CANL
CANL signal terminal of CAN
FGND
Terminals for connecting the CAN channel to the
shielding layer
CANH
CANH signal terminal of CAN
R-
120-ohm termination resistor of CAN. Connecting
the wire to R+ means enabling the internal
termination resistor
R+
120-ohm termination resistor for CAN. Connecting
the wire to R- means enabling the internal
termination resistor
Tip: The terminal resistance can be configured if R- and R+ are short-circuited with wires.
2.7 LED Indicator
The CANSwitch-AN2S2 device has six indicators, PWR, SYS, LAN0, LAN1, CAN0,
and CAN1, as shown in Figure 2.9.
