MICA Getting Started

1 Connecting Your MICA to Power

MICA BASIC WITH M12 A-CODED GPIO AND M12 X-CODED POWER OVER ETHERNET (POE).

MICA WIRELESS WITH M8 POWER SUPPLY.

Depending on the MICA variant your MICA can be powered using Power over Ethernet (PoE) or 24V DC.

The documentation included with your MICA explains how to connect your MICA to power and to your com-

puter.

Warning: Make sure to use an appropriate power source. Some commercially available

PoE injectors do not follow the IEEE 802.3afnorm and can damage devices like the

MICA through voltage peaks of up to 80V. If you are unsure which PoE Injector to use,

please contact your HARTING partner or

MICASupport@HARTING.com

The MICA boots automatically when connected to power and loads its web interface. During the boot se-

quence, the power LED will be illuminated in red and switch to green once the boot process is complete.

2 Logging In

2.1 Using Name Resolution

In most network environments the MICA will show up under the name listed on the type shield at the bottom

of the device. Depending on your combination of browser, operating system, and network settings, you can

log into the MICA web interface using either https://micaname or https://micaname.local.

2.2 Using the 10.10.10.10 Fall Back Address

If the MICA cannot connect to a DHCP server, for example because it is connected directly to a PC, you can

access its web interface under https://10.10.10.10. To do this, your PC needs to be in the same network seg-

ment as the MICA. You can do this, for example, by setting its IP address to 10.10.10.7 and its network

mask to 255.255.255.240.

If you have not set the MICA base system to a static IPv4 address, you can also use 10.10.10.10 to log into

a MICA that no longer shows up in a network due to some fault or misconfiguration. To engage this fallback

mode, disconnect the MICA from power, connect it directly to a PC that is not connected to an IPv4 network,

and power the MICA back on.

2.3 Connecting to a MICA Wireless for the First Time

When the MICA Wireless is initially connected to power, it starts in Access Point mode with the IP address

10.10.10.10 and WPA2 enabled. The SSID and WPA2 password are listed on the type shield on the bottom

of the MICA. Use these to connect to the MICA from your PC or tablet and to perform the initial configuration.

For more information about configuring a MICA Wireless, please refer to the MICA Wireless User Guide

available on www.harting-mica.com.

2.4 First Login

To log into your MICA for the first time, use the username admin and the password listed on the type shield.

We strongly recommend that you change the password immediately after logging in.

You can also access the MICA API documentation and some basic device information about your device (in-

cluding the serial number and MAC address) from this screen without having to log in.

Warning: Make sure to store your password in a safe place. HARTING is not able to recover lost

passwords. If you have lost your password, contact your HARTING service provider or

[email protected] for instructions how to return your MICA for a factory reset.

3 Working with Containers

All MICA applications consist of one or more LXC containers, which are small independent virtual machines.

The MICA web interface lists all installed containers and three general tools called Install, Settings, and Infor-

mation.

3.1 Starting Containers

Before you can interact with a container, it has to be started. To start a container, choose Start App from the

context menu. You can open the context menu by right-clicking a container icon or by long pressing it on a

touch screen. Once the container is active, its icon changes from gray to yellow.

3.2 Opening the UI of a Container

To open the user interface of a started container, click its icon. If the container has a web user interface, it

will be displayed in your browser. If the container does not have a web interface, an informational message

will be shown.

Stopped Container

Active Container

3.3 Stopping a Container

To stop a container, choose Stop App from its context menu. You can open the context menu by right-click-

ing a container icon or by long pressing it on a touch screen. Once the container is stopped, the icon

changes from yellow to gray.

4 MICA Network Configuration

The MICA base system can be configured using the Settings panel. All actions inside the Settings panel re-

quire admin privileges.

4.1 Basic Network Configuration

Network settings can be configured under Settings →Network. In most cases, you just need to configure the

primary network at this point and do not have to not worry about advanced settings.

4.1.1 General Settings

The MICA host name and MDNS name are set in the factory and cannot be changed in the UI.

GW&NS lets you choose which interface will be used to connect to the default gateway and nameserver. If

your MICA only has one network interface, this setting is disabled.

The currently used gateway and name servers are shown below. These settings can be changed in Inter-

face-specific configuration as described below.
