! BCD Specifications
An Output is generated with each key press with a pulse duration
of 75 msec. If a longer pulse width is required, grounding the PINK
wire on the connector will increase the pulse width to 150 msec.
An annunciator beeps with each key press.
The output is BCD SINKING with internal 2.2K ohm pull-up
resistors. If a BCD SOURCING output is required, grounding the
ORANGE wire on the connector will convert the output to BCD
SOURCING thru 2.2K ohm resistors. The resistors are pulled up
to the internal 5V.
The BCD outputs are:
1 GREEN
2 WHITE
4 VIOLET
8 BLUE
! Position “0” is sent as a 10
