user, please abide by the following procedures in installation, use and
maintenance:
1. The system must be earthed properly. Please do not use two blade plugs
and ensure the AC power supply ranges from 100v to 240v and from 50Hz
to 60Hz.
2. Do not install the switcher in an environment where it will be exposed to
extreme hot or cold temperatures.
3. This unit will generate heat during operation, please ensure that you allow
adequate ventilation to ensure reliable operation.
4. Please disconnect the unit from mains power if it will be left unused for a
long period of time.
5. Please DO NOT try to open the casing of the equipment, DO NOT attempt to

5. System Operations
5.1 Front Panel Control
The front panel features four input and output selection buttons for switching the I/O
connection.
▪Switch on/off output channel:
Press buttons 01 –12 on the front panel to switch the corresponding output
channel.
▪Lock/Unlock output channel:
Long press buttons 01 –12 for 3 seconds or more on the front panel to
lock/unlock the corresponding channel. The corresponding LED will flash 3
times.
Note: The locked channel can’t be controlled via the front panel buttons,
RS232 or the GUI.
▪Select the Output Voltage:
Press SELECT on the corresponding output channel to select the output
voltage as 5V, 12V or 24V.
Note: After switching the output voltage, the output channel will be turned off.
This is to protect an over voltage situation on the connected device. Ensure
your device is able to accept the selected voltage and turn the output on via
the front panel.
▪Restore Factory defaults:
On the rear panel, simultaneously long press SELECT on channel 1 and
channel 2 for 3 seconds or more. The device will be restored to factory
settings.
