IR Operations
IR Matrix Switching
The 8 IR OUT ports on the matrix and the 8 IR IN ports on the far-end receivers make up an
8x8
IR matrix:
Control Local Devices or the MHDBT-88P Remotely
The IR signal is sent to the corresponding IR remote, where it is transferred from the HDBT receiver to the
matrix via the Cat6 cable and then to the IR OUT port where it is received by controlled device.
Switching Operation
The 8 IR IN ports correspond with 8 HDMI input ports separately by default.
Sending the command
: [x1]R[x2]. (See
RS232 Control
)
[x1] is the desired IR OUT port of the matrix, the IR transmitter connected to this port can be placed
at IR receiving area of output device or in front of the MHDBT-88P itself.
[x2] is the desired output channel number of the MHDBT-88P. There must be an HDBT receiver with
an IR detector connected.
Example: Send the RS232 command
3R2.
to transfer the received IR signal from zone 2 to IR OUT port 3.
Note:
When switching all the 8 IR input signal channels to the same IR out channel, it will not be possible
to control the 8 far-end IR receivers at the same time.
IR Carrier Enforcing
Factory Default
a)
The received IR signal can only be transferred to the IR OUT port of the matrix only if the IR receiver
connected with HDBT receiver also has an IR carrier signal.
b)
The received IR signal can only be transferred to the IR OUT port of the matrix only if the IR receiver
connected with
IR
ALL IN
port of the matrix also has an IR carrier signal.
If the IR receiver connected to the HDBT receiver or IR ALL IN port of the matrix does not have an IR
carrier, then send the command %0901. to force the infrared carrier enforcing to be presented on the IR
OUT port.
