Video Generator/Audio Embedder Module
corporate facilities. The module’s perfor-
mance is completely “pro” with video and
audio quality, reliability, and installation flex-
ibility matching that of much larger-scale
equipment.
For operation the Model 5152 only requires
connection of a few signals. These consist
of SDI inputs and outputs, up to four unbal-
anced digital audio sources, an external
source of nominal 12 volts DC and, op-
tionally, two wires associated with a local
RS-485 data bus. Some applications may
also utilize the general-purpose input (GPI)
and general-purpose output (GPO) func-
tions (available only on modules with serial
numbers 00251 and later). Coaxial SDI
input and output support is standard. Opti-
cal input and output support is optional. The
acceptable DC input voltage range is 10 to
18, allowing a variety of power sources to
be utilized.
The Model 5152 uses standard connectors
for fast, convenient interfacing. Coaxial SDI
input and output signals use BNC con-
nectors. An optional video SFP fiber optic
module can be installed at the factory. The
module supports interconnection of single-
mode optical fibers using LC plugs. Digi-
tal audio signals interface with the Model
5152 by way of a 9-pin D-subminiature
connector. The DC power input and data
bus connections use a 4-position, 0.1-inch
header. The GPI and GPO connections use
a 3-position, 0.1-inch header. Low-cost IDC
(insulation-displacement connector) mating
sockets allow simple interconnection with a
variety of wire gauges. Twelve status LEDs
offer users both performance confidence
and troubleshooting assistance.
The Model 5152 is compatible with the
Studio Technologies’ Model 5190 Remote
Access Module. This will allow remote
configuration, monitoring and control, via an
Ethernet connection, of key module operat-
ing and status parameters. A local RS-485
data bus allows up to 16 of the 5100-Series
modules to be connected to a Model 5190.
Several Model 5152 operating parameters
can be configured to meet the needs of
specific applications. A USB flash drive
along with several DIP switches, are used
to convey the configuration to the module.
A simple text file that reflects the desired
configuration is created and stored on the
USB flash drive. When inserted into the
appropriate socket on the Model 5152 the
file is read and stored. Updating the Model
5152’s firmware (embedded software) is
also possible using a USB flash drive load-
ed with factory-supplied files.
Model 5152 Video Generator/Audio Em-
bedder Modules do not include a mounting
enclosure or chassis. They are intended
for mounting in custom 19-inch rack pan-
els, equipment boxes, broadcast furniture,
“NEMA” I/O boxes, or other specialized
enclosures. It is expected that integration
firms will create applications that use Model
5152 modules as part of complete broad-
cast, production, corporate, and government
solutions. Sophisticated users will be able
to easily create “one-off” solutions to solve
unique challenges.
SDI Inputs and SDI Outputs
High-definition SMPTE-compatible SDI sig-
nals with data rates of 1.485 Gb/s nominal
(HD-SDI) and 2.97 Gb/s nominal (3G-SDI)
can be connected. Virtually all of the com-
monly-utilized “720” and “1080” formats are
supported. Standard-definition SDI signals
with a data rate of 270 Mb/s nominal (SD-
SDI) are not supported. It was felt that users
looking for advanced solutions such as
