The CyberSerial 4S from SIIG is a PCI expansion card that adds four serial ports to your PC. The card is an ideal solution for connecting legacy serial devices, such as scanners and deck control devices, to modern computers that don't have a built-in serial port.
5V/12V Power Output
The card can function as a standard RS-232 port, or it can be configured via jumpers to provide devices with 5V or 12V or power. This allows it to be used to connect devices that require power, such as handheld scanners and POS displays.
