4. Functionality
The Moxa Opt8B functions as a passive breakout box that distributes serial communication signals from a single high-density DB62 connector (on the host side) into eight individual RS-232 (DTE) DB25 male connectors. Each port corresponds to one serial channel from the connected Moxa C168 or C218 multiport serial board.
How It Works:
- The DB62 connector on the Opt8B connects to the DB62 port on the Moxa C168 or C218 board using the included 1.5 m cable.
- The internal wiring maps each of the eight serial channels from the board to the corresponding DB25 male connectors on the box.
- Each DB25 port operates as a DTE (Data Terminal Equipment) interface, ready to connect directly to DCE (Data Communication Equipment) devices such as modems, serial printers, barcode scanners, or other RS-232 peripherals.
- The box requires no external power or configuration; it simply routes signals between the board and connected devices.
Use Cases and Applications:
- Industrial automation systems requiring multiple serial device connections
- Data acquisition and control systems
- POS (Point-of-Sale) and retail terminal networks
- Laboratory instrumentation and test setups
- Communication hubs for legacy serial equipment
- Integration of multiple RS-232 devices into a single host system
Compatibility:
- Fully compatible with Moxa C168 and C218 series multiport serial boards
- Supports standard RS-232 signaling, ensuring interoperability with a wide range of serial devices and cables
