Product ID: PEX16S550LP
This PCI Express serial card adds 16 high-speed RS232 ports to your standard or low-profile desktop or server PC. This lets you maximize the number of available DB9 RS232 ports that are available for connecting your serial-based devices and equipment, while using only a single PCI Express (PCIe) slot. It's the perfect solution for adding the serial ports you need, even if your desktop PC or server only has a limited number of PCIe expansion slots.
You can install the serial card to add 16 high-performance DB9 RS232 serial ports from a single PCIe slot. With two breakout cables of 8 ports each, the PCIe serial card maximizes the density of DB9 RS232 ports on a server or desktop computer. It's ideal for system upgrades in a wide range of applications, including manufacturing equipment, POS equipment, security devices such as surveillance cameras, and environment or building control systems.
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 PCIe serial card delivers high-performance, high-speed serial communication, with support for data transfer rates of up to 921.6 Kbps.
The serial card is easy to install and configure, and compatible with a broad range of Windows® and Linux® operating systems. The card features IRQ sharing and supports plug-and-play serial device connections, which makes it convenient and easy to connect serial devices. It includes a low-profile bracket making it compatible with both full profile and low profile PC chassis slots.
The PEX16S550LP is backed by a StarTech.com 2-year 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.

To confirm that Windows detects your expansion card, complete the following:
Your expansion card is listed according to the name of the chipset. To determine the name of the chipset of your expansion card, navigate to www.StarTech.com and look on the Technical Specifications tab for your product.
It is not required to use the power connector on the card, but certain modes will only be available while using the connector. For instance, jumpers can be placed on the card to draw 12V or 5V from the power connector to assist with power output through the DB connectors. If these modes are activated without the power connector, the card will not function correctly.
