2. Setup and Installation

The Monoprice DB9 Male to Female Mini Port Saver is designed for straightforward installation.

1. Port Protection: To protect an equipment port, connect the male end of the port saver to the female port on your device (e.g., computer, serial device). Then, connect your existing DB9 cable to the female end of the port saver. Secure the connection using the integrated screw and nut connectors to prevent accidental disconnections.
2. In-Line Coupling: To extend a DB9 cable, connect the male end of the port saver to a female DB9 cable, and then connect another male DB9 cable to the female end of the port saver. Ensure all connections are firm and secured with the screws/nuts.

3. Operation

Once connected, the port saver operates passively, providing a direct pass-through connection for all 9 pins of the DB9 interface. It does not require external power or software. Its primary function is to absorb the physical stress of repeated connections, thereby preserving the integrity of your equipment's built-in ports.

4. Maintenance

The Monoprice DB9 Male to Female Mini Port Saver requires minimal maintenance. Keep the connectors clean and free of dust or debris. Avoid exposing the adapter to extreme temperatures or moisture. Do not apply excessive force when connecting or disconnecting cables, as this can damage the pins or the adapter itself.

5. Troubleshooting

Incorrect Labeling as 'Gender Changer'

Please note that while some units of this adapter may be incorrectly labeled as a 'Gender Changer', it is functionally a port saver and an in-line coupler for DE-9 (DB-9) connections. It maintains the male-to-female pin configuration, allowing for direct pass-through of signals without altering the gender of the connection.

No Signal / Intermittent Connection

• Ensure all connections (to the equipment, the port saver, and the connecting cable) are fully seated and secured with the screws/nuts.
• Inspect the pins on both the port saver and your cables for any bends or damage.
• Test the connection without the port saver to determine if the issue lies with the cables or the equipment itself.
