QmBtn should show an array of 64 buttons like this...
If the board does not communicate with the PC make sure
that the O/P Select jumper is set to ‘RS232’ and cycle
power off and on again.
If the setups are correct, touching the key areas on the
panel will cause QmBtn buttons to depress. The last key
touched will leave an ‘X’ on the key afterwards.
Further details on QmBtn are found in the QmBtn user
guide and in the QT60645 datasheet.
Tip: Roll the flex circuit onto the panel starting from a short edge, first carefully lining
Adhere the supplied flex circuit to a plastic panel (one of each supplied).
Place 6 rubber feet (supplied) on the flex side of the plastic so that when the
completed panel is set onto a desk, it will be elevated and mechanically stable
(otherwise you will get wildly fluctuating signal levels when you press on the panel).
Attach the 9V battery snap or other power leads to the board’s power terminal block.
Place 4 rubber feet on the PCB so that it will be elevated and mechanically stable.
Plug the matrix tail into the 16-way in-line male connector the board. The matrix
panel should be flex side down so that you will touch the plastic panel, not the flex.
Connect the board to a PC using the RS232 serial cable (included). Make sure the
serial port is not being used by any other application or driver.
Run QmBtn on the PC (found on the supplied CD or from our website).
Apply +8 to +20VDC to the screw terminal block. This may be a 9V alkaline battery
or a bench supply.
The board should start communicating with QmBtn.
up the flex with the plastic. Roll the flex down onto the panel while using one
hand to smooth it on to eliminate air pockets. It helps to have a second set of
hands.
