Ethernet Modual
Ethernet module is an extended communication module of Acuvim II
meter. With Ethernet module, Acuvim II meter can be linked to Ethernet
easily.
1.1 Ethernet Introduction
Ethernet was originally developed by Xerox and then developed further
by Xerox, DEC, and Intel. Ethernet uses a Carrier Sense Multiple Access
with Collision Detection (CSMA/CD) protocol, and provides transmission
speeds up to 10 Mbps.
Now Ethernet stands for LAN with CSMA/CD protocol.
Ethernet is not a material network, and it is the technology standard.
Ethernet is the most current communication standard in LAN. This
standard denes the used type of cable and the used method of Signal
processing in LAN.
1.2 Function Description of Ethernet module
Please read appendix of technical data and specifications of Ethernet
module before using it.
﹡The Ethernet module supports Modbus/TCP protocol. It is used as
server, and the default value of protocol port is 502, and the user dened
range of protocol port is 2000~5999. Device address is the same as
Acuvim II meter.
﹡The Ethernet module supports SMTP protocol. It has Mail Function and
supports “Send mail for timing” mode and “Send mail for event” mode.
﹡The Ethernet module supports HTTP protocol. It is used as HTTP server,

and the default value of protocol port is 80, and the scope of protocol
port is 6000~9999.

2.2 Installation Method
Ethernet module is linked to Acuvim II meter by communication plug. It
can also be linked to other extended modules like IO modules.
1. Insert the installation clips to the counterpart of Acuvim II meter,
and then press the Ethernet module lightly, so linking is established.
2. Tighten the installation screw.

Note:
1. lightly in installation or it may cause damage to the IO modules;
2. Installation with power is forbidden.
2.3 Denition of RJ45 Interface
The Ethernet module uses standard RJ45 connector access Ethernet
network. The mechanical and electrical characteristics of connector are
consistent with the requirements of IEC 603-7.

2.4 Cable
Shielded twisted-pair cable (standard 568A or standard 568B) is usually
recommended as reference to the EIA/TIA standard.
2.5 Connection Method
1. Direct Connect
Ethernet module use cross line (standard 568A) to connect to computes.
Users may refer to the third chapter “Function description of Ethernet
module” for using Ethernet module. Module supports Modbus/TCP and
HTTP functions for direct connect.
2. Indirect Connect
Ethernet module use straight line (standard 568B) access Ethernet
through router or hub. Users may refer to the third chapter “Function
description of Ethernet module” for using Ethernet module.

Detail of Ethernet module will be described in this chapter. It includes
how to set parameters of module, how to get IP address and Mac
address of module, content about Modbus/TCP protocol, how to visit
webs, and how to use mail function.
3.1 Initializing Ethernet Module
AXM-Net default settings are
IP Address (192.168.1.254);
Subnet Mask (255.255.255.0);
Gateway (192.168.1.1);
Primary DNS Server (202.106.0.20).
If you don’t know the settings of module when power on for the st time,
you may use the panel of Acuvim II to get them and to congure them.
This procedure shows how to configure Ethernet module settings by
panel:
a) Press “H” key and “V/A” key simultaneously on Acuvim II will go to the
menu selecting mode. Cursor “Meter” ashes in this mode.

b) Press “P” key or “E” key, move cursor to “Setting”. Press “V/A” key,
go to the meter parameter setting mode. Device address page is the rst
page of “Setting” mode. It shows the Modbus address of the device for
several seconds, and then the screen goes to Access Code page. Press “V/
A” key, go to the parameter setting page. Press “P” key or “E” key, move
cursor to “NET”, press “V/A” key, go to Ethernet module setting page.

c) Set conguration mode in the rst setting page. “AUTO” means that
users congure module settings with DHCP protocol while “MANU” means
that users configure module settings with manual setting. Press “V/A”
key, go to setting state, and the pointed area will ash. Press “P” key or
