Video Generator Module
loss of SDI has occurred. The solid-gray 
image can be selected to be present for a 
fixed duration of one to seven seconds. It 
can also be disabled allowing the stored 
image to be output as soon as a loss of 
an input SDI signal is detected.
Moving Image Overlay
A “moving” graphic image can be overlaid 
onto the stored “720” and “1080” images 
when either one is being output by the Model 
5150. The image is a red-colored box that 
slowly moves around the screen. This simple 
icon provides an indication to personnel 
located downstream of the Model 5150 that 
the SDI signal is active. This can be impor-
tant to ensure that a distinction can be made 
between an active image and an image that’s 
the result of the last valid frame being held 
and displayed by a piece of equipment even 
though its SDI input is no longer present.
When the function is off the stored images 
(“720” and “1080”) will be displayed without 
the moving image being added. When the 
function is on the moving image will be 
added. Configuring this mode can be per-
formed using the Model 5190 Remote 
Access Module or by way of a text file 
stored on a USB flash drive.
SDI Input as Timing Reference
In most applications it’s desired that a sig-
nal connected to the selected SDI input will 
automatically be routed to the SDI output(s). 
But in special cases the Model 5150 may be 
used as a full-time video generator. In this 
latter case the ability to connect an external 
timing reference would be desirable. This 
would allow the SDI output(s) to be “locked” 
to a master or “house” timing signal. An 
operating mode selection allows an HD- or 
3G-SDI signal to serve as a timing reference.
When the SDI Mode is set for Normal 
a signal connected to the Model 5150’s 
selected SDI input will pass through to the 
SDI output(s). When SDI Mode is set for 
RefOnly the timing, rate, and format of the 
input SDI signal will impact the internally-
generated video image output. The video 
information associated with the input signal 
will not be routed to the SDI output(s). 
Configuring 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.
GPI – General-Purpose Input
Depending on the hardware version of a 
specific Model 5150 module there may be 
a GPI function available. The GPI (general-
purpose input) will allow connection of an 
external contact closure. The control will 
then control a Model 5150 function. As of 
the writing of this guide no function is avail-
able for control by way of the GPI. Config-
uring this function can be performed using 
the Model 5190 Remote Access Module or 
by way of a text file stored on a USB flash 
drive.
GPO – General-Purpose Output
Depending on the hardware version of a 
specific Model 5150 module there may 
be a GPO function available. The GPO 
(general-purpose output) provides a signal 
corresponding to the status of the selected 
SDI input. The GPO can be configured to 
be active high when the selected SDI input 
is correctly “locked” to the incoming SDI 
signals. The GPO can also be configured 
to be active low when the SDI input is 
“locked.” Configuring this function can be 
performed using the Model 5190 Remote 
Access Module or by way of a text file 
stored on a USB flash drive.
