Chapter 3 Connecting with Hydro-Control V
Introduction
The serial port of a Hydro-Control V unit may be connected to the RS232 port of an Ethernet Adapter to
allow remote access to recipe configuration and mix logs.
This cannot be done while an Adapter is communicating with sensors, as a different communications
protocol is used. Installation will be similar to one of the options described above, except that the RS232
Tx, Rx and GND signals will be connected to the Hydro-Control V unit.
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
The most basic setup uses only the Ethernet adapter and is arranged as shown below:

Location of the Ethernet Adapter (EA01)
The Ethernet Adapter should be mounted in the wiring junction box as close to the Hydro-Control
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,
