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

Position "*" is sent as an 11
