Extend the life of your expensive equipment with our DB9 Male to DB9 Female Gender Changer. Also known as a "Port Saver," this compact adapter acts as a sacrificial interface between your computer's COM port and your frequently swapped cables. Instead of wearing out the internal pins of your PLC, CNC machine, or Server, you wear out this affordable adapter!
Hardware Port Protection: Ideal for testing benches where cables are plugged and unplugged dozens of times a day.
Serial Extension: Use it as a mini-extension to give you a few extra millimeters of clearance in tight enclosures.
PLC & Industrial Programming: Protect the communication ports on high-value industrial controllers during field maintenance.
AV Control Systems: Perfect for RS232 control ports on projectors and displays located in hard-to-reach areas.
High-Quality 9-Pin Passthrough: Wired Straight-Through (1:1), ensuring that all data, ground, and handshake signals pass through perfectly.
Ultra-Slim "Mini" Profile: The compact design ensures no significant leverage or weight is added to your device's port.
Full EMI/RFI Shielding: Encased in a rugged metal shell to prevent signal interference and maintain 100% data integrity.
Secure Locking Hardware: Features threaded nuts on one side and thumbscrews on the other for a rock-solid, vibration-proof connection.
Cost-Effective Insurance: Replacing this adapter is much cheaper than repairing a broken serial port on a motherboard or industrial machine.
Zero Latency: No chips or conversion—just a high-conductivity physical bridge for instantaneous serial communication.
Industrial Grade Reliability: Rated for high mating cycles, making it suitable for professional and laboratory environments.
Connector A: DB9 Male (9 Pins)
Connector B: DB9 Female (9 Holes)
Wiring: Straight-Through (Pin 1 to Pin 1)
Does this change the signal in any way?
No. This is a passive, straight-through adapter. It simply extends the connection while maintaining the exact same pinout.
Can I use this for my VGA port?
No. Although the shell size is similar, VGA requires 15 pins (HDS15). This is strictly for 9-pin Serial/RS232 devices.
Why is it called a "Port Saver"?
In industrial and lab settings, plugging and unplugging cables can eventually break the solder joints on a device's motherboard. By keeping this adapter permanently attached, you only ever "wear out" the adapter's port, not the device itself.
