• Industrial USB to 4-ch Serial Converter, supports USB to RS232/485/422/TTL, supports USB to 1-ch TTL + 1-ch TTL/RS485 + 1-ch isolated RS485/422 + 1-ch isolated RS232/485. Adopts original FT4232HL chip, fast communicating, stable and reliable, better compatibility.
• Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal. Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption.
• Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & ESD protection. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance.
• Fully automatic transceiver circuit with no delay, ensures fast and stable communication between the USB port and different interfaces, without interfering with each other.
• Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch. 9 LEDs for indicating the power and transceiver status. Supports Mac, Linux, Android, Windows 11 / 10 / 8.1 / 8 / 7, etc.
