MODULE OVERVIEW
The 5140 provides analog distribution of composite video signals, NTSC and PAL. It can
equalize up to 1000 feet (300 meters) of coaxial cable. The purpose of equalization is to
compensate for the losses that occur when a video signal travels through a length of
coaxial cable. Due to their differing characteristics, different types of cable will require
different equalization networks on the 5140. Cable type must be specified when the
module is ordered.
Input signal validity is displayed locally and can be monitored through the Avenue remote
control options. Gain and EQ parameters 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 the Humblocker™ circuit
then goes on to the equalization circuitry. After that, the signal goes through the gain
adjustment circuitry. Nine outputs are provided.
Power is derived from the ± 12 volt frame power. It is regulated to the required +5 volts
for the module by the 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.
HumBlocker™
HumBlocker™ technology on the 5140 will automatically process the analog signal to
remove power line hum and other types of interference. This is a superior solution to the
problem of recovering analog signals in noisy environments or in the presence of groundloops. Differential inputs can only provide their full benefit if the shield of the input
signal is never connected to local ground. Asimple patchbay or cable demarcation box can
render differential inputs useless. The HumBlocker feature on the 5140 will actually
identify and cancel power line interference within the video waveform itself.
Because the HumBlocker system is designed specifically for analog composite video, it
must be turned off if the module is being used to distribute other signals (AES, TriLevel
Sync, etc.)

APPLICATIONS
As shown in the example below, the 5140 DA can be utilized to distribute a master
reference source throughout a facility. The master reference genlock signal is inserted into
the 5140 input then distributed to up to nine destinations. The Avenue remote control
system can be set up to report an alarm if there is a loss of house reference.
The application below shows the 5140 used as a video presence detector. The Program
Output signal from a master control device is fed to the 5140 input and then the output of
the DA is sent to the transmitter. An alarm can be set in the Avenue control system to
send an alert if the sync signal to the transmitter is lost.
