Connector Design

The BDD DE9S combines a female DB9 serial interface with a screw-terminal breakout arrangement. Instead of soldering wires directly to the connector contacts, users can insert individual conductors into the screw terminals and tighten the screws to secure the connection.

This design makes the connector convenient for custom wiring, repairs, and installations where quick access to the individual signal connections is required.

The included 10-pin terminal block provides the connection points for the connector assembly. The exact terminal-to-pin layout and use of the additional terminal should be confirmed against the supplied wiring diagram or product documentation.

RS232 and Serial Applications

The DB9 female connector is suitable for compatible RS232 serial communication systems and other equipment that uses a matching 9-pin female D-Sub interface.

Potential applications include:

• RS232 serial communication wiring.
• Industrial control equipment.
• Computer and peripheral serial interfaces.
• Electronic test and measurement equipment.
• Custom serial cable assemblies.
• Electronics prototyping.
• Equipment maintenance and repair.
• Automation and control projects.

Compatibility note: A DB9 connector's physical shape does not guarantee compatibility with every DB9 application. Confirm the required pinout, electrical interface, and wiring configuration before connecting equipment.

Installation and Wiring

The BDD DE9S is designed to simplify field termination and custom cable assembly.

1. Prepare the cable by stripping the insulation from the individual conductors.
2. Identify the required wires and corresponding pin positions.
3. Insert each conductor into the appropriate screw terminal.
4. Tighten the terminal screws to secure the wires.
5. Check the wiring against the required pinout.
6. Close the protective case and secure the connector using the supplied thumb screws where applicable.
7. Test the completed connection before placing the equipment into service.

Always verify the pinout and ensure that connected equipment is powered off during installation.

• Thumb Screws.

Important Information

• This product is a connector and cable termination accessory, not a complete serial communication device.
• Confirm the required pinout and electrical compatibility before use.
• The supplied information does not specify cable gauge, terminal pitch, operating temperature, or connector dimensions.
• Ensure that all screw terminals are securely tightened before operation.
• Actual compatibility depends on the connected equipment's interface and wiring requirements.
