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.
