Introduction
This chapter provides basic information about device. Before starting, please read
this manual carefully.
AR004798 two-channel current loop converter is designed to connect sensors with output
0-20mA or 4-20mA into Ethernet network. Current can be recalculated to physical
value measured by the connected sensor. Sensors can be powered directly from the
AR004798 Converter. AR004798 have two current inputs. These inputs are not galvanically
isolated.
General safety rules
The following summary is used to reduce the risk of injury or damage the device.
To prevent injury, please follow instructions in this manual carefully.
The device can be installed and repaired by a qualified person only. The device
contains no serviceable parts inside standard means.
Do not use the device, if it does not work correctly. Let check device by the
qualified service person if you think that is not working properly.
It is forbidden to use the device without the cover. Inside the device can be a dangerous
voltage and may be risk of electric shock.
Appropriate power supply adapter according to manufacturer specifications and approved
according to relevant standards may to be used only. Please make sure, that the adapter does
not have damaged cables or covers.
Connect the device to network parts approved according to relevant standards only.
Connect and disconnect the device properly. Do not connect or disconnect Ethernet cable
or current inputs when the device is powered.
Do not short-circuit power supply terminals +U1 and +U2 to the GND terminals.
The device may be installed in prescribed areas only. Never expose the device to higher or
lower temperatures than is allowed. Protect device from dripping or splashing water and do
not use in areas with condensation.
Do not use device in potentially explosive environments.
Do not stress the device mechanically.

Device description and important notices
This chapter contains information about basic features and device functional
safety.
Values from the device can be read using an Ethernet connection. The following formats are
supported:
•Web pages with XML and JSON files
•Modbus TCP protocol
•SNMPv1 protocol
•SOAP protocol
The device can also be used to check measured values and if the limit is exceeded, device
sends warning messages. Possible ways to sending warning messages:
•Sending e-mails up to 3 e-mail addresses
•Sending SNMP traps up to 3 configurable IP addresses
•Displaying the alarm status on web page
•Sending messages to Syslog server
The device setup can be made by the web interface. Latest firmware version can be obtained
from the technical support. Do not upload to your device firmware which is not designed
for it. Unsupported firmware can damage your device.
Reliability of warning messages delivering (e-mail, trap, syslog), depends on
actual availability of necessary network services. The device should not be used
for critical applications, where malfunction could cause to injury or loss of
human life. For highly reliable systems, redundancy is essential. For additional
information please see standard IEC 61508.
Never connect the device directly to the Internet. If it is necessary connect the
device to the Internet, properly configured firewall must be used. For a remote
connection to the device should be VPN or similar secured access used only.

Getting started
Here you can find information necessary to put newly purchased equipment to
operation. Read information about current loop connection carefully.
What is needed for operation
To install the unit, you need to the following equipment. Please check if it is available before
installation.
•AR004798 current loop converter
•screwdriver for removing cover
•power supply –according to specification (commonly DC 24 V/1.0 A)
•RJ45 LAN connection with appropriate cable
•free IP address in your network
•sensor(s) with current loop output (4-20mA or 0-20mA)
Mounting the device
•check if the equipment from the previous chapter is available
•install the latest version of TSensor software. This software will help you find
device on network and to change IP address of the device. Device configuration
is made using web interface. TSensor software can be downloaded from the
manufacturer’s website.
•contact your network administrator to obtain following information for the
connection to the network:
IP address:
_____._____._____._____
Gateway:
_____._____._____._____
Netmask:
_____._____._____._____
DNS IP address:
_____._____._____._____

•check if there is no IP address conflict when you connect the device into
network for the first time. The device has from factory set the IP address to
192.168.1.213. This address must be changed according to information from the
previous point. When you install several new devices, connect them to the
network one after another.
•remove device cover, connect current loops, and power supply terminals
according to image below. Inputs channels on the device are not
galvanically isolated. Power supply is not isolated from inputs as well!
Device is isolated from communication line side only. Carefully consider how
connect sensor with current output into your AR004798.
•close device cover
•connect the Ethernet connector
•power on the power supply adapter
•LEDs on LAN connector should blink after connecting the power

•run configuration software TSensor on your PC
•switch to an Ethernet communication interface
•press button Find device...

•the window shows all available devices on your network
•click to Change IP to set new address according to network administrator
instructions. If your device is not listed, then click Help! My device wasn’t
found! Then follow the instructions. MAC address is on product label. The
device is factory set to IP 192.168.1.213.
•gateway may not be entered if you want to use the device in local network only.
If you set the same IP address which is already used, the device will not work
correctly due to IP address collision. If the device detects a collision of IP
address, then reboot is performed automatically.
•after changing IP address device is restarted and new IP address is assigned.
Restart of the device takes up to 10 seconds.
•connect to device using TSensor software. TSensor software will forward you
to web interface. On the web interface you can set your device according to
requirements.

Device setup
This chapter describes basic device configuration. There is a description of settings
using web interface.
Setup using web interface
Web interface can be managed by the web browser. Main page will be shown when you insert
device address into address bar of your web browser. There you find actual measured values.
Page with history graphs is shown when you click to tile with actual values. Access to device
setup is possible via tile Settings.

General
Device name can be changed using item Device name. Measured values are stored into
memory according to History storage interval field. After changing of this interval all
history values will be cleared. Be aware that content of memory for history values is not
preserved after device restart or power lost. Changes must be confirmed by Apply settings
button.
Network
Network parameters can be obtained automatically from DHCP server using option Obtain
an IP address automatically. Static IP address is configurable via field IP address. It is
not necessary setup Default gateway while is device used inside one subnet only. DNS
server IP is used to resolving addresses for SOAP protocol or communication with SMTP
(mail) server. Option Standard subnet mask sets network mask automatically according to
A, B or C network class. Subnet mask field must be set manually when network with non-
standard range is used. Periodic restart interval enables to restart device after selected time
since device start.
