Overview
USB TO 4CH RS485/422 is an industrial grade USB to RS485/422 isolated converter with original FT4232HL, onboard protection circuits such as built-in power isolation, ADI magnetical isolation and TVS, and aluminum alloy case design, which is suitable for industrial devices and applications with high communication requirements.

Features
Adopts original FT4232HL chip, fast communicating, stable and reliable, better compatibility
Supports USB to 4-ch multi-functional serial port, convenient for expanding or debugging various industrial serial port devices
Supports USB to 2-ch isolated RS485/422 + 2-ch isolated RS485
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
9 LEDs for indicating the power and transceiver status
High quality USB-B connectors, smoothly plug/pull
Industrial grade metal case, supports wall-mount and rail-mount installation, solid and beautiful, easy to install
