3. Step-by-step guide

3.1. Connecting the hardware

Before installing a RipEX2 network in the field, a bench-test should be performed in the lab. The RipEX2 Demo case is great for this as it contains everything necessary: 3 RipEX2’s, Power supply, dummy load antennas, etc.

If you use your own installation for lab tests, don’t forget:

  • A dummy load or an actual antenna with 50 ohm impedance should be connected to the RipEX2

  • The minimum RF output must be set to avoid overloading the dummy antenna and to keep the received signal at reasonable level, between -40 and -80 dBm.

  • The power supplies must meet the requirements given in the specifications. Make sure the power supplies do not generate interference in the radio channel and that they can handle very fast changes in the load when RipEX2 switches from reception to transmission and back.

3.2. Powering up your RipEX2

Switch on your power supply. LED SYS shines orange and after approximately 20 seconds your RipEX will have booted and will be ready, the SYS LED shines green. You’ll find the description of the individual LED states in Section 1.3, “Indication LEDs”.

3.3. Connecting RipEX2 to a programming PC

To configure a RipEX2 you can connect it to your PC in three ways:

  1. Using the external Wifi adapter

  2. Using the external ETH/USB adapter

  3. Directly over the Ethernet interface

1. Connecting to a PC over WiFi

2. Connecting to a PC over ETH/USB adapter.

3. Connecting to a PC over ETH.

  1. PC connected via Wifi adapter

    We recommend using the “W1” – external Wifi adapter (an optional accessory of the RipEX2). Connect your PC or tablet or smart phone to RipEX2 Wifi AP first. Its default SSID is “RipEX2 + Unit name + S/N”. The W1 contains a built-in DHCP server, so if you have a DHCP client in your PC (as most users do), you don’t need to set anything up. The RipEX2’s IP address for access over the ETH/USB adapter is fixed: 10.9.8.7.

    Go to Login to RipEX.

  2. PC connected via ETH/USB adapter

    We recommend using the “XA” – external ETH/USB adapter (an optional accessory of the RipEX2). The ETH/USB contains a built-in DHCP server, so if you have a DHCP client in your PC as most users, you don’t need to set anything up. The RipEX2’s IP address for access over the ETH/USB adapter is fixed: 10.9.8.7.

    Go to Login to RipEX.

  3. PC connected directly to ETH port

    Set a static IP address in PC, example for Windows XP:

    Start > Settings > Network & Internet >Ethernet > Change adapter options > Ethernet (right click)
     > Properties > Protocol IP version 4 (TCP/IPv4) > Properties > Use the following IP address:
    IP address 192.168.169.169 – for RipEX in the default state
    Subnet mask 255.255.255.0
    Default gateway leave empty
    OK (Internet Protocol Properties window)
    OK (Local Area Properties window)
    Some Operating systems may require you to reboot your PC.

    [Important]Important

    When you change the RipEX2 ETH address from the default value later on and the new IP network does not include the default one, you will have to change your PC’s static IP again to be able to continue configuring the RipEX2.

  4. Login to RipEX2

    Start a web browser (Mozilla Firefox, Internet Explorer – JavaScript enabled) on your PC and type the RipEX’s default IP in the address line default IP address in the address line field:

    • 10.9.8.7 – when connected via external ETH/USB or Wifi adapter. IP address 10.9.8.7 is fixed and cannot be changed; it is independent of the IP address of the RipEX’s Ethernet interface.)

    • 192.168.169.169 – when connected directly to ETH

    [Note]Note

    https – For security reasons the http protocol with ssl encryption can be used for the communication between the PC and RipEX. The https protocol requires a security certificate. You must install this certificate into your web browser (Mozilla Firefox, Internet Explorer). The first time you connect to the RipEX, your computer will ask you for authorisation to import the certificate into your computer. The certificate is signed by the certification authority Racom s.r.o. It meets all security regulations and you need not be concerned about importing it into your computer. Confirm the import with all warnings and exceptions that your browser may display during installation.

    The login screen appears.

    The default entries for a new RipEX are:

    User name: admin

    Password: admin

    Warning: Before you start any configuration, make sure only one unit is powered ON. Otherwise, a different radio modem could reply to your requests! (All units share the same IP address and are in Bridge mode when in factory settings.)

  5. IP address unknown

    If you don’t have the adapter or you have forgotten the password, you can reset the access parameters to defaults, see Section 1.2.9, “HW button”.
