Introduction

SUNIX SER6456SHL, PCI Express serial communication board, supports +5 or +12VDC of power via COM 1st and 9th pin output. It's convenient for users connecting serial devices without addition external power supply.

SUNIX SER6456SHL meets the PCI Express Base Specification Revision 2.0, allows users to add or expand four RS-232 COM ports on PC-based system to use serial devices further. It is compatible with PCI Express x1, x2, x4, x8 and x16 lane Bus allowing it to be installed in any slim size PC-based system with low profile bracket structure. The majorities of today’s motherboards does not equipped with serial ports or only have one serial port. With SUNIX PCI Express serial board, users can add one serial port to their system, allowing them to use serial devices further. This serial board has 128-bytes onboard FIFO buffer and compatible with 16C950 UART specification. It is designed with SUNIX native PCI Express UART controller, SUN2410 and as well built with many of SUNIX advanced features and technologies, making it the best solution for commercial and industrial automation applications.

Features

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.

For example, user can select +12VDC output to invoice printer on first port, +5VDC output to barcode scanner on second port, and RI signal to modem on the third port. 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.
