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 unit, Power supply, dummy load antennas, etc.

If you use your own installation for lab tests, do not 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.

Bench test connection possibilities:

RipEX2 connected to SCADA center

3.2. Powering up your RipEX2

Switch on your power supply. LED SYS shines orange and after approximately 30 seconds your RipEX2 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:

  • Using the external Wifi adapter

  • Using the external ETH/USB adapter

  • Directly over the Ethernet interface

  • PC connected via Wifi adapter

    External Wifi adapter PartNo OTH-USB/WIFI-W2 (an optional accessory of the RipEX2) needs to be used. Any other adapter will not work correctly when connected to RipEX2 unit. Connect your PC, tablet or smartphone to RipEX2 Wifi AP first. Its default SSID is “RipEX2 + Unit name + S/N”. By default, the WPA2 PSK secured connection with password “123456789” is used. The Wifi adapter contains a built-in DHCP server, so if you have a DHCP client in your PC (as most users do), you do not need to set anything up. The IP address of RipEX2 unit, for access over the ETH/USB adapter, is fixed: 10.9.8.7.
    Continue to Login to RipEX2.

  • 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 do not need to set anything up. The IP address of RipEX2 unit, for access over the ETH/USB adapter, is fixed: 10.9.8.7.
    Continue to Login to RipEX2.

  • PC connected directly to ETH port

    Set a static IP address in PC, example for Windows 10:

    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 192.168.169.250 – for RipEX2 in the default state (for all ETH interfaces)  
    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 to a different IP address/mask, the IP address of your PC might be necessary to be updated to match the same subnet (mask).

  • Login to RipEX2

    Start a web browser (supported web browsers: Section 6.1, “Supported web browsers”) on your PC and type default IP of RipEX2 unit 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.

    • 192.168.169.169 – when connected directly to ETH. This is the default IP address which can be changed later on – during the unit configuration process.

    [Note]Note

    https – For security reasons the http protocol with ssl encryption can be used for the communication between the PC and RipEX2. The https protocol requires a security certificate. You must install this certificate into your web browser. The first time you connect to the RipEX2, 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 to 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 RipEX2 are:

    User name: admin

    Password: admin

    [Warning]Warning

    Before you start any configuration, make sure only one unit is powered ON. Otherwise, a different radio modem could reply to your requests! (In default settings: all units share the same IP address and are in Bridge mode – which means, they can connect together over the air and create unwanted responds.)

  • IP address unknown

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