Ethernet operation
mode
Disabled
Ethernet constantly off (recommended when not in use)
Disabled
Automatic
configuration
the DHCP client is on, parameters IP address , Subnet mask, ,
Default gateway , and DNS server are set automatically
Manual
configuration
the DHCP client is off, parameters IP address , Subnet mask ,
and Default gateway are set manually
DHCP server
useful for direct connection with a computer; do not use in
networks with an existing DHCP server,
after this option is set, the device must be restarted
NetBIOS name
a unique name of the recorder in the local network; may be used instead of the
IP address in order to establish a connection with a computer. Edition of the
name (no spaces, max. length 15 characters) is possible on the computer (via
the USB port or the Ethernet and the ARSOFT-CFG software, or by copying the
configuration - chapter 12.3). The format of a section in the
AR407.txt file is the
following: [Ethernet] NetBIOSName= AR407 . The changed name may not be
available on the network immediately (the update time depends on the
configuration of the network).

( except for 137)
the port number and the individual IP address of the device
for communication using the MODBUS-TCP protocol and with
the ARSOFT-CFG and LOG software, and with the web
browser (in the address field, enter
http:// IP address or
NetBIOS name , e.g. http://192.168.0.207 or h ttp://AR407 )

Dynamic DNS server
client (DDNS)
Disabled
A DDNS service that enables access over the Internet to a
recorder connected to a network without a fixed public IP
address; an active account in a DDNS service is required; the
description can be found in chapter 12.8.1.
Disabled
Enabled
Dynamic DNS
settings and status
Configuration data and status of the DDNS service. The data can be edited on the computer
(via the USB port or the Ethernet and the ARSOFT-CFG software, or by copying the
configuration - chapter 12.3). Available parameters of the service: DDNS server index, host
name, username and password. The default section
[DDNS] in the AR407.txt file is the
following: ServiceIndex= 1 (0=DYNDNS_ORG, 1=NO_IP_COM, 2=DNSOMATIC_COM),
Host= AR407example.ddns.com , UserName= DDNSuser , Password= DDNSpassword
Website automatic
refresh time 0 ÷ 60 s , change every 1 s, in the case of the 0 value, automatic refreshing is
switched off (manual refreshing), it is used by the WWW server
5 sec.
MAC physical
address
a unique permanent hardware address of the Ethernet interface (factory-assigned, non-
modifiable)
Notes: (1) - a new scanning period is used in the system after the old expires in all sensors.
It is recommended to set the largest possible value of this time in order to save the batteries in wireless
sensors and to increase resistance to any disturbances in the radio communication
(2) - connection of the recorder to a USB port of a computer stops recording until the cable is
disconnected and blocks the performance of file operations available from the menu level and
transmission of files with measurement data via Ethernet from the ARSOFT-LOG level
NOTE:
Do not connect the device in the USB memory support (host) mode to the USB port of a computer as this leads to
the risk of damage to the ports. Do not use two USB sockets at the same time .
