LORDWORLD USB to RS232/485 Converter FT232RNL

SKU CH-QK2P-JJW4S

A USB to RS232/485 serial converter with an original FT232RNL chip, onboard TVS protection, self-recovery fuse, switchable 120R termination and status LEDs in an ABS case

  • Reliable serial communication with original FT232RNL chip
  • Surge and static protection via onboard TVS diodes
  • Over-current and over-voltage safeguards with self-recovery fuse
  • Switch-selectable RS232 or RS485 modes with 120R termination
  • Power and data status visible through three indicator LEDs

USB to RS232/485 converter for industrial links

This LORDWORLD converter bridges a USB host to RS232 or RS485 serial buses using an original FT232RNL chip. It suits engineers, integrators and hobbyists who need reliable wired links to PLCs, sensors, modems or legacy equipment. The board selects between the two protocols with an onboard switch and fits inside an ABS protection case.

Check host OS and physical port before ordering

The device supports Windows 11, 10, 8.1, 8, 7, Linux, Android and Mac, so verify your operating system appears in that list. Ensure you have a free USB port and that the target equipment uses RS232 or RS485 signalling with compatible voltage levels. The 120R termination resistor on the RS485 side can be enabled or disabled by switch to match the bus topology.

Surge protection and status LEDs aid long runs

Onboard TVS diodes suppress surge and transient spikes on the RS232 line, while a self-recovery fuse and protection diodes guard the RS485 path against over-current and over-voltage events. Three LEDs show power and transceiver activity, letting you confirm link health during extended sessions. The ABS case shields the electronics in cabinet or field deployments.

Questions about this item

What comes in the box and do I need any extra cables for the RS232 or RS485 connections?

The converter includes the USB-to-serial unit in an ABS case with a built-in mode switch, 120R termination toggle and three status LEDs; RS232 and RS485 wiring terminals are on-board so you only supply your own field cables.

Should I pick the RS232 or RS485 mode for a 120-ohm bus?

Slide the selector to RS485 and enable the onboard 120R termination switch; for point-to-point RS232 leave the resistor disabled and set the switch to RS232.

What does the FT232RNL chip actually give me on Windows 10 or 11?

The original FT232RNL provides driver-supported virtual COM ports on Windows 10 and 11 with hardware flow control, surge-protected RS232 lines and fused RS485 outputs for stable industrial communication.
