Thermo Scientific AquaSensors™DataStick™Ethernet Communications User Guide 7
2 Introduction
This document describes the configuration and operation of the Thermo Scientific
AquaSensors Ethernet Communications product. It applies to V1.02.00 firmware or later.
The product is offered in two forms. The first form is as a Communications Adapter as
shown in Figure 3 that is plugged into the DataStick Body.
Figure 3: The Ethernet Communications Adapter.
The second form is as an option in the AV38 Local Display as shown in Figure 4.
Figure 4: The Ethernet option in the AV38 Local Display (front and rear views).
The product provides full-featured measurement, configuration, calibration and
diagnostics of any DataStick™ measurement system from any Ethernet-enabled device
via resident Web pages, EtherNet/IP, Modbus TCP, or Programmable Controller
Communication Commands (PCCC). An intermediate analyzer is not required.

Thermo Scientific AquaSensors™DataStick™Ethernet Communications User Guide 8
In either form, the product supports the following protocols:
•EtherNet/IP
•Modbus TCP
•Programmable Controller Communication Commands (PCCC)
•TCP/IP (IPv4)
•UDP
•ICMP (for ping response)
•TFTP (for upgrading firmware)
The Ethernet Communications Adapter (Adapter) has a diameter of about 1 inch, a length
of about 4.5 inches, and it protrudes from the end of the DataStick Body by about 3.1
inches as shown in Figure 5.
Figure 5: Dimensions of the Adapter.
It has an integral CAT5 industrial Ethernet cable with an RJ45 connector on one end that
can be plugged in to any PoE switch or power injector. On the other end of the Adapter
is a keyed O-ring-sealed connector that can be plugged into any Thermo Scientific
AquaSensors DataStick. There are red and green LED indicators on this end of the
Adapter that make it easy to know when the Ethernet link is active. The cable can be up
to 100 meters (328 feet) long although we recommend that the Adapter be ordered with
10–30 feet of cable to reduce cost.
When plugged into a DataStick sensor system the Adapter becomes an integral part of the
measurement system and the system can be mounted as any industrial sensor would be
mounted for continuous use in process applications. Figure 6 shows an Adapter detached
from a DataStick with a toroidal Sensor Head.
Figure 6: Ethernet Communications Adapter shown detached from a DataStick with a toroidal
Sensor Head.
The Adapter can be used for direct access to DataStick measure, calibrate, configure and
diagnose information, even when the Sensor Head is changed from one type of analytical
measurement to another with power applied. The DataStick automatically supports
multiple measurement types and all Sensor Heads are automatically supported.

Thermo Scientific AquaSensors™DataStick™Ethernet Communications User Guide 9
Refer to the DataStick Manual for detailed information on installation, maintenance and
operation of sensors.
The Ethernet option in the AV38 Local Display provides an RJ45 jack for connection to a
power injector or 802.3af-compliant (PoE) Ethernet hub or switch as shown on the right
side of Figure 4. It allows network access to the Modbus RTU DataStick connected to
the AV38.
In this form, power for the Ethernet option is provided by a Power-Over-Ethernet device,
and power for the AV38 Local Display is provided by an external 24 VDC power supply.
This manual includes only the Ethernet option in the AV38. For information about the
rest of the AV38, please see the AV38 User’s Manual.
3 Hardware Setup
Both forms of the product possess the same default communications settings. They are as
follows:
IP Address: 192.168.0.100
Subnet Mask: 255.255.255.0
Gateway Address: 192.168.0.1
Both forms support a data rate of 10 Mbps (10Base-T).
Both forms comply with the IEEE 802.3af Power Over Ethernet standard and, as such,
are termed powered devices (PD). This means that they receive their power via the
Ethernet network.
Power Classification: Class 1
Supply Voltage: 44–57 VDC, 48 VDC nominal
Supply Current: 25 mA @ 48 VDC
They are insensitive to the polarity of the power supply and are capable of operating in
either Mode A or Mode B as shown in Figure 7 and Figure 8, respectively.

4 Configuration Procedures
The product is shipped from Thermo Fisher Scientific with a static IP address, subnet
mask and default gateway that can be changed by the user to conform to specific
networking requirements. These changes can be made from the resident Web page.
The product stores communications settings and other information in its own non-volatile
memory. You must, therefore, access the product to view and edit these parameters.
Changes to the IP Address, Subnet Mask, and Gateway Address require that you reset the
product before the new settings take effect. You can reset the product by cycling its
power.
Please contact Thermo Fisher Scientific for a list of networking infrastructure hardware
that includes manufacturers of power injectors as well as 802.3af-compliant industrial
and home/office Ethernet switches.
Note: When the Ethernet product’s cable is moved from one port on
an Ethernet switch to another, communication with that product will
not be possible until the tables inside the switch are rebuilt by cycling
the switch’s power.
Optionally, a virtual private network (VPN) can be established between Thermo Fisher
Scientific and the customer’s site to allow Thermo Fisher Scientific to configure and
diagnose Ethernet communications products and upgrade them if necessary.
The default static IP address for Thermo Scientific AquaSensors Ethernet products is
provided on a paper tag for initial access and setup. When connecting to a network, be
sure to configure an IP address that will not be in conflict with other devices or DHCP
servers on the network. If there is an IP address conflict, several devices on the network
may not communicate.
Note: It is important to tag Thermo Scientific AquaSensors Ethernet
communications products with currently configured IP address
information so that they can always be accessed.
Thermo Fisher Scientific ships Ethernet communications products with a paper tag that
gives currently configured IP address information along with a permanent tag that gives
the MAC address. For customers that order a preconfigured IP address, a permanent IP
address label can be provided.
In the event that the IP address for a Thermo Scientific AquaSensors Ethernet product is
lost, there are two ways to regain communications. The first involves a Discovery Utility
provided by Thermo Fisher Scientific that will find all Thermo Scientific AquaSensors
Ethernet communications products on a network and allow their IP addresses, subnet
masks and default gateways to be changed. The second involves restoring the settings to
default values as described in Section 3.
Configuration procedures in this section are explained using the Windows xp operating
system. When other operating systems are used, procedures may be slightly different.
When possible, obtain an IP address, subnet mask and default gateway from a network
administrator.
