5. Operation
5.1. Powering on
Connect the power cords to the power supply units' IEC standard power input connector.
After switching the mains switch to the 'I' position the router starts up. If the mains switch
is not available or it was in the 'I' position, then the matrix starts up immediately when the
power cord is connected to the AC source.
During the initial self-test and loading of the latest settings ,,Booting..." appears on the
LCD screen. After the self-test, the router reloads its last configuration and it is ready to
use. In case of hardware failure, an error message is displayed.
Info: After switching ON, the router reloads the latest settings that were used before it was
turned off. The router has an internal emergency memory that stores all current settings
and tie configurations. This memory is independent from presets and invisible for the
user. This built-in feature helps the system to be ready immediately in case of power
failure or accidental power down.
Redundant power supplies
Some frame models have hot pluggable, redundant power supplies. Power supply units
(PSU) can be dismounted or installed during operation. Depending on the router's
configuration (number and type of I/O boards) one or two PSUs are needed to operate.
The extra PSU makes the system redundant. Please consult Lightware support about
your system configuration to ensure redundancy.
If more than one PSU is needed for supplying the matrix, please make sure that the
second PSU gets power no more than 10 seconds after the first one is plugged in to
prevent overload on the first PSU.
If one PSU is enough to supply the whole matrix, then the other one(s) can be left
unplugged.
5.2. Front panel operations
5.2.1. CONTROL LOCK
Front panel button operations can be enabled or disabled using CONTROL LOCK button,
while RS-232 / RS-422, USB and Ethernet control is still enabled. If the button is not
illuminated, front panel button operations are enabled. If it illuminates red continuously,
front panel operations are inhibited (including LCD menu).
Press and hold the CONTROL LOCK button for 3 seconds to toggle the control lock state.
5.2.2. TAKE / AUTOTAKE modes
The router has two different switching modes: TAKE and AUTOTAKE. If the
TAKE / AUTO button is unlit, TAKE mode is active. When the TAKE / AUTO button
continuously lights green, AUTOTAKE mode is selected.
Press and hold the TAKE button for three seconds to toggle between TAKE and
AUTOTAKE modes.
TAKE mode allows the user to connect or disconnect multiple outputs to an input at once.
This mode is useful when time delay is not allowed between multiple switching. The
commands are only realized when the TAKE button is pressed. If no button is pressed for
two seconds, all preselected actions (which were not realized with the pressing TAKE)
will be ignored, and the router returns to its idle state.
AUTOTAKE mode is useful when immediate actions must be done or fast switching is
needed between sources on a particular destination. In this mode switching occurs
immediately upon pressing one of the input selector buttons.
