4. Functionality
The Moxa Opt8D functions as a breakout cable that converts a single high-density DB62 connector into eight standard RS-232 (DTE) DB9 male connectors. It is designed to interface directly with Moxa’s C168 and C218 multiport serial boards, which provide multiple serial communication channels through a single high-density connector.
When connected, each DB9 male connector operates as an independent RS-232 DTE port, supporting standard serial communication signals such as TXD, RXD, RTS, CTS, DTR, DSR, DCD, and GND. This allows users to connect up to eight RS-232 devices—such as barcode scanners, modems, PLCs, sensors, or terminals—to a single host system equipped with a Moxa multiport serial board.
Typical Use Cases:
- Industrial automation systems requiring multiple serial device connections
