Connect the components. The reason for making these connections at this time is two fold. First it allows
the system to be verified functionally. In the event there was shipping damage, or some other issue, it’s
best to detect problems now instead of after the system is secured in place. Secondly, there is a green
LED light on each of the 22 note key scan boards. These LEDs are easily visible when the system is
powered on and they will aid you in the mechanical alignment of the key scan boards to the keys.
4. Connect the 6-Pin Flex cable coming from the Treble Connector of Key Scan board 4 (Step D-6 Figure 8)
to the Key Scan socket of the Soft Pedal Circuit Board.
See Figure 11.
5. Connect the 10-Pin Flex Cable to the Primary Port of the TUSB interface and to the IN socket of the Soft
Pedal Circuit board.
6. Power ON the QRS Sound Module (comes with 9V adapter) and connect it to the Serial I/O port
OR
connect the 5V AC Power Adaptor to the 5VDC socket of the TUSB interface.
DO NOT CONNECT BOTH!
When the AC adaptor or the QRS Sound Module is plugged into an AC outlet, the PNOscan
II
system
should power on. You will notice various lights blinking.
1. Grand - Remove the action stack from the key frame.
Do not remove the keys.
2.
Lay the Key Scan Assembly across the width of the keys
and up against the backs of the sharp keys.
See Figure 10.
3.
Position the metal Key Scan Track Assembly so that
there is an equal amount of over-hang, or under-hang, at
the bass and treble ends of the keyboard. Slide the
assembly against the sharp keys and use a few pieces of
masking tape to temporarily hold the assembly to the
keyboard during the circuit board alignment.
You will now establish the proper spacing of the Key Scan Boards for your particular piano. The process
we will use to establish this Left/Right alignment will also include an initial bench type functional test
which verifies proper system function, as it is ideal to test the components prior to installation.
