Necessary instructions
- The serial port expansion box is a custom-developed serial port expansion peripheral developed by our company, which is convenient for expanding and accessing multiple 232or485 peripherals. Here, we take the expansion access of 485 temperature sensor peripheral as an example.
- The 12V/5V serial port box power input port supports a wide range of 5-12V levels, and you can choose 12V or 5V out power supply when connecting to the device.
- The output voltage of the serial port box is 5V, so the power supply for the expansion peripherals here is 5V power supply. If you need 12V power supply, you need to connect the 12V line of the device IO harness.
- For the device menu configuration parameters, see the "Model Corresponding Configuration Parameter Table" below. Model Corresponding Configuration Parameter Table
| Model | Serial Port Index | Serial Port Function | Protocol Type | Baud Rate |

Operation Steps
1. Wiring
Input wiring
Output wiring Refer to Temperature sensor configuration and use to connect to the 232 or 485 wiring harness of the serial port box output extension. For the detailed definition of the serial port box output harness, refer to the output interface definition below. ps: For connecting other peripherals, refer to "Serial port peripheral configuration" and other serial port documents to connect to the serial port expansion box output harness.
2. Device menu configuration
2.1 Remote control enters menu>>Settings>>Serial port settings>>Serial port, serial port index configures RS232, serial port function serial port box, other parameters are default, confirm and save.
2.2 Remote control enters serial port box configuration>>Serial port, serial port index configures EX-RS485, serial port function temperature sensor, other parameters are default, confirm and save and restart the device to take effect.
ps: To access other peripherals, refer to "Serial Port Peripheral Configuration" and other serial port documents. Configure the serial port or other IO, pulse and other extended functions in the serial port extension menu.
3. Test
After restarting, press the remote control direction key to go to the serial port status to check whether the serial port box and peripherals are connected
