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.

INSTALLATION
Plug the 5140 module into any one of the slots in the 1 RU or 3 RU frames and install the
plastic overlay provided onto the corresponding group of rear BNC connectors associated
with the module location. Note that the plastic overlay has an optional adhesive backing
for securing it to the frame. Use of the adhesive backing is only necessary if you would
like the location to be permanent and is not recommended if you need to change module
locations. This module may be hot-swapped (inserted or removed) without powering down
or disturbing performance of the other modules in the system.
CABLING
Refer to the 3 RU and 1 RU backplane diagrams of the module below for cabling instructions. Note that unless stated otherwise, the 1 RU cabling explanations are identical to
those given in the 3 RU diagram.
Connect the analog video
source signal to be distributed
into the Input BNC.
NOTE: This input is self-terminated on the module, if the
module is removed, the input
will become unterminated.
Connect up to nine
analog output destinations
to the Out 1-9 BNCs.
The 15-pin connector is not
used in this application.

MODULE CONFIGURATION AND CONTROL
The parameters for each Avenue module must be configured after installation. This can be
done remotely using one of the Avenue remote control options or locally using the module
front panel controls. Each module has a REMOTE/LOCAL switch on the front edge of
the circuit board which must first be set to the control mode you will be using.
The configuration parameter choices for the module will differ between Remote and
Local modes. In Remote mode, the choices are made through software and allow more
selections.
If you are not using a remote control option, the module parameters must be configured
from the front panel switches. Parameters that have no front panel control will be set to a
default value. The Local switches are illustrated in the Front Panel Controls and
Indicators section.
Avenue module parameters can be configured and controlled remotely from one or both of
the remote control options, the Avenue Touch Screen or the Avenue PC Application. Once
the module parameters have been set remotely, the information is stored on the module
CPU. This allows the module to be moved to a different cell in the frame at your discretion without losing the stored information. Remote configuration will override whatever
the switch settings are on the front edge of the module.
The 5140 can equalize up to 1000 feet (300 meters) 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. Alabel on the module
identifies the cable types for which it is appropriate. In addition, the Cable Type
indicator can be viewed through Avenue PC or the TouchScreen control panel.
The purpose of equalization is to compensate for the losses that occur when a video signal
travels through a length of coaxial cable. For lengths under 100 feet these losses are negligible, but for longer cables loss compensation is needed to preserve signal integrity.
Without equalization or compensation, long cables will introduce both gain and frequency
response errors.
Gain Adjustment
The gain errors are easy to correct at either the sending or receiving end of the cable by
simply boosting the overall signal. The frequency response errors are a more complex
problem. Although a long cable will attenuate the entire signal, the higher frequencies
are more significantly affected than the lower frequencies. With composite video, this
means that the chroma information carried in the subcarrier is rolled off with respect to
the luminance content. Adjusting the gain of the path will not correct the frequency
response.

EQ Adjustment
The 5140 has two controls for cable equalization. The Coarse Eq control selects the
approximate length of the cable to be equalized, while the Fine Eq control is used to
precisely adjust the exact amount of equalization. The total equalization will be the sum
of the Coarse and Fine Eq settings.
The Coarse Eq setting is made through Avenue PC or the TouchScreen when the module
is in Remote. When the module is in Local, the Coarse setting is made with a rotary
switch located in the center of the module. It will most likely be necessary to remove the
module from the frame in order to adjust this switch. The Coarse ranges are:
0 - 200 feet 0 - 60 meters
200-400 feet 60 - 120 meters
400-600 feet 120 - 180 meters
600-800 feet 180 - 240 meters
800-1000 feet 240 - 300 meters
Once the Coarse Eq setting is made, the Fine Eq control is used to bring the total equalization up to the proper amount. The Fine Eq control has an adjustment range of 0 to
250 feet (0 - 75 meters).
The final results should be verified by passing a known, reference signal through the
path. If using color bars, the Fine Eq would then be used to fine-tune the chroma
amplitude setting. ASweep or Multiburst signal can also be used to verify (and adjust if
needed) for flat frequency response.
For setting the parameters remotely using the Avenue PC option, refer to the Avenue PC
Remote Configuration section of this document.
For setting the parameters remotely using the Avenue Touch Screen option, refer to the
Avenue Touch Screen Remote Configuration section of this data pack following
