BOARD PREPARATION
Before powering up, prepare the matrix panel and board using the following steps:
1
Place the panel on a bench so that it will be elevated and mechanically stable, otherwise you will
get wildly fluctuating signal levels when you press on the panel.
2
Attach the 9V battery snap (or other power leads) to the board's power terminal block.
SETUP
After you have prepared the board and matrix, get the unit to run as follows:
1
Plug the matrix tail into the board's matrix connector. The matrix panel should be flex-side down
so that you touch the plastic panel, not the flex.
2
Connect the E6486 to a PC using the RS232 serial cable (supplied). Make sure the serial port is
not currently used by any other application or driver (like mouse software) and there are no Com
conflicts. The board will work on Com 1 or Com 2.
3
Run the QmBtn™ software (on the supplied CD or from www.qprox.com/downloads).
4
Apply +8 to +20VDC to the screw terminal block. This can be a 9V alkaline battery or a bench supply.
5
The board should start communicating with QmBtn™, and you
will see an array of 48 buttons as shown on the right.
If the board does not communicate with the PC, make sure the jumper
J4 (located next to the power connector) is set on 'UART', then cycle
power off and on again.
If the setups are correct, touching the keys on the panel will cause the
QmBtn™ buttons to depress. The last key touched will leave an 'X' on
the key afterwards. You can open the 'Key Settings' window and look at
the signals from any specific key by clicking with your mouse on the key
representation. You can change the settings for the chosen key or all
keys using the 'Key Settings' window. You can also view all 48 signals
in bar graph form in the 'Signal Levels' window.
