b.
Inputs. Machine has several input equipment which inform implement ECM of machine operating conditions.
Machine has inputs from switches and sensors. Switches provide an open, a ground, or a +battery to implement
ECM inputs. Sensors provide a constantly changing signal to implement ECM. Inputs into implement ECM are
listed in Tables 7 and 8.
c.
Outputs. Implement ECM responds to decisions by sending electrical signals through outputs. Outputs can create
an action or provide information to implement ECM. Implement ECM outputs are listed in Tables 7 and 8.
d.
Input/Output. CAT Data Link is used to communicate with other ECMs on machine. Data link is bidirectional,
both sending and receiving information. CAT Data Link allows information sharing with other ECMs. CAN Data
Link is used for programming application software into ECMs. CAN Data Link is bidirectional, both sending and
receiving information.
