Installation
Device Management Utility
The Device Management Utility that is included with NETRS2321E (ETM.exe) is used to
detect and setup the installed adapter. When this tool is installed and activated, it will
detect the existence of the installed adapter, and depict its status including IP Address,
Subnet Mask, MAC Address and Device ID as shown below. The Setup Tool can only
congure one adapter at a time, therefore if there are multiple adapters installed on the
network, please ensure that they are not connected (or shut down) prior to installation.
Due to the nature of broadcast UDP packets, ETM has the following characteristics:
• Broadcast packets are not limited by subnet. Even if the IP Address of the converters
and the computer running ETM do not belong to the same subnet, it will still
function correctly.
• Broadcast packet signals cannot be passed through a router. ETM can only be used
to monitor devices with ETM installed, in the same segment of the LAN.
To begin using the Device Management Utility, copy the le titled ETM.exe from the
Driver CD that accompanied your NETRS2321E purchase, to your desktop. The le can
be located in the following path on the Driver CD:
E:\ETM (E: represents the CD/DVD-ROM drive)
Once the le has been copied to the desktop, connect NETRS2321E to your LAN, using
the available LAN port. Connect the included power adapter (9V DC, 500mA) to the
power port provided on NETRS2321E. Wait for a few moments for the device to be
detected, and double click on the ETM.exe icon to launch the application:
