automatically.
▪ Manual switching is enabled in the auto switching mode and does not exit it.
5.1.3 Rebooting device
The Transmitter can save the last configuration before losing power. If the last switching
mode is auto-switching, the Transmitter will automatically enter auto-switching mode
once rebooted, then detect all inputs and memorize their connection status for future
rebooting using. If the last selected input source is still available, the Transmitter will
switch to the input. Otherwise, it will switch to the first available active input source
starting at 1-HDMI.

Altimium 11 www.altimium.com
5.1.4 Signal removing
Once removing the current display signal, the Transmitter will detect all input signals
with priority from 1-HDMI to 4- USB-C. It will transfer the signal firstly detected to be
available to output devices.
5.1.5 Front Panel button Control
▪ The Receiver features video output port for connecting third-party display device,
press the ON or OFF button on Transmitter to turn on or turn off the third-party
display device.
▪ The Receiver features audio output ports for connecting speaker or AV amplifier,
press the VOL- or VOL+ button on Transmitter to turn down or turn up the volume.

screen), press the RELAY1 or RELAY2 button on Transmitter to close the contact
closure.
5.2 Third-party display Devices Control
Note: If the input source devices, HDMI output display devices support CEC, they can
be controlled via the following CEC operation.
This Auto operation control includes Transmitter HDMI OUT and Receiver HDMI OUT,
and the CEC function can be disabled or abled.
5.2.1 System On
When Switcher detects the TMDS or 5V input signal (default: 5V signal), it will perform
the following operation steps:
1) Send CEC ON command to third-party display devices;
2) Send RS232 ON + Delay time (default: 3s) +RS232 Display Input selection
command to third-party display devices;
3) Perform and control Relay1.

Altimium 12 www.altimium.com
5.2.2 System OFF
When Switcher detects all the input source devices were disconnected for XX time long
(default: 10 minutes), or receives the standby command, it will perform the following
operation steps:
1) Send CEC ON command to third-party display devices;
2) Send RS232 OFF command to third-party display devices, this command can be set
to send twice (default: 1 time), delay time default is 1s;
3) Perform and control Relay2.
