StarTech GC99MFRA1 Right Angle DB9 Male to DB9 Female Serial Cable Adapter Type 1

The StarTech GC99MFRA1 is a Type 1 right-angle serial cable adapter designed to facilitate connections in environments where space is limited. Featuring a DB9 male connector on one end and a DB9 female connector on the other, this adapter allows for a 90-degree bend in the cable path, preventing strain on the connector and the port. It is engineered to maintain a reliable signal path for RS-232 serial communication, ensuring consistent performance in various industrial and computing setups.

Advantages

This adapter provides a practical solution for managing cable clutter and tight installation spaces by redirecting the cable exit angle. Its robust construction ensures a secure connection between serial devices, minimizing the risk of accidental disconnection or port damage caused by sharp cable bends. The design is straightforward, allowing for quick installation without the need for additional tools, and it is built to support standard serial communication protocols effectively.

Suitable for

• Connecting serial devices in server racks with limited depth
• Industrial control systems where space behind panels is restricted
• Desktop computers or workstations positioned close to walls
• Connecting legacy serial hardware in compact enclosures

When it may not be suitable

This adapter is a Type 1 configuration, which directs the cable in a specific orientation. If your installation requires the cable to exit in the opposite direction, this adapter may not be suitable, and you should consider the alternative Type 2 version. Additionally, it is not intended for use with non-standard serial pinouts or high-speed data applications that exceed the physical limitations of the DB9 interface.

Key specifications

• Connector A: DB9 Male (Right Angle)
• Connector B: DB9 Female
• Interface: RS-232 Serial
• Orientation: Type 1
• Color: Grey

How to use

To use the adapter, simply plug the DB9 male end into the serial port of your computer or industrial device. Once securely attached, connect your existing DB9 serial cable to the female end of the adapter. Ensure that the right-angle orientation aligns with the desired cable path to avoid putting tension on the connector. The connection should be firm, and you may tighten the integrated screws to ensure a stable, vibration-resistant link.

What to consider before purchase

• Verify the required orientation of the right angle (Type 1 vs Type 2)
• Ensure the device port is a standard DB9 serial interface
• Check if there is sufficient clearance for the adapter body in your specific setup

Usage recommendations

For optimal performance, ensure that all connections are fully seated and that the screws are tightened to prevent signal interference or accidental disconnection. If the cable path still feels strained, verify that the Type 1 orientation is the correct choice for your specific port layout.
