Instruction book, IQAN-MD4
Communication
The communication interfaces are used for uploading/downloading applications,
connecting to expansion modules, connecting to cameras or diagnostics.
CAN related functions
The IQAN-MD4 uses a CAN-bus (CAN = Controller Area Network) to communicate
with IQAN expansion modules and other systems. The CAN-bus is a robust
communication protocol that is widely used and well proven within the automotive
industry. The unit has four (4) CAN buses, CAN-A thru CAN-D. The buses may be
configured using IQAN software to be ICP (ICP = IQAN CAN Protocol), SAE J1939
or Generic user defined CAN protocol (e.g. CANopen).
Any of the CAN buses may be used for communication and diagnostics. A compatible
CAN communication card is required to be installed in your PC to use this feature.
Ethernet
The MD4 has two Ethernet communication ports, A (C3) and B (C4).
Port A is used for uploading/downloading applications and diagnostics and is
designated for computer communication. see Ethernet diagnostics communication for
more information.
Port B is used for in-vehicle network over Ethernet, for example communicating with
camera or other masters. see Video input for more information on how to use cameras.
