Industrial 2 ports RS-422/485 M.2 (2280 Type, Key B+M) with Surge PCI-Express Serial Card

SUNIX IPC-M2202S, Industrial 2 ports RS-422/485 with Surge PCI-Express Serial M.2 Card, allows users to expand two RS-422/485 ports on M.2 with Key-M or Key-B based PC-based system. The RS-422/458 COM ports can be attached to a housing or slot bracket. Each serial port achieves data rates up to 921.6 Kbps and utilizes 16C950 UART with an on-chip 128-bytes hardware FIFO buffer for reliable, high-speed serial I/O. With SUNIX patented Auto-Switching RS-422/485 and RS-485 AHDC™ technology, user can easily manage different serial interfaces selection and RS-485 signal direction control. SUNIX IPC-M2202S board is provided with 2KV IEC6100-4-5 Level 3 Surge Suppressor and ±15KV IEC61000-4-2 ESD Discharge Transceiver. Besides, board supports a wide variety of operating systems, including Windows, Linux, DOS, and UNIX. It is the best serial communicating solution for industrial and harsh environment applications.
