USB to Serial RS422/485 Industrial Converters
These adapters enable you to add serial COM RS422/485 ports to your PC
Workstation or Embedded System, providing the ability to communicate between USB
(Universal Serial Bus) and serial peripherals.
They add Windows serial COM-ports via USB connection and are compatible with new
Windows OS and legacy RS422/485 devices.
This plug and play USB solution is perfect for mobile instrumentation and
applications requiring many RS422/485 devices. USB plug and play allows easy
serial port expansion that requires no IRQ, DMA or I/O port resources. Users no
longer need to power down the system and open the case, saving time and costs.
USB-S422
USB to Serial RS422/485 Communication Converter 1X 9 pin male
connector
Industrial serial ports on USB connect
RS-422 and RS485 devices, used in industrial environment. With RS-485 the data
direction is controlled by the port, without further action from the software.
The high speed serial port with the 128 byte FIFO allow high speed
communication, even in heavy loaded systems. Unique features reduce the system
load. The serial port also allows unusual speed settings like 500.000bps.
