6 ACCESSORIES
The instrument is equipped with a TTL communication port
with a 5-pole connector that allows the connection of some ac-
cessories described below.
6.1
Parameters Configuration by A01
Through the TTL port and the
A01
device equipped with
a 5-pole connector it is possible to transfer the operating
parameters to and from the instrument.
This device it is mainly usable for serial programming those
instruments that need the same parameters configuration or
to keep a copy of the parameters setting of an instrument and
allow its fast duplication.
The same device allows to connect a PC via USB with which,
through the appropriate configuration software for “
AT Univer-
salConf tools
”, the operating parameters can be configured.
To use the
A01
device it is necessary that the device or instru-
ment are being correctly supplied.

6.2
RS 485 Serial Interface by ARS1
Through the ARS1 device (TTL/RS485 interface) and the ap-
propriate TTL cable, it is possible to connect the instrument to
a serial communication network (RS485 type) to which other
instruments (controllers or PLC) are connected, all depending
typically on a Personal Computer used as plant supervisor.

Using a Personal Computer it is possible to acquire all the
functionning data and program all the instrument configura-
tion parameters.
The software protocol adopted for the instrument is a
MOD-
BUS-RTU
type, widely used in several PLC and supervision
programs available on the market (Y and Z series protocol
manual is available on request).
