Exsys 2 Port RS422, RS485 Serial Card

The Exsys M.2 card is an internal expansion card with 2.5KV Optical Isolation for compact PCs, industrial applications, mainboards and note-books. Instead of the mSATA interface, the M.2 bus was developed and used under the name Next Generation Form Factor (NGFF). It supports two serial RS-422 or 485 high performance UART 16C550 outputs. It has been developed to extend two more serial ports via the M.2 (NGFF) bus. It comes with two ribbon cables with 9 pin connectors for mounting on the housing of the device.
