2 Introduction
The Microtronix DX-2200 – SD/HD-SDI Text & Graphics Inserter is a high performance single input video
text and graphics inserter supporting alpha blended text and graphics overlay / on screen display (OSD) on
progressive, psf and interlaced SD and HD video formats. With support for embedded audio, VBI content
and metadata, it is designed for use in broadcast, professional video recording studios, high-end
surveillance applications and Point-of-Sale security systems requiring live insertion of high quality text
streams onto a SDI video signal.
The unit auto detects the format of the input video and outputs in the same format. Custom user
configurations and parameters can be stored in on-board flash for auto restoration during power ON/OFF
cycles. A fail-safe buffered SD/HD-SDI Loop Output is available for passing through the input signal
unmodified as may be required for broadcast applications.
2.1 Text and Graphics Overlay OSD Features
Features of the overlay OSD include:
1) Three layers for text and graphics fields
2) Display of 48 independent fields per layer
3) Fields support Text, Rectangles, Corner Markers, Target Marker and Image modes
4) Text Field of up to 195 characters
5) Alpha blending of the text for smooth edges
6) Frame Counter on the top overlay layer
7) Independent color selection of fields
8) Configurable background color of text fields
9) Transparency control
10) Independent ON/OFF control of fields
11) X-Y position control
12) Permanent retention of text fields in flash memory
13) PIP of auxiliary SD/HD-SDI input (product variant option)
The text and graphics are supplied to the DX-2200-TI through the RS-232 serial port. The user can
optionally store the text fields in the on-board flash in which case they will be retained power ON/OFF power
cycles.

4.1 Default Startup Configuration
The factory default configuration for the DX-2200-TI has no saved configuration in flash and the following
DIP switch settings:
Table 1: Default DIP Switch Settings
DIP Switch
Setting
1
Off 2 Off 3 Off 4 Off
When powered up in the factory default configuration, the unit will pass the input video through to the output
with no text overlay items added. The DX-2200-TI will automatically output in the same video format as is
detected at the input.
If there is no input signal (or if it cannot be properly detected), the SDI output will display black and the video
format will be 720p @ 60 fps.
A user specific setup can be stored in flash to enable the DX-2200-TI to start in a different configuration, for
example with a text overlay displayed.
4.2 LED Status Indicators

4.3 Video Format
The default video format is 720p @ 60 fps. If no input signal is connected at power-up (when operating in the
factory default configuration) the DX-2200-TI will output a black screen. The Text Overlay can be used
without input video connected.
When an SDI input with one of the supported video formats is connected, the unit will detect the video format
and switch the output to the match the detected video and attempt to lock to the clock frequency of the video
input. The video output will momentarily switch off as the video output is adjusted to match the format and
clock frequency of the input. When the clock frequency is locked, the video path is enabled and the input
video and ancillary data will appear at the output.
If the SDI input is disconnected, the unit continues to output in the last video format that was detected.
The default output video format can be changed by saving the configuration when the unit is operating with
the desired output format.
4.4 Picture-in-Picture (PiP)
Units equipped with the optional second SDI input connector (Input 2) are capable of PiP display using the
second SDI Input as the PiP source. The PiP video source can be asynchronous to the main video input or
can be a different resolution / frame rate. If the main input is an interlaced format, the PiP input must be
interlaced, and if the main input is a progressive format, the PiP input must be progressive. The size and
position of the PiP is programmable by software commands.
The PiP input will only function after the background video has been connected to Input 1. The PiP input
does not support audio or other ancillary data types. For interlaced formats, connection of a signal to the PiP
input may create an output video glitch as the unit synchronizes to the input.
4.5 Video Buffering and Frame Delay
For Text Inserter Mode (Mode 1) and Text Inserter with PiP (Mode 2), the DX-2200-TI includes a frame
buffer with a delay of 1 frame. The main video path has an additional delay of approximately 2000 clocks
(about 1 line in 1920x1080 video resolutions). The optional PiP video path has an additional delay that may
vary from 0 to 1 frame due to its support for asynchronous video inputs.
For Text Inserter with Scaling Mode (Mode 3), the DX-2200-TI has 2 frames of delay plus an additional delay
of approximately 4 lines.
4.6 Audio and Ancillary Data
The DX-2200-TI preserves ancillary data in the main SDI Input (Input 1) and passes it through to the output
to provide pass-through of audio, closed captions, and other ancillary data types embedded in the SDI video.
The optional PiP SDI Input (Input 2) does not support audio or other ancillary data types.
4.7 OSD Layers
The DX-2200-TI supports three video layers that are mixed on top of the SDI video input(s).
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 19 of 103
Figure 9: DX-2200-TI Layer Order
The top layer in the mix is referred to as Graphics Text Layer 1. This layer displays up to 48 Fields that
support text and graphics. The optional Frame Counter displays on this layer. Text Fields on this layer are
configured using either the Text Overlay Serial Commands or the Graphics Overlay Serial Commands. The
Frame Counter is configured by the Frame Counter Serial Commands.
The next two layers are Graphics Layer 2 and Graphics Layer 3. These layers each display up to 48 display
Graphic Fields that are controlled by the Graphic Overlay Serial Commands.
The 4th layer is the SDI video, and the 5th layer is the Black Background.
Within any one layer, no mixing of fields takes place. If two fields have pixels that occupy the same
coordinates, one will overwrite the other. When an update is performed to render the fields on a layer, the
fields are rendered in order of their field number. For example, Field 4 will always be rendered after Field 3
and will overwrite any pixels of Field 3 if they are in the same location in the frame.
When graphic fields on different layers are placed at the same coordinates, they mix according to their
transparencies and the layer order. When a field is fully visible, no content that is on the layers below it will
be visible. When the field is partly or fully transparent, it mixes with the layers below according to their
transparencies.
4.8 SERIAL & MANUAL Control
The SD/HD-SDI Video Text Inserter has two methods of control: SERIAL Control using the RS232 port, and
MANUAL Control using the DIP switch and Toggle switch. SERIAL Control allows control full of the
capabilities of the DX-2200-TI, and MANUAL Control provides a subset of functions.
SERIAL Control is always active. In the factory default configuration the Toggle Switch and DIP switch are
active.
The functions of the DIP switch and Toggle switch can be reconfigured by SERIAL Control commands to
customize the Switcher so that the controls provide the set of functions required for a specific user
application. The modified configuration can be saved on board in the flash configuration memory.
4.8.1 SERIAL Mode of Operation
When SERIAL control is used, the DX-2200-TI is controlled via commands sent to the DB9 Serial Control
Port.
The serial COM port of the computer connected to the DX-2200-TI should be configured for: 115,200 baud,
1 stop bit, and no flow control.
4.8.1.1 USB 2.0 to RS-232 Serial Port Adapter
The DX-2200 product is supplied with a USB 2.0 to DB9 RS-232 Serial Port Adapter Kit (PN: 811-USBRS232 Kit) to connect the DB9F Serial Port to a USB 2.0 port of a PC or laptop. The Kit consists of a USB
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 20 of 103
2.0 to RS232 DB9 Serial Adapter Cable (StarTech PN: ICUSB232V2) and a 6 foot male to female DB9
RS232 serial cable. Refer to Appendix B for more information.
4.8.1.2 DX-2200 Serial Port Control Commands
In the SERIAL mode, commands sent to the Serial Control Port control the operation of the DX-2200-TI.
Commands consist of ASCII alpha-numeric codes and are not case sensitive. All Serial Commands are
terminated with a carriage return (CR), a line feed (LF), or a semicolon. The use of a semicolon terminator
allows more than 1 command per line to improve readability of script files.
Commands may be sent directly to the DX-2200-TI one character at a time using a terminal program running
on a connected computer, or they may be developed in a text editor such as Notepad and then uploaded to
the DX-2200-TI by the terminal program. The second method has the advantage of allowing the commands
to be saved, viewed, edited and resent. The text editor used must save the configuration files as 8 bit ASCII
data.
Space or tab characters before a command or trailing a command are ignored, as are spaces or tabs
following a comma that separates parameters within a command. Any characters on a line following a tick (')
character are treated as comments. A comment may begin after a delimiter, or may follow a command with
or without spaces or tabs between the command and the comment.
ASCII string parameters are delimited with quotation marks. If a quotation mark or backslash character is
required within a string (for example to display as part of a text overlay), then it must be preceded by a
backslash character.
Valid and invalid Serial Commands are acknowledged with a ‘+’ and ‘-’ response respectively. Carriage
return, line feed, or semicolon characters without a preceding command are acknowledged with a ‘*’.
The command codes are extensible, additional commands and functionality can be added as required.
Contact Microtronix sales or technical support with your requirements.

4.8.1.5 Ancillary Data SERIAL Commands
By default, the DX-2200-TI preserves all ancillary data in the video signal. It is possible to control this
function if the ancillary data is not required. Disabling the ancillary data may slightly increase graphic update
speed in some situations.

4.8.1.6 Baud Rate SERIAL Command
The DX-2200-TI always powers up at 115200 baud. After power up, the baud rate can be changed using the
MBnnnnnnn command, where nnnnnnn is the new baud rate between 9600 and 1000000 baud.
The response to the baud rate command is transmitted before the baud rate is changed. It is recommended
to wait 100 ms after receiving the response before sending commands at the new baud rate to ensure the
DX-2200-TI is ready to receive commands at the new rate.
NOTE: The DX-2200-TI always starts at 115200 baud. Changes to the baud rate cannot be saved to flash.

