3.1.3
I/O Signal Connector (CN1) Pin Arrangement
The following figure gives the pin arrangement of the of the I/O signal connector (CN1) for the
default settings.
When you use line-driver high-speed outputs, wire the outputs to CN1-17 and CN1-18 and to
CN1-21 and CN1-22. When you use photocoupler normal outputs, allocate the output signals
for triggers at preset positions as normal and wire the outputs to CN1-1 and CN1-2, CN1-23
and CN1-24, or CN1-25 and CN1-26.
The above view is

of the following

connector shell
attached.
