Product ID: PEX2S1050
This PCI Express serial card adds two high-performance RS232 serial ports to your desktop computer or server, for connecting your serial-based devices and equipment.
The PCIe serial card can be installed into an available PCI Express slot, to provide two high-performance 16C1050 RS232 serial UART channels/ports. It offers a convenient solution for connecting modern or legacy equipment to newer computer systems that don't have RS232 ports. The serial card is compliant with PCI Express 1.0a specification, and it's compatible with 1x, 2x, 4x, 8x and 16x PCI Express slots.
The 2-port PCIe serial card is ideal for system upgrades in a wide range of applications including manufacturing equipment, POS equipment, security devices such as surveillance cameras, card readers or access panels, and environment or building control systems.
The PCIe serial card delivers high-performance serial communication, with support for data transfer rates of up to 460Kbps. The serial card provides CPU load decrease which helps ensure optimal system performance and prevent errors such as overruns by preserving resources. In addition, the dual-channel UART ensures smooth performance, even while both ports are in use.
The serial card is easy to install and configure, with support for a broad range of Windows® operating systems. Plus, the card features IRQ sharing and supports plug-and-play serial device connections, guaranteeing convenient, hassle-free installation. It comes with a standard-profile bracket installed, and also includes an optional low-profile bracket.
The PEX2S1050 is backed by a StarTech.com lifetime warranty and free lifetime technical support.

Older applications that use serial communication often use legacy hardware addresses that do not work with PCI, PCIe, or USB to Serial products. We recommend contacting the software provider/support team to check if this is the case.
When you troubleshoot issues with a serial device, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
Serial cables
Serial ports
Serial devices
To test your setup components, try the following:
Use the serial cable, serial port, and serial device in another setup to see if the problem is with the components or the setup.
Use a different serial cable, serial port, and serial device in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
Test each cable individually.
Use short cables when you are testing.
When you test the serial ports and serial device, it is recommended that you do the following:
Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager. Check to see if your device is listed under Ports (COM & LPT).
Make sure that the COM port number is the correct number for the serial device and that the software being used to connect the computer to the serial device uses the correct COM port number.
If the device is listed with an error, follow the instructions on the website to reinstall the drivers.
Note: Some serial devices work only if the COM port number is between a certain range. For example, COM1 to COM4.
Perform a serial loopback test. See this FAQ on how to perform a RS-232 serial loopback test: http://www.startech.com/faq/serial_loopback_test_rs232_windows
To check whether or not an RS-232 serial port is working, perform an RS-232 loopback test by doing the following:
Note: To open a telnet session on the COM port, you need a telnet client like PuTTY or Hyper Terminal. Windows XP comes with Hyper Terminal.
If the loopback test fails, make sure that the serial cable or gender changer that you are using works and that the adapter is in the correct port.
You can check multiple ports at the same time by opening multiple sessions, putting the loopback adapter on one port, and trying to type into each session. When you can see what you are typing, you know that the COM port is working and you can see which port number the physical serial port is. Close the window for the port that you just tested to speed up the testing of the remaining serial ports.
