ICP Australia is proud to introduce ICP DAS’s PCIe-S142 series card, which provides 2 RS-422/RS-485 serial ports. Uart Bridge provides automatic data direction control for RS-485 signals. Each port can be configured as either RS-485 for half-duplex or RS-422 for full-duplex communication. It supports speed up to 921600 bps and supports full-duplex communication.

The data lines of each serial port on i version PCIe-S cards come with a photocouplers design. The onboard 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 cut 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 onboard ESD protection component (for i version) diverts the potentially damaging charge away from sensitive circuits to protect the computer and equipment from the sudden and momentary electric current. Drivers provided for a broad selection of operating systems, including 32/64-bit Windows XP/2003/2008/7/8/10 and Linux Kernel 2.4X/2.6X ~ 4.15.
