Features: Adopting FT232RNL and SP485EEN chips, providing better stability and compatibility. On board integrated power isolation can provide stable isolation voltage without additional power supply at the isolation end. On board integrated digital isolation, capable of signal isolation, high reliability, strong anti-interference, and low power consumption. On board TVS (transient voltage suppression tube) can effectively suppress surgevoltage and transient peakvoltage in the circuit. The lightningand antistatic board carries self recovery fuses and protectivediodes, ensuring stable output of current and voltage, preventing overvoltage and improving impact resistance. The USB signal can be converted into a balanced differential RS485/422 signal, with a stable transmission rate and a transmission distance of about 1200meters from RS485/422 and about 5meters from USB. Multiple system compatibility, supporting MacLinux, Androids Win11/10/8.1/8/7 and othersystems.
