You can configure the baud rate using the red DIP switches on the module board. Refer to the specific product manual for the switch combinations (e.g., 9600bps or 19200bps). The settings take effect only after the device is restarted.
Most Foshan Qingjun Electronics modules utilize the standard Modbus-RTU protocol for communication over RS485 or RS232 interfaces.
The default communication timeout is typically set to 10 seconds. This can correspond to a register value (e.g., 0x2710 in hexadecimal) and can often be adjusted via the timeout registers.
For the PT100 temperature acquisition module, the actual temperature is usually the collected integer value divided by 10. For example, a reading of 255 (0x00FF) corresponds to 25.5°C.
Yes, settings such as the hardware address configured via DIP switches and certain register values like timeout settings typically utilize power-off memory saving.
