4. Setup and Installation
The kit provides two primary application scenarios for easy connection setup:
Application A: Two Devices Share a Single Cat5e/6 Cable
This setup is ideal for connecting two standard Ethernet devices (e.g., a computer and a printer) to a single router port using one long Cat5e/6 cable.
- Connect one male RJ45 end of the first splitter unit to a LAN port on your router.
- Connect the single female RJ45 port of the first splitter unit to one end of your Cat5e/6 cable.
- At the remote end, connect the other end of the Cat5e/6 cable to the single female RJ45 port of the second splitter unit.
- Connect your first device (e.g., Computer) to one of the male RJ45 ends of the second splitter unit.
- Connect your second device (e.g., Printer) to the other male RJ45 end of the second splitter unit.
- Ensure all connections are secure. The splitter uses all 4 pairs of wires for data transmission.
Application B: 2-in-1 (Two Cameras Over One Cable) Cat5e/6 POE Power/Data Transmission
This setup is specifically designed for surveillance systems, allowing two IP cameras (with or without PoE) to transmit data and power (if PoE) over a single Cat5e/6 cable from a PoE switch or NVR.
- Connect the two male RJ45 ends of the first splitter unit to two separate PoE ports on your PoE switch or NVR.
- Connect the single female RJ45 port of the first splitter unit to one end of your Cat5e/6 cable.
- At the remote camera location, connect the other end of the Cat5e/6 cable to the single female RJ45 port of the second splitter unit.
- Connect your first IP camera to one of the male RJ45 ends of the second splitter unit.
- Connect your second IP camera to the other male RJ45 end of the second splitter unit.
- If cameras are not PoE, ensure they have separate power adapters connected. The splitter facilitates data and power transmission over the single cable.

5. Operation
Once properly connected, the TNP RJ45 Ethernet Cable Combiner/Splitter Kit operates by effectively splitting or combining Ethernet signals over a single cable run. It maintains a stable network connection without compromising speed or signal quality for 10/100 Mbps networks.
- Data Transmission: The adapter facilitates data transfer for two separate devices over one physical Ethernet cable.
- PoE Functionality: In PoE setups, it allows power and data to be transmitted to two PoE-enabled devices (e.g., IP cameras) using a single cable from a PoE switch.
- Signal Integrity: Designed to maintain signal integrity over extended distances, as detailed in the specifications.

6. Care and Maintenance
To ensure the longevity and optimal performance of your TNP RJ45 Ethernet Cable Combiner/Splitter Kit, follow these simple care and maintenance guidelines:
- Keep Dry: Avoid exposing the units to moisture or extreme humidity.
- Clean Gently: If cleaning is necessary, use a soft, dry cloth. Do not use liquid cleaners or solvents.
- Handle with Care: Avoid bending or twisting the cables excessively, especially near the connectors, to prevent internal wire damage.
- Secure Connections: Ensure all RJ45 connectors are fully seated and latched into their respective ports to prevent intermittent connections.
- Environmental Protection: While the units have surge protection, it is advisable to use them in environments with stable power supply and away from direct lightning strikes.
7. Troubleshooting
If you encounter issues with your TNP RJ45 Ethernet Cable Combiner/Splitter Kit, refer to the following common troubleshooting steps:
