The SIIG 04-1284B is an Ethernet-based system designed to extend Full HD HDMI signals over IP. It supports point-to-point, multicast, and screen wall configurations. The system requires a 10/100 BASE-T switch hub and CAT-5 cabling. Configuration is primarily managed via the IPTV_Control_Center.exe PC tool.
Device Description
The system consists of a Transmitter (TX) and a Receiver (RX). Both units feature a 2.0mm power jack, a LAN port (RJ-45), a 3.5mm IR jack, a DB-9 RS-232 connector, a 6-bit DIP switch for channel selection, and a Reset button. The Transmitter includes an additional HDMI loop-through output.
Installation
Follow these steps to set up the system:



- Set the same Group ID on both the transmitter and receiver using the 6-bit DIP switches.
- Connect HDMI cables from the video source to the transmitter input, and from the receiver output to the display.
- Connect the CAT-5 cable between the transmitter, the Ethernet switch, and the receiver.
- Connect the DC5V power adapters to both the transmitter and receiver.
- Power on the source device.
- Connect the IR emitter cable to the transmitter and the IR receiver cable to the receiver if remote control of the source is required.
Configuration
The system is managed using the IPTV_Control_Center.exe software. Ensure your PC is connected to the same network switch. If the LAN lacks a DHCP server, the extender defaults to a 169.254.xxx.xxx IP address; you must set your PC to a static IP in the same range (e.g., 169.254.11.11) to access the device. Disable system firewalls or antivirus software when running the tool. Use the 'Device Scan' page to find connected units, then use the 'TX Setup' and 'RX Setup' pages to adjust IP settings, video bitrates, and group IDs.


Web User Interface
Advanced configuration can be performed via a web browser. The default login credentials are User Name: admin and Password: 123456. Through the web interface, you can update firmware, manage multicast settings, and perform device reboots or factory resets.

Specifications
The system supports H.264 video compression and stereo 192Kbps audio. It handles resolutions up to 1080p at 60/50Hz. Operating temperature is 0 to 55 degrees Celsius. The units feature ESD protection (air gap 8KV, contact 4KV) and weigh 290g each.
