Chapter 3 Connecting with Hydro-Control VI
1 Introduction
The serial port of a Hydro-Control VI 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 in the
previous chapter, except that the RS232 Tx, Rx and GND signals will be connected to the Hydro-
Control VI unit.
2 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.
In order to maintain compliance with the relevant product directives, this equipment should only
be installed and used with the approved components supplied by Hydronix. Unauthorized
modifications to these units could void the units compliance and invalidate the users right to use
the equipment.
