Tip: After default settings are restored, all current configurations will be lost. Operate
with caution.
2.5 Fiber Interface
Figure 2.7 shows the appearance of the optical fiber (SC) interface of
CANSwitch-AF2S2, with four indicators. The Link indicator is green, indicating whether
the optical fiber network is physically connected. If it is connected to the optical fiber
network, the Link indicator is always on; the Active indicator is yellow, indicating whether
there is data transmission. If the optical fiber network has data transmission, the Active
indicator flashes.

2.6 CAN Port
The CANSwitch-AF2S2 device has two CAN ports. Figure 2.8 shows its appearance.
It has two indicators: CAN0 and CAN1. When a device is connected, when there is data
communication; Table 2.1 describes the pin definition.

Signal
Introduction
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.
