Controller Area Networks(J1939), or CAN's are multiplex data systems. Multiplexing allows multiple data signals to travel on the same wires, integrating separate electronic systems and applications to a single point control and monitoring system. Using signals sent over a serial network, CAN systems provide instantaneous monitoring of diagnostic & control systems allowing early detection of potential problems.
Types of J1939's:
| J1939/11 |
A 3-wire system that uses the TE Deutsch DT series connectors primarily for truck and bus industries. |
| J1939/12 |
A system that requires the TE Deutsch DT series, HD30 series and ISO Box (HDBox). This group of electrical interfaces terminates a CAN between the tractor & its implement.
|
| J1939/13 |
| A system that uses the TE Deutsch HD10 series connectors for on-board diagnostics. |
| J1939/15 |
| A 2-wire system that uses the TE Deutsch DTM series connectors. |
