Moxa’s 8-port RS-232 connection boxes offer a clean, structured way to connect serial devices to multiport serial boards. Each box features eight RS-232 ports and is available with DB9, 8-pin RJ45, or DB25 connectors, providing flexibility across different industrial setups.

Board-side connectivity is offered via DB62 or VHDCI 68 connectors, and each port has individual TxD and RxD LEDs for clear transmission status visibility. Selected models also include surge protection for enhanced safety in harsh environments.
