Thank you for purchasing this PRODUCT.
This PRODUCT is designed with the professional AV installers in mind. The many extensive
features assist with system integration, validation and maintenance.
Installation precautions
This product has special circuitry to protect it against moderate surges and static discharges.
However, to ensure reliable operation and long service life, it is important to take the
necessary precautions against any spikes, surges and static discharges.
Place the units away from heat sources and allow adequate ventilation.
Shielded cable and in particular cat6, cat6a or cat7 is highly recommended. As much as
possible signal cables should be routed away from any noisy sources and should avoid long
runs in close proximity to AC mains cables.

Connecting to the Matrix
1. Connect the HDMI sources to the HDMI inputs
2. Connect the Xcalibur 11 receivers to the HX outputs
3. Connect HDMI display devices to the Xcalibur 11 receivers
4. If required, connect local HDMI displays to the HDMI outputs
5. Connect any other signals such as IR, audio or control inputs
6. Power up the matrix
RJ45 Wiring
Both connectors must be wired identically.
IMPORTANT: The signals used by this extender set will not pass through any Ethernet device.
The Matrix and Receivers provided in this set will only work with the Xcalibur product range.
Please make sure that the Cat6 cable uses 4 pairs of 23AWG solid copper wires. Do not use
inferior copper clad cables as these exhibit high resistances.
It is recommended for the HX cable run between the Transmitter and Receiver units to be
continuous cable run of either cat5e/6/6a. Cat6a cabling is preferred for best signal quality.
IR Connector Wiring
The following diagrams detail the IR Eye/Emitter wiring connections for the Xcalibur matrix and
the Xcalibur-11 Receivers.
Figure 1 - Xcalibur IR Eye
Figure 2 – Xcalibur IR Emitter
Figure 3 - IR Eye Connector Wiring
Figure 4 - IR Blaster Connector Wiring
The IR emitter (blaster) connector can be a 3.5mm mono style, in which case the entire sleeve
is the +ve signal. IR signals with a carrier frequency in the range of 25-60 KHz can pass through.

IR Routing and Pass-Through
IR Inputs
The numbered IR IN connectors on the rear of the matrix units always go directly to the IR OUT
of the Xcalibur-11 receiver connected to the identically numbered HX output in a one-to-one
relationship. The IR IN ALL connector sends the IR data to all HX outputs simultaneously.
IR Outputs
The numbered IR outputs will follow with the video routing selections. The IR OUT ALL port sums
IR signals from all connected receivers. Take care when using this port to ensure that only one
Xcalibur Receiver is passing the IR signal to ensure proper output of that signal.
Coax Digital Audio Outputs
The coax digital audio outputs support any audio up to 5.1 channels. Any HDMI input with more
than 5.1 channels will have no sound at the digital audio output when routed to that output.
Analogue Audio Outputs
The differential analogue audio outputs only output the Front Left and Front Right channels
when the HDMI input audio has more than 2.0 channels.
RS232 Control Port Wiring
The RS232 control port 9-way DSUB connector uses transmit (TxD), receive (RxD) and Ground
only. The wiring of this connector is as follows:
Xcalibur Matrix DSUB Pin
PC DSUB Pin
2 (TxD)
3 (RxD)
3 (RxD)
2 (TxD)
5 (GND)
5 (GND)
RS232 Commands
All the following RS232 commands must be sent to the RS232 D-type connector on rear of the
Excalibur matrix units. The default RS232 settings are:
115200 baud, 8 data bits, no parity and one stop bit.
All commands are in lowercase and any spaces shown must always be included. Commands
should be sent as a single burst, as manual typing will often result no response being returned
or the error code E00 or E01.
Every command must end with an exclamation mark (!). Any carriage-return (0x0d) or line-feed
(0x0a) characters sent will be ignored by the device.
Every response message will terminate with a carriage-return and line-feed (0x0d 0x0a)
character sequence.
In the following tables, x, y and z represent parameter values that are presented in the
description of the respective command.

