Pt1000 3-wire / Pt100 3-wire and 4-wire: For appropriate cable
resistance compensation they should be equal for all legs. Maximum
wire resistance is 25
Ω
per wire leg. Usage of a 3 or 4 wire with
conductors of equal length and gauge is recommended.

CONFIGURATION
When the trasmitter is used with the factory setting, no further action
is required and the transmitter is ready to be installed.
Changes to the configuration are possible through the TxConfig II
software or the TxConfig application, provided free of charge.
The TxBlock-USB Setup Kit consisting of the TxConfig II software and
USB cable can be purchased from the manufacturer or any authorized
distributor.
The software is continuously updated and new versions can be
downloaded at no charge from the manufacturer’s website. To install,
execute the
TxConfigIISetup.exe
file and follow the instructions.
The setup application is only available for Android smartphones and
also can be downloaded for free in the Google Play Store. To configure
the device through the application, an
On The Go
(OTG) adapter is
required. The procedure for using this adapter will be explained
throughout this manual.

During the setup, the transmitter is powered by the USB, not
requiring an external power supply.
The transmitter setup can also be made by connecting it to the loop,
using the
loop
power supply. There is no electrical insulation between
the transmitter and the communication port (interface), therefore it is
not recommended to configure it with the sensor inlet connected to the
process. See Fig. 9.

After these connections, the user must run the TxConfig II software
and, if necessary, consult the
Help
topic to help using the software.
For more information on how to connect the TxBlock-USB to the
smartphone itself and to configure the device, see chapter
SMARTPHONE CONNECTIONS.
The USB communication port (interface) of the
TxBlock-USB is not electrically insulated from the
transmitter’s input.
