ftdi rs422 serial db9 adapter

Specifications

ftdi rs422 serial db9 adapter details:

As the PC industry continues to evolve, USB interface is gradually replacing the old PC for low-speed peripheral interface, but the current environment, many important devices still use RS-232 interface design, so that many users use USB to RS-232 converter device to PC and RS-232 data transmission between devices.

HU-01 is a universal USB/RS-232 converter, no external power supply, compatible with USB, RS-232 standard, the ability to convert single-ended USB signals to RS-232 signal converter with zero delay automatic transceiver conversion, unique I / O circuit automatically controls the direction of data flow, plug and play. ensure that it meets all existing communications software and interface hardware.

HU-01 interface converter for point to point, the data communication speed 300-460800bps, with a power indicator light and data traffic indicator light to indicate a fault condition, supports communication with a USB to RS-232 converter.

Main function

HU-01 USB converter supports the following communication:

1. point to point communication

Hardware installation and application

Installing HU-01 USB converter before carefully read the product manual, product communications cable into the computer USB port USB interface port, this product USB/DB9M, universal connector for the input / output interface, RS-without setting automatically 232 communication mode, you can use twisted pair or shielded cable, connectivity, removal is very convenient. Converter for 9-wire, DCD RXD TXD DTR GND DSR RTS CTS RI full signal connection