MBnnnnnnn
Set the baud rate to nnnnnnnn where nnnnnnnn is a number

4.8.1.7 Picture-in-Picture Position, Size, and Zoom SERIAL Commands
These commands apply only to the Text Inserter with PiP mode of operation (Mode 2, see the Mode Control
Serial Commands).
The position and size of the Picture-in-Picture (PiP) display is selected through character commands sent
via the RS-232 port per Table 6 below.
There are two different methods of controlling the PiP size and position. The first method selects one of four
predefined positions and one of 16 predefined sizes using the commands PSnn, PAxxxx, PByyyy, followed
by P3, P4, P5, P6, P7, or P8 to set the positions and apply the settings.
For example: PiP in the bottom right corner using control method 1:
PS04 ' Set PiP size to be 4/16ths of the video width
PA20 ' Offset PiP 20 pixels horizontally from edge of the video
PB20 ' Offset PiP 20 pixels vertically from the edge of the video
P2 ' Apply settings and place PiP in bottom right corner
If the PS, PA, or PB commands are omitted in the above example, the previous setting, or the default will
apply. The default size for the PiP window is 6/16th of the video width (equivalent to the command PS06).
The default horizontal and vertical offset is 1 pixel + 1% of the screen width. If the P2 command is omitted
there will be no visible change to the PiP because it is this command that applies the parameters set the
other commands in the example.
The second method of setting PiP size and position does not use predefined sizes or positions, instead the
width, height, and the x and y position of the top left corner are set in terms of number of pixels by using the
commands PWxxxx, PHyyyy, PXxxxx, PYyyyy, followed by either PU or PR to apply the settings.
For example: PiP configured using method 2:
PX100 ' Set Top Left corner of PiP to x=100 pixels from the left
PY400 ' Set Top Left corner of PiP to y=400 pixels from the top
PW711 ' PiP window width = 711 pixels
PH400 ' PiP window height = 400 pixels
PU ' Apply the PiP Settings
This control method allows the aspect ratio of the PiP window to be changed, possibly resulting in stretched
or compressed video in the PiP window. If the PR command is used instead of the PU command, the height
parameter set for the PiP window by the PH command is ignored, and a value is calculated from the width to
provide a 16:9 aspect ratio for the PiP window.
In all cases, the PiP window must fit within the video. It is not possible to place the PiP window partly or fully
off screen. The DX-2200 will automatically adjust the gap, position and size parameters as needed to force
the PiP window to fit on screen. The minimum PiP width and height is 32 pixels. The DX-2200 will
automatically adjust the size to prevent the PiP windows being smaller than this size.
The PiP supports a limited zoom / cropping function that allows a selected region of the PiP video source to
be overlaid on the main channel instead of the entire frame. Two modes for selecting a region of the frame
are provided. The first method is controlled by a zoom factor specified in percent and a center location for
the zoom. The second method selects the top and left edge of the region, and the width and height. These
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 23 of 103
functions do not upscale the PiP input source. At most, each input pixel can generate 1 output pixel. The
DX-2200 automatically limits the values of the command parameters if the requested settings exceed the
valid ranges, for example by calling for magnification of the source.

4.8.1.9 Graphic Overlay SERIAL Commands
The Graphic Overlay Serial Commands support three layers that can each display up to 48 user-defined
Graphic Fields. Each Graphic Field can be configured to be Text, Rectangle, Corner Marker, or Target
Marker. The fields can be configured and positioned using the Graphic Overlay Serial Commands below.
Each Layer of the Graphic Overlay utilizes two frame buffers located in memory. One is these frame buffers
(the active buffer) generates a video output that is mixed on top of the input video, while the other buffer (the
spare buffer) is prepared for use.
The video output of the layer is updated by rendering all Graphic Fields into the spare buffer using the
parameters that have been set for each Field. The amount of time required to render the text to the spare
buffer depends on the number of pixels that must be drawn. Typically, the rendering process takes more
than one frame to complete. During this time, the active buffer continues to provide the Graphic Overlay
video output. After rendering is complete, the DX-2200-TI switches the active and spare buffers. The buffer
that was active before the update becomes the new spare buffer and is cleared by the unit to so that it is
ready for text to be rendered again when the next update occurs. Buffer switching is always performed at the
end of frame.
Many of the Graphic Field commands update the parameters of a Field (for example the visibility, color or
transparency), but do not update the video output. This allows the user to change as many parameters as
required before sending a command to show the updated output.
4.8.1.9.1 ACTIVE LAYER
The Graphics Overlay of the DX-2200-TI-03 has three layers named Graphics Layer 1, Graphics Layer 2
and Graphics Layer 3. The Graphic Overlay Commands do not include the layer number in the command
syntax. Instead, the commands always operate on the Active Layer. To select the Active Layer, the GLn
command is used where n is the layer number from 1 to 3. The default Active Layer is Graphics Layer 2.
Additionally, Graphics Layer 1 can also be accessed by the 'S' commands (See Graphic Layer 1 Overlay
SERIAL Commands). These commands always refer to Graphic Layer 1 regardless of the Active Layer.
4.8.1.9.2 GRAPHIC FIELDS
Graphic Fields are numbered 1 through 48. The Graphic Overlay Commands that apply to a single field
include the field number in the command, for example, the GnnS command enables display of field
number nn.
For any command that uses a field number, the field can be specified as either a 1 or 2 digit number in the
range 1 through 48.
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 28 of 103
Instead of specifying a single field, the commands can be applied to all fields on the layer by specifying a
field number of 0. For example G0S enables the display all fields on the layer and is equivalent to the
commands G1S, G2S, G3S… G48S.
Commands can be applied to a range of sequential fields using the syntax "f1-f2" for the field number where
f1 is the first field and f2 is the last field the command applies to. For example the command G7-10S enables
display of fields 7, 8, 9, and 10.
By default, all Graphic Fields are turned off and have default parameters. To display a field, the following
steps are required:
1) the field must be configured with the required field type
2) the parameters must be set appropriately
3) display of the field must be enabled
4) the layer must be updated
Some commands combine the last two operations in the above list, for example the G2S command enables
the display of Graphic Field 2 (on the active layer) and also updates the layer.
The following commands are a simple example that displays a rectangle. These commands are intended for
use with the DX-2200-TI in the factory default configuration:
G1M2 ‘ Set Field 1 to be a Rectangle Field

G1S ‘ Enable display of Field 1 and update the layer
4.8.1.9.3 RESET GRAPHIC FIELD
A Graphic Field can be reset to its default values with the GnnZ command where nn is the Graphic Field
number to reset. The GZ command will reset all Graphic Fields on the Active Layer, and the G0Z command
resets the fields on all layers to default.
Resetting a Graphic Field will clear the Text string, set the line color to white with full visibility, set the
position to the top left corner, set the fill color to blue but fully transparent (not visible), and set the font to the
default for the current video resolution. The overall visibility of the Field is set to off.
Resetting fields does not automatically update the video output of the overlay. Any fields that are visible in
the video are not cleared until a command is received that causes the overlay to be updated.
4.8.1.9.4 GRAPHIC FIELD VISIBILITY
Each Graphic Field can be turned on or off independently. By default, fields are off. The GnnV, GnnS, and
GnnH commands control the visibility of field number nn. GnnS and GnnH turn visibility on and off
respectively, and GnnV toggles visibility between on and off. Using any one of these commands will also
cause the video output to be updated by rendering the fields to the spare buffer and performing a buffer
swap. For this reason, it may be undesirable to use these commands when several text fields need to be
turned on or off because the video output will be updated as each command is executed. This will result in
the fields turning on or off one at a time.
The commands GnnVN, GnnSN, and GnnHN also control the visibility of Graphic Field nn, but without
updating the output and are recommended when the visibility of more than one field is to be changed at the
same time. The GU command can be sent to update the output after all visibility changes have been made.
The GnnHdddd command will turn off the visibility of text field nn after approximately dddd frames of video
have been output. When the GnnH is used with a delay, the overlay is automatically updated after the delay.
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 29 of 103
4.8.1.9.5 UPDATE GRAPHIC OVERLAY
The GU command updates the video output of the Overlay by rendering all fields to the spare buffer and
exchanging the active and spare buffers.
After sending a sequence of commands that change the parameters of fields, send the GU command to
make the changes visible.
4.8.1.9.6 COORDINATE SYSTEM AND FIELD POSITION
Each Graphic Field has two position coordinates referred to as Coordinate A and Coordinate B. One or both
of these coordinates may be used depending on the Graphic Field Type.
The coordinate system designates x=0000 and y=0000 as the top-left corner of the overlay for all video
formats. This is the default position for all fields.
The maximum value for the x and y coordinates is located at the bottom-right corner of the frame. For
1080p, 1080i, and 1080PsF formats the bottom-right corner is at coordinates x=1919, y=1079. For 720p
formats the bottom-right corner is located at x=1279, y=719. For NTSC format the coordinates are x=719,
y=485, and for PAL format x=719 and y=575.
NOTE: Some monitors will not display the entire video frame, particularly when operating in NTSC or PAL
modes. Graphic Fields placed close to the edges of the overlay may not be visible on some monitors.
NOTE: If the Overlay has been re-sized, the coordinate range may be smaller than the defaults for each
video mode listed above.
Any Field or portion of a Field that extends beyond the edges of the Overlay will not be visible.
The command set provides different options for setting the coordinates of a Graphic Field. The commands
GnnXxxxx, and GnnYyyyy set the x and y position for Coordinate A individually. The commands
GnnPAXxxxx and GnnPAYyyyy perform the same functions, but this form of the command can also set
Coordinate B, for example GnnPBXxxxx or GnnPBYyyyy.
If it also possible to set both x and y in a single command for Coordinate A or Coordinate B with the
commands GnnPAxxxx,yyyy and GnnPBxxxx,yyyy respectively. For all Graphic Field position commands,
the parameters xxxx and yyyy can be from 1 to 4 digits in length and may optionally be prefixed with zeros.
For example, sending G4X0200 and G4Y0400 sets the field position to (200, 400).
Changing the text position does not automatically update the video output.

DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 30 of 103
4.8.1.9.7 LINE COLOR AND TRANSPARENCY
Each Graphic Field has a Line Color specified by Red, Green, and Blue Components in the range from 0 to
255. The Line Color is used for solid rectangles, for the outline of open rectangles, for corner markers, target
markers, and the foreground of text.
The colors are entered as three Serial Commands by sending a Red, Green and Blue Serial Command. For
example: sending G1R220, G1G025 and G1B250 sets Text Field 1 to purple.
The default color is white (R255, G255, and B255). Changing the text color does not automatically update
the video output.
The Line Color has a transparency property that can be controlled using the G1Aaaa command to set the
alpha value for mixing with underlying layers. Setting the alpha value to 0 sets the Line Color to be fully
visible and no content on lower video layers will be visible through the Line Color. An alpha of 255 sets the
Line Color fully transparent. At this setting the color will be completely invisible.
For example: sending G1A192 makes Field 1 approximately 75% transparent. Changing the text
transparency does not automatically update the video output.
4.8.1.9.8 BACKGROUND COLOR AND TRANSPARENCY
Each Field has a Background Color that is used for the background of Text Fields and the fill color of
rectangles. Background Color is set in the same way as Line Color, except the commands used as
GnnBRrrr, GnnBGggg, GnnBBbbb, and GnnBAaaa.
The following example commands set the Background Color of Graphic Field 1 to yellow with partial (50%)
visibility: G1BR255, G1BG255, G1BB0, and G1BA128.
The Background Color will only affect those field types that make use of the Background Color.
Figure 12: Sample of transparent text and background
NOTES: When the text is partially transparent, its apparent color will be determined by the text color,
the background color and the visibilities of the text and background.
When a text background is displayed, the total number of color / transparency combinations is limited. Small
changes in the color or transparency parameters of the text or background may not change the appearance

Notes:
Refer to Table 28: Extended ASCII Character Table for a list of characters that are mapped to codes
A0-FF.
Refer to Table 27: Windings Character Table for a list of characters and their codes.
Fonts are loaded into memory individually the first time a layer update is performed that requires them. The
requirement to load the font makes the first layer update significantly slower.
Selecting font 0 uses a default font that varies depending on the video output resolution. For NTSC, PAL and
720p, the default font is Font 1, and for 1080i and 1080p the default is Font 2. If the font has been set, it can
be restored to the default by selecting font 0. For example, the G2F0 command restores text field #2 to the
default font.
Changing the text font does not automatically update the video output. The Text Font selection has no effect
on Fields unless the field type is set to Text.

4.8.1.9.10 GRAPHIC FIELD TYPE
Each Graphic Field has a type that can be set by the GnnMm command. The following Field types are
supported:
1 – Text (default)
2 – Rectangle
3 – Corner Markers
4 – Target Marker
5 – Image
The parameters for the Graphic Fields have different functions depending on the type of field being used.
Each field type is described further below:
4.8.1.9.10.1 Text Fields – Field Type 1
Text Fields are used to display a string of ASCII characters. Up to 195 characters may be displayed in a
field. For a list available fonts refer to Table 9: Text and Symbol Fonts.
The ASCII text is set using the GnnT”Text” command where the characters to be displayed are enclosed in
the quotation marks. If a quotation mark is required in the test, it must be preceded by the backslash
character. For example to set the text string for Field 7 to display Model "DX-2200-TI" use the command
G07T"Model \"DX-2200-TI\"".
The color and transparency of the character can be configured using GnnRrrr, GnnGggg, GnnBbbb to set
the red, green and blue component of the character color and GnnAaaa to set the transparency. Similarly,
the background can be configured using GnnBRrrr, GnnBGggg, GnnBBbbb to set the color and GNBAaaa to
set the transparency. The parameters rrr, ggg, bbb, and aaa must be in the range 0 to 255. For
transparency, a value of 0 is fully visible and a value of 255 is fully transparent. The default text is white and
fully visible. The default background is blue and fully transparent.
Coordinate A of the Graphic Field is used to specify the position for the top-left corner of the Text.
Coordinate B is not used for Text Fields.

G4BA128 ' 50% background transparency
G4X730 ' start text at x=730
G4Y10 ' start text at y=10
G4S ' enable Field 4 and update layer
4.8.1.9.10.3 Rectangle Fields – Field Type 2
Rectangle Fields are used to display a rectangle that can be either open or filled. A rectangle can be used as
a vertical or horizontal line. The rectangle is drawn between Coordinate A and Coordinate B where
Coordinate A must be the top-left corner and Coordinate B must be the bottom-right corner of the rectangle.
No rectangle will be drawn if the coordinates are not specified in the correct order.
A rectangle may be drawn with either one or two regions depending on the parameters of the Graphic Field.
The Line region is located around the perimeter of the rectangle and is drawn with the line color (as specified
by the GnnRrrr, GnnGggg, GnnBbbb, and GnnAaaa commands). The Line region has a width in pixels that
is specified in the width parameters of the Graphic Field. The default line width is 1pixel. If the line width is
large, the entire interior of the rectangle may be part of the Line region. If the line width is narrow the interior
of the rectangle contains a Fill region.
The command GnnWwwww set the line width to the same value for both the vertical and horizontal lines,
and the command GnnWxxxx,yyyy sets the horizontal line widths (xxxx) and vertical widths (yyyy)
independently. When the Width parameter is set to 0 in the above commands, or when the Width is greater
than half the size of the rectangle, the entire rectangle is drawn with the line color. The line width can also be
set for each side of the rectangle individually. The commands GnnWLwwww, GnnWRwwww, GnnWTwwww,
and GnnWBwwww set the width of the left, right, top and bottom sides of the rectangle respectively. A
parameter value of zero has a different meaning for these commands than it does for the previous
commands. When used with these four commands, the width value zero 0 prevents that side of the
rectangle from being drawn.
The Fill color parameters are set by the GnnBRrrr, GnnBGggg, GnnBBbbb, and GnnBAaaa commands. By
default, the Fill region is the entire interior of the rectangle that is not drawn in the Line color, but it is also
possible to limit the fill to a specified width around the interior of the line. Each side of the rectangle has a fill
width associated with it. The command GnnFXwwww sets the Fill width in pixels inside the left and right
sides of the rectangle, and, GnnFYwwww sets the fill width inside the top and bottom sides of the rectangle.
The commands GnnFLwwww, GnnFRwwww, GnnFTwwww, and GnnFBwwww set the fill width for the left,
right, top, and bottom sides individually. Any pixel that is within the fill width for one or more sides of the
rectangle is part of the Fill region. The default fill width for the left side is 9999, causing the left side fill to
extend throughout the entire interior of any rectangle. The default fill width for the right, top and bottom sides
is 10 pixels.
When a fill region exists, it may either be drawn with the background color, or else the pixels can be left
undrawn. The command GnnBD0 prevents the fill from being drawn, and the command GnnBD1 draws the
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 35 of 103
fill. By default, the rectangle Fill is blue, fully transparent, and not drawn. Choosing not to draw the fill is
different than drawing a fully transparent fill:
Transparent fill overwrites any pixels on the same layer drawn from a previously rendered field, but not
drawing the fill leaves the previous pixels unchanged.
Drawing filled rectangles is slower than drawing unfilled rectangles.

G2BD1 ' draw the fill region
G2BR0;G2BG0;G2BB255 ' fill is blue
G2BA224 ' fill is 7/8 transparent
G2S ' enable display of field 2 and update
4.8.1.9.10.5 Corner Marker Fields – Field Type 3
Corner Marker Fields are used to indicate a region of interest in the video.
The Corner Markers are drawn outside the region specified by Coordinate A (top-left) and Coordinate B
(bottom-right).
The Width parameter of the Graphic Field sets the width in pixels of the lines that make up the corner
markers, and the Length parameter of the Graphic Field sets the distance in pixels that the lines extend from
the corner.
Corner Markers are drawn in the line color (as specified by the GnnRrrr, GnnGggg, GnnBbbb, and GnnAaaa
commands).
By default four corner markers are drawn. It is possible to suppress the corner markers individually using the
GnnKcs command. The letter s represents either 1 to suppress the corner marker, or 0 to enable it. The
letter c represents a letter that indicates which corner marker is being referenced as follows:
A = top-left
B = bottom-left
C = top-right
D = bottom-right
For example the command G1KB1 will suppress display of the bottom-left corner marker of Graphic Field 1.
NOTE: If the width of a Corner Marker is made too large relative to its length, the Corner Marker will appear
as a square.