Video Keep-Alive Commands
Whenever the Video Keep-Alive (VKA) feature is enabled for an output, that output will display
a Test Pattern when the input HDMI signal assigned to that output is lost. This will keep devices
such as projectors active, stopping them from going into standby mode. When a valid input
signal assigned to the output is detected, or VKA time-out, then VKA is stopped.
The VKA mode can be set to time out after several minutes or remain on indefinitely. The VKA
Test Pattern is displayed on both the HDMI and HX outputs for that output port.
For the following commands y is the desired output (or 0 for All Outputs).
RS232 Command
Description
Response Example
s out y vka time z!
Set the time, in minutes, after which the VKA
mode is automatically disabled, for output y.
Where z is a value in the range of 0 to 240.
Note: a value of 0 or greater than 240 will set
the VKA mode to never time out.
video keep-alive timeout:

Down-scaler Mode
The HDMI and HX output can be independently set to down-scale any 4K input video to 1080p
at the same refresh rate. The Auto Down-scaler option will use the EDID of the display to
determine the scaling mode.
RS232 Command
Description

EDID Control
These matrix products provide several EDID management commands to ensure that the source
is able to provide the correct image resolution to the display device.
RS232 Command
Description
Response Example
s edid in x from z!
Set HDMI input x to use one of the built-in
EDID settings. The z value is given in the tables
below.
Input 2 EDID:1080p, Stereo
Audio 2.0
r edid in x!
Get the current EDID setting for HDMI input x
Input 1 EDID: 4K2K_444,
Dolby/DTS 5.1
r edid data hdmi y!
Get the EDID data from HDMI output y
See below
r edid data hx y!
Get the EDID data from HX output y
See below
For all EDID commands that either require or return EDID data, the EDID data is always given as
pairs of ASCII characters representing the hexadecimal data, for example, where … represent
the remainder of the EDID data:
s edid user1 00 FF FF FF FF FF FF 00 …!
The <edid data> marker shown in the above table is where the actual EDID, as shown in the
above example, should be placed.
The “r edid data!”, “r edid data hdmi x!” and “r edid user1!” all return their respective EDID
data values as ASCII encoded hexadecimal values.
Note: 4K@60 HDR 2.1/51/7.1 resolutions are with 4:2:0 YCbCr colour space setting.

Sending RS232 Commands to HX Receivers
The matrix units are able to send RS232 commands from the HX outputs to the connected
Xcalibur-11 Receivers Using the control RS232 port as well as the Web interface. The HX ports
can be individually selected or the RS232 command can be sent to all the HX outputs.
RS232 Command
Description
Response Example
s rs232 y a
b:****END!
Send an RS232 command to the HX output port
y at the specified baud rate.
y = HX Output number
y = 0 All HX outputs
a = 0 ASCII Format
a = 1 Hexadecimal Format
b is baud rate from one of the following:
b = 1 115200 b = 2 57600 baud
b = 3 38400 b = 4 19200 baud
b = 5 9600 b = 6 4800 baud
b = 7 2400
**** is the actual command transmitted to the
HX Receiver, this must be 80 characters or less.
END! marks the end of the command and is
required
Hx baud rate is 9600, ascii
format command:****
Sending an ASCII Command
The following example shows how the ASCII command POWR=ON<cr> is sent from HX output 3
using a baud rate 19200:
s rs232 3 0 4:POWR=ON
END!
Note: the above example is two lines and that the <cr> (represented by the  character) is
entered by using the Enter on the PC keyboard.
Everything between the colon (:) and the END! marker, are sent exactly as entered and character
the case will not be altered.
Sending an Hexadecimal Command
There are occasions where certain ASCII control characters are not immediately available from
the PC keyboard, this is where hexadecimal notation is used. The following example is for a
display power on command, this time sent to HX port 1 at 9600 baud:
s rs232 1 1 5:99A2B3C402FF0100END!
This example shows several values that are not easily accessible as a single character from a PC
keyboard and need to use hexadecimal notation. All the values between the colon (:) and the
END! marker are converted to the correct binary values before being sent to the HX output port.
