RS-485 Address
A data bus address must be configured
for applications that implement remote
control of Model 5150 functions. While up
to 16 Model 5100-Series modules can
“share” the RS-485 data bus, each module
must have a unique address. Selecting the
device’s address involves setting four con-
figuration switches on the MCU board. The
switches are a “piano key” type with their
up position being defined as off and their
down position defined as on.
An initial overview of the configuration choic-
es is provided in the following paragraphs.
Following these paragraphs are details on
how to determine a module’s current con-
figuration and how to revise parameters as
required.
SDI Input Select
The Model 5150 is capable of having its SDI
input in the form of a coaxial signal (BNC
connector) or an optical signal (SFP mod-
ule). All versions of the Model 5150 support
the coaxial (BNC) input. The optical input is
an option and may or may not be present
on the specific module you are configuring.
Configuring this function can be performed
using the Model 5190 Remote Access Mod-
ule or by way of a text file stored on a USB
flash drive.
SDI Output Image Format/Rate Mode
One setting is used to configure how the
format and rate of the internal SDI genera-
tor is selected. (The internal SDI generator
creates the short-duration solid-gray video
image and plays back the stored “720” and
“1080” images.) In the Auto mode the format
and rate will automatically “follow” that of a
connected SDI input. This allows the Model
5150 to automatically “learn” the specific
format and rate used by a broadcast facility
or live event. In the Locked mode the format
and rate of the internal SDI generator will be
“locked” so that it will not change. Configur-
ing this mode can be performed using the
Model 5190 Remote Access Module or by
way of a text file stored on a USB flash drive.
Delay Before Stored Image
The Model 5150 can output a solid-gray
video image prior to the stored image being
generated. This is provided as an innocuous
indication to downstream equipment that a

Configuring Everything Else
Many other Model 5150 operating param-
eters can be configured using the Model
5190 Remote Access Module or by way of
a text file. Details on how to use the Model
5190’s menu pages are covered in other
documentation. Understanding how to cre-
ate and use a configuration text file will be
covered in this guide.
