FAQs

Will I need to plug in power to this serial card from my power supply?

Serial cards derive power from the PCI or PCI Express slot on the motherboard. When you power serial devices from the serial card ports, the power provided by the slot may not be enough to power all of the devices and you should connect additional sources of power from the power supply. When you troubleshoot issues, you should connect an additional source of power. Some signs that you are experiencing power-related issues include certain devices not working correctly, not all of the devices working at the same time, and certain devices not working at all.

PCI ExpressCards RS 232

PCI Express (PCIe) is a serial I/O technology that has been designed to deliver significantly more data than the existing PCI standard with a transfer rate of 2.5Gb/s in each direction per lane. PCIe is expected to replace PCI on all new personal computers to the end of this year. Initially, personal computers will have both PCI and PCIe slots available. Drivers for all popular operating systems, including Windows 7.