4.8.1.9.10.6 Target Marker Fields – Field Type 4
The Target Marker Field displays a '+' marker at the position specified by coordinate A of the Graphic Field.
The Length parameter of the Graphic Field sets the length of the horizontal and vertical lines. Half the length
extends each direction from the center of the Target Marker and the length has a resolution of 2 pixels so
that the marker is always symmetrical.
The width parameter of the Graphic Field set the width of the lines that make up the Target Marker. The
width has a resolution of 2 pixels with half the width on each side of center.
4.8.1.9.10.6.1 Target Marker Field Display Example:
G3M4 ' target marker field type

G3L100 ' 100 pixel long lines
G3R255;G3G0;G3B0 ' red
G3A0 ' fully visible
G3S ' display and update
4.8.1.9.10.7 Image Fields – Field Type 5
An Image Field displays an image that has been uploaded to the DX-2200-TI-03. Image Fields can be used
to display a logo or other custom graphics. The DX-2200 Uploader software supplied with the product is
used to upload images and store them in flash memory. Refer to §5DX2200 Software Upload Utility DX2200 Software Upload Utility for information about uploading images.
The image is displayed at the position specified by coordinate A of the Graphic Field. Any part of the image
extending beyond the size of the overlay is not displayed.
Uploaded images may have transparency for some or all pixels in the image. Support for transparency
depends on the file format of the image. Images that do not include transparency are always uploaded with
all pixels fully visible. By default, images will be displayed with the transparency that was included in the
uploaded image. The GnnAaaa command can be used to make the image more transparent. It is not
possible to make an image less transparent than was defined in the original file.
When an image is fully transparent or partly transparent, the image frame background will be visible behind
the image. The background color is set by the GnnBRrrr, GnnBggg, GnnBBbbb commands, and the
background transparency is set by the GnnBAaaa command. When the image frame background has
transparency, lower layers in the video mix will be visible behind the image. The default background
transparency for a graphic field is 255 (fully transparent). The image frame background will not be visible
unless the default transparency is changed.
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 37 of 103
Images are specified by an ID number that is set when the image is uploaded to the product. If the
requested image is not found in memory, then the Graphic Field has no effect.
Images are loaded from flash into main memory the first time they are required for a layer update. The first
layer update using an image will be significantly slower than subsequent updates.
4.8.1.9.10.7.1 Image Field Display Example:
G5M5 ' field type = Image field
G5PA800,300 ' location (800,300)
G5I35 ' display the image with id=35
G5A0 ' display with the uploaded transparency
G5S ' display the field and update the overlay
4.8.1.9.10.8 Rectangle XYWH – Field Type 6
This rectangle field type is the same as field type 2 with the exception that it is specified by top/left corner
and width/height instead of top/left corner and bottom/right corner. In some applications it may be more
convenient or efficient to specify the rectangle with width and height.
The GnnPBxxxx,yyyy is used to specify the width and height of the rectangle. All other commands are the
same as for field type 2 rectangles.
4.8.1.9.10.8.1 Rectangle Field Display Example:
G6PA800,300 ' top left corner at 800, 300
G6PB200,400 ' width 200 pixels, height 400 pixels

GnnH
For the active graphics layer, hide (turn off) Graphic Field nn and update the layer to
make the change visible.
GnnHN
For the active graphics layer, disable the visibility setting for a Graphic Field without
updating the output. The Field remains visible until another command causes an
update of the output.
GnnHffff
For the active graphics layer, Hide (turn off) Field nn after a delay of approximately ffff
frames of video. ffff is a number between 1 and 4 digits in length. The layers is
automatically updated when the delay expires.
GnnBRrrr
For Graphic Field nn on the active graphics layer, set the value of the red component
of the background color to rrr, where rrr is a number between 1 and 3 digits in length
and in the range 0 to 255.
The background color is used for text background and for the fill region of a rectangle.
GnnBGggg
For Graphic Field nn on the active graphics layer, set the value of the green
component of the background color to ggg, where ggg is a number between 1 and 3
digits in length and in the range 0 to 255.
The background color is used for text background and for the fill region of a rectangle.
GnnBBbbb
For Graphic Field nn on the active graphics layer, set the value of the blue component
of the background color to bbb, where bbb is a number between 1 and 3 digits in
length and in the range 0 to 255.
The background color is used for text background and for the fill region of a rectangle.
GnnBAaaa
For Graphic Field nn on the active graphics layer, set the value of the transparency for
the background to aaa, where aaa is a number between 1 and 3 digits in length and in
the range 0 to 255.
aaa = 0 makes the background fully visible.
aaa = 255 makes the background fully transparent (invisible).
GnnBDm
For Graphic Field nn on the active layer, this command controls if the fill region of a
rectangle is drawn, or if the pixels are left unchanged when the field is set to Rectangle
mode.
m = 0 - Do not draw the rectangle fill region
m = 1 - Draw the rectangle fill region.
Choosing to draw the fill region takes additional time to render and will overwrite any

4.8.1.9.11 LOW LEVEL GRAPHIC COMMANDS
The Low Level Graphic Commands provide an additional level of control over switching between the active
and spare overlay buffers and in rendering Graphic Fields. In certain situations the use of these commands
can provide fast update rates for the Overlay.
The Graphics Overlays of the DX-2200-TI-03 use two memory frame buffers. One of these buffers is the
active buffer that provides a video output that is mixed on top of the input video and the other is the spare
buffer where the next image is rendered when the text overlay is updated. In normal operation of the text
overlay, updating the output video requires rendering all Text Fields to the spare buffer, then exchanging the
two buffers and clearing the new spare buffer to prepare for the next update.
The Low Level Commands provide additional control of the process for cases where:
1) The time when the text overlay update becomes visible must be controlled more accurately than is
possible with the standard text overlay commands.
2) Faster updates are required, especially in cases when 2 or more text fields displayed but not all fields
need to be changed.

Command
Code
Mode of Operation
Low Level Graphic Overlay Commands
GB
Renders the graphic fields of the active layer to the spare buffer, but the buffers are
not swapped. The video output does not change.
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 44 of 103
Command
Code
Mode of Operation
GW
Swap the active and spare buffers on the active graphics layer, and then clear the
new spare buffer. No fields are rendered and the spare buffer is displayed with its
existing content.
GS
Swap the active and spare buffers on the active graphics layer without rendering and
fields or clearing of any buffers
GC
For the active graphics layer, clear the spare buffer
GnU
GnnU
For the active graphics layer, render only the field number specified to the spare
buffer.
NOTE: When a configuration is saved to Flash, the current parameters of the Graphic Fields are saved and
will be rendered to the active buffer when the DX-2200-TI power up. If the Low Level Graphic Overlay
Commands have been used, the overlay may be in a state that is dependent on both the Graphic Field
settings and sequence of past commands. In that case the overlay will not appear the same when the fields
are rendered again at power up.
4.8.1.9.11.1 Application Example 1
Suppose that it’s necessary to update the Graphic Overlay at a specific time. If the G1T command has been
used to configure a Field to display text, then executing GU will not take immediate effect because the Fields
must be rendered to the spare buffer before the buffer is switched. The time required to render the Field
depends on the number of characters drawn and the font size. This causes a noticeable delay from the time
the command is sent to when the video is updated.
By using the Low Level Graphic Overlay Commands the overlay update can be controlled more accurately.
After setting the Text Field with the G1T command, execute GB to render the text to the spare buffer. This
must be done prior to the desired switching time so that there is time to render to the spare buffer. The spare
buffer now contains the updated output, but it not yet being displayed. When the update is to be displayed,
execute the GW command and the buffers will be switched at the end of the current frame to make the
update visible.
4.8.1.9.11.2 Application Example 2
Suppose that 5 text fields are being displayed on a layer and that one field needs to be updated regularly (in
the same screen location) while the others do not change. In this case it’s possible to use the Low Level
Graphic Overlay Commands to update only the one field that changes to avoid re-rendering the other four
fields that don’t need to change. This also avoids the time required to clear the spare buffer.
Configure all 5 fields as required and enable display of the fields, then update the overlay so they are visible.
Execute the GB command to render all the fields to the spare buffer. The GB command does not switch
buffers or clear the spare buffer. At this point, both overlay buffers will contain identical images. When the
SS command is executed the overlay can switch between the two buffers. Next, the content of one field can
be changed with the GnnT command, and GnnU can be used to render only that string to the spare buffer.
When SS is executed, the buffers will be switched and the update is displayed without need of rendering the
other strings that were not changed.
Note that this procedure never clears the spare buffer and so no pixels can be removed from the overlay
except by overwriting them with different text or blank spaces. If the length of the new string is shorter than
the previous string, spaces can be appended to overwrite the pixels of the previous string. When leaving this
mode of operation, the GC command should be executed to clear the spare buffer so that it’s in the state
expected by the other overlay commands.

4.8.1.10 Graphic Layer 1 Overlay SERIAL Commands
The Graphic Layer 1 Overlay Serial Commands are almost identical to the Graphic Overlay Serial
Commands except that they automatically refer to the fields on Graphics Layer 1. These commands provide
a convenient method of accessing the top layer without specifying the Active Layer, and also provide
compatibility with previous versions of the DX-2200 products. Each command begins with the letter 'S'
instead of the letter 'G'.
For example, the commands: GL1; G3T" DX-2200" select Graphics Layer 1 and set the text string for
Graphic Field 3. The command S3T" DX-2200" performs the same function without changing the Active
Layer.

