USB 2.0 to DB9 serial adapter

The Vszerda CD0492 converts a USB 2.0 port into a standard RS-232 DB9 connection. It uses an FTDI chipset to appear as a native COM port on Windows, Linux, macOS, OpenBSD and FreeBSD systems. The adapter draws power directly from the USB port and requires no external supply. Gold-plated contacts provide reliable signal integrity for industrial and legacy equipment.

Replaces legacy serial ports

Modern laptops and desktops rarely include native RS-232 ports, so this adapter restores compatibility with existing serial devices. The jump is worthwhile when software expects a physical COM port and cannot address USB-native peripherals. It supports full modem control signals including RTS, CTS, DSR, DTR, DCD and RI for applications that depend on hardware flow control. The 24.0 in cable length suits bench and rack mounting scenarios.

Suits industrial and retail integrators

Technicians maintaining CNC machines, PLC controllers, POS terminals, barcode scanners or tax printers will find the broad OS support and FTDI reliability valuable. Buyers who need more than one serial channel should look at multi-port alternatives because this unit provides a single DB9 interface. Users requiring galvanic isolation or higher baud rates than standard RS-232 allows must seek specialised converters not covered by this model.
