4. Be sure that your HDMI 4x1 TM Switcher is set to “Normal” operating mode.
To change operating Modes: Power must NOT be applied to your HDMI 4x1 TM Switcher unit.
The power supply MUST be disconnected (either from the back of your unit or from the wall
outlet) to have a complete power shutdown - reset.
Only select “Program” mode when you need to perform a Firmware Upgrade of your HDMI
4x1
TM Switcher unit, as provided and instructed by Key Digital ® . Firmware Upgrade instruc-
tions are provided later in this Operating Manual.
If the rear-panel Mode switch is set to “Program” mode and your HDMI 4x1 TM Switcher unit is
powered ON, or even if the power supply is connected and the unit is turned OFF, the unit is
expecting a firmware upgrade and will not operate properly. If you did not intend to perform
the firmware upgrade, turn your HDMI 4x1
TM Switcher unit OFF. Then, you must physically
disconnect power to your unit, set the rear-panel Mode slide switch to “Normal” mode,
physically reconnect power to the unit, and then turn the power back ON to your unit for
normal operation of your HDMI 4x1
TM Switcher.
5. Connect the external power supply to your HDMI 4x1 TM Switcher unit.
Do not connect the external 6 Volt DC supply (provided) to the back of the Switcher until all
your Video and Audio connections to the HDMI 4x1
TM Switcher are complete (as described in
the prior step of this Operating Manual) and you have set the Mode switch to “Normal”
mode.
Once you have made all the A/V connections to your HDMI 4x1 TM Switcher and the Mode is
set to “Normal”, plug in the external 6 VDC @ 5 Amp Power Supply (provided with your unit)
to the jack on the back of the unit and connect the power cord into an appropriately rated
wall outlet or power strip. You may now turn your HDMI 4x1
TM Switcher unit ON using the
front-panel pushbutton, the IR Remote Control, or RS-232.
Mode: Program - Normal
Physically disconnect the power to your unit before setting the