4.8.1.11 Frame Counter Overlay SERIAL Commands
The DX-2200-TI has a Frame Counter that displays the frame number on Graphic Layer 1 of the output
video. The count of the Frame Counter is based on the number of video frames output from the unit.
4.8.1.11.1 FRAME COUNTER DISPLAY MODE
The main function of the Frame Counter is to display an automatically incrementing count on the video. The
frame counter can display a count that increments on each video frame, formatted as either an integer, or as
HH:MM:SS:FF where FF is the frame number. It can also display the time from a clock that is independent of
the video, formatted as HH:MM:SS with 0 to 3 decimal places for seconds. The DX-2200 does not have a
battery backed up real time clock; therefore the time and frame counts are lost when the unit is powered
down or reset. If the frame count needs to be set to real time, or some other specific starting value, then an
external controller must send a Serial Command to the DX-2200 after power up to set the count. The time
can also be obtained from a GPS receiver attached to the DB9 serial port.
The Frame Counter has 9 modes of operation that are selectable using the SFMn command (See Table 14).
4.8.1.11.1.1 Frame Counter Mode 0
Frame Counter Mode 0 turns off the frame count display. When the automatic counter is off, it is possible to
send ASCII text and display it on the video by Serial Command. This mode supports writing short custom
strings at a high frame rate. If the external controller can send commands synchronized with video frames, it
is possible to draw at frame rate.
4.8.1.11.1.2 Frame Counter More 1
Frame Counter Mode 1 is a counter formatted as ‘HH:MM:SS:FF’, where FF is the frame number. For frame
rates of 29.97 and 59.94 Hz, the frame counter implements drop frame timecode by default so that the frame
counter displayed as time (Mode 1) tracks with real time. It is possible to disable drop frame timecode using
the SCF0 command. For all other video frame rates, the counter counts from 00 to the number of frames per
second minus one.
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 53 of 103
4.8.1.11.1.3 Frame Counter Modes 2 – 4
Frame Counter Mode 2, 3, and 4 displays the frame count as a four digit ‘NNNN’, a six digit ‘NNNNNN’, or
an eight digit ‘NNNNNNNN’ number with leading zeroes. The count increments on every output frame and
will reset to 0 when all digits are ‘9’.
4.8.1.11.1.4 Frame Counter Modes 5 – 8
Frame Counter Mode 5, 6, 7, and 8 are the time clock modes and display a 24 hour clock in the format
HH:MM:SS, HH:MM:SS.S, HH:MM:SS.SS and HH:MM:SS.SSS respectively.
NOTE: The time shown in the time clock display was the time sampled from the clock at the time text was
being drawn into the frame buffer and does not accurately represent the time of an external event
such as start of frame entering or leaving the DX-2200.
4.8.1.11.2 FRAME COUNT VALUE
The Frame Count can be set to a specific value at any time using Serial Commands.
The current frame count for Mode 1 can be set using the SFT:HH:MM:SS command. The current frame
count value used in Modes 2, 3 and 4 can be set by the SFNnnnn command. For the time clock modes, use
the command SFR:HH:MM:SS.SSS to set the time.
The three count values are independent of each other. All counters start at zero when the DX-2200 is
powered on or reset. The frame counts for modes 1 to 4 continue to be updated when the counter is not
displayed, but will pause when the video mode is switching and will lose sync with real time. The time clock
modes (modes 5 to 8) are not affected by the video and will always continue to count.
4.8.1.11.3 FRAME COUNTER APPEARANCE
Commands are provided to configure the position, color, transparency and font of the Frame Counter.
The default text properties for the Frame Counter are:
Foreground: Red = 255, Green = 255, Blue = 255, Transparency = 000
Background: Red = 000, Green = 000, Blue = 255, Transparency = 255
Position: X = 0, Y = 0
The syntax for the commands (see Table 14) that configure the appearance of the Frame Counter is similar
to those used by the Text Overlay Commands. Many of the commands include a Field number (nn). The
Field number may be either one or two digits, for example 01 or 1. Only field number 1 is supported by the
Frame Counter. All other values reserved for future use.
The Field numbers used by the Frame Counter commands are independent of those used by the Text
Overlay. This means that Text Overlay Field 1 can still be used normally when the Frame Counter is
operating.
The fonts used by the Frame Counter are different than those used in the Text Overlay. All Frame Counter
fonts are fixed width and hard edge. The available font and size options are listed in the command table (see
Table 14). Setting the font to 000 selects the default font which is dependent on the video mode. To ensure
the frame counter is drawn at the video rate, it is recommended not to use a font larger than the default font.
When the appearance of the frame counter is changed while the counter is visible, a frame will be generated
that has no frame count displayed while the parameters are being changed. Unlike the Text Overlay
Commands, the Frame Counter Commands take effect immediately.
NOTE: The blending of transparent text and text background differs between the Frame Counter and the
Text Overlay Fields. When the same parameters are used, the appearance may not match. For Text
Overlay Fields, partly transparent text blends with the text background color and if the background is
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 54 of 103
not fully visible, it also blends with the underlying image. For the Frame Counter, partly transparent
text does not blend with the frame counter background color.
4.8.1.11.4 MANUAL MODE
When the Frame Counter mode is set to 0 the automatic frame count display is turned off. In this case, an
ASCII string can be assigned to the Frame Counter Field using the SF01T command. The text can then be
drawn using the SFnnD command, or cleared using the SDnnH command. These commands render the text
to the active frame buffer instead of the spare buffer. In some applications it is possible to display a short
text string at higher speed using this mode than would be possible with the Text Overlay Commands.
The Frame Counter and the Text Overlay use the same active and spare frame buffers. If Text Overlay
Commands cause the spare and active buffers to switch, any text that was drawn into the active buffer with
the SFnnD command will no longer be visible. To display the text again, the ’SF1D’ must be used to redraw
the text in the new active buffer.
Notes: If the configuration is saved to flash, any text that has been by displayed using the Frame Counter in
Manual mode will not be restored when the unit powers up. Only text fields displayed using the Text Overlay
Commands will be restored.
After receiving the SFnnD, the Frame Counter will render text beginning after the frame buffer has
completed output of the video lines where the text will be located. If other commands are received prior to
rendering that change the text parameters or Frame Counter mode, the text will be rendered with the new
parameters or rendering may be cancelled by the new commands. Control software that sends commands
to the unit should include appropriate delays after sending the SF1D command to allow drawing to complete
before changing the Frame Counter parameters.

xxx= 0 selects the recommended default font.
xxx= 1 selects a 26 pixel font recommended for NTSC / PAL / 720p
xxx= 2 selects a 40 pixel font recommended for 1080i / 1080p
Note: Using the Frame Counter with a larger font than recommended may result
in slower updates and/or video frames with partially drawn count values.
SFm
Update mode. The Text Overlay and Frame Counter use the same video frame
memory. This command affects the update sequence when the Text Overlay
performs a buffer swap.
SF0: The Text Overlay swaps buffers immediately when it has completed
rendering text or is commanded to so. This mode provides fast response to the
Low Level Text Overlay buffer swap commands, but will often result is a frame
without the frame count displayed after the buffer switch.
SF1: The Text Overlay buffer swap is delayed while the frame count is drawn
into the new buffer before the buffers are switched. This avoids a frame without
the frame the frame counter display, but delays the buffer switch. This is the
factory default setting.
SFC1
Enable drop frame timecode for 29.97 and 59.94 frames per second modes. Drop
frame timecode is enabled by default.
SFC0
Disable drop frame counting for 29.97 and 59.94 frames per second modes.

4.8.1.12 Layer Control SERIAL Commands
The Layer Control SERIAL Commands allow layers to be updated, reduced in size, and moved. These
commands also duplicate some of the capabilities provided in the Text Overlay and Graphics Overlay
commands.
These commands include one or more layer numbers that are represented by 'nnn' in the command
descriptions. It is possible to specify a single layer, two layers, or three layers by combining layer numbers in
the command.
The layers are:
0 – Apply the command to all layers
1 – Graphics Layer 1
2 – Graphics Layer 2
3 – Graphics Layer 3
For example the LnnnU command updates layers:
L1U – Update layer 1
L12U – Update Layers 1 and 2
L123U – Update all Layers (1, 2 and 3)
L0U – Update all Layers (1, 2 and 3)
NOTE: When specifying layers, do not specify the same layer number more than once, and do not combine
'0' with any other layer number.
4.8.1.12.1 LOW LEVEL BUFFER CONTROL
The Layer Control Serial Commands can be used to access the same Low Level Overlay Functions that are
provided in the Text Overlay and Graphic Overlay Commands. In the case of the Graphic Overlay
Commands, it may be more convenient to use these commands because the layer number is included in the
command as a parameter to allow the command to be executed without need of changing the active
graphics layer.
The Low Level Buffer Control Commands are LnnnB, LnnnW, LnnnC, and LnnnS. When nnn is 1, these
commands are equivalent to the SW, SW, SC, and SS commands.
When n is 2 or 3, the commands are equivalent to the GB, GW, GC, and GS commands with the Active
Layer set to n.
4.8.1.12.2 VISIBILITY OF LAYERS
Individual layers can be enabled and disabled at the mixer. This provides a high speed method of turning a
layer on and off because the individual fields don’t need to be rendered.
The LnnnD command disables the visibility of a layer, and the LnnnE command enables visibility. The LnnnT
command toggles visibility on and off.
These visibility commands act as a master control to enable or disable the entire layer. The visibility settings
of the individual Fields on the layer are not changed by these commands. By default, all layers are enabled.
NOTE: If these commands are used to disable a layer, then the visibility commands for the individual Fields
on that layer cannot make them visible again. Only the LnE command or resetting the layer to
defaults can make them visible
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 59 of 103
4.8.1.12.3 ENABLING AND DISABLING LAYERS
If one or more layers are not required in an application, they can be disabled using the LnnnH command.
Layers that have been disabled can be re-enabled using the LnnnA command. In some circumstances,
disabling layers that are not used can improve update performance on the remaining layers.
These commands are relatively slow and may disturb the output video. They are recommended for use
during initial setup or at times when clean video output is not required.
4.8.1.12.4 RE-SIZING OVERLAYS
By default, all overlay layers are the same size as the video output of the DX-2200-TI. The LnnnKxxxx,yyyy
command sets a preferred size for the overlay. If the preferred size is smaller than the video size, the
overlay is reduced in size to match the preferred size. The overlay will never be larger than the output video
size.
When the overlay size is changed, the layer will be disabled momentarily and both the active and spare
frame buffers will be cleared. To see the content of the overlay after a size change the layer must be
updated, for example using the LnU command.
Setting xxxx and/or yyyy to 0 restores the default overlay size. It is not possible to set the overlay width or
height smaller than 16 pixels. For any of the interlaced video modes, the height of the overlay must be an
even number of pixels and will be automatically rounded up if necessary.
4.8.1.12.5 MOVING AN OVERLAY
When an Overlay has been reduced in size, (via the LnnnKxxxx,yyyy command) it is then possible to change
the x, y position of the overlay item within the boundaries of the output video. This process can then be used
for moving/panning an OSD target marker around the displayed video.
The LnnnPxxxx,yyyy sets the x and y position of the overlay. The overlay must always fit completely within
the boundaries of the output video. It is not possible to have an overlay partially off screen. This is the
reason that the overlay must be reduced in size before the position can be changed. It is also possible to
change only the x position using the LnnnPXxxxx command, or only the y position using the LnnnPYyyyy
command.
By default, the overlay position coordinates refer to where the top-left corner of the overlay is located in the
output video. The reference point can be changed to the center of the overlay instead of the top left corner
using the LnnnPM2 command.
Moving the overlay is very fast because it does not require rendering any Fields or switching the overlay
buffers. The overlay item can be repositioned at the video frame rate by sending Serial Commands at an
appropriate interval.

