INTRODUCTION
This Transceiver is designed for high-quality, IP routable, AV extension with
minimum latency. Every Transceiver is capable of simultaneous bidirectional AV
extension, enhancing the flexibility of any installation. By using a
sophisticated ultra-light compression scheme (lossless for most content) it’s
a great solution for extending 4K audio/video streams (HDMI or DisplayPort)
and data. Advanced HDMI content such as HDR (High Dynamic Range), 10-bit
colour and multi-channel HD Bitstream audio can be transmitted in pass-through
mode. The use of high quality 10 Gigabit Ethernet ports and Cat.6A or better
cable allows for point-to-point transmission distances up to 100m. Multiple
control and data signals may also be transmitted along with the audio and
video, including IR, RS-232, USB (HID only), and Ethernet.
The built-in EDID and HDCP management functionality enables the unit to fit
into every situation. Basic configuration of the unit can be achieved via
front panel buttons with an OSD (On-Screen Display).

OPERATION CONTROLS AND FUNCTIONS
6.1 Front Panel
-
POWER LED: This LED will illuminate to indicate the unit is on and receiving power.
-
SOURCE T LED: The illumination of this LED indicates which AV input is currently selected to be the source transmitted as an AV over IP stream. Green indicates the local HDMI input, amber indicates the local DisplayPort input, off indicates the incoming AVoIP stream.
-
SOURCE R LED: The illumination of this LED indicates which AV input is currently selected as the source to be output over the local HDMI output. Green indicates the local HDMI input, amber indicates the local DisplayPort input, off indicates the incoming AVoIP stream.
-
HID USB (Type-A) Ports: Connect directly to standard USB human interface devices such as a mouse or keyboard to extend their USB functionality to the currently active/routed transceiver with an active host port.
-
STATUS LED BLOCK:
• GbE LED: This LED will illuminate and blink to indicate a live and active connection on the local gigabit Ethernet port.
• VIDEO LED: This LED indicates video streaming activity over the CAT6A/7 port. It will illuminate green when a video signal is being transmitted and amber when a video signal is being received.
When bi-directional video streaming is active, both colours will illuminate. When no video is active the LED will remain off, even if the streaming connection is valid.
• LINK LED: These LEDs will illuminate and blink to indicate data transmission and reception activity across the CAT6A/7 streaming connection.
• USB LED: This LED will illuminate when the unit’s USB ports have successfully paired with the USB ports on another unit. This LED will blink if the unit’s USB ports are not currently paired and in stand-by mode. -
MENU Button: Press to enter the OSD menu, or to back out from menu items.
Note: The OSD menu will be visible on the HDMI output of both connected transceivers so it is recommended to adjust the OSD position on one unit to avoid the menus overlapping. -
(MINUS) Button: Press to move up or adjust selections within OSD menus. When not in a menu, press to manually switch between “T” source inputs.
-
(PLUS) Button: Press to move up or adjust selections within OSD menus. When not in a menu, press to manually switch between “R” source inputs.
-
ENTER/INFO Button: When inside an OSD menu, press to confirm a selection or to go deeper into a menu item. When not in a menu, press to activate the Information OSD.

6.6 Basic AV Extension
6.6.1 Point-to-Point (One Way)
The most basic extension configuration available is a point-topoint system
with a single transceiver unit acting as a transmitter connected directly to a
single transceiver unit acting as a receiver. In this configuration the
HDMI/DP input on the transmitter side is transmitted to the connected receiver
side without modification to the audio or video format. The analogue stereo
audio input on the transmitter transfers audio directly to the analogue stereo
audio output on the receiver. The LAN, RS-232 and IR ports form direct
connections between transmitter and receiver as well. This configuration is
ideal for basic video extension as well as remote KVM applications.
Note: This configuration does not use or require an external control
center such as the IP Master Controller to function. No audio
insertion/extraction is performed in this configuration.
6.6.2 Point-to-Point (Bi-directional)
Another basic extension configuration is a bi-directional point-to-point
system with the transceiver units at each end acting as both transmitter and
receiver. In this configuration the HDMI/DP input on each side is transmitted
to the opposite end of the connection for output without modification to the
audio or video format. The analogue audio, LAN, RS-232 and IR ports form
direct connections between both ends as well.
This configuration is ideal for long distance, secure, fixed-point video
conferencing
Note: This configuration does not use or require an external control center such as the IP Master Controller to function. No audio insertion/extraction is performed in this configuration.
