Setting Up an IP Address via the Serial Port

NetClock's front panel serial port connector is a standard DB9 female connector. Communication with the serial port can be performed using a PC with a terminal emulator program (such as PuTTY or TeraTerm) using a pinned straight-thru standard DB9M to DB9F 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.

The serial port is account and password protected. You can login via the serial port using the same user names and passwords as would be used to log into the NetClock Web UI. Users with “administrative rights” can perform all available commands. Users with “user” permissions only can perform “get” commands that retrieve data, but cannot perform any “set” commands or change/reset any passwords.

To configure an IP address via the serial port:

  1. Connect a serial cable to a PC running PuTTY, Tera Term, or HyperTerminal, and to your NetClock. For detailed information on the serial port connection, see Setting up a Terminal Emulator
  2. Login to NetClock with a user account that has “admin” group rights, such as the default spadmin account (the default password is admin123).
  3. Disable DHCP, type: dhcp4set 0 off <Enter>.
  4. Note: If your NetClock 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 and subnet mask, type:
    • 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 NetClock, and “y.y.y.y” is the full subnet mask for the network (For a list of subnet mask values, see Subnet Mask Values.)
  6. Configure the gateway by typing gw4set 0 z.z.z.z<Enter>
    (where 0 indicates which interface routing table to add the default gateway for, and “z.z.z.z” is the default gateway address).
  7. Note: If your NetClock is configured with an Ethernet option card, use 0, 1, 2, 3 for eth0 – eth3.

  8. Remove the serial cable, connect NetClock to the network, and access the Web UI, using the newly configured IP address. (For assistance, see Accessing the Web UI)

The remainder of the configuration settings will be performed via the Web UI (accessed via an external workstation with a web browser such as Firefox® or Chrome®).
