5.3.3
Piezo Driver Hub Mounting Options
When the T-Cube NanoTrak and two Piezo Drivers are used together on the hub,
signals can be routed via dedicated internal communication channels. These
channels are selected via the piezo unit settings panel, or via the ‘MODE’ button on
the top panel of the unit.
If Channel 1 is selected, the feedback signal runs through all the bays. If Channel 2
is selected, the feedback signals run between adjacent pairs of T-Cube bays (i.e. 1
and 2, 3 and 4, 5 and 6) - see Fig. 5.5.
Fig. 5.5 Hub Analog Input Channels
Only certain NanoTrak and piezo cube arrangements allow the system to function
correctly. Furthermore, the setting for the
Analogue Input Source (EXT IN)
parameter
in the piezo settings panel, depends on the bays in which the piezo and NanoTrak
units are fitted. The various bay options, and their associated
Analogue Input Source
(EXT IN)
settings are described in Fig. 5.6.
5.3.4
Wiring and Software Settings for Standalone Operation
Using the KCH hub greatly simplifies system wiring because the hub provides all the
necessary power, signal and USB comms connections to all controller cubes.
However, for certain applications it may be convenient to set up the system without
using a hub, with hard wired electrical connections via the rear panel terminals and
power supply and USB connections for each individual unit.
In this case, the procedure is as detailed in Section 4.3.1. but the ‘
Analogue Input
Source (EXT IN)
parameter in the piezo settings panel should be set to
‘SMA Input
’.
