CANSwitch-AF2S2
High-Performance Dual-CAN to Fiber Switch User Manual
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.
