3.16 TTL Level Position Compare Output
(PCI-1240U only)
This is a special design for the customers who can use the position com-
pare output to synchronize with other vision devices. For PCI-1240, the
position compare output channels are nOUT4 and nOUT5, and it is open-
collector type output. In which the nOUT4 and nOUT5 represent the
different direction of position compare separately. For PCI-1240U, we
provide an integrated option for the position compare output. By selecting
with JP10, you can choose the XOUT4 pin as original design as PCI-
1240, or TTL level output. While the JP10 is in “CMP” position, the
output of XOUT4 is (XOUT4 XOUT5). With this special design you can
get the compared result in both increment and decrement direction
through one unified pin.

The XOUT4 is defined as the pulse out-
put channel for the incremental position
compare mechanism. And it’s open-col-
lector type output. XOUT4, Pin 1 and Pin 2

It’s a design only for PCI-1240U. The
position compare signal for both
directions will output from XOUT4, and
the output level of XOUT4 is TTL level. CMP, Pin 2 and Pin 3 short
