3. CANBlue config software
3.1 Configuration
Disconnect the GCAN-203 power supply. We can connect to GCAN-203 and
computer with USB. When GCAN-203 is configuring, no external power is required.
GCAN-203 factory setting: CAN-Bus baud is 250K, working mode is normal mode,
name is SN number, password is 1234.
3.2 Software connection
Open "CANBlue Config" software in the "②CANBlue 模块配置软件" document to
configure the converter. Click "Connect" to connect the converter. The connection is
shown in figure 3.1.
You can click "UpLoad" to upload the parameters in the converter to your computer.

The user can set the GCAN-203's name and connection password. GCAN-203's
default name is SN number, password is 1234.
3.5 End of configuration
Click "Download" to write the configuration data to the converter's flash, as shown in
figure 3.6.
Figure 3.6 Download successful
The pop-up dialog displays "download Param success". Then power-on again. The
new configuration can take effect.
Note: The converter must be power-on again, otherwise the configuration will
not take effect.
3.6 Save the configuration file
Click “SaveAs” to save the configuration parameters to the PC. The file can be
opened again.
3.7 Open the configuration file
Use the “OPEN” function to open the configuration file and modify it. Then you can
click DownLoad to the converter that the new configuration can be saved.
Note: The working mode of “BlueTooth Test” and “CAN Test” is used for testing .
These functions cannot be used.

4. Application examples
4.1 Equipment wiring
GCAN-203 uses 9-30V DC power supply.
Connect CAN_H to CAN-Bus CAN_H, CAN_L to CAN-Bus CAN_L. A High-speed
CAN bus must be terminated on both ends with 120 Ohms. Otherwise disturbances
may arise.
Figure 4.1 The wiring diagram of GCAN-203
As shown in figure 4.1, the left side of the equipment is USBCAN-II Pro. Wiring and
termination resistance must be confirmed correctly. Open USBCAN-II Pro equipment
with ECANtools software, then select the baud rate to 250K.
4.2 Bluetooth connection
Install "CANBlue.RSO.apk" APP to a mobile phone with android which is in the "③
安卓系统串口助手安装包" document. Search for Bluetooth equipment, then enter
the connection password.
