2.5 Configuration access with Insight PC software
Figure 5 Insight PC software configuration example: relay output A options
Indigo200 transmitters and the probes connected to the transmitters can be configured,
monitored, and calibrated by connecting the transmitter to a PC that has Vaisala Insight PC
software installed. To access the configuration options in Insight PC software, you need to
connect a computer with Insight PC software to the transmitter front cover USB port with a
USB-C (type C to A) cable. You can either use either a generic USB-C cable, or the Vaisala
accessory cable (item code: 273956). Using Indigo200 transmitters with Insight software
requires the Vaisala USB Device driver.
Note that a USB-C cable is not included in Indigo200 transmitter deliveries by
default.
Chapter 2 – Product overview
13

Note that the USB cable connection to Insight is only intended for temporary use
during configuration, and must not be used for permanent installations. The IP
rating and EMC properties of the transmitter can be aected when the USB port
is open.
For an overview of using the Insight PC software, see Insight PC software overview (page 25).
2.6 Receiving analog output settings from probe
When you take Indigo201 in use for the first time and have not entered an analog output
configuration, the transmitter automatically adapts the analog output configuration of the first
Vaisala Indigo-compatible probe you connect.
If an analog output configuration already exists in Indigo201 (that is, you have previously
connected a probe or configured the settings), you need to set the analog output
configuration of the new probe manually. Analog output from the transmitter is halted and
does not resume until you have set the new probe's configuration.
Alternatively, you can clear the analog output settings in Indigo201 configuration. This returns
the transmitter to a state where it automatically starts using the analog output configuration
of the next connected probe. For instructions, see Clearing transmitter analog output
configuration (page 30).

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 on the transmitter base as is needed to fit your cable
through the opening.
b. Lead the cable through the cut in the seal.
c. Nest the cable inside the groove on the back of the transmitter as shown in Figure 7
(page 17), and attach strain relief as needed.
To preserve the IP rating of the transmitter, the back of the
transmitter must rest flat on the installation surface. Always nest the
cable inside the groove on the back, so that the cable does not push
the back of the transmitter o the installation surface.
CAUTION!
d. If you wire only through the back, plug or seal the other lead-through on the bottom.
Chapter 3 – Installation
17

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.
