Assigning a New Static IP Address

To configure a SecureSync unit that has not yet been assigned a custom IP address (e.g., because your network does not support DHCP), there are two ways to enter the desired static IP address, subnet mask, and gateway address:

  • The front panel keypad and its 4-line information display, or
  • a personal computer, connected to the SecureSync unit via a serial cable, or via a dedicated Ethernet cable.

The keypad is the simplest method to configure the network settings. See Front Panel Keypad, and Display for information on using the keypad.

Note: Units are shipped with the default IP address of with subnet mask

Setting Up an IP Address via Serial Cable

The serial port can be used to make configuration changes (such as the network settings), retrieve operational data (e.g., GNSS receiver information) and log files, or to perform operations such as resetting the admin password.

For this task, you will need a serial cable, and a Personal Computer (PC) with a command-line user interface program (CLI) installed on it, such as TeraTerm®, PuTTY®, or similar.

To configure an IP address via the serial port:

  1. Connect a pinned straight-thru standard DB9M to DB9F RS232 serial cable to a PC running PuTTY, Tera Term, or HyperTerminal, and to your SecureSync.

    Use the following protocol parameters:

    • Bits per second: 9600
    • Data bits: 8
    • Parity: None
    • Stop bits: 1
    • Flow control: None

    For more information on using the serial port connection, see Setting up a Terminal Emulator.

  2. The serial port is account and password protected. Login to SecureSync with a user account that has “admin” group rights, such as the default spadmin account (the default password is admin123).

    Note: Users with “administrative rights” can perform all available commands. Users with “user” permissions only can perform get commands to retrieve data, but cannot perform any set commands or change/reset any passwords.

  3. Disable DHCP, type: dhcp4set 0 off <Enter>.
  4. Note: If your SecureSync is configured with an Ethernet option card, use 0, 1, 2, 3 for eth0 – eth3.

    Note: For a list of CLI commands, type helpcli, or see CLI Commands.

  5. Configure the IP address, subnet mask, and gateway (if needed):
    • ip4set 0 x.x.x.x y.y.y.y <Enter>
      (where 0 is the desired interface, “x.x.x.x” is the desired IP address for SecureSync, and “y.y.y.y” is the full subnet mask for the network (For a list of subnet mask values, see Subnet Mask Values.)
    • Enter gw4set 0 gw_address, using your gateway address gw_address.
  6. Once you have configured SecureSync's IP address, you can login to the Web UI by entering the new address into a web browser‘s address bar.

Setting Up an IP Address via Ethernet Cable

Note: You may use an Ethernet crossover cable, but you do not have to.

Turn on the unit with NO cable plugged into the Ethernet port yet (Note: once you apply power, it may take up to two minutes for the system to fully boot).

Configure your PC‘s network interface card (NIC) with an IP address on the same network as the NetClock 9489‘s default IP address ( For example, configure the IP address of your PC‘s network interface card as, with a subnet mask of

Connect an Ethernet cable from your PC to the Ethernet port of the NetClock unit. Once connected via crossover cable, open a web browser and enter the NetClock‘s default IP address ( into the browser‘s address bar and login to the NetClock‘s Web UI as an administrator. Once logged in, network settings for the NetClock can be configured under MANAGEMENT > Network Setup > Actions: General Settings and under Ports: GEAR button.
