Thank you for purchasing the PRODUCT.
This PRODUCT is designed with the professional AV installers in mind. The many extensive
features assist in 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 cables should be routed away from any noisy sources and avoiding long runs in close
proximity to AC mains cables.

Using this Product
This Xcalibur-14 Splitter Extender product is designed to function only with the Xcalibur
Receivers (provided with the set). Important: The HX ports are not compatible with HDBaseT
devices.
1. Connect the video source to the HDMI input.
2. Connect the HX outputs to the HX input of the Receivers using Cat6 cable.
3. If a local display is required, connect it to HDMI OUT.
4. Connect the 24V DC PSU to the Xcalibur-14 (This will power the 4x Receiver units too).
5. Connect any external controls that are required to their respective ports: i.e. RS232 or IR.
6. Connect any audio amplifiers to the audio connections, as required.
7. Power up the system.
De-embed Audio Outputs
Balanced Analogue Audio output
The differential (Balanced) analogue audio output only provides the Front Left and Front Right
audio channels. When connecting to an unbalanced audio input, only connect to the L+, R+, and
Ground signal pins on the five way connector as shown in the following diagrams:
Figure 1 – Balanced Audio Out
Figure 2 – Unbalanced Audio Out
Coax (S/PDIF) Audio Output
The COAX audio output provides de-embedded digital S/PDIF audio data. It always outputs the
same number of audio channels as is present in the input HDMI signal.

PC Control Mode
The five Copy EDID commands only perform a copy if a display is detected at the respective
output. The EDID data is stored in the transmitter until it is overwritten by another EDID copy.
The factory default setting for these locations is 1080p60 with 2.0CH Audio.
The USER EDID switch settings select the USER EDID memory location. The factory default for
the USER EDID location is 1080p60 with 2.0ch stereo audio.

V1.0 9sy.uk
The Enable Test Pattern switch options allow manual selection of currently set Test Pattern, at
1080p 60Hz, 4K30 30Hz, or 4K60Hz resolution.
The PC Control Mode setting allows the use of RS232 commands to configure the EDID setting
for the HDMI input connector. The other switch setting will always take priority over the RS232
setting when the EDID switch is not in the PC Control Mode position.
RS232 Control Commands
All the configuration commands in the following sections must be sent to the RS232 connector
on rear of the SY-HX150-14-18G splitter.
Only the “r fw version!” command can be sent into the SERVICE USB on the front of the SY-
HX150-R-18G receiver using the SERVICE USB. Connecting to the SERVICE USB on the receiver
will appear as a serial port on the PC or laptop.
The serial port settings for all control commands 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 in the response unknown
command!
Every command must end with both the exclamation mark (!). A carriage-return (0x0d) and line-
feed character (0x0a) can be transmitted, but it will be ignored by the SY-HX150-14-18G.
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.

Test Pattern
The Xcalibur 14 splitter (SY-HX150-14-18G) can generate 6 different Test Patterns, with 3 possible
resolution settings. The selected Test Pattern is activated by sending the “s test pattern on!”
command and deactivated with the “s test pattern off!” command. The activated Test Pattern
is displayed on the LOOP OUT and all HX outputs simultaneously.
Note: Test pattern can also be activated via the 5W DIP switch.
The default Test Pattern is set to ‘Chequerboard at 1080p 60Hz’, but disabled (Test Pattern off).

should the HDMI input signal resume, or VKA time out. The following VKA options are available:
Output current Test Pattern – Maintain output video stream (Video Keep-Alive).
No timing output (default) – (VKA off) No output video; hence video drop-out.
The Test Pattern can be displayed permanently or for a programmable time interval.

Sending RS232 Commands through the Receivers
The following commands are to control the routing of RS232 commands to the Receivers.
Sending command to the Receiver requires the following steps:
1. Select the desired Receiver using the s rs232 bypass hx y! command.
Note: When all ports are enabled (y = 0), no Receiver RS232replies are sent back.
2. Set third-party device baud rate using s device baud w size x stop y parity z! command.
3. Send RS232 pass-through commands to the Receiver.
Note: To communicate with a different Receiver, repeat steps 1. & 2. with the new target
Receiver details.

4. To stop any further commands being sent through the Receivers, use the s rs232 bypass
hx 5! command to disable the RS232 output for all the HX output ports

System Configuration
RJ45 Wiring
Both RJ45 connectors must be wired identically.
IMPORTANT: The signals used by this extender set will not pass through any Ethernet device.
The Splitter 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 cables such as CCA, as these exhibit high resistances.

sy.uk 16 V1.0
It is best for the cable run between the HX (RJ45) connectors on this splitter and the connected
receiver units must be a continuous cable run of either cat5e, cat6a or cat7.
It is recommended for the cable run between the Xcalibur 14 and the Receiver units to be a
continuous run. Cat6a cabling is preferred for best signal quality.
IR Pass Through
The IR IN on the rear of the Xcalibur-14 Splitter unit sends the IR signal to all the remote Receivers
simultaneously. The IR OUT will mix the IR signals from all the receivers, so it is best to ensure
that only one Xcalibur 11 Receiver is sending IR signal at a time. The emitter connector can be a
3.5mm mono style, in which case the entire sleeve is the +ve signal.
