  • Adds two RS-232 serial ports via PCIe x1 slot
  • Low-profile PCB fits compact chassis builds
  • WCH382L chipset provides stable serial communication
  • Data rates up to 115200 bps per port
  • Windows 2000 through 10 driver support included

Dual RS-232 expansion for legacy devices

The EN-Labs PCIE22DB9V2 adds two standard DB9 serial ports through a single-lane PCI-Express 1.0a slot. It is built for technicians and integrators who still operate industrial equipment, point-of-sale hardware or older networking gear that requires a native COM interface.

Verify Windows OS and an open x1 slot

The card relies on the WCH382L chipset and the supplier states it is not compatible with Linux systems. Confirm your motherboard has a free PCIe x1 connector and that you are running Windows 2000 through Windows 10 before ordering.

Low-profile PCB draws minimal power

The compact board fits small chassis without blocking adjacent slots and uses PCIe power management to keep consumption low. Data rates reach 115200 bps per port with automatic IRQ and I/O address assignment, so normal operation stays cool and quiet.

Perguntas sobre este artigo

Does the EN-Labs PCIE22DB9V2 ship with the full-profile bracket already attached or must I fit it myself?

The card includes a full-profile bracket for mounting; installation is required to secure it in the chassis.

Should I choose the PCIE22DB9V2 or a single-port alternative for connecting two legacy serial devices?

This model provides two RS-232 DB9 COM ports, so one card handles both devices without adding a second card.

What does the 115200 bps headline rate mean when the card is running in a Windows 10 machine?

Each serial port can transfer data at up to 115200 bps under Windows 10, with automatic IRQ and I/O address selection.
