6 ACCESSORIES
The instrument is equipped with a TTL port with a 5 poles con-
nector that allows to connect some accessories.
6.1 Parameters Configuration by A01
Through the TTL port the instrument allows the transfer of the
functioning parameters to/from the device
A01
.
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.
