6. ACCESSORIES
The instrument is equipped with a 5-pin TTL communica-
tions port that allows the connection of some accessories
described below.
6.1
Parameters configuration by “A01”
Through the 5 poles TTL port it is possible to transfer from
and toward the instrument the functioning parameters to the
A01
device.
This device it is mainly usable for the serial programming of
some instruments which need to have the same parameters
configuration or to keep a copy of the parameters setting of an
instrument and allow its rapid retransmission.
The same device allows to connect a PC via USB with which,
through the appropriate configuration software for “
AT Univer-
salConfig
”, the operating parameters can be configured.
To use the device
A01
it is necessary that the device or instru-
ment are being supplied directly or through the key.

ARS1 Serial Interface
Through the
ARS1
device (TTL/RS485 interface) and the
appropriate TTL cable is possible to connect the controller to
a RS485 serial communication network to which other instru-
ments are connected (controller or PLC), typically managed
by a personal computer used as plant supervisor.
Using a personal computer it is possible to acquire all the
function information and to program all the instruments con-
figuration parameters. The software protocol adopted for the
instruments is a MODBUS RTU type, widely used in several
PLC and supervision programs available on the market.
If the instrument is used in a RS485 network, use the param-
eter
AS
to set the station Address.
Note:
The baud-rate is fixed at 9600 baud.
ARS1 interface is directly supplied by the instrument.
