2. Installation
2.1 Dimension drawings
The shell size of the GCAN-202 is shown in Figure 2.1.
Figure 2.1 Dimension drawings
2.2 Connect to PC
Connect the converter to the computer with a network cable. Then GCAN-202 LAN
interface can establish communication.
2.3 Connect to CAN-Bus
In practical use, most of the time just connected the CAN_H to CAN_H and CAN_L
connected to CAN_L, then communication can be realized.

3. converter used
GCAN-202 converter uses a network cable to connect to PC, uses +9 ~ 30V DC
power supply(recommended + 12V or + 24V power supply), uses the "CANet
Config" software to configure.
3.1 Restore the factory settings
Default IP of GCAN-202 is 192.168.1.10, gateway is 255.255.255.0. If the user has
modified the IP and forget it. By pressing the reset button, you can restore the factory
settings.
After GCAN-202 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.
Figure 3.3 GCAN-204 connection to other CAN converter
Please note: you should connect the two ends of the resistor to CAN_L and
CAN_H respectively.
3.4 Indicator light
GCAN-202 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.
