USB to RS485 communication,Adopt original FT232RL, fast communicating, stable and reliable, better compatibilityOnboard (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, For interface-proof & anti-electrostaticOnboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock resistance,3 LEDs for indicating the power and transceiver statusThe USB TO RS485 is very easy to use, allows automatic transceiving. Due to its fast communication, stability, reliability, and safety, it is an perfect choice for industrial control equipments and/or applications with high communication requirement.This is an industrial USB to RS485 converter with original FT232RL inside. It features embedded protection circuits such as For interface-proof, resettable fuse, ESD protection, and diode, etc. It's pretty small in size.Product type:industrial converterBaudrate:300-921600bpsHost port:USBDevice port:RS485USB:Operating voltage:5V ,Connector:USB-AProtection:200mA self-recovery fuse, ESD protectionTransmission distance:about 5mRS485:Connector:screw terminalPins:A+, B-, GNDDirection control:hardware automatic controlProtection:600W For interface-proof and surge-suppress, 15KV ESD protection (onboard 120R balancing resistor)Transmission distance:about 1200m (low rate)Transmission mode:point-to-multipoints (up to 32 nodes, it is recommended to use repeaters for 16 nodes or more)LED indicators:PWR:red power indicator, light up when there is USB connection and voltage is detectedTXD:red TX indicator, light up when the USB port sends dataRXD:red RX indicator, light up when the device ports send databackOperating environment:Temperature:-15 ~ 70Humidity:5%RH ~ 95%RH:, Linux, Android, WinCE, 10 / 8.1 / 8 / 7 / XPName:Demo Board Type: ARMModel Number: USB TO RS485colour:blackMaterial:ABSPackage Contents:1 * USB TO RS4851 * USB-A male to female cable1 * ScrewdriverOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
