Your Guide to Selecting a Serial RS-232 Expansion Port for PCI Express x1

Equipping yourself with the right RS-232 expansion port can give you the power to breathe new life into old printers or even enjoy playing vintage video games with your kids on CRT monitors. Some of these devices are designed to allow you to use multiple peripherals at the same time, and they are all engineered to be compatible with PCI-express power management systems. All it takes to find an expansion port that will work for your needs is a quick look through this collection.

Many manufacturers make expansion ports for these types of connectors. These serial ports are offered in a variety of styles, and each style is designed to work best for a particular application. Some of the styles offered include:

• Single RS-232 port: These expansion cards feature a single port that can connect to an RS-232 serial peripheral.
• RS-232 and DB25 card: These devices include ports for both serial devices and DB25 devices.
• Dual serial port: These ports are unique in that they have slots for multiple serial devices aligned next to each other on a small circuit board.
• Serial port splitter: This option consists of a single serial connector that branches off into many different connectors. These ports feature between two and four branches.

If you only need to connect one serial peripheral to your computer, your needs might be best met with a single serial port expansion card. If you foresee yourself needing to connect multiple serial peripherals at a time, you'd be better off with an expansion card that has more than one port.

Before making a decision, it's also important to check the power management system that your computer uses. This information is usually included in your computer's owner's manual, and it is also commonly listed on your power supply.

Each expansion port model may have a slightly different procedure, so refer to owner's instructions. The general guidelines for installing one are:

• Step 1: Turn off your computer's power supply and remove the AC power cord.
• Step 2: Open up your computer's case and locate the space allocated to expansion cards. This area is usually at the back of the computer.
• Step 3: Screw the expansion card into place. Then, connect the card directly to the power supply.
• Step 4: Boot up your computer and test the expansion port by connecting a peripheral.
