3.16 TTL Level Position Compare Output
This is a special design for the customers who can use the position com-
pare output to synchronize with other vision devices. For PCI-1220U, the
position compare output channels are nOUT0 and nOUT1, and it is open-
collector type output. In which the nOUT0 and nOUT1 represent the
different direction of position compare separately. For PCI-1220U, we
provide an integrated option for the position compare output. By selecting
with JP6, you can choose the XOUT0 pin as original design as PCI-
1220U, or TTL level output. While the JP6 is in “CMP” position, the
output of XOUT0 is (XOUT0 XOUT1). With this special design you can
get the compared result in both increment and decrement direction
through one unified pin.

The XOUT0 is defined as the pulse out-
put channel for the incremental position
compare mechanism. And it’s open-col-
lector type output. XOUT0, Pin 1 and Pin 2

It’s a design only for PCI-1220U. The
position compare signal for both
directions will output from XOUT0, and
the output level of XOUT0 is TTL level. CMP, Pin 2 and Pin 3 short
