4. Installation Instructions
Follow these steps to properly terminate your trueCABLE Shielded Cat6A Keystone Jack:
- Prepare the Cable: Strip approximately 1.5 to 2 inches of the cable jacket. Untwist the wire pairs and straighten the individual conductors. Ensure the cable's foil shield (if present) is folded back or trimmed appropriately, leaving enough for grounding.
- Insert Wires into Termination Cap: Refer to the T568A or T568B wiring diagram printed on the dual-level termination cap. Carefully insert each colored wire into its corresponding slot. The dual-level design helps keep conductor pairs separate and organized.
- Seat the Termination Cap: Once all wires are correctly placed in the cap, trim any excess wire extending beyond the cap.
- Close the Keystone Jack: Open the metal housing of the keystone jack. Insert the terminated cap into the jack's IDC (Insulation Displacement Connector) block. Close the metal housing firmly until it snaps shut. This action simultaneously seats the wires and provides strain relief. The self-adjusting spring ensures proper shield contact.
- Secure with Cable Tie: Use the provided nylon cable tie to further secure the cable to the keystone jack, preventing accidental dislodgement or strain on the termination.
- Test the Connection: After termination, it is recommended to test the connection using an RJ45 cable tester to ensure proper continuity and wiring.

5. Operating Instructions
Once properly installed and terminated, the trueCABLE Shielded Cat6A Keystone Jack functions as a passive network connector. To operate:
- Insert a standard RJ45 Ethernet patch cable into the front port of the keystone jack.
- Ensure the RJ45 plug clicks securely into place.
- The keystone jack will then provide a stable and high-speed connection for your network devices.
6. Maintenance
The trueCABLE Shielded Cat6A Keystone Jack requires minimal maintenance. To ensure optimal performance and longevity:
- Regular Inspection: Periodically inspect the keystone jack and connected cables for any signs of physical damage, such as bent pins, cracked housing, or frayed cables.
- Cleaning: If necessary, gently clean the RJ45 port with a lint-free cloth or compressed air to remove dust or debris. Avoid using liquid cleaners directly on the contacts.
- Secure Connections: Ensure all connected patch cables are securely seated in the keystone jack.
7. Troubleshooting
If you experience issues with your network connection, consider the following troubleshooting steps:
- No Network Connection:
- Verify that the Ethernet cable is properly terminated into the keystone jack according to the T568A or T568B standard.
- Ensure the keystone jack's housing is fully closed and the wires are securely seated in the IDC terminals.
- Check the integrity of the patch cable connecting to the keystone jack and the device.
- Use an RJ45 cable tester to confirm continuity and correct wiring of the terminated cable.
- Slow Network Speed:
- Ensure all components in your network chain (cables, switches, routers) are rated for Cat6A or higher speeds.
- Inspect for any damage to the keystone jack or cables that might be causing signal degradation.
- Confirm that the cable length does not exceed the recommended maximum for Cat6A (328 feet for 10 Gigabit).
- Intermittent Connection:
- Re-seat the patch cable in the keystone jack.
- Check for loose connections within the keystone jack's termination. Re-terminate if necessary.
- Ensure proper grounding for shielded installations to prevent interference.
