Description
The Sunix 6456PH is a high performance PCI Express serial expansion card developed for business, industrial and commercial environments where dependable RS232 communication remains essential. Using a PCI Express x1 interface, the card adds four independent high speed serial ports while maintaining compatibility with modern desktop systems.
Built around the SUN2410 chipset with a 16C950 UART, the card supports communication speeds of up to 921.6 Kbps and includes large 128 byte hardware FIFO and 128 KB software FIFO buffers for stable data transmission during continuous operation.
A key advantage of the Sunix 6456PH is the individually selectable 5V, 12V or RI output available on every serial port. This allows supported serial peripherals to receive power directly through the serial connection without requiring a separate AC adapter. Integrated 1.1 Amp PTC protection helps safeguard connected equipment while advanced ESD protection improves reliability in electrically demanding environments.
The included standard and low-profile brackets allow installation into both full height and compact computer chassis, making the card suitable for office systems, industrial PCs, embedded computers and rack mounted servers.

Optional 5V / 12V / Signal Output over COM
For SUNIX PoweredIO Serial card, user can select +5VDC and +12VDC power output over both COM 1st or 9th pins. In addition, this board also keeps the original RS-232 signal for traditional application using. In order to make sure the power stable and convenient, the DC power sources from the system power supply over standard Serial-ATA power socket. SUNIX PoweredIO Serial card is designed for users who want to connect serial peripherals without using extra power adaptor.
Reliable Circuit Protection
Each RS-232 port is protected with a 1.1 Amp PTC (Positive Temperature Coefficient) resettable fuse. The PTC may temporarily allow more that 1.1 Amp to be drained. Typically, a PTC will shut off after approximately 15 seconds drawing more than 1.9 Amp. The PTC will turn off the power for each individual port if an unusual overload is sustained. Besides in order to satisfy kinds of serial device power requirements, each RS-232 port can support 1100mA output in the PCB circuit design.
