Configuring TCP/IP settings

The TCP/IP Configuration step assigns an IP address to the controller. The TCP/IP object in the Nav Container View allows you to review and adjust the platform’s TCP/IP settings.

You are running the Commissioning Wizard or updating the TCP/IP properties after commissioning.
  1. At the TCP/IP Configuration step, the TCP/IP Configuration view opens.


  2. Review the Interface 1 settings on the IPv4 Settings tab, which include the temporary factory-shipped IP address.
  3. Assign the controller a unique network IPv4 address.
    No other device on this network should use this same IP address. Include the appropriate subnet mask used by the network.

    If you are enabling more than one LAN port (applicable to LAN1, LAN2, and WiFi), the IP address for each must be configured on different subnets, otherwise the ports will not function correctly. For example, with a typical Class C subnet mask of 255.255.255.0: setting Interface 1=192.168.1.99 and Interface 2=192.168.1.188 are invalid as both addresses are on the same subnet.

    Alternatively, if the network supports DHCP, you can enable it (click DHCP Enabled). In this case, the IP Address and Subnet Mask properties become read-only.

    In general, for stability, static IP addressing is recommended over DHCP. If DHCP is preferred, an IP Address Reservation should be entered for the controller in the DHCP Server. The controller IP address should not change.

    CAUTION: Do not enable DHCP unless you are certain that the network has DHCP servers! Otherwise, the controller may become unreachable over the network.

    If the JACE-8000 platform is to be used to wirelessly connect to the enterprise network, do not enable DHCP here. The WiFi adapter in Client Mode requires use of the controller’s DHCP feature. For more information, refer to the JACE-8000 WiFi Guide

  4. Review, and, if needed, adjust other TCP/IP settings, which, in usual order of importance, include:

    • IPv4 Gateway defines the IP address for the device that forwards packets to other networks or subnets.

      The JACE only supports one gateway for all adapters. This includes the JACE-8000 WiFi Adapter in Client mode.

    • DNS Domain Name provides the name of the network domain, or, if not applicable, leave it blank.

    • DNSv4 Servers enters the IPv4 address of one or more DNS servers. Click the add button () to open the property.

    • Hostname defaults maybe to “localhost,” or you may enter another name to use for this host. If you enter a Hostname, typically the name is unique for the domain.

      In some installations, changing Hostname may result in unintended impacts on the network, depending on how the DHCP or DNS servers are configured. If in doubt, leave Hostname at its default setting.

    • Hosts File opens a TCP/IP hosts file (click the edit property). The format for this file is a standard TCP/IP hosts file, where each line associates a particular IP address with a known host name. Each entry should be on an individual line. Place the IP address in the first column, followed by the corresponding host name. The IP address and the host name should be separated by at least one space.

    The Undo Changes button resets all settings (all Interfaces) back to the original pre-step values.

  5. To add a line, click at the end of the last line and press Enter, then type in the required data on the new line.
  6. To return to see all TCP/IP settings when you are done, click the control.
    This collapses the edit property.
  7. To continue, click the Next button.
    JACE-8000 and JACE-9000 controllers have two Ethernet ports, where Interface 2 is available for configuring the secondary (LAN2) Ethernet port. By default, this port is disabled, that is, it is without a default address. Its intended usage is for the secondary LAN port as follows:

    • Isolating a driver’s Ethernet traffic from the primary (LAN1) interface, or

    • Creating a private network by daisy chaining multiple IP devices off of the controllers secondary LAN port.

      This scenario requires that you configure the LAN2 port as a DHCP server and set up the Access Point WiFi mode.

    • In some cases, LAN2 may be set up with a standard, fixed, IP address that is used only by a company’s service technician, when on site. This allows access to the JACE without disconnecting it from the customer’s network, or without connecting the technician’s service PC to the customer’s network (which might go against local IT security policies).

      In any case, only one LAN port can be a DHCP server. If you are enabling LAN2, you must specify another (network) static IP address and the appropriate subnet mask, that is, a different subnet mask for each enabled LAN port IP address.

    • The JACE does not provide IP routing or a bridging operation among different Interfaces (LAN ports or WiFi).

  8. Once the controller is commissioned, you access the TCP/IP properties by expanding Platform and double-clicking TCP/IP Configuration
    The TCP/IP Configuration view opens.
