3. converter used
GCAN-211 converter uses a network cable to connect to PC, uses +9 ~ 30V DC
power supply(recommended + 12V or + 24V power supply), uses the "GCAN-211
Config" software to configure.
3.1 Restore the factory settings
GCAN-211 WiFi default IP: 192.168.1.11,If the user has modified the IP and forget it.
By pressing the reset button, you can restore the factory settings.
After GCAN-211 is powered on, you can find the reset button as shown above. Then
press the button for about 5-6 seconds. When the indicator flashes, the system is
restored successfully.
Please note: PC and GCAN-202 must be in the same network segment.
3.2 The structure of CAN-Bus
This is CAN-Bus connection, as shown in figure 3. 2.
Figure 3.2 Topology structure of CAN-bus
3.3 Termination resistor
CAN-Bus requires two 120Ωtermination resistors in the furthest of the two
terminals, as shown in figure 3.3.

Please note: you should connect the two ends of the resistor to CAN_L and
CAN_H respectively.
3.4 Indicator light
GCAN-211 converter has one PWR indicator, one SYS indicator, one LAN indicator,
two CAN indicator, to indicate the converter status. More functions are shown in table
3.2.
