Chapter 1 Introduction
The Hydronix Ethernet Adapter provides a simple method of network enabling Hydronix products. The
Adapter is a small DIN-rail mounted unit that converts packets received over an Ethernet (TCP/IP)
network to RS485 or RS232. This enables a host PC elsewhere on the network to communicate with
sensors using Hydronix Hydro-Com software. Remote configuration and control of a Hydro-Control V
unit is also possible.
An option of using Power over Ethernet is available via a second small DIN-rail module to eliminate the
need for a local 24V supply for the sensors.

Chapter 2 Connecting with Sensors
Installation
Depending on the installation option chosen, the system should be set up as shown in the diagrams
below. Terminal identification for each module is shown later in this chapter.
Ethernet Adapter Only (EA01)
The most basic setup uses only the Ethernet Adapter and is arranged as shown below:

Figure 2: Connections for Ethernet Adapter only
Location of the Ethernet Adapter (EA01)
The Ethernet Adapter should be mounted in the wiring junction box as close to the sensors as
possible, and protected from water and excessive dust. Connect the Ethernet drop cable from
the network connection to the Ethernet port of the Adapter. Connect a 24V dc supply to the
24V+ and 0V input terminals of the Ethernet Adapter, ensuring that the power supply and wire
is of a sufficient power rating to carry the power for the number of sensors connected.
Connect the RS485 sensor cable to the Ethernet Adapter outputs, taking care to note the
recommendations in the RS485 Wiring Recommendations in Chapter 3.

Power over Ethernet (EPK01)
To eliminate the need for a local 24V supply for the adapter and sensors, the optional Power over
Ethernet kit can be used. The arrangement is as shown below:

Figure 3: Connections for Ethernet Adapter and Power Adapter
Location of the Power Adapter (EPA01)
The Power Adapter Module (EPA01) should be mounted in the wiring junction box close to the
sensors and beside the Ethernet Adapter, protected from water and excessive dust. Connect
the Ethernet drop cable from the router to the IN port of the Power Adapter. This cable carries
both the power and the Ethernet communications signals. Connect a short Ethernet cable from
the OUT port of the Power Adapter to the Ethernet port on the Adapter. This cable carries only
the Ethernet communications. Connect short insulated wires from the 24V+ and 0V outputs of
the Power Adapter to the 24V+ and 0V inputs of the Ethernet Adapter, ensuring that the wire is
of sufficient power rating to carry the power for the number of sensors connected.
Connect the RS485 sensor cable to the Ethernet Adapter outputs, taking care to note the
recommendations in the RS485 Wiring Recommendations in Chapter 3.
Sufficient ventilation and cooling should be employed to keep the air temperature around the
unit to a suitable level for the number of sensors being powered. The diagram below shows
the number of sensors that can be used at different air temperatures for each sensor type.
