5. Bench test / Step-by-Step guide

Before starting to work with the HW please be sure that you have a SIM card enabled for data and you have all the necessary information from the mobile operator (PIN, APN, login, passwd)

5.1. Connecting the hardware

5.1.1. Install the SIM card

Insert a SIM card into the SIM socket, use the first one. Make sure the SIM is enabled for data transmission.

There are two reasons for installing the SIM card as the first task: a) the SIM card could be damaged when inserted into the powered equipment, b) the information from SIM card are read only after a power cycle.

5.1.2. Connect the cellular antenna

Fit a cellular antenna. For details see RACOM web or contact RACOM for suitable antennas.

5.1.3. Connect the LAN cable

Connect one M!DGE Ethernet port to your computer using an Eth cat.5 cable.

5.1.4. Connect the power supply

Connect the power supply wires to the M!DGE screw terminals, ensuring correct polarity. Switch on the power supply.

5.2. Powering up your wireless router

Switch on your power supply. The STAT LED flashes for a few seconds and after 8 seconds it starts blinking to a green light. After approximately 30 seconds your router will have booted and will be ready; the STAT LED remains shining.

When the Mobile Connection is enabled the WAN LED starts blinking while connecting to the cellular network – the color (green/orange/red) represents the signal strength (excellent, medium, weak).

You’ll find the description of the individual LED states in ???.

5.3. Connecting M!DGE to a programming PC

  1. Please connect the Ethernet interfaces of your computer and M!DGE.

  2. If not yet enabled, please enable the Dynamic Host Configuration Protocol (DHCP) so that your computer can lease an IP address from M!DGE. Wait a moment until your PC has received the parameters (IP address, subnet mask, default gateway, DNS server).

    Alternative: Instead of using the DHCP, configure a static IP address on your PC (e.g. mask so that it is operating in the same subnet as the M!DGE.

    The default IP addresses are:

    • for Eth1

    • for Eth2

    The default subnet mask is for all interfaces.

  3. Start a Web Browser on your PC. Type the M!DGE IP address in the address bar:

  4. Please set a password for the admin user account. Choose something that is both easy to remember and a strong password (such as one that contains numbers, letters and punctuation). The password must have a minimum length of 6 characters. It must contain a minimum of 2 numbers and 2 letters.


    For security reasons, there is no default password.

  5. Agree to the terms and conditions. The user is now obliged to accept our end user license agreement during the initial M!DGE setup.

5.4. Basic setup

The M!DGE Web Manager can always be reached via the Ethernet interface. After successful setup, Web Manager can also be accessed via the mobile interface. Any up to date web browser can be used. Any web browser supporting JavaScript can be used. By default, the IP address of the 1st Ethernet interface is, the web server runs on port 80.

The minimum configuration steps include:

  1. Defining the admin password

  2. Entering the PIN code for the SIM card

  3. Configuring the Access Point Name (APN)

  4. Starting the mobile connection


Router M!DGE can be safely turned off by unplugging the power supply.
