Oultech Co., Ltd. has released three expansion card products that add serial ports. They are all immediately available for an estimated store price of around 39 dollars for PCIe 2.0 x 1 connection / 4-port “OWL-PCEX2RS232X4”, around 34 dollars for PCIe 2.0 x1 connection / 2 port “OWL-PCEX2RS232X2”, PCIe 1.1 x1 Connection / 2 port OWL-PCEX1RS232X2 is expected to be around 27 dollars.
All three Oultech PCIe 2.0 / 1.1 expansion cards are expansion cards that can add a D-Sub 9-pin serial port. Older PC hardware will definitely become useable with this accessory.
The maximum baud rate is 250Kbps, 230.Kbps, and 250Kbps in order, and Oultech PCIe 2.0 / 1.1 expansion card corresponds to Windows XP or later. Occupied slots are 2 for the 4-port model and 1 for the 2-port model.
Main body size / weight of Oultech PCIe 2.0 / 1.1 expansion cards is approximately 120 × 116 × 25mm (width × depth × height) / approximately 55 grams, approximately 120 × 102.5 × 25mm (same) / approximately 56 grams, approximately 120 × 80 × 25mm (same) / approximately 42 grams. A driver installation CD is included in package as well.
In most cases, it is going to be plug and play since most modern operating systems support PCIe expansion slot natively.
