Figure 1 Indigo 201 With and Without Display, Wireless Interface Examples
Vaisala 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 between Indigo and the probe.
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).
The Indigo 201 transmitter is designed for analog output applications: the transmitter's output options include 3 analog output channels (current or voltage) and 2 relays.

Chapter 2 – Product Overview
2.6 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.
Figure 7 Desktop and Mobile Example Views
The wireless configuration interface has two user levels. All users have view-only access (no configuration rights, not password protected), and personnel that carry out configuration tasks can log in with an administrative password that allows changing the transmitter and probe settings.
To use the wireless configuration interface to modify the settings of your Indigo transmitter and the connected probe, you must first enable the transmitter's wireless connection and then connect to Indigo with your mobile device or computer. Most major browsers (for example, Firefox, Chrome, Safari and Internet Explorer) are supported: using the most recent version is recommended.

2.7 Receiving Analog Output Settings from Probe
When you take Indigo 201 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 Indigo 201 (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 Indigo 201 configuration. This returns the transmitter to a state where it automatically starts using the analog output configuration of the next connected probe. The analog output settings can be cleared from the Settings > General menu.

1. Launch the Indigo 201 wireless configuration interface.
2. Open the Settings > General menu.
3. Go to the Reset > Clear Analog Output Settings section and select Clear.
5.4 Analog Output Overrange Behavior
The analog output of the probe has a defined behavior when the values measured by the probe are outside the scaled analog output range. At first, the output is clipped when the measurement exceeds a set limit (the measurement continues, but the output does not change from the clipped value).
When the measurement exceeds the second limit (error limit), the analog output switches to the error state defined for the output.
The same clipping and error limits are applied when the measured value drops back to the scaled range: at first the output returns to the clipped value from the error state, and then to normal output.
5.4.1 Analog Output Overrange Example
Consider a probe with 0 ... 5 V output, scaled to 0 ... 200 000 ppm (= 0 ... 20 %) CO
2
.
• When the measured CO

rises above 20 %, the output rises above 5 V.
45

level rises above 21 %CO
• If the CO

2 Parameter: The measurement that is used to control the relay.
3 Unit: Select the unit of the measurement parameter that controls the relay (for example,
% if the measurement is in %CO
2
).
4 Low Trigger Level and High Trigger Level: If you want to activate the relay above or below a single setpoint without using hysteresis, enter the same value for the low trigger and the high trigger. The Output Mode selection defines whether the relay activates above or below this value.
If you want to set a hysteresis, define the limits of the hysteresis with the low and high triggers.
5 Error State: Select which state the relay is set to when an error occurs (on, off, or remains in its current state)
47
Indigo 201 User Guide M211877EN-D
Relay State Information
When one or both relays are enabled, the relay state (active/not active) is shown on the optional display. You can also check the status of the relays in the Status view of the wireless configuration interface.
Figure 23 Relay Icons on the Optional Display (Relay A Active, Relay B Not Active)
Relay Activation Setpoint and Hysteresis
You can define whether the relay is activated when the measurement falls below a set limit
(Active below trigger level), or when the measurement exceeds a set limit (Active above
trigger level). To prevent the relay switching back and forth when the measured value is near to the setpoint value, you can set a hysteresis with the Low Trigger Level and High
Trigger Level settings.
For example, if you want the relay to activate when the measurement exceeds (Active
above trigger level) 2000 units, but do not want the relay to switch off if the measurement momentarily falls between 2000 and 1980 units, set the High Trigger Level to 2000 and
Low Trigger Level to 1980. With this configuration, the relay activates when the measurement exceeds 2000, but does not switch off until the measurement falls below
1980.
6.2 Setting Relay Activation Limit
Without Hysteresis
You can set the relay to activate when the probe measurement exceeds or falls below a set limit. When you configure a single setpoint for relay activation without hysteresis, the relay switches on or off immediately when the measurement moves over or below the setpoint
(depending on the low/high activation mode selection).
When you enter a value into a field, the value is saved automatically when you exit the input field (for example, tap on an area outside of the field).
48
Chapter 6 – Configuring Relays
To define a single setpoint for relay activation:
1. Open the Settings > Relays menu in the wireless configuration interface.
2. In the Relays menu, select the relay activation mode from the Output Mode dropdown menu: a. select Active above trigger level if you want the relay to activate when the probe measurement exceeds the set limit b. select Active below trigger level if you want the relay to activate when the probe measurement falls below the set limit
3. Select the measurement parameter that is used to control the relay with the Parameter dropdown.
4. Set the unit of the measurement parameter with the Unit dropdown.
5. Enter the same measurement limit to both the Low Trigger Level and the High Trigger
Level field.
With this configuration, there is no hysteresis. The relay activates or switches off immediately after passing this point.
6. Select the Error State for the relay.
6.3 Setting Relay Activation Limit Using
Hysteresis
If the measurement you are using to control the relay is likely to move back and forth close to the activation setpoint, you can set a hysteresis that prevents the relay switching on and off too frequently.
When hysteresis is used, the relay activates at the defined limit, but does not switch off immediately when the measurement moves back to the other side of the activation limit.
Instead, with hysteresis, the relay remains active until the measurement reaches the defined tolerated variation limit.
To set a relay activation limit with hysteresis:
1. Open the Settings > Relays menu in the wireless configuration interface.
2. In the Relays menu, select the relay activation mode from the Output Mode dropdown menu: a. select Active above trigger level if you want the relay to activate when the probe measurement exceeds a set limit b. select Active below trigger level if you want the relay to activate when the probe measurement falls below a set limit
49
Indigo 201 User Guide M211877EN-D
3. Select the measurement parameter that is used to control the relay with the Parameter dropdown.
4. Set the unit of the measurement parameter with the Unit dropdown.
5. Enter the relay activation limit either to the Low Trigger Level or the High Trigger
Level field: a. If you are using Active above trigger level (relay activation when the measurement exceeds a set limit), enter the limit to the High Trigger Level field.
b. If you are using Active below trigger level (relay activation when the measurement falls below a set limit), enter the limit to the Low Trigger Level field.
6. To define the hysteresis value: a. If you are using Active above trigger level, enter the limit for tolerated variation below the setpoint to the Low Trigger Level field.
With this option, the relay activates when the measurement exceeds the limit entered in High Trigger Level, and switches off when the measurement falls below the limit entered in the Low Trigger Level field.
b. If you are using Active below trigger level, enter the limit for tolerated variation above the setpoint to the High Trigger Level field.
With this option, the relay activates when the measurement falls below the limit entered in Low Trigger Level, and switches off when the measurement exceeds the limit entered in the High Trigger Level field.
7. Select the Error State for the relay.
6.4 Selecting Relay Error State
You can define whether the relay is switched off or on in an error state, or whether the relay remains in the state it is on the moment an error state occurs.
1. Open the Settings > Relays menu in the wireless configuration interface.
2. In the Relays menu, select the relay error state from the Error State dropdown menu: a. To set the relay to release when an error occurs, select Inactive.
b. To set the relay to activate when an error occurs, select Active.
c. To keep the relay in the same state as it was when the error occurred, select No
change.
