Multiple Network Ports; Firewall; General Web - Ametek VTI Instruments EMX-75 Series User Manual

Multiple Network Ports

It is possible that the user computer, can have multiple network adaptors (physical/virtual).
Common example of this case, is use of Wireless Internet/Wi-Fi in Laptop computers, whose
Wired Ethernet connections are connected to LXI device connected network. In some cases,
virtual network adaptors could have been created for use by some of the installed applications on
user system. The easy solution to these problems is to disable all other Ethernet connections and
so force the computer to select the network port which is used by LXI Instrument.

Firewall

It is possible that the firewall of the computer may be stopping the data traffic to the connected
LXI device. It may not be always feasible to stop the Firewall completely, and hence the user may
contact their computer administrator for making exceptions in Firewall configuration to allow LXI
data traffic. Here are the list of ports and protocols, typically used by LXI devices.

When initial connection is made to the EMX-2500, the instrument home page, or Index, appears.
This page displays instrument-specific information. This page is accessible from any other
instrument page by clicking on the EMX-2500 web page header. The EMX-2500 Navigation
Menu is displayed on the left hand side of every internal web page. The entries on the Navigation
Menu represent two types of pages:
