About product
Features
Compatible with RS232/RS485 standard, it can convert RS232 signal to balanced difference RS485
signal.
Stable transmitting rate, supports baudrate 300~115200bps
Integrate unibody power supply isolation, stable isolated voltage is provided, need no extra
power supply for the isolated terminal
Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong
anti-interference, low power consumption
Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong
anti-interference, low power consumption
Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong
