Elecbee PL2303 USB-A to DB9 Male RS232C Serial Adapter Cable 1.8m COM Port Converter

Elecbee PL2303 USB-A to DB9 Male RS232C Serial Adapter Cable

The Elecbee PL2303 USB-to-RS232C adapter cable converts a compatible computer USB-A port into a DB9 male serial connection. Once the appropriate driver is installed, the cable creates a virtual COM port for communication with compatible legacy, retail and industrial RS232 equipment.

The approximately 1.8m cable provides practical reach between a computer and connected equipment. Compatibility depends on the PL2303 revision, operating-system driver, DB9 pinout and serial communication settings.

Unspecified Parameters: The baud-rate range, exact DB9 pinout, PL2303 revision and connected handshake lines have not been supplied. These specifications should not be assumed.

Virtual COM-Port Operation

The adapter converts USB communication into RS232C serial communication. After successful driver installation, the operating system assigns a virtual COM-port number that can be selected in compatible serial or equipment-control software.

The user must configure the baud rate, data bits, parity, stop bits and flow-control mode required by the connected equipment. The cable does not automatically determine every device communication setting.

Flow Control and Power Management

Supported PL2303 variants provide hardware and software flow-control capabilities, USB power management and configurable remote wake-up.

These chipset capabilities do not guarantee that every corresponding DB9 signal is connected in the finished cable. Operation depends on the exact PL2303 revision, internal cable wiring, driver configuration and connected device.

Driver and System Compatibility

The supplier lists Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10, Mac OS and Linux compatibility. However, support differs among PL2303 hardware revisions and operating-system builds.

Windows may download a compatible driver automatically for some chip and system combinations. Automatic installation should not be treated as guaranteed driver-free operation. If the cable is not detected, identify the chip revision when possible and install the corresponding driver.

Application Examples

The adapter can connect compatible cash registers, scanners, fiscal-control equipment, programming devices, handwriting tablets, touchscreens, access-control systems, CNC machines, temperature controllers, industrial instruments, barcode printers, external modems, LED displays and industrial computers.

Before ordering, confirm that the equipment uses RS232C electrical levels, has a compatible DB9 female port and supports the cable’s wiring arrangement.

Connection Instructions

Step 1: Confirm that the target device uses an RS232C DB9 female interface.
Step 2: Determine whether straight-through or null-modem wiring is required.
Step 3: Install the appropriate PL2303 driver if necessary.
Step 4: Connect the USB-A plug to the computer.
Step 5: Connect the DB9 male plug to the serial equipment.
Step 6: Select the assigned COM port and configure the required serial settings.
