Introduction
About the Digital XPoint Series Matrix Switchers
The Extron Digital XPoint Series Matrix Switchers are serial digital interface (SDI)
matrix switchers that distribute any SDI input to any combination of SDI outputs.
The matrix switchers can route multiple input/output configurations
simultaneously. Two matrix sizes are available:
• DXP 44 SDI (four inputs by four outputs)
• DXP 88 SDI (eight inputs by eight outputs)
The switchers conform to the SMPTE 259M specifications and route signals in all
composite (143 Mb/s and 177 Mb/s), component 4:2:2 (270 Mb/s), and widescreen
16:9 (360 Mb/s) SDI video standards. Each input signal is equalized: a 270 Mb/s
input signal is equalized for distances of 1000 feet (300 meters) on high quality
cable such as Extron RG6 BNC Series Super High Resolution coaxial cable. Each
input signal is buffered and looped through to allow it to be sent to other
equipment. Each output has dual buffered and equalized BNC outputs (two
identical output signals per output) (figure 1-1).

Figure 1-1 — Typical Digital XPoint Switcher application
The switcher has an RS-232/422 port for local control. The switcher can be
controlled via the front panel or using the Extron Simple Instruction Set™ (SIS™)
and/or Extron’s Windows-based control program via the RS-232/422 link.
The Digital XPoint Series Matrix Switchers are housed in rack-mountable, 1U high,
17.5" (44.5 cm) wide metal enclosures. With the included mounting brackets, the
switchers can be rack mounted, mounted under a desk or table, or mounted against
a wall or the side of a desk. Each model has an internal 100VAC to 240VAC, 50/60
Hz, 40 watt power supply that provides worldwide power compatibility.
Digital XPoint Matrix Switchers • Introduction1-2
Features
Inputs — 4 or 8 SDI video inputs on BNC connectors and 4 or 8 equalized and
buffered loop-throughs on BNC connectors
Outputs — 4 or 8 SDI video outputs with two buffered and equalized outputs each
on BNC connectors
Serial digital data rates from 143 Mb/s to 360 Mb/s — Capable of switching signals
in 4fsc (composite) or 4:2:2 (component) serial digital video transmission
standards

compliance
Automatic input cable equalization — Each input signal is equalized: a 270 Mb/s
input signal is equalized for distances of 1000 feet (305 meters) on high
quality cable such as Extron SuperFlex SHR Super High Resolution coaxial
cable.
Automatic rate selection — The Digital XPoint automatically accepts four SMPTE
data rates, including 143 Mb/s, 177 Mb/s, 270 Mb/s, and 360 Mb/s. The
auto rate selection is ideal for multi-rate serial data protocols because the
switcher automatically detects and locks onto the incoming data signal.
Output data muting when the input source is lost — An internal muting function
forces the serial data outputs to a static state when input data is not present
or not locked.
16 global memory presets — 16 memory presets are a time-saving feature that lets
you set up and store input/output configurations in advance and then recall
those configurations with a few simple steps when needed.
Operational flexibility — Operations such as input/output selection and setting of
presets can be performed on the front panel or over the RS-232/RS-422 link.
The RS-232/RS-422 link allows remote control via a PC or control system.
•Front Panel Controller — The Digital XPoint Series front panel controller
supports touch-of-a-button input and output selection and preset creation
and selection. The front panel features large, positive touch, illuminated
pushbuttons that can be labeled with text or graphics.
•Windows-based control program — Extron’s Windows-based control
program provides a versatile range of operational options with its graphical
interface and drag-and-drop/point-and-click operation. The Windows-based
control program also has an emulation mode that lets you create a switcher
configuration file at the home office and then download it for use by the
switcher on site.
•Simple Instruction Set (SIS) — The remote control protocol uses Extron’s SIS
for easy programming and operation.
Input carrier detection — When input data is locked, the DXP indicates the
presence of a carrier source. This information is available via the
RS-232/RS-422 port and either the Windows-based control program or an SIS
command.
Remote control — The Digital XPoint switchers are remote controllable, using the
MKP 1000 master control keypad and any combination of MCP 1000 slave
control panels and/or MKP 1000 slave control keypads. The remote control
devices are easy to use and provide tactile buttons for quick selection. Each
MCP 1000 can be used for one-touch switching for a particular output and for
selecting global presets. Each MKP 1000 dedicated to an output can be used
to select a different input for that output or to select a preset.