4.8.1.13 User Interface Commands
The user interface commands control the behavior of the DX-2200-TI and allow reconfiguration of the
functions performed by the DIP switch and toggle switch to customize the product for specific applications.
Configuration of the switches consists of two steps. The switch(s) to be configured are assigned to a user
interface function, and the user interface function is programmed to perform the required operations.
The DX-2200-TI has 4 DIP switches and one momentary contact toggle switch that toggles both left and
right. Different commands are used to assign the DIP and toggle switches.
4.8.1.13.1 DIP SWITCH ASSIGNMENTS
DIP Switch Assignments DIP switches are assigned to user interface functions using the ‘US’ commands.
An assignment command example is US1:01. This command will assign DIP Switch #1 to control user
interface function 01.
One or more DIP Switches can be assigned to the same user interface function. The number of switches
assigned determines how many different operations can be selected from the user interface function. When
one switch is assigned, two operations are available. Two switches allow four operations, three switches
allow eight operations and four switches allow the selection of 16 operations.
The factory default settings for the Toggle Switch are listed in Table 23: Operation of 2-Position Momentary
Toggle Switch and for the DIP Switch, Table 24: Operation of the 4-Position DIP Switch.
4.8.1.13.2 TOGGLE SWITCH ASSIGNMENTS
Toggle switch supports two functions: a toggle right or a toggle left function which are assigned using the UR
and UL commands respectively. The assignments can apply either to all modes of operation, or to one
specific mode. For example command: UR:03 will set toggling the Toggle Switch to the right to control user
interface function 03.
4.8.1.13.3 USER INTERFACE FUNCTION CONFIGURATION
The user interface functions are software components that have a selection input that is controlled by the
physical Switches that are assigned to it. For each value of the selection input, a different Serial Command
string can be assigned.
The DX-2200-TI has 20 user interface functions numbered 01 through 20. Each user interface function
supports up to 16 selections that are numbered 00 to 15. In the factory default configuration, all user
interface functions are unused and have no commands assigned to them.
The switches that control a user interface function can be either one or more DIP Switches, or a Toggle
Switch.
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 62 of 103
If DIP Switches have been assigned, then the value set on the Switches determines the selection. Each
Switch that has been assigned becomes one bit of the selection value, with the least significant bit being the
Switch with the lowest number (as marked on the DIP switch component). When a Switch is OFF, the bit
value is 0. When the Switch is on, the bit value is 1.
If a Toggle Switch has been assigned, then the Switch increments the selection each time it is toggled, until
a selection is found with no command assigned, or the maximum number of selections has been reached.
This indicates the end of the Toggle Switch function loop and the selection is reset to 0.
4.8.1.13.3.1 User Interface Commands
The UF commands are used to assign commands to the user interface functions. For example, the
command UF07,00:"S1V" assigns user interface function 07 selection number 00 to perform the command
S1V (toggle the visibility of Text Field 1). Any previous command assignment for this user interface function
and selection is erased by this command.
The command string that is being assigned is always enclosed with quotation marks. More than one
command can be assigned in the above command using a semicolon delimiter. For example
UF07,00:"S1V;S2V" will toggle the visibility of Text Field 1 and 2.
Another version of the UF command supports appending additional commands to a selection that already
has a command assigned. The command UF07:00+"S3V", executed after the previous example, adds the
command S3V to the previous commands.
Executing UF07,00:"" clears any command that was previously assigned to Selection 00 of user function 07.
When executing the UF commands, the command response (either ‘+’ or ‘-‘) indicates only that the syntax of
the UF command was accepted. It does not indicate the command string being assigned to the user
interface function is correct. Commands can be tested by executing them prior to assigning them to user
interface functions.
4.8.1.13.4 RESETTING TO FACTORY DEFAULT CONFIGURATION
The DX-2200-TI provides commands to clear the user functions and restore the default switch settings. All
selections of a user functions can be cleared using the UFnnC command where nn is the user function
number. All user functions can be cleared with the UFC command. The UR command restores the default
DIP and Toggle switch settings, but does not clear any user interface functions that the user has configured.
4.8.1.13.5 RECOMMENDATIONS FOR CONFIGURATION
Assign either one set of DIP switches, or one toggle switch to a user interface function. Assigning more than
one toggle switch, or both DIP and toggle switches to the same function will usually have undesirable
results.
Don’t assign Toggle Commands to DIP switches. For example, don’t assign ‘S1V’ to a DIP switch. Use ‘S1S’
and ‘S1H’ instead to show or hide a text field.

4.8.1.14 GPS Receiver Support
The DX-2200-TI can receive NMEA 0183 data sentences from an external GPS receiver attached to the
DB9 Serial Port. Data items from the GPS are stored in dedicated data fields in the product. By sending
commands to the DX-2200, it can be configured to use contents of selected data fields to set the text string
for specified Graphic Fields. The usual Graphic Field commands for visibility, font, color, position, etc.
determine how the data is displayed on the overlay. This allows the DX-2200 to overlay information such as
date, time, and position.
The text content of the Graphic Fields are automatically updated each time new data is received from the
GPS. After the DX-2200 has been configured, it can continue to operate and update the overlay data without
additional commands being sent to the control port.
Additionally, the time received from the GPS can be used to set the frame counter time clock to overlay a
higher resolution time display.
The DX-2200 is not compatible with NMEA 2000 devices or USB GPS receivers.
NOTE: GPS receiver support is not available for older DX-2200 products with Rev C or earlier board
revisions.
4.8.1.14.1 CONNECTION OF THE GPS RECEIVER
The DB9 connector on the DX-2200 has a custom configuration with two independent serial ports. The first
port, placed at the standard pin locations (pins 2 & 3) is the Control Port of the DX-2200. The second port,
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 65 of 103
placed at pins 7 & 8 is the GPS port. Refer to Table 17: DB9 Serial Y Splitter Cable Pin Connections and
Table 29: RS-232 Serial Port DB9 Pin Assignments for the pinout of the DB9 connector.
The DB9 Serial Y Splitter Cable, part number W6001, is available to attach to the DX-2200 DB9 connector
and provide two separate DB9 (female) sockets with one port on each connector. This cable may provide a
more convenient connection of the Control Port device and also the GPS to the DX-2200. The cable is not
supplied standard with the DX-2200. It must be ordered separately.
Figure 21: DB9 Serial Y Splitter Cable (Part # W6001)
GPS receivers will typically not have the required DB9 connector attached to the data cable and it will be
necessary to install the connector. The wiring of the GPS receiver to the DX-2200 will depend on the model
of GPS receiver that is used. Refer to the GPS receiver documentation for details.

An example connection is shown in Figure 22 for the Garmin GPS18x LVC Receiver. The example uses the
COM Port DB9 Serial Y Splitter cable. Note that if the splitter cable is not used and the GPS receiver is
wired directly to the DB9 on the DX-2200 instead, different pin numbers must be used. Instead of wiring the
green and white wires to pins 2 & 3, use pins 8 & 7. (Refer to Table 29: RS-232 Serial Port DB9 Pin
Assignments.)
The DX-2200 does not provide power for the GPS, therefore an external power source or battery operated
GPS will be required.

