NetworkAV™ H.264 HDMI Transmitter over IP with PoE & RS-232
Extend and Distribute 1080p HDMI over Any IP Network up to 394 ft with Dual PoE Power
The EXT-AVIPH264TX eliminates dedicated AV cabling for multi-display installations by encoding and transmitting full HD 1080p HDMI signals over a standard Ethernet network up to 394 ft (120m) using H.264 compression over TCP/IP. A single CAT5e/6 run carries video, audio, IR control, and RS-232 — with PoE eliminating the need for a local power outlet at the transmitter.
Designed for integrators deploying digital signage, corporate AV, and multi-zone display systems, the EXT-AVIPH264TX supports point-to-point, one-to-many, and many-to-many topologies over a managed Gigabit switch. Group ID selection via remote controller or web browser allows source-switching without recabling, and the HDMI loopthrough output keeps a local display active at the source.
- Encodes and transmits pure 1080p HDMI signals up to 394 ft (120m) over a single CAT5e/6 cable
- H.264 compression over TCP/IP — 15 Mbps streaming bit rate, LPCM audio at 48kHz
- Dual power input: 802.3af PoE compliant + DC 5V (no power adapter required when using PoE switch)
- Supports point-to-point, one-to-many, and many-to-many configurations — up to 64 TX / 255 RX nodes
- Group ID source switching (00–63) via IR remote controller or web browser
- Bidirectional RS-232 pass-through up to 115,200 baud — 8 baud rate presets
- Wideband IR pass-through 38–56kHz for remote source control at the display location
- HDMI loopthrough output for simultaneous local display at the transmitter
