VideoBloX MODULES
The pin-out of this connector is automatically modified depending on configuration for the
chassis being a master or slave. Generally, this connector may be wired pin to pin
between one master and multiple slave chassis.

POWER SUPPLY MODULE

This module converts the main input power to an unregulated low voltage DC supply. The
latest version of the power supply can accept AC input ranging from 115 V to 240 V 50 /
60 Hz. It is additionally possible to power a VideoBloX chassis from an 18 to 24 VAC or
18 to 24 VDC supply. Power indications are visible from the front of the chassis. The
power supply is equipped with the necessary protection and filtering to ensure regulatory
compliance. It is possible to bring backup power into a chassis so that operation is not
affected by the failure of the main input power supply. The power supply module provides
an unregulated DC output to the backplane and each VideoBloX module is equipped with
independent voltage / current regulation circuitry. The VideoBloX power supply has
adequate capacity to power all modules within a chassis and also a limited number of
external control keyboards.
A system reset push button is accessible from the front panel, after removal of a cover
plate. The power supply module also incorporates communication drivers, used to
interconnect multiple sub-racks for assembly of large matrices.
