Titan Atrato 710, Instruction Manual

Page: 6 / 22

The Atrato can be operated entirely from a computer using the USB connection but this
may not be acceptable in many situations where remote operation or further functions
are required. The unit will work with systems from Windows XP onwards. The maximum
connector cable size is 2.5mm (22-14AWG), for ease of assembly we recommend 1mm
maximum. Care should be taken when terminating the wires as the conductors should
be stripped to 4 to 5mm maximum and the wire ends must be pushed fully into the
connector before tightening. These cables pass through a slot cut in the aluminium
housing please ensure that no bare conductors are clear of the surface of the connector
strip prior to closing the housing.