4.8.1.14.2 GPS DATA CAPTURE
The DX-2200 will capture data from the following NMEA 0183 sentences: $GPGGA, $GPRMC, $GPGLL,
$PGRMF, $GPVTG, $GPGSA, GPGSV, $PGRMV, $PGRME, and from Garmin proprietary sentences
$PGRMT, and $PGMID.
Table 18 lists the data fields that are captured by the DX-2200 and the NMEA 0183 sentences that provide
the data. If the GPS has not been configured to output one or more of the sentences for a data field, then
that field will contain an empty string. Refer to the instruction manual of your GPS to determine how to
configure it to provide the required sentences.
Refer to the NMEA 0183 standards or your GPS instruction manual for more information about the data

4.8.1.14.3 SELECTION OF DATA FIELDS – THE ‘CC’ COMMAND
The ‘CC’ command is used to select a GPS data field and copy it to a Graphic Field for display on the
overlay. The data supplied by the GPS is often not formatted appropriately for display. The CC command
provides formatting options for specific types of data to convert them into other formats. For example latitude
may be provided as “4255.1977” by the GPS. The CC command has an option to convert it to “42° 55.1977’”
for display.
The format of the CC command is:
CCnnFmmMff[Aaaa][Bbbb]
The lower case items represent numbers and the items in brackets are optional or dependent on the
formatting method selected. In all cases, nn represents the Graphic Field number that text will be stored in,
mm is the GPS data field number to read, and ff is the formatting mode.
The following CC command example sets the text content for Graphic Field 01 and specifies that it should
be set using GPS data field 3 (Latitude). Format method 1 is used in this example, which is a simple copy of
the GPS data directly to the Graphic Field.
CC01F3M1
The available formatting options are described in Table 19.
Table 19: Data Formatting for the ‘CC’ Command
Format
Type
Description
1
Copy the GPS Data to the Graphic Field without any formatting changes. No optional
parameters are available for this format method.
This format mode can be used for any data field.
The command syntax is CCnnFmmM1 where, nn is the Graphic Field to set and mm is the GPS
data field to copy
2
Copy with leading zero suppression. If the data field contains leading zeros, they are removed
when the data is copied to the Graphic Field.
The command accepts optional parameter A1 that causes the leading zeros to be replaced with
spaces instead of being removed.
This format mode is intended for use with GPS data fields containing a number
The command syntax is CCnnFmmM1, or CCnnFmmM1A1 where,
nn is the Graphic Field to set
mm is the GPS data field to copy

Format
Type
Description
3
Format time fields. The data field should be time in the format HHMMSS[.s...s]. Using this
format option on other types of data will produce incorrect results.
The format mode can be used without optional parameters to display the time HH:MM:SS[.s...s]
with the same number of decimal places as the GPS provided.
The command supports optional parameter A to specify a number of decimal places between 0
and 3 to display for seconds. If the GPS data field does not contain enough decimal places,
zeros will be added. The command syntax is CCmmFnnM3Ad, where d is the number of
decimal places to display for seconds.
For example CC01F01M3A1 copies time to Graphic Field 01 with 1 decimal place for seconds.
The command supports optional parameter B to specify conversion to 12 hour clock format.
The syntax is CCmmFnnM3Bb.
Parameter b specifies the 12 hour format:
0 - 12 hour with no am / pm indication
1 - 12 hour clock and append “ am” or “ pm”
2 - 12 hour clock and append “ a.m.” or “ p.m.”
3 - 12 hour clock and append “a” or “p”
For example CC01F01M3B2 copies the time to Graphic Field 1 with 1 decimal place and
converts the time to 12 hour format with “ a.m.” or “ p.m.” appended.
Note: Both the A and B parameters can be combined in the same command.
4
Format time fields for HH:MM display (no seconds). The data field should be in the format
HHMMSS[.s…s]. Using this format option on other types of data will produce incorrect results.
The command syntax is CCmmFnnM4[Bd], where d specified 12 hour clock format as
described in format mode 3 above. Optional parameter A cannot be used in this format mode.
For example CC01F01M4 formats the time as HH:MM, and the command CC01F01M4B0
formats the time as HH:MM with the time converted to 12 hour format and no am / pm
indication.
5
Copy a substring from the GPS data field to the Graphic Field.
The syntax is CCmmFnnM5AfffBnnn where both parameters A and B are mandatory and fff
specifies an offset into the GPS data field to start the copy, and nnn specifies a maximum
number of characters to copy.
For example, the command CC01F01M5A0B2 copies the two digit hours from the UTC time of
position fix data and places them in Graphic Field 01.
Note: This command is not useful for GPS data fields that have variable format.
6
Format the GPS data for degrees and minutes display, for example 081° 15.9300’. This format
mode should be used on GPS data fields that have a format of [d]ddmm.mm[m..m]
The syntax is CCmmFnnM6[Afff][Bddd][Cc] where:
• Optional parameter A specifies an additional field number containing a hemisphere
indicator such as ‘N’, ‘S’, ‘W’, or ‘E’. The first character of the specified field is copied
into the Graphic Field following the degrees and minutes.
• Optional parameter B specifies a maximum number of decimal places that should be
shown for minutes. If the GPS data does not include the requested number of decimal
places, they will not be displayed.
• Optional parameter C specified to suppress leading zeros of the degrees field. C0
drops the leading zeros. C1 converts leading zeros to spaces.
For example, to set Graphic Field 01 to contain Latitude with the hemisphere indicator, use the
command CC01F03M6A4

Format
Type
Description
7
Format the GPS data as degrees by displaying the ° symbol after the number. This format type
should be used for fields containing a number.
The syntax is CCmmFnnM7[Aa], where optional parameter A0 causes leading zeroes to be
dropped and parameter A1 causes leading zeros to be converted to spaces.
8
Format the GPS data as a date in the format DD/MM/YY
This format type should be used for fields containing a 6 digit data such as Field 02, “UTC Data
of Position Fix”
The command syntax is CC01FnnM8[A1], where the optional A1 parameter causes the year to
be displayed as 20yy.
For example use the command CC01F02M8 to copy the GPS date to Graphic Field 01
4.8.1.14.4 GPS INTERFACE SETUP COMMANDS
The GPS data setup commands control the operation of the GPS data capture function. By default, the GPS
port is set to 4800 baud and the GPS data capture is not enabled.
To enable capture of data, use the CSE command. If the GPS is not set for 4800 baud, then use the
CBSnnnn command to set a new baud rate, for example CBS19200 to set the baud rate to 19200.

/ linefeed. For example CTA"$PGRMO,PGRMC,1”
CTB”msg”
Transmit a message to the GPS. Only the characters in msg are transmitted. The
checksum, carriage return and line feed must be included in the string.
For example CTB"$PGRMO,GPGSV,0*22\r\n"
CSSE
After video starts (at startup or after a mode change) use the GPS time to set the Frame
Counter Time Clock.
CSSD
Disable setting the Frame Counter Time Clock from the GPS time at startup and when
video mode changes.
CSAE
When setting the Frame Counter Time Clock, also set the time format frame counter.
CSAD
When setting the Frame Counter Time Clock, no not set the time format frame counter.
CSF
Set a time offset.
GPS data field 59 contains a copy of the time from field 01 “UTC Time of Position Fix”,
that has been adjusted by the correction specified in this command.
The adjustment can be used to shift the clock for local time. It can also be used to
correct for delays between the GPS internal time reference and the GPS transmitting its
time output sentence. The DX-2200 does not have an input for the reference pulse that
is available from some GPS receivers, and uses the start of the NMEA 0183 sentence
containing the time as the reference. The GPS may have up to hundreds of milliseconds
of delay in sending output messages.
When the GPS is used to set the Frame Counter time clock, or the time formatted frame
counter, the adjusted time in GPS data field 59 is used. Therefore any clock adjustment
set with this command also applies to those displays.
The default argument of the CSF command is specified in milliseconds, for example
DX-2200 – SD/HD-SDI Text & Graphics Inserter – User Manual
Page 74 of 103
Command
Description
CSF-400 to adjust the time in GPS field 59 by -400 milliseconds
The CFS command also accepts arguments followed by S, M, and H to set adjustments
in units or seconds, minutes, or hours. Decimal points are not permitted, but offsets in
hours, minutes, seconds and milliseconds can be combined in the command. Each
adjustment can have a sign ‘+’ or ‘-‘. If no sign is provided the adjustment is taken as
positive, but when the sign is provided, it is sticky and applies to all subsequent
arguments until a new sign is found.
For example:
• CSF-2h30m – specifies an offset of -2:30:00
• CSF-2h+30m – specifies an adjustment of -2 hours + 30 minutes for a total
adjustment of -1:30:00.
• CSF2h30m – species an adjustment of +2:30:00
• CSF5h400 – specifies an adjustment of 5:00:00.4 (five hours and 400
milliseconds).
The total adjustment allowed has a limit of 24 hours regardless of how it is specified.
Notes about time adjustment:
GPS data on the overlay is updated when data is received. If the adjusted time in field
59 is displayed on the overlay, and a correction of for example 400 milliseconds is used
with a GPS that updates once per second, the times on the overlay will be displayed as
03:31:20.4, 03:31:21.4, 03:31:22.4, etc. which may not be desirable. If a GPS with a
faster update rate and time resolution of 0.1 second were used instead, the output would
count as expected.
CSMn
Frame Counter synchronization mode.
After the frame counter time clock has been set, it runs from a crystal oscillator on the
DX-2200 and will gradually drift from real time. Synchronization modes provide a method
to keep the time clock synchronized with the GPS.
n = 0 - no synchronization. The frame counter time clock runs independently.
n = 1 - monitor GPS time and make micro-adjustments to the frame counter time clock to
track the GPS time. If the error is found to exceed the error threshold, the time clock is
re-set from the GPS time.
n = 2 – monitor and GPS time and re-set the time clock when the error exceeds the
threshold set by the CSR command.
CSRttt
Set the error threshold in milliseconds for performing a set of the frame counter time
clock. The default is 100 milliseconds. The frame counter time clock is compared to the
adjusted GPS time in GPS data field 59. If the error in the clock is found to be greater
than the threshold, the GPS time is used to set the clock.
CSS
Set the Frame Counter time clock when the next GPS time message is received. The
clock is set based on the adjusted time in GPS data field 59
4.8.1.14.4.1 GPS Data Display Example:
The following commands 7 data items at the top of the overlay and are intended for use with 720p video and
the Garmin GPS18xLVC receiver. To provide the necessary data for this example, the GPS should be
configured to output $GPGGA, $GPRMC, and $GPVTG sentences.

