Exsys M.2 NGFF 2S Serial RS-232 Card, 2.5KV Optical Isolation (Exar Chip Set)

The EX-48200I RS-232 M.2 card is an internal expansion card with 2.5 kV optical isolation designed for compact PCs, industrial applications, motherboards, and notebooks. Instead of the mSATA interface, the M.2 bus was developed and implemented under the name Next Generation Form Factor (NGFF). The EX-48200I supports two serial RS-232 High Performance UART 16C550 outputs. It is designed to expand two additional serial ports via the M.2 (NGFF) bus. The EX-48200I comes with two flat ribbon cables with 9-pin connectors for attachment to the device's chassis.
