PUL+(+5V)
Pulse signal: Single pulse(pulse/direction) mode. 4-5V when PLU-HIGH,
0-0.5V when PUL-LOW. For reliable response, pulse width should be longer
than 1.5uS. Series connect resistors for current-limiting when +12V or +24V
used.

DIR
（
+5V
）
DIR signal: This signal has low/high voltage levels, representing two directions
of motor rotation; For reliable motion response, DIR signal should be ahead of
