NetCommander Power Monitor V1.1
1 NetCommander Power Monitor Introduction
NetCommander Power Monitor is a powerful tool to monitor, log and review Utility
usage. This manual will explain how to get the best out of the your product and be a
very useful aid to the Buildings Part L approvals process.
2 Getting started
2.1 Equipment checklist
Please make sure that the following components are in the box. If anything is
missing, please contact your dealer.
 NetCommander hardware
 240v/12v mains adapter
 Sensors as ordered, 1 or 3 Current Sensors and an optional Voltage Sensor
Cxxx-yyy1 1 Current sensor
Cxxx-yyy1 3 Current sensor
 Optional Wireless Ethernet module
Cxxx-yyy1 1 Current sensor + Wireless Ethernet Module
Cxxx-yyy1 3 Current sensor + Wireless Ethernet Module
Axxx-yyy optional voltage sensor
2.2 Network Types
2.2.1 Typical Business Network
The power monitor solution is designed to work in a typical business environment of
wired or wireless Ethernet solution. The NetCommander may well need a different IP
address allocated to it, this can be changed as detailed in Section 4 below. Note the
Visual Display front end will also need to be changed to match the new IP address
(see section 5 below)
2.2.2 Typical Home Broadband Network
Broadband home networks typically run from a wireless router. Most routers default to a
192.168.1.xxx network, and hence the default address of 192.168.1.150 will work with
no changes. It is important that at set-up time the DHCP range of the broadband router is
checked to ensure it does not include the 192.168.1.150 address in its range. If it does
include the .150 address, it must be changed so that this address is outside the range or
NetCommander needs its address changing, so that it is not included in the DHCP range.
See section 4.
It is assumed that the router has its address configured as 192.168.1.1, again if not,
section 4 explains how this can be set.

NetCommander Power Monitor V1.1
3 Installing Hardware
The NetCommander hardware comes fully tested and ready for use.
The default IP address of 192.168.1.150 is designed to work with most broadband
routers “out of the box”. It can be changed as detailed below (section 4).
If there is no need then the PSU can be connected, but do not turn on until the
sensors are all installed and connected.
3.1 Installing sensors
The sensors are to be added as in the picture below, if only one sensor is ordered
this plugs into the first port labeled “L1” for three phase monitoring all three ports
will be used, in this case the “L1” corresponds to the Red (Brown) phase, L2 to
Yellow (Black) and L3 to Blue (Grey), note: new phase colours in brackets. The
Sensor fully isolate the NetCommander from the mains voltage and no harm can be
done plugging in sensors with power applied. The clamp on the sensor should be
opened and the sensor closed round a single mains conductor as close as possible to
the electricity supply meter. The sensor will NOT work if it is clamped round a
conductor containing both live and neutral cables.

3.2 Installing Wireless Ethernet
The Wireless Ethernet module is factory defaulted to:IP address (from NetCommander) of 192.168.1.150
SSID of xxx
Encrytion xxx
If the Netcommander is to be connected DIRECTLY to a PC then a cross-over
Network cable needs to be used, usually the connection is made via a hub or switch
(as with the optional Linksys wireless router) in which case a straight through
(normal) network cable should be used.
To change SSID or Encrytion type then insert the supplied Linksys CD and follow the
instructions.
4 Changing IP address
The IP address is set as 192.168.1.150 with a Mask of 255.255.255.0 and a gateway
of 192.168.1.1. These numbers are chosen to be compatible with the standard setup to interface to a broadband router. If any of these need changing then follow this
procedure.
Note 192.168.1.0, 192.168.1.1, 192.168.1.254 and 192.168.1.255 addresses must
not be set on the NetCommander.
The following section details with changing the IP address of NetCommander. After
completing this section the user should have full access to NetCommander.
1. Connect the serial communication cable between NetCommander's serial port
and a spare serial port on the local PC, make a note of the PC serial port used
(COM1, COM2 etc.). If you are not using a PC, then note the device port.
>> Serial cable supplied ??? type of cable
2. Start the Terminal/Hyperterm utility and set the following communications
parameters.
