Model 5150
Video Generator Module
selected SDI input will serve only as
a timing reference signal. In this latter
mode, the internally-generated image will
always be sent to the SDI output(s).
GPI= configures the GPI (general-purpose
input) function.
DISABLED selects that the
function is not active. Future versions of
the MCU firmware may implement other
GPI actions. Note that if the hardware ver-
sion of this specific Model 5150 does not
support the GPI function (modules with
serial numbers 00250 or less) this text line
will not appear.
GPO= configures the GPO (general-pur-
pose output) function. DISABLED selects
that the function is not active. SDIVALID
selects that the GPO output will be high
when a valid SDI signal is connected to the
selected SDI input (coaxial (BNC) or opti-
cal). SDINOTVALID selects that the GPO
output will be high when a valid SDI signal
is not connected to the selected SDI input
(coaxial (BNC) or optical); the GPO output
will be low when a valid SDI signal is con-
nected. Note that if the hardware version
of this specific Model 5150 does not sup-
port the GPO function (modules with serial
numbers 00250 or less) this text line will
not appear.
Configuration Text File
A text file can be created to specify how a
Model 5150 should be configured. Saved
on a USB flash drive, the file must have a
name of CONFIG.TXT and be stored in a
folder directly under the root with a name
of M5150. When the USB flash drive is
plugged into a Model 5150 the file will
automatically be read and the configura-
tion stored. Immediately after the file is
read the STATUS.TXT file will be written to
the M5150 folder. The contents of this file
will reflect the configuration that’s pres-
ent after the contents of the CONFIG.TXT
have been read. This will provide immedi-
ate feedback that the desired configuration
has be implemented.
The following paragraphs detail the con-
figuration choices. This information is also
shown in the [OPTIONS] section of the
STATUS.TXT file, described previously
in this guide.
The text lines that follow the [CONFIGU-
RATION] heading should remain in the
same order as shown in the example. (But
technically they are not required to do so.)
All configuration items are not required to
be present but for clarity it’s recommended
that they are. The text is case sensitive and
must follow the example.
SDIINPUT= selects which physical SDI
input on the module will be active. There
are two choices. BNC selects the coaxial
(BNC) SDI input to be active. SFP selects
the optical SDI input to be active.
FORMAT= selects the SDI Output Image
Format/Rate Mode. There are two choices.
AUTO selects the Auto Select (Follows
Input) mode.
LOCKED selects the Locked
(Does Not Follow Input) mode.
[CONFIGURATION]
SDIINPUT=BNC
FORMAT=AUTO
MOTION=ON
SDIMODE=NORMAL
GPI=DISABLED
GPO=SDIVALID
