Ensemble Designs 5150 DA for Analog Video, AES and Tri-Level Sync - Manual (Page 2)

MODULE OVERVIEW
The 5150 module provides analog distribution of composite video signals, NTSC and PAL
and AES audio. Nine buffered composite video outputs can be accessed from the one
analog video input source.
Input signal validity is displayed locally and can be monitored through the Avenue remote
control options. Gain can be adjusted locally as well as remotely. Remote control is
accessed via the optional Avenue Touch Screen Control Panel and Avenue PC Control
Applications.
As shown in the block diagram below, the signal passes through an input buffer circuit
then goes on to the gain adjust circuitry. Overall gain can be adjusted locally with the trim
pot on the module front panel or remotely with one of the remote applications as
explained in the Front Panel Controls and Indicators section of this data pack.
Power is derived from the ± 12 volt frame power. It is regulated to the required +5 volts
for the module by on-board regulator. The module is fused with a resettable fuse device. If
the fuse opens due to an overcurrent condition, the module will lose power. After pulling
the module, the fuse will reset automatically requiring no replacement fuse.
The on-board CPU can monitor and report the module ID information (slot location,
software version and board revision) and signal presence detection which can be reported
by the optional frame System Control module to the optional interfaces available.
