1. Introduction
This manual provides instructions for the VCELINK RJ45 Shielded Ethernet Coupler, Model M236-2P-US. This device is designed to extend the length of Ethernet network cables (Cat5, Cat5e, Cat6) by connecting two RJ45 male cables. It supports Power over Ethernet (PoE) applications and ensures high-speed data transmission without signal degradation.

2. Setup
The VCELINK RJ45 Coupler features a plug-and-play design for straightforward installation.
- Identify the two RJ45 male Ethernet cables you wish to connect.
- Insert the RJ45 connector of the first Ethernet cable into one end of the VCELINK coupler until it clicks securely into place.
- Insert the RJ45 connector of the second Ethernet cable into the other end of the VCELINK coupler until it clicks securely into place.
- Ensure both connections are firm to prevent signal loss.

3. Operation
Once connected, the VCELINK RJ45 Coupler operates automatically, extending your network connection. No additional configuration is required.
- High-Speed Transmission: Supports up to 1Gbps (1000Mbps) transmission speed, compliant with TIA/EIA 568-C.2 standard.
- Backward Compatibility: Fully compatible with Cat5e and Cat5 network cables.
- PoE Support: Designed to work with Power over Ethernet (PoE) devices without performance degradation.
- Signal Integrity: Engineered to extend cable length without affecting network speed or signal quality.

4. Maintenance
The VCELINK RJ45 Coupler is designed for durability and requires minimal maintenance.
- Cleaning: If necessary, gently wipe the exterior of the coupler with a dry, soft cloth. Avoid using liquid cleaners directly on the ports.
- Storage: Store the coupler in a dry environment, away from extreme temperatures and direct sunlight, when not in use.
- Durability: The aluminum alloy housing provides wear-resistant and shockproof protection. Gold-plated contacts resist corrosion for long-term stable performance.

5. Troubleshooting
If you experience issues with your network connection after using the coupler, consider the following:
- No Network Connection:
- Ensure both RJ45 cables are fully inserted into the coupler and click into place.
- Verify that the Ethernet cables themselves are functional by testing them individually or with a different connection.
- Check the network status indicators on your connected devices (e.g., router, computer).
- Slow Network Speed:
- While the coupler is designed for lossless extension, ensure all cables used are of appropriate category (Cat5e or Cat6 recommended for 1Gbps).
- Test the network speed without the coupler to isolate the issue.
- Intermittent Connection:
- Re-seat both cables in the coupler to ensure a secure connection.
- Inspect the RJ45 connectors on your cables and the coupler ports for any visible damage or bent pins.