4.8.1.15 Configuration Flash Serial Commands
The DX-2200-TI uses Flash memory to retain user configuration information. The Flash is configured using
the commands shown in Table 21 below.
To save the current configuration, use the 'FW' command. This command saves the current operating
settings of the DX-2200 including the default resolution, and graphic field settings. The unit will restart with
the saved settings each time it powers up.
NOTES:
1) It is not necessary to erase the Flash before storing a new configuration. A write will automatically
erase the old configuration.
2) A saved configuration is only valid for the DX-2200 firmware version that saved it. If the DX-2200
firmware is updated, the saved configuration will be lost.
3) Baud rate cannot be saved in the configuration. The DX-2200 always starts at 115200 baud.
Table 21: Flash Serial Command Codes
Command
Code
Mode of Operation
Flash Write/Erase/Reset Commands
FW
Write the current configuration to the flash memory. The saved
configuration will be loaded whenever the DX-2200 starts.
FE
Erase the saved configuration from flash. The DX-2200 will use default
configuration after the next restart.
FR
Erase the saved configuration flash and reset the DX-2200 in default
factory configuration. Note that the FR command does not erase any
images that have been uploaded to the DX-2200.
FIC
Clear the uploaded images from memory. This command clears only the
copy of images stored in main memory. It does not erase images stored
in the flash. To erase the flash memory, first execute FIC and then FIW.
FIW
Write the image memory to flash. This command may take a few minutes
to complete.

4.8.1.16 Other Serial Command Codes
Other miscellaneous Serial Command codes are listed in Table 22 below and discussed in the following
sections.
4.8.1.16.1 SERIAL PORT RESET SERIAL COMMAND
Sending a Carriage Return or a Linefeed (CR or LF) ASCII code resets or clears the Serial Command buffer
on the DX-2200-TI.
Table 22: Other Serial Command Codes
Command
Code
Mode of Operation
IP Core Revision Code
RV
Polls the board for the product ID and IP Core revision
RSn
Report the input video resolution at input n where n = 1 for input 1 and n=2 for input
2. When these commands are received, the DX-2200 outputs a response message
in the format X<LF>+, where X is one of the following values:
X = 0: No video or unsupported mode
X = 1: 720p
X = 2: 1080p
X = 3: 1080i
X = 4: NTSC
X = 5: PAL
When this command reports a video resolution, it only indicates that the input video
is recognized by the DX-2200. It does not mean the input is compatible with the
current operating mode of the product, or that it is available for display. See also
the RIn commands.
RIn
Report input video resolution at input n where n = 1 for input 1 and n=2 for input 2.
When these commands are received, the DX-2200 outputs a response message in
the format X<LF>+, where X is one of the following values:
X = 0: No video or unsupported mode
X = 1: 720p
X = 2: 1080p
X = 3: 1080i
X = 4: NTSC
X = 5: PAL
The RI commands will return X=0 when the input video mode is not supported by
the product, or when the video is not valid for the current configuration. For
example if input 1 is 1080p video, and input 2 is 1080i, the RI2 command returns
return X=0. Even though 1080i is supported by the DX-2200, it cannot be used as
a PiP overlay when input 1 is a progressive video format. In this case, the return
value of 0 indicates the video cannot be displayed.
FS

4.8.2 MANUAL Mode of Operation
In the MANUAL mode, the operation of the DX-2200-TI is controlled by the momentary bi-directional Toggle
Switch and the DIP switches as described in Table 23 and Table 24 below. SERIAL Control is still available
when MANUAL mode has been enabled.
When MANUAL mode is enabled, some settings can be controlled by both the DIP switch and SERIAL
commands. In the case where a SERIAL command is used to change a setting that is also controlled from
the DIP switch, the setting of the switch will be overridden. Changing the position of the switch will return
control of the setting to the DIP switch.
The functions of the DIP and Toggle Switch are programmable by Serial Commands. The following section
describes the factory default configuration.
4.8.2.1 Toggle Switch
In the factory default configuration, the 2-position momentary Toggle Switch (labeled SW2) is used to switch
input and to select the operating mode from a variety enhanced video processing functions described in
Table 23 below.
Table 23: Operation of 2-Position Momentary Toggle Switch
Switch Movement
Mode of Operation
Toggle Left (TL)
Toggle Graphics Layer 1 On / Off.
This switch executes the L1T command to toggle the visibility
of the text layer.
Toggle Right (TR)
Toggle the Graphics Layers 2 and 3 On / Off.
This switch executes the L2T and L3T commands to toggle
the visibility of both layers.
4.8.2.2 Bypass Saved Configuration Using Toggle Switch
The DX-2200 normally loads the saved configuration at power up. If the saved configuration is corrupted
then it is possible the unit will not start. To recover from this situation, disconnect power from the unit, push
the Toggle Switch left (towards the power connector), and then re-connect power while continuing to hold
the switch for four seconds. The DX-2200 will start with the defaults instead of loading the saved
configuration.
Note that the saved configuration is not erased by this procedure and will load again the next time the
product is reset or powered up. To permanently clear the configuration, issue the FR command, or use the
FW command to write the current configuration to the flash.
4.8.2.3 DIP Switch Settings
For MANUAL mode, the DIP switch settings control the operation of the DX -2200-TI. The factory default
settings are summarized below:

By default, the settings of the DIP switch are read when the switch is changed and also at startup if
there is no saved configuration. When there is a saved configuration the switch is not read at startup
to avoid overriding the saved settings. Refer to the user interface commands for other DIP switch
options.

5 DX2200 Software Upload Utility
The DX2200 Software Uploader is a Java application supplied with the DX-2200-TI-03 that can be used to
update the product firmware, or to upload graphic images into the product for use as an Overlay.
5.1 Firmware Update Procedure
The firmware update procedure is documented in the DX-2200 Software Uploader User Manual available
for download from the Document Library in the Support area of our website at:
www.microtronix.com/SUPPORT/downloads.html
Contact support@microtronix.com for the latest release of the DX-2200 firmware and Software Uploader
utility.
NOTE: DX-2200-TI-03 Text Inserter product running firmware versions less than 1.10 cannot be upgraded
over RS232. It is recommended not to downgrade a unit to any version less than 1.10 because it will
lose the ability to update over RS232. For units that cannot be updated by RS-232, refer to Section
A.4.1 JTAG Firmware Upload Procedure or contact Microtronix sales about upgrading the unit.
5.2 Uploading Images
The DX-2200-TI-03 can store one or more images in memory. A stored image can be displayed on the
Overlay by configuring a Graphic Field to show that image.
A maximum of slightly less than 2 Mega Pixels can be stored in flash memory. The pixels can be used for a
single large image, or for many smaller images. For example, one full frame image for 1920x1080 video can
be stored, or up to 64 images at 240 by 135 pixels each.
When an image is uploaded, an identification number (ID) is assigned to the image. The ID is used to select
that image when it is to be displayed on the overlay. It is recommended to keep a record of the ID number
used when images are uploaded.
The DX2200 Software Uploader program can show a list of images that are stored in the memory with their
sizes and ID, and also reports how many pixels are available in flash memory. Individual images can be
deleted, or the entire memory can be cleared to remove all images.
The DX2200 Uploader software accepts image files in PNG and JPEG format. The PNG file format supports
Red, Green, and Blue channels, and also supports an optional transparency channel to set the visibility of
each pixel. The JPEG file format support Red, Green and Blue channels. The DX-2200-TI-03 accepts files
with or without the transparency channel. When a file without transparency is uploaded, all pixels are visible.
When the file includes a transparency channel, different parts of the image can have different visibility for
example to generate smooth edges, or to overlay images that are not rectangular.
WARNING: Most PNG files do not include a transparency channel. To generate a PNG file with
transparency an image editor such as Adobe Photoshop or Gimp can be used.
NOTE: The capability to store images permanently in flash memory requires a unit with 16 MB of serial flash
memory. These units are identified with PN: DX-2200-TI-03. Units shipped prior to April 2014 (PN:
DX-2200-TI-02) do not have the required flash memory and cannot permanently store images.
Images can still be uploaded to the unit, but are lost on reset or power-off.

6 Text Writing Performance Measurements
The text writing speed of the DX-2200-TI has been benchmarked at 1080p30 and 720p60 video resolutions
using a program on a PC to deliver text strings and commands to the SD/HD-SDI Text & Graphics Inserter
unit. The PC program uses Standard Graphic Overlay Control Commands (per commands of Table 12) and
also Low Level Overlay Control Commands (per commands of Table 13).
With the standard Graphic Overlay Commands, all of the video text is rendered (i.e. generated in the active
display buffer) when Fields are changed. However, with the Low Level Overlay Commands, the user
program first renders the static (i.e. non-changing) text to both the active and spare buffer and then updates
only the changing text string into the spare (background) buffer and then simply swaps the buffers (upon the
user Serial Command). To maximize the speed of text updates, text in the new background buffer is not
cleared after the swap and only changing Text Fields are rendered in the background buffer. The results of
the two methods are provided in the following sections.
6.1 Standard Text String Update Benchmark Measurements
In this test a number of characters were written through the Serial Port of the DX-2200-TI for OSD using
three font sizes: the F001 (small 26 pixel height), F002 (medium 40 pixel height) and F003 (large 78 pixel
height). A total of 20 of the characters were subsequently changed for each update. The time required to
update the output display was measured in frames of delay. The results are summarized below.
