4 Introduction
When the "OTT SDI-12 Interface" PC software is used, the "USB/SDI-12 Adapter"
provides the option of changing an existing SDI-12 sensor configuration via the
SDI-12 or RS-485 interface (SDI-12 protocol).
For this purpose, the sensor must be temporarily connected to the PC via the inter-
face converter.
The PC Software automatically recognizes the connected sensor type and provides
the appropriate SDI-12 commands conveniently as buttons. The software differen-
tiates between "Standard SDI-12 commands" and "Extended SDI-12 commands".
It is also possible to update the firmware of the sensors. For the OTT PLS-C pres-
sure sensor with conductivity sensor, an additional button is available for calibrat-
ing the conductivity sensor.
The "USB/SDI-12 Adapter" supports for example the following sensors:
– OTT Pluvio2 Precipitation Gauge,
– OTT PLS/OTT PLS 500 Pressure Probe,
– OTT PLS-C Pressure Probe with Conductivity Sensor,
– OTT RLS Radar Level Sensor,
– OTT CBS Bubble Sensor,
– OTT SE 200 Shaft Encoder,
– Side Looking Doppler OTT SLD.
You can also connect sensors from third-party manufacturers with a standard
SDI-12 interface. The software also provides buttons for standard SDI-12 com-
mands for these. In this case you can enter extended SDI-12 commands using an
SDI-12 Terminal Mode.

Adapter
5.1 Using the RS-485 interface
Please note:
▶The OTT USB/SDI-12 Adapter can supply a connected sensor with a maximum
current consumption of 100 mA. Beyond this, a separate power supply for the
sensor is required. If the green/red LED at the USB/SDI-12 Adapter lights up
red continuously during operation, the current consumption of the sensor is too
high!
▶For individual sensor types, it may be necessary to swap the connected wires at
RS-485 A and RS-485 B for trouble-free operation!
▶Maximum cable length/specification: see operating instructions of the connect-
ed sensor.

face using the OTT FAD 5 connecting kit
The connection variant described here shows the connection of the OTT PLS-C
to the OTT USB/SDI-12 Adapter using the "OTT SDI-12 Adapter – OTT FAD 5
connecting kit".
■Disconnect the 4-pin plug connector (screw terminal strips) in the humidity
absorber. If the voltage supply to the OTT PLS-C is continuous (not switched),
the 2-pin connector can remain plugged.
■Connect the connecting cable of the connecting kit to the 4-pin plug in the
humidity absorber and to the OTT USB/SDI-12.
Note: If you do not use the connecting kit, the connection is made as shown in
Chapter 5.1 or 5.2 (variant in each case above; I ≤ 100 mA).

Depending on the variant of the OTT PLS-C
only one interface type (SDI-12 or RS-485)
is used. The "OTT USB/SDI-12 Adapter –
OTT FAD 5 connecting kit" still offers the
possibility to connect the wires of the inter-
face not in use to the screw terminal block

6 Install, start and operate software
In order to change the configuration of an SDI-12 sensor, you need the PC soft-
ware "OTT SDI-12 Interface" (SDI_Interface.exe) in addition to the USB/SDI-12
Adapter.
In addition, a special USB interface driver must be installed on the PC.
The setup files of the software and the USB interface driver are included on the
USB stick supplied at the factory. Alternatively, you can also find them on the
website "www.ott.com/resources" for download (free of charge).
Hardware and software requirements: Current standard PC with USB interface
(USB socket type A; desktop/tower version or notebook); operating system:
Microsoft Windows 10 or newer.
Installing the USB interface driver on the PC:
The USB interface driver must be installed once before using the "OTT SDI-12
Interface" software for the first time. For installation, the USB/SDI-12 adapter
must not yet be connected to the PC!
■Log on to the PC with administrator rights.
■If the setup file of the USB interface driver was downloaded from the internet
(file extension: ".zip"): Extract (unzip) the setup file.
■Start the setup file "CDMxxxxxx_Setup.exe" 1) ➝the "FTDI CDM Drivers –
InstallShield Wizard" opens 2).
■Follow the installation instructions on the screen.
■Then connect the USB/SDI-12 Adapter to the PC via the factory-supplied USB
connection cable ➝the PC completes the driver installation on its own.
Install and start software "OTT SDI-12 Interface"on PC:
■Log on to the PC with administrator rights.
■Start the setup file "Setup_SDI12Interface_Vxxxx_DE.exe" 1) ➝the
"OTT SDI-12 Interface – InstallShield Wizard" opens 2).
■Follow the installation instructions on the screen.
■If the USB connection cable was removed after installing the USB interface
driver: Reconnect the USB/SDI-12 Adapter to the PC via the USB connection
cable.
■Start the software "OTT SDI-12 Interface" (Windows Start menu | subdirectory
"OTT" | "SDI Interface") ➝the USB/SDI-12 Adapter is now ready for use; the
green/red LED on the USB/SDI-12 adapter must be continuously green.
Operating the software "OTT SDI-12 Interface":
The software has an integrated, context-sensitive online help. To get detailed infor-
mation on how to use the software, open a separate window with help topics:
■Select menu "?" | function "Help"or alternatively press "F".
1) „xxxxxx”; „xxxx”: current version number
2) if this file was downloaded from the Internet, a security warning will appear first
