Size 1.5FT

  • Connect RS-485/RS-422 devices directly to USB
  • FTDI FT232 chipset ensures reliable data conversion
  • 600 W surge and 15 KV ESD protection safeguards equipment
  • No external power supply needed for operation
  • Plug-and-play on Windows 11 10 8 7 and Mac

Industrial RS422 RS485 Converter

This USB to RS422 RS485 serial converter cable uses an FTDI FT232 chip to connect industrial equipment directly to a laptop or PC USB port. It suits engineers and technicians who need reliable half-duplex RS485 or full-duplex RS422 communication in factory or automation settings. The 1.5 ft cable length keeps the link short for noise immunity.

Built-in Protection and Indicators

The adapter provides 600w surge protection and 15KV ESD isolated protection on signal pins to shield sensitive control gear from electrical damage. LED troubleshooting indicators show link activity so you can verify the connection without extra tools. No external power supply is required and the design avoids IRQ and COM port conflicts on the host system.

Driver Support and Common Issues

The converter supports Windows 11, 10, 8, 7 and Mac with plug-and-play operation once the FTDI driver is installed. Installation is straightforward but users sometimes forget to match the RS485 half-duplex or RS422 full-duplex wiring to their device. Incorrect termination or missing driver installation are the typical causes of communication failure.

Questions about this item

Will the FT232 chipset or the USB connector need replacement after extended industrial use?

The adapter uses an FTDI FT232 chipset and requires no external power supply; it draws power from the USB port and has no user-serviceable parts, so no scheduled chip or connector replacement is expected.

What limits the cable length when running RS485 at full speed in a noisy factory?

The cable is 1.5 ft long; RS485 half-duplex operation with 15KV ESD protection and 600w surge protection is designed for industrial noise immunity, but the fixed 1.5 ft length is the physical limit of this adapter.

Does the adapter get hot or draw extra power when left plugged in all day?

No external power supply is needed and the FT232 chipset operates from the USB port; the supplier notes no IRQ or COM port conflicts and no mention of heat buildup during continuous operation.
