USB-to-DB9 serial cable with nine status LEDs, 3 ft

BFKK

BFKK USB to Serial RS232 DB9 Adapter Cable 9 LED PL2303GC 3ft

SKU CH-T0M7-AAGY9

USB-to-serial adapter with nine status LEDs and a Prolific PL2303GC chip for PLC programming and industrial equipment

  • Real-time port monitoring with nine status LEDs
  • High-speed serial data up to 921.6 Kbps
  • 512-byte FIFO buffer for reliable throughput
  • Prolific PL2303GC chipset ensures broad OS support
  • Shielded 3 ft cable with locking DB9 screws

USB to Serial RS232 Adapter for PLC

This cable converts a USB port to a DB9 serial interface using the Prolific PL2303GC chipset. It targets beginners and experts working with PLC programming, robot control, data acquisition, and embedded systems. The 3ft cable includes pre-installed DB9 screws for a secure connection to serial devices. Copper shielding reduces EMI/RFI interference for stable data transmission in noisy environments.

921.6 Kbps Maximum Baud Rate

The adapter supports a maximum baud rate of 921.6 Kbps and a 512 byte FIFO buffer for efficient data handling. It handles 5, 6, 7, or 8 data bits with odd, even, mark, space, or none parity modes. This specification suits legacy industrial equipment, networking gear, and console ports that rely on standard RS232 signalling. It will not serve applications requiring higher throughput or modern high-speed serial protocols.

Nine Status LEDs and Broad OS Driver Support

Nine built-in LEDs provide real-time visual monitoring of port activity, simplifying troubleshooting for both novice users and IT professionals. The PL2303GC chipset (VID_067B&PID_23A3) is compatible with Windows 11, macOS 15, and Linux without requiring separate driver hunts. The bundle includes no extra software beyond the standard OS drivers, so workflow changes only through the immediate diagnostic visibility the LEDs add.

Questions about this item

Will the 921.6 Kbps maximum baud and 512 Byte FIFO buffer work with my older PLC that only supports lower standard rates?

The adapter supports 5, 6, 7 or 8 data bits and multiple parity modes, so it can match the PLC's serial settings; the higher maximum simply means it will not limit the connection.

How do I confirm the PL2303GC chip is communicating after I plug the cable in?

The nine status LEDs show real-time port activity — transmit, receive and handshake lines — giving immediate visual confirmation that data is moving.

Does the 3 ft cable include the DB9 screws and driver media, or must I buy them separately?

The DB9 screws are pre-installed on the connector; drivers for Windows 11, macOS 15 and Linux are downloaded from the chip vendor, so no separate media is needed.
