1 Quick Start
If you’re familiar with setting a computer’s IP address and have a cross-over cable and a
power injector, the quickest way to establish communications with a Thermo Scientific
AquaSensors Ethernet product is to:
Figure 1: A diagram of an isolated Ethernet DataStick network.
Figure 2: A diagram of an isolated AV38 network.
1. Change the computer’s IP address to 192.168.0.1.
2. Plug the product into the PoE-side of the power injector.
3. Connect the power injector to the computer using a CAT5 cross-over cable.
4. Point your Web browser at 192.168.0.100 to see the Home Page.
The Home Page will show the product’s measurement values, configuration and
diagnostic information. From there, the product’s IP address can be changed if desired
by clicking on the CommSettings button.
If you’re not familiar with setting a computer’s IP address, see Section 3 for a detailed
description of the configuration procedure.

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.
