CH384L 384 PCI Express 4S DB9 RS232 4-Port Serial Controller Card (PCIe COM Adapter)

Expand a PC with four RS232 serial ports using this CH384L-based PCI Express controller card (model 384). The 4S design provides four DB9 connectors delivering RS-232 interfaces, converting standard RS-232 signals to a PCIe COM adapter for installation in an available PCI Express slot. Ideal for adding four independent RS-232 COM ports via DB9 to systems that require legacy serial connectivity.
