### 4. Functionality

The INJ-102GT++-24V functions as a Power over Ethernet injector, combining power and data onto a single Ethernet cable to supply connected devices. It receives data from a non-PoE network switch or router via its “Data IN” ports and injects DC power into the Ethernet line through its “PoE OUT” ports.

Operation Principle:
1. The injector detects whether the connected device supports IEEE 802.3af/at PoE standards.
2. If a valid PoE signature is detected, the injector enables power output on the corresponding port.
3. Power and data are transmitted simultaneously over the same cable up to 100 meters, in compliance with Ethernet standards.
4. The internal boosting circuit ensures stable 50 VDC output even when the input voltage is as low as 24 VDC.

Use Cases and Applications:
- Industrial automation systems
- IP surveillance networks (PTZ cameras, IP cameras)
- Wireless access points and bridges
- VoIP phones and network terminals
- Remote sensors and controllers in SCADA systems
- Transportation and outdoor networking equipment

Compatibility:
- Compatible with all IEEE 802.3af/at-compliant powered devices
- Supports LT PoE++™ PDs for extended power delivery (>30 W per port)
- Works with standard CAT5e/CAT6 Ethernet cabling up to 100 meters
