This HL340 USB to RS232 DB9 9pin serial adapter cable bridges modern USBonly computers and traditional RS232 serialport hardware. Adopting mature HL340 controller chip, it turns USB signal into standard RS232 COMport signal for stable serial communication. It works well with PDA handheld units, PLC controllers, POS machines, industrial meters, serial printers and other DB9equipped legacy devices.
Driver installation is mandatory before use; the dedicated HL340 driver enables correct COM port generation under Windows 7 32bit and 64bit environments. Wellmade DB9 connector ensures tight connection and reduces signal dropout during longtime debugging and data transmission.
Lightweight cable form saves workspace, convenient for field maintenance, laboratory testing and onsite device parameter setting. Please note this adapter only supports RS232 serial protocol. Verify your device interface and operating system before purchase. It is a costeffective solution to reuse older serialport peripherals on computers without native DB9 COM ports.
