FT232 USB To RS485 TTL Serial Converter Adapter Module

USB To RS485 Converter Introduction USB To RS485 Converter TTL Serial Adapter Module. The USB to RS-485 converter module introduce pairs a MAX485 RS-485 transceiver chip with an FT232RL USB UART IC to convert a USB stream to RS-485. It supports various devices with RS-485 communication interface like a Programmable Logic Controllers (PLCs). Below are its features, copy from an online seller’s page. Onboard chips: FT232RL & MAX485 Supports wide baud-rate of 300-9216000 bps Can also be use as USB to TTL & TTL to RS485 Converter Supports Windows 98, ME, 2000, XP, WIN7, Vista, Windows8, Windows10 No external power supply require (Power via USB Port) Supports multi-point communication Each converter allows up to 32 RS485 devices to be connect As you can see, the module is a very compact and ready to use piece of electronics. It performs the USB (Universal Serial Bus) to two wire RS485 (Two-Wire Half-Duplex) and vice versa conversion. The module holds an FT232RL USB UART IC with MAX485 to switch between the USB and RS-485 communication standards. USB To RS485 Converter About Note that the FT232RL is also link to the transmit and receive enable inputs of the . MAX485 to control the communication mode of the RS-485 transceiver. With the proper drivers (available for Windows, Mac and Linux) install, The FT232RL will enumerate as a virtual COM port (VCP) – See below. Note: A COM Port will only be assign to the USB to RS-485 converter module if the correct driver for the module has been install successfully. VCP Drivers Download Link https://ftdichip.com/drivers/vcp-drivers/ To put it simply, the FT232RL is configure in the standard way as USB to UART chip, and it drives the MAX487. RS-485 transceiver chip while the direction is control by the TXDEN pin. The USB port is a standard USB-B female connector and the RS-485 connections are made by a 3-way screw terminal connector. The Power status and Tx/Rx states are indicate by three onboard LEDs. The 4 jumper caps (5V/RX/TX/GND) simply link the USB interface to the RS-485 interface. If the jumper caps are removed, the FT232RL circuitry may be use as a standalone USB-TTL interface, and/or the MAX485 circuitry as a TTL-RS485 interface. en.wikipedia.org Categories: Arduino & Components, Converters, Programmers, Programmers & Microcontroller Tags: Adaptor Module, Converter, FT232, TTL Serial Converter, USB to 485, USB to RS485
