Bo mạch truyền thông cổng nối tiếp PCI Express 2 cổng cách ly RS-232 ICP DAS PCIe-S112i CR

The PCIe-S112 series card provides 2 RS-232 serial ports. It is equipped with a 128-byte hardware FIFO for each port, supports for speed up to 921600 bps and supports full-duplex communication.

The driver provides a maximum of 256 KB software FIFO for each COM port under Windows. It’s practical for large file transmission.

The data lines of each serial ports on i version PCIe cards come with photocouplers design. The on-board photo couplers use a short optical transmission path to transfer a signal between elements of a circuit, and keep the data lines electrically isolated. It can help cutting down on ground loops, common mode voltages and block voltage spikes, provide electrical isolation, and offer significant protection from serious over-voltage conditions in one circuit affecting the other.

In harsh industrial environments, the on-board ESD protection component (for i version) diverts the potentially damaging charge away from sensitive circuit to protects the computer and equipment from the sudden and momentary electric current.

The serial communication card are designed for use with intelligent devices like bar code reader, serial printers, intelligent sensors, instrumentation equipment, computers and almost any device with an RS-232 port.
