Notes: When using IR receivers connected to IR IN, the IR carrier must be present. If it is not, then send
the RS232 command %0901. to force carrier mode (38 KHz) to ensure the IR data is sent with a
carrier signal between Matrix Switcher and far-end HDBaseT Receiver.
To revert to using the native carrier signal, send the RS232 command %900. to activate native
carrier mode.
Native carrier mode (factory default)
This mode must have the IR carrier signal present. The IR detectors supplied with the Matrix
Switcher are fully compatible with this mode setting.
Forced carrier mode
A fixed carrier of 38 KHz is forced onto the raw IR data. This mode should only be used when using
an IR detector that outputs the raw IR data without the normal carrier signal.
Using the Matrix Switcher
The input signals may be routed to either a single output, or to multiple outputs using the front control
panel or RS232 / Ethernet port commands or the remote controller.
Front panel enquiry/selection may be done by either pressing an input button first or by pressing an
output button first.
The first time any front panel button is pressed the matrix switcher provides an inquiry mode that indicates
the current port connection status. New selection can subsequently be made.
If there is no activity on the front panel button for more than 3 seconds, the matrix switcher will return to
the idle mode and turn all the button LEDs off.
Pressing an Input button first
When any input button is pressed while the matrix switcher is in idle mode, the output channel buttons
associated with that input light up as follows:
1. All the outputs associated with the selected input will light up
2. If no output buttons are off, then that input is not connected to any output
While in this mode:
1. The output buttons can be individually pressed to toggle the connection status for the selected
input (on or off).
2. A range of output channels can be selected by pressing the two start and end button of the
desired range simultaneously. For example, pressing buttons 2 and 6 will set the selected input to
outputs 2, 3, 4, 5 and 6 in one go. You may repeat steps 1 & 2 as many times as required.
Pressing an Output button first
When an output button is pressed while the matrix switcher is in idle mode, the input channel button
associated with that output will indicated the current connection status.
While in this mode, the input associated with the selected output may be changed by pressing another
input button.
Front Panel LED Status Updates
Whenever an external selection update is made to the matrix switcher, either from the RS232 port or the
LAN port, the button LEDs will light up briefly to indicate the new status.
