Overview This is an industrial USB to RS232/485/TTL isolated converter with original FT232RL inside. It features embedded protection circuits such as power isolation, ADI magnetical isolation, and TVS diode, etc. Whats more, the USB TO RS232/485/TTL comes with an aluminium alloy enclosure, make it solid and durable to work. The USB TO RS232/485/TTL is very easy to use, fully automatic transceiving without delay. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipments and/or applications with high communication requirement. Features 1. USB TO RS232, USB TO RS485, USB TO TTL (UART) 2. Adopt original FT232RL, fast communicating, stable and reliable, better compatibility 3. Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal 4. Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption 5. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic 6. Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance 7. Fully automatic transceiver circuit with no delay, ensures the USB port communicates with different interfaces fastly and stably, without interfering each other 8. Onboard TTL serial 3.3V/5V voltage translator, config the TTL level via switch 9. Aluminium alloy enclosure with sand blasting and anodic oxidation, CNC process opening, solid and durable 10. 3 LEDs for indicating the power and transceiver status 11. High quality USB-B and RS232 connectors, smoothly plug/pull Specifications 1. Product type: industrial optically isolated converter 2. Baudrate: 300-921600bps 3. Host port: USB 4.
