SKU CH-B9SR-5DDJQ

Adds four RS232 DB9 serial ports via a PCIe slot using the 99100 chipset

  • Adds four serial ports via PCIe with 99100 chipset
  • Connects legacy RS-232 DB9 devices to modern systems
  • Provides four independent COM interfaces for multi-device setups
  • Uses 99100 chipset for reliable serial expansion

PCIe serial adapter with four DB9 ports

The LORDWORLD 99100 chipset card adds four RS232 DB9 COM ports through a single PCIe slot. It suits industrial automation, point-of-sale systems and legacy equipment that still rely on serial communication. The TXB077 model provides a straightforward expansion for modern motherboards lacking native COM headers.

Limited to PCIe slot availability

Installation requires a free PCIe slot and the operating system must support the 99100 driver. The adapter cannot serve devices that need USB, parallel or other interfaces, and it does not convert signal levels beyond standard RS232 voltage ranges. Buyers who need more than four ports or a different bus type should look elsewhere.
