Definition of Behaviour
SW1
1 & 2
Switches 1 and 2 set the CAN communication speed:
3 to 8
The logic address is composed by 2 elements: the module
identification and the hardware address. The module identification is
set on firmware and cannot be changed. The hardware address is
selected by switches 3 to 8, being 3 the least significant bit (LSB) and
8 the most significant bit (MSB):
ON
1 2 3 4 5 6 7 8
ON=1
OFF=0

SW2
BOOT0
Factory use.
Must be OPEN on operation.
SW3
RESET
Must be OPEN on operation. A temporary bridge causes a reset of the board.
SW4
CAN-END
Placing jumper adds a 120 Ohm resistor between the CAN-High and CAN-Low
signals of CAN-Bus.
