USB TO RS485
}}

== Introduction ==
This is an industrial USB to RS485 converter with original FT232RL inside. It features embedded protection circuits such as lightning-proof, resettable fuse, ESD protection, and TVS diode, etc. It's pretty small in size.

===Features===
*USB to RS485 communication
*Adopt original FT232RL, fast communicating, stable and reliable, better compatibility
*Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
*Onboard 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 status

===Specification===
*Product type: industrial converter
*Baudrate: 300-921600bps
*Host port: USB
*Device port:  RS485
*USB:
**Operating voltage: 5V
**Connector: USB-A
**Protection: 200mA self-recovery fuse, ESD protection
**Transmission distance: about 5m
*RS485:
**Connector: screw terminal
**Pins: A+, B-, GND

**Protection: 600W lightning-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 detected
**TXD: red TX indicator, light up when the USB port sends data
**RXD: red RX indicator, light up when the device ports send data back
*Operating environment:
**Temperature: -15℃ ~ 70℃
**Humidity: 5%RH ~ 95%RH
*Operating system: Mac, Linux, Android, WinCE, Windows 10 / 8.1 / 8 / 7 / XP

==User guide==

===Driver installation===
*Connect the module to host PC, check Device Manager, if the device is listed with the yellow exclamation mark, it means that the driver was not installed.
