Product information

The EX-48240 RS-232/422/485 M.2 card is an internal expansion card for compact PCs, industrial applications, mainboards and notebooks. Instead of the mSATA interface, the M.2 bus was developed and used under the name Next Generation Form Factor (NGFF). The EX-48240 supports four serial RS-232, 422 or 485 high performance UART 16C550 outputs. It has been developed to extend four more serial ports via the M.2 (NGFF) bus. The EX-48240 comes with two ribbon cables with 9 pin connectors for mounting on the housing of the device.
