6.2 Parameters configuration by AFC1
The AFC1 is a contactless NFC ( N ear F ield C ommunica-
tions) connection device that allows to Upload/Daownload
the operating parameters From/To the instruments.
The
AFC1
is powered directly by the
USB
port through
which is connected to a
PC
.
When an instrument is equipped with the NFC communication
option its operating parameters can be set through a common
Personal Computer and the “
AT UniversalConf ” program.
Once the changes have been made, the parameters can be
sent to the instrument using the
AFC1 device.
To load the operating parameters in the instrument using the
AFC1 device, place the instrument on the AFC1 with the dis-
play facing the NFC symbol ( ), then send the parameters
to the instrument’s memory.

6.3 Remote display “TVR Y”
The TVR Y remote display device can be connected to the
instrument via the appropriate cable, which can have a maxi-
mum length of 10 m. The TVR Y device, powered directly by
the instrument, displays the temperature measured by the
Pr1 probe using a 2 ½ digit display.

Through the ARS1 device (TTL/RS485 interface) and the
special TTL cable it is possible to connect the instrument to
a RS485 serial communication network in which other instru-
ments (controller or PLC) are inserted and typically referred
to a Personal Computer used as a system supervisor.
Through the PC it is therefore possible to acquire all the op-
erating data and to program all the configuration parameters
of the instrument.
The software protocol adopted by the instrument is of the
Modbus RTU type widely used in many PLC and supervision
programs available on the market.
If the instrument is used in an RS485 network, program the
station address to the
tAS
parameter.
The baud-rate of the serial port can not be set and is fixed at
the value of 9600 baud.
The ARS1 converter is powered directly from the instrument.
