Configuring TCP/IP settings
At the TCP/IP Configuration step, perform the following steps:
1. Review the Interface 1 settings on the IPv4 Settings tab, which include the temporary factory-shipped IP address.
2. Assign the MultiSITE VM3 a unique IPv4 address for the network you are installing it on. No other device on this network should use this
same IP address. Include the appropriate subnet mask used by the network.
Note:
• If enabling more than one LAN port (applicable to LAN1, LAN2, and WiFi) then the IP address for each must be configured on different sub-
nets, 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 is an invalid configuration, as both addresses are on the same subnet.
Do not enable DHCP unless you are certain that the network has DHCP servers. Otherwise, the controller may become unreachable over
the network.
Alternatively, if the network supports DHCP, you can enable it (click DHCP Enabled). In this case, the IP Address and Subnet Mask fields
become read only.
Note that 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 must not change.
If the MultiSITE VM3 platform is to be used to wirelessly connect to the enterprise network, DHCP must not be enabled here. In that event,
the WiFi adapter in Client Mode will require use of the MultiSITE VM3 DHCP feature.
3. Review, and if needed, adjust other TCP/IP settings, which (in usual order of importance) include the following:
• IPv4 Gateway: The IP address for the device that forwards packets to other networks or subnets.
Note that the MultiSITE VM3 only supports one gateway for all adapters. This includes the MultiSITE VM3 WiFi Adapter in Client mode.
• DNS Domain Name: Enter the name of network domain, or if not applicable, leave blank.
• DNSv4 Servers: Click the Add icon for a field to enter the IPv4 address of one or more DNS servers.
• Hostname: Default may be "localhost," or enter another name you want to use for this host. If a hostname is entered, typically the name
is unique for the domain.
Note that 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 default.
• Hosts File: Click control to expand edit field. Format 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. The IP address should be placed in the first column, followed by the cor-
responding host name. The IP address and the host name must be separated by at least one space.
a. To add a line, click at the end of the last line and press Enter.
b. Type in the required data on the new line.
To return to see all TCP/IP settings, click the control to collapse the edit field when done.
The Undo Changes button resets all settings (all Interfaces) back to the original pre-step values.
4. Click the Next button to go to the next step.
MultiSITE VM3 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 without a "default" address. Intended usage is for the following purposes:
• Isolating a "driver's" Ethernet traffic from the primary (LAN1) interface, or,
• 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 MultiSITE VM3 without disconnecting it from the customer's network, or without connecting the techni-
cian's service PC to the customer's network (which might go against local IT security policies).
In any case, note that only one LAN port can be set as DHCP. If enabling LAN2, you must specify another (network) static IP address and the
appropriate subnet mask. The MultiSITE VM3 does not provide IP routing or bridging operation between different Interfaces (LAN ports or WiFi).
