### 4. Functionality

The INJ-102GT functions as a Power Sourcing Equipment (PSE) device that injects power into Ethernet cables while maintaining full data throughput. It enables network devices that require both data and power—such as IP cameras, wireless access points, and VoIP phones—to operate without separate power supplies.

Operation Principle:
1. The injector receives data from a non-PoE switch or network device through its “Data IN” ports.
2. It combines the data signal with DC power and transmits both through the “PoE OUT” ports.
3. The connected powered device (PD) receives both power and data over a single Ethernet cable.
4. The injector’s intelligent detection circuit ensures that power is only applied when a valid IEEE 802.3af/at signature is detected, preventing accidental damage to non-PoE equipment.

Use Cases and Applications:
- Industrial automation and control systems
- IP surveillance networks
- Wireless access point installations
- VoIP telephony systems
- Transportation and outdoor networking
- Smart building and IoT infrastructure

Compatibility:
- Compatible with all IEEE 802.3af/at compliant powered devices
- Works with standard CAT5e/CAT6 Ethernet cabling up to 100 meters
