Links 3 & 4
The outputs from counter 1 and 2 can be connected to the D-50 connector using LK4 and 3
respectively.
NOTE: The counter outputs are interfaced to the I/O connector using an inverting open-collector
driver. The output state is therefore the inverse of the counter output state defined in the data
sheet. When using the counter outputs, it is necessary to ensure that the I/O signals for group 2,
bits 0 and 1, are set for input mode by writing '1's to both bits. This avoids the counter output
conflicting with the I/O port output.
