1. Introduction to Ethernet
The AXM-WEB2 module provides a dual Ethernet and WiFi communication channel for Acu-
vim II series power meters. Users will be able to use both Ethernet ports and WiFi simulta-
neously with di󳆁erent networks and data acquisition systems.
This communications module provides users with an industry leading 100ms and 40ms re-
sponse rate via Modbus TCP that allows users to attain real time updates to key parameters
such as voltage, current and power from the Acuvim II Series meter.
Introduction to Ethernet
Ethernet was originally developed by Xerox and then further developed by DEC and Intel.
This networking technology uses Carrier Sense Multiple Access with Collision Detection
(CDSM/CD) protocol and provides transmission speeds up to 100Mbps.
Ethernet is a not a network but more of a standard. It is the most current communication
standard Local Area Network(LAN). This standard de󳆂nes the type of cable that is used and
the method of Signal Processing. The AXM-WEB2 module supports two Ethernet channels.
IPv6
The AXM-WEB2 module also supports IPv6 which is the latest version for the internet pro-
tocol. The protocol uses 128-bit addressing in comparison to IPv4 which uses 32-bit ad-
dressing. The di󳆁erence for addressing allows for more devices to be connected using IPv6
as opposed to the IPv4 protocol. The protocol is more e󳆄cient and provides more secure
routing over the internet.
2. Functional Description of the Ethernet module
The AXM-WEB2 module supports a wide range of communication protocols. Some of the
more commonly used protocols are brie󳆃y explained below.
This module supports the Modbus-TCP protocol. When connected to the Acuvim II series
meter, it is a slave device that can only respond to queries. The default value for the Modbus
Port is 502. The user de󳆂ned range is 2000~5999.
The AXM-WEB2 grants users the ability to send emails based on a time interval or when
there is a triggered event using the SMPT protocol. It can send mail from encrypted servers
and servers that use di󳆁erent SMTP ports.
The AXM-WEB2 protocol supports HTTPS protocol. It is used as an HTTPS server and where
the default value of the protocol port is 443. Using the HTTPS protocol, the AXM-WEB2 can
send post requests to both HTTP and HTTPS servers.

4. Installation Method
The AXM-WEB2 module is linked to the Acuvim II series meter by a communication plug. Other
extended modules such as the IO modules can be linked to the Acuvim II series meter through
the AXM-WEB2.
1) Remove cover from the back of the Acuvim II series meter which will expose the socket.
2) Insert the installation clips to the grooves in the Acuvim II series meter and then press the
AXM-WEB2 module lightly to establish a linking between meter and module.
3) Tighten the installation screws.
NOTE: Installation with power to the meter is forbidden. The module must be installed/unin-
stalled while the meter is powered o󳆁.

5. De󳆂nition of RJ45
The AXM-WEB2 uses two standard RJ45 connectors to access the Ethernet network. The
mechanical and electrical characteristics of the connector are consistent with the require-
ments of IEC 603-7.

6. Initializing the Ethernet module
The default settings in the Acuvim II series meter are as followed:
Ethernet 1 (Static IP address)
IP Address (192.168.1.254)
Subnet Mask (255.255.255.0)
Gateway (192.168.1.1)
DNS Server 1 (8.8.8.8)
DNS Server 2 (8.8.4.4)
Modbus Port 502
Ethernet 2 (Dynamic IP address)
By default Ethernet 2 is con󳆂gured for DHCP, meaning the network will dynamically
assign its network properties. In order to view the Ethernet 2 IP address from the me-
ters display the Acuvim II meter must be con󳆂gured to the WEB2 protocol. The following
explains how to change the meters protocol settings to work with the WEB2 module:
• Press the 'H' and 'V/A' buttons simultaneously on the Acuvim II series. Release the buttons
and the meter will enter the meter selecting mode, as indicated by the 󳆃ashing 'Meter'
cursor.

• Press the 'P' or 'E' button to move the cursor to 'Setting'. Press 'V/A' button to enter the pa-
rameter setting mode. The device address page is the 󳆂rst page of the 'Setting' mode. It will
show the Modbus address of the meter for a second before prompting for the password of
the device.
• You will be required to type in a password in the ‘PASSWORD’ screen. Leave the password
as default ‘0000’ and press ‘V/A’ to enter the parameter selection Mode.

• Press ‘V/A’ to modify the setting; the cursor should now 󳆃ash.
• Press ‘P’ or ‘E’ to select 'WEB2'.
• Press ‘V/A’ to con󳆂rm the change.
Once the protocol 2 setting of the Acuvim II meter is con󳆂gured for WEB2, users can now view
all necessary settings in the meters NET settings.
Press the 'H' button to exit the system setting, you will be directed to the parameter selection
screen.
Press the 'P' or 'E' button to move the cursor to 'NET' and press the 'V/A' button to enter the
Ethernet module settings.

• The 󳆂rst page of the NET Settings will be the N01 DHCP setting. By default this is con󳆂g-
ured to Manual. Setting this con󳆂guration to Auto will allow the router to assign the meter
with an IP address, whiles Manual will allow the user to con󳆂gure the IP address. Press the
'V/A' button to enter edit mode. Press 'P' or 'E' to change the setting and press 'V/A' to con-
󳆂rm .
NOTE: If the DHCP is selected as Auto, the Ethernet module needs to be rebooted before it can
be assigned with the new IP address.
• Press 'P' to get to "N02 IP address" This is the IP address for Ethernet 1 and can be used to
access the web interface of the module. Users can con󳆂gured the IP address if the DHCP
is con󳆂gured to Manual. Press 'V/A' to con󳆂gure the IP address. The cursor of the 󳆂rst digit
will begin to 󳆃ash. Press the 'H' button to scroll through the digits, press the 'P' or 'E' to
change the value of the 󳆃ashing cursor and press 'V/A' to con󳆂rm.

Chapter 8: Connection Method
7. Cable
An RJ45 cable is needed to connect the meter to the network.
A shielded twisted pair cable(standard 568A or standard 568B) is recommended as refer-
ence to the EIA/TIA standard.
8. Connection Method
8.1 Direct Connect to a Computer
The AXM-WEB2 can be connected to a computer using a crossover cable(standard 568A). The
AXM-WEB2 module supports Modbus-TCP and HTTPS Functions for this method of connection.
To connect meter directly to the computer, the computers IP must be within the same subnet
as the meters IP address. The following steps outline how to change the computers IP using a
computer running the Windows OS::
• Manually connect the meter via Ethernet cable to the computer
• Right click on the connection icon
• Select "Open Network Sharing Center"
