4. Functionality
The JS Automation SM23410 functions as a passive extension interface that connects internal serial communication headers (COM2 and COM3) on a motherboard or controller board to external DB9 male connectors accessible from the rear panel of a computer or enclosure.
How It Works:
Each 10-pin IDC connector on the flat ribbon cable plugs directly into a corresponding COM header on the motherboard. The bracket’s DB9 male connectors are wired according to the standard RS-232 pinout, allowing external serial devices to communicate with the system through these ports. The bracket does not perform any signal conversion; it simply routes the electrical signals from the internal header to the external connectors.
Use Cases and Applications:
- Industrial PCs requiring external serial connectivity for legacy equipment
- Embedded systems and automation controllers with internal COM headers
- Laboratory instrumentation and test setups using RS-232 communication
- Serial device interfacing for modems, barcode readers, and data loggers
- Integration in control panels or enclosures where external serial access is needed
- Maintenance and diagnostic interfaces for embedded boards
Compatibility:
- Compatible with standard PC motherboards supporting COM2 and COM3 headers
- Works with RS-232 compliant devices and peripherals
- Suitable for Windows, Linux, and embedded operating systems that support onboard serial ports
