The functions of the connectors and interfaces in the diagram are described below.
A) CN2: Control circuit connector
If the manual control add-on board is being used, it plugs into this connector.
If the driver board is being used without the manual control add-on board, then the input
pins that need to be connected to control the MDL are pins 1, 2, 3, and 8. Output pins 4
and 5 can be used to monitor the status of the limit sensors. Pin 7 is a +5V power supply
for the manual control add-on board. It does not need to be connected if the manual
control board is not being used.
