Initial Network Setup

In addition to a Command Line Interpreter ("CLI"), VersaSync offers a web user interface ("Web UI") that is used to configure and monitor the unit. Described below is how to setup communication with the Web UI.

Note: VersaSync supports zeroconf: If you have a DHCP enabled network, you can use zeroconf for initial setup. For more information, see Zero Configuration Setup. Otherwise follow the instructions below for conventional setup.

Default settings:

VersaSync network settings default to DHCP, i.e. if the unit is connected to a DHCP server via ETH0 or ETH1, it will accept an assigned dynamic IP address.

In order to apply a static IP address, DHCP must be disabled, as described below. (Your network administrator will provide you with an IP address you can use for the unit.)

Setup procedure:

    1. Hardware connections

    Connections: Overview

    Requirement Action Evaluation kit cable
    Power up Connect 12 VDC to the power connector. Attach a cable and apply 12 VDC to the plug labeled "Main" (CA08R-CRPB-0002)
    USB connection Connect USB to the Multi I/O connector. Connect the USB connector to a PC with a terminal emulator program (CA08R-CRUB-0002)
    Network connection Connect at least one of the two Ethernet connectors to a network. Connect the RJ45 jack labeled ETH0 or ETH1 to a network hub/switch or directly to a PC (CA08R-CRET-0002)
    1. POWER: Connect power to the unit: If you are using the Evaluation Kit, connect the barrel connector of the 12 V transformer cable to the power cable labeled "Main". Connect the 110 V/240 V connector of the 12 V transformer to an outlet. The unit will start up (the power LED will pulsate.)
    2. USB: Connect the Multi I/O connector to the VersaSync unit. If you are using the Evaluation Kit, connect the Multi I/O USB output to a PC. Install a terminal emulator program on the PC (e.g., TeraTerm® or PuTTY®).
    3. Ethernet: Connect the Ethernet cable to the ETH port of the unit. If you are using the Evaluation Kit, connect at least one of the two I/O cable Ethernet ports (ETH0 or ETH1) to a network switch/hub, or to the PC mentioned above (using a standard Ethernet patch cable, or a crossover cable.)

    2. USB driver

    • Turn on the PC; new hardware (the USB interface) will be detected. The correct driver should be installed automatically. If not, download the driver from, and install it manually:
      • Download the driver and the instructions for your operating system (or follow the instructions below.)
      • Using the Windows Device Manager, locate the new USB hardware under Other devices, right-click on it, and select Update Driver Software…
      • Locate the downloaded driver on your local hard disk:
      • The driver will be installed:

    Network address

    1. Start the terminal emulator program on the PC. Select the COM port that is assigned to the USB interface:

      Access the CLI via ssh or telnet: The required port configuration is 115200 8N1:

      Press the Return key, and enter the login credentials:

    2. Note: The default login credentials are:
      User name = spadmin
      Password = admin123 (will not be displayed on the screen)

    3. If you are on a DHCP-enabled network, retrieve the IP address assigned to VersaSync by typing the net4 command. The command should return the network settings, including the IP address assigned to the unit. Take note of the IP address.
    4. You can use this IP address to login to the VersaSync Web UI and then set a static IP address, subnet mask and gateway (see Step 4. below).

      Or, continue with the network configuration via the CLI, as described under Step c. below.

      Note: For your reference, the command helpcli produces a list of available commands. Press the space key to display the next page, or the b key to display the previous page.

      Note: Should it become necessary to leave the VI editor mode (indicated by a command line prompt ":"), press Q, or Ctrl C.

    5. To disable DHCP type dhcp4set <x> off , (x being 0/1 for ETH0 and ETH1, respectively). Example:
    6. dhcp4set 0 off

    1. Type net4 to confirm that DHCP has been turned off. Setup a new IP address by typing ip4set <x> <IP address> <subnet mask> and –if required– gw4set <x> <gateway address>. For a table with subnet mask values, see

    Login to the Web UI

    1. On a PC connected to VersaSync via ETH0 or ETH1, start a web browser.
    2. Navigate to the IP address obtained in Step 3.b, or assigned in Step 3.d.
    3. Login to the VersaSync Web UI, using the same credentials as mentioned above.
    4. If so required, you can also change VersaSync's IP configuration (address, subnet, gateway, ...):
      1. Navigate to MANAGEMENT > Network Setup.
      2. In the Ports panel on the right, click the GEAR button next to ETH0 or ETH1: The Edit Ethernet Port Settings panel will open.
      3. Note: If you have not disabled DHCP yet, uncheck Enable DHCPv4, but DO NOT click Submit until after completing all IP configuration settings.

    5. Click Submit, and start a new Web UI session by entering the new IP address into your browser, and logging into the Web UI again.
    6. You have now established a network connection with VersaSync. Continue with other configurations e.g., NTP settings, references, outputs, etc. See the user manual:
