable through the rubber lead-through on the bottom:
a. Push the input/output cable through the lead-through.
b. The lead-through provides strain relief and holds the cable in place. Tightening is not
required.
The recommended cable diameter for wiring through the rubber lead-through is
7 ... 8 mm. If you use a dierent cable size, test that the strain relief works as
intended.

1.5 Opening and Mounting
To avoid damaging the connector pins of the transmitter, pull the
transmitter cover o the base in a straight angle. Do not twist or bend.
CAUTION!
1. Loosen the 4 screws on the transmitter cover.
2. Carefully open the transmitter cover part of the way from both sides so it is easier to
pull the cover o the base.
3. Pull the transmitter cover o the base in a straight angle. Do not twist or bend.
4. Place the transmitter base on the installation surface and mount it with 3 screws. See
the screw positions in Figure 4 (page 10).
5. Lead the input/output cable inside the transmitter (see Wiring Options (page 8)). If you
are wiring through the lead-through on the bottom of the transmitter, test that the
strain relief works with your cable.
6. Connect the input/output cable's wiring to the screw terminals (see Indigo Transmitter
Base (page 10)) and reattach the cover when done.
