The following wiring diagram is for OUT and DIR signals on the 2
axes.
PCI-8102:
NOTE: If the pulse output is set to open collector output mode,
OUT- and DIR- are used to transmit OUT signals. The sink current
must not exceed 20mA on the OUT- and DIR- pins. The default
setting of jumper is 1-2 shorted. The default setting is 1-2 shorted.
Suggest Usage: Jumper 2-3 shorted and connect OUT+/DIR+ to a
470 ohm pulse input interface’s COM of driver. See the following
figure.
Warning: The sink current must not exceed 20mA or the 26LS31
