1.6.5 Galvanic Decoupling
The CAN-Bus connection is opto-electrically decoupled. The ethernet connection is
magnetically decoupled. The electrical strength of both decouplings is greater than
500 Volts DC.
1.6.6 Propagation Delay
The propagation delay is the time the EC10 needs to convert an ethernet packet into
a CAN-Bus packet and vice versa. This time is approximately 190 microseconds in each
direction. The run-time of the ethernet packet (approximately 50 microseconds) adds
to this time.
