Cable Wiring

If you buy your cabled sensor with a connector installed
(the normal configuration), no further wiring is needed.
For reference purposes, the first three diagrams below
show the pinout from the connector for various scenarios.
The final diagram shows the pinout if you bought your
sensor without a connector for use with SDI-12.

Installing Aqua4Plus 2.0
The PT2X comes with the Aqua4Plus 2.0 host software
that is installed on your PC or laptop. Use this software to
program the datalogger, to retrieve data from the logger,
to view collected data, and to export data to external files
for use with spreadsheets or databases.
Refer to the software manuals for details on installing and
using Aqua4Plus 2.0.

Using the PT2X Without Aqua4Plus 2.0

Most users will use the PT2X with Seametrics' Aqua4Plus
2.0 software. However, the PT2X is quite versatile,
communicating via either Modbus
allowing you to do the following:
• Read a PT2X via Modbus
• Read a PT2X via SDI-12 protocol.
• Display readings from a PT2X on a panel meter.
If you want to use one of these methods, see page 20.
