High Density Design: 8 switchable RS-232/422/485 ports and 4 dedicated RS-232 ports on one small, PC/104 footprint.

Protection: Ports are individually electrically isolated at 1.0 kV AC peak to peak from the main board and from each other.

Speed: Supports data communications speeds up to 460.8 Kbps (RS-422/485) and 115.2 Kbps (RS-232).

Performance: 16C2550 dual UARTs control each port, providing 128 bytes of TxD/RxD FIFO buffers.

Adaptability: Support for all three RS-485 modes: Full Duplex, Half Duplex and Multi-drop.

Support: Lifetime warranty and free technical support.
