IR REMOTE CONTROL
The AT-PROHD48M-SR comes with 32 button IR remote control, which could be used to
control the switcher when pointing at it or controlling the switcher from a remote location
by pointing the remote control to the IR Eye connected to the HDMI receiver.
For users who would like to use a 3rd part IR remote control or IR remote system, we
recommend either learning IR codes off the remote or copying and pasting the IR HEX
code into the remote control software. The le with HEX codes could be found on Atlona
website under downloads for AT-PROHD48M-SR.
There are 2 scenarios which codes to use:
• User will need to learn all 32 x codes in order to control each location when pointing at
the switcher
• User will only need to learn 4 x codes if there will be a separate remote for each re-
mote location
Note: The switcher can only accept and route IR signal which doesn’t exceed 38
KHz. In other words, if you are trying to send IR signal from the remote location
though out HDMI receiver and the IR signal is higher than 38 KHz, the IR signal
will not pass though.
