MOD-100-C, Type-C USB to RS485 adapter with 3 pin screw terminals

MOD-100-C, Type-C USB to RS485 adapter with 3 pin screw terminals

Product Specification:

• Equipped with three LED indicator lights: RXD, TXD, and power supply serial input protection.
• The chip features a swing rate driver program designed to minimize EMI and reduce signal reflections caused by improper terminal matching cables, resulting in an error-free signal transmission rate of up to 500Kbps.
• The receiver input impedance, with a 1/4-unit load, supports multi-machine communication and allows connection on the bus of up to 128 devices.
• Industrial-grade chips can operate at temperatures ranging from -40 ℃ to +85 ℃.
• This module supports hot swapping without experiencing the signal jamming phenomenon that occurs with other 485 chips during hot swapping.
• Additionally, it features a 120 Ω terminal resistance for increased stability and reduced error rates when the line length exceeds 200 meters.
• It utilizes transient suppression TVS 600W diode for enhanced overvoltage protection performance.
• Incorporates a 10 Ω current protection resistor. The SMT design improves the integrity of the 485 signals.
• RS485 and TTL signals are all wired on one side to ensure signal quality and improve signal integrity.
• Moreover, a large area copper laying is implemented to prevent signal interference.
• The module supports multiple baud rates: 300/600/1200/2400/4800/9600/19200/38400/57600/115200/230400/460800/921600.

Additional Notes:

• For Android phones, please ensure that your model supports OTG function. Currently, more than 90% of mainstream Android phones have OTG function.
• To facilitate development, provide Android source code and APK files compiled using the new version of Android Studio, and Eclipse projects. In case of compilation errors, please search for the error keyword yourself, as most issues are related to configuration or Gradle problems. Ensure that the project directory does not contain Chinese characters, as they may lead to errors.
• To test the development board, utilize Android serial port debugging tools. Simply connect the development board to debug the serial port, eliminating the inconvenience of using a computer. These tools are available for download on the cloud drive. The coding is adjustable and supports Chinese.
