GENERAL OVERVIEW
2.1 VMU-C EM
VMU-C is conventional energy monitoring Web server based on Web technology. Once
properly set up, the VMU-C EM software can be used through the net
– both LAN and
Internet
– through any PC or device equipped with a common Internet browser.
As VMU-C EM is based on the Web technology, it can be used as an ordinary Web site;
the data and status display function for the devices installed in the plant (analysers,
meters, environmental sensors) is based on the innovative AJAX technology, allowing to
send and receive information without having to reload the graphical pages.
2.2 ACCESS TO THE SYSTEM
To access the system, you first need to establish a network connection between your PC
and VMU-C EM, using the LAN port existing on the device; you have the following
options:

Directly connect the two devices (VMU-C EM and PC) through a network cable

Connect both devices (VMU-C EM and PC) to your local network

Directly connect the two devices (VMU-C EM and PC) through a USB/mini-USB
cable.
The VMU-C EM default address is 192.168.1.110 ; in any connection configuration; this
implies that, in order to be able to communicate with VMU-C, your PC must belong to the
same sub-network; that means its IP address must be
“192.168.1.x” , where “x” must be a
number ranging between 1 and 254, other than 100.
Technical support operators can also communicate with the VMU-C EM through the
same LAN port, using the address 192.168.253.254 (this address is fixed and cannot be
changed).
If using a mini-USB cable to connect the devices, use the address 192.168.254.254.
If your network setting is different (the first 3 number are not the prescribed ones) you
need to temporarily modify your network setting as specified above; then, as described
below, after accessing the software you can modify the VMU-C EM network parameters,
to ensure that it is compatible with your network, and finally restore your original network
setting.
After configuring your IP address, open an Internet browser and type the following
address:
http://192.168.1.110
