The OE daughter card
i
s mounted on a standard I/O card. Th
i
s card takes the EIA-
4 2 2 A ser
i
a
l
encoder data and converts
i
t to 2 4 b
i
ts for use by the CPU. T w o CPLD’s
are emp
l
oyed to convert the buffered ser
i
a
l
data to para
ll
e
l
data for use by the CPU.
The card reads each encoder about 4 0 0 0 t
i
mes per second.
