OPERATING MODES

7.2 Cross point- Switch
In “Cross point- Switch“ operating mode, each port of the ACX4000 Switch can be used
either as an input (to a Local Unit) or as an output (to a Remote Unit). Thus any combinations
between 1x input/7x output and 7x input/1x output are possible. The device offers no channel
monitoring in this mode so you must ensure the correct connection of the CATx- cables.
Incorrect cabling may switch two inputs or two outputs to each other and this could damage
your equipment!
An incoming DVI (+audio) signal can be switched and extended to one or more outputs
allowing you to output the signal to several displays at the same time (broadcast function).
The signal from the CPU (signal source) is transmitted over a Local Unit and CATx- cables
to the ACX4000 Switch. From the ACX4000 Switch, the transmission continues over CATx-
cables to up to 7 Remote Units. Alternatively, a further ACX4000 Switch (slave) can be used
between the first stage switch and further Remote Units. Therefore complex switching modes
can be achieved.
During operation, the allocation of ports as input or output is fixed. Devices must be attached
according to the following diagrams.
The distance between a Local Unit and ACX4000 Switch or between a ACX4000 Switch and
Remote Unit or between two ACX4000 Switches may amount to in each case up to 140m
allowing installations in distributed applications.
The control of the switching status is made by the integrated, serial interface. Switching
commands can be converted directly here. Switching combinations can be additionally stored
as macros. These can be called up with a short command or by using the push-button on the
device. Using the serial interface, macros can be selected directly; with the push-button, the
macros are successively activated.
