Location of the Power Injector Module (EPI01)
The Power Injector Module (EPI01) should ideally be located in the computer room or network
cabinet close to the router. Identify which drop cable runs to the Hydro-Control’s location, and
using a short patch cable insert the Power Injector into that cable, connecting the port labelled
IN to the router output and the port labelled OUT to the drop cable. Connect a 240V or 110V
mains supply to the Power Injector.
Note: The Power Injector Module can supply sufficient power for a Hydro-Control V and a
sensor attached to it.

Connecting with Hydro-Control V
To communicate with a Hydro-Control V unit, start a terminal emulation
program such as HyperTerminal and set the connection properties as
shown, substituting the correct IP Address. Note specifically that the Port
number should be set to 10001.
The same “ * “ commands can be used as would normally be used over a
serial link, and the responses will provide the same information. Refer to
Chapter 4 of the Hydro-Control V Users Guide for more details of the
commands available.
Programming
An installation using the Ethernet Adapter packs the messages sent from a Host to the Sensor into an
Ethernet data packet, which is then unpacked by the Ethernet Adapter and converted into RS485 voltage
levels. If a custom application is being written to communicate with Hydronix sensors over the Ethernet,
then the Hydro-Link communications protocol should be implemented and the resulting message string
sent over the network to the Ethernet Adapter (instead of a serial port). In Visual Basic (VB6) this is done
using a WinSock control and in Visual Studio .NET this can either be done using a Sockets control or a
TCPClient control. A connection should be made from the Winsock or TCPClient control to port 10001 on
the Adapter. Further information on these controls can be found in the programming system
documentation, but please note that Hydronix are unable to provide technical support for developing
custom software applications