Mounting the Switcher
The Digital XPoint Matrix Switcher comes with two sets of mounting brackets. One
set is for mounting the switcher under a table or against a wall, and the other set is
for rack mounting.
Table or wall mounting
The table/wall mounting brackets extend approximately 1/4” (6.4 mm) above the
top surface of the switcher enclosure. This design allows for an air space between
the enclosure and the surface to which it is mounted. Table or wall mount the
switcher as follows:
1.Attach the table/wall mounting brackets to the switcher with the eight

secure the switcher in place.
Rack mounting
UL requirements
The following Underwriters Laboratories (UL) requirements pertain to the
installation of the matrix switcher into a rack (figure 2-1).
1.Elevated operating ambient temperature — If installed in a closed or multi-
unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore, consider
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
2.Reduced air flow — Installation of the equipment in a rack should be such
that the amount of air flow required for safe operation of the equipment is not
compromised.
3.
Mechanical loading — Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.
4.Circuit overloading — Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits
might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when
addressing this concern.
5.Reliable earthing (grounding) — Reliable earthing of rack-mounted
equipment should be maintained. Particular attention should be given to
supply connections other than direct connections to the branch circuit (e.g.
use of power strips.

Figure 2-4 — RS-232/RS-422 port pin assignments
See chapter 4, “Programmer’s Guide”, for definitions of the SIS commands
and chapter 5, “Matrix Software”, to install and use the control software.
The Digital XPoint Series Matrix Switchers are factory configured for RS-232
control. To use the switcher under RS-422 control, an internal cable must be
moved. See chapter 6, “Maintenance and Modifications”, for the procedure for
swapping the serial ports.
If desired, connect an MCP 1000 remote control panel master unit to the
switcher’s RS-232/RS-422 connector. You can also connect an MKP 1000
remote keypad or MCP 1000 slave unit to the MCP 1000 master unit. Refer to
the MCP 1000 Remote Control Panel User’s Manual, part #68-456-01, and the
MKP 1000 User’s Manual, part #68-355-01, for details.
External sync connection
When switching between inputs, the resulting image change should be seamless, or
clean. The Digital XPoint Switchers can use an external signal to synchronize
switching during the vertical sync interval. Without the external sync locking
feature, switching between inputs can result in a brief rolling (sync loss) or a brief
change in the picture size.

Front Panel Controls and Indicators
All Digital XPoint controls and indicators are on the front panel (figure 3-1). The
large, illuminated push buttons can be labeled with text and/or graphics. The
buttons can be set to provide amber background illumination all the time or the
background illumination can be set to off. The buttons blink or are fully
illuminated (depending on the operation) when selected. The 8x2 character LCD
indicates the current I/O configuration, preset configurations, the input detection,
and the status of additional system features.
Figure 3-1 shows the DXP 88 SDI. The DXP 44 SDI is identical, with the
exception of fewer input and output buttons. The function of the DXP 44 SDI
is identical, with the exception of the preset number assignments.

The following terms apply to Extron matrix switchers, and are used throughout
this manual:
Tie — An input-to-output connection.
Set of ties — An input tied to two or more outputs. (An output can never be tied
to more than one input.)
Configuration — May consist of one tie or one or more sets of ties.
Current configuration — The configuration that is currently being used (also
called configuration 0)
Global memory preset — A configuration that has been stored. Up to 16 global
memory presets can be stored in memory. The input and output buttons
select the desired preset memory location to load or retrieve a preset. When
a preset is retrieved from memory, it becomes the current configuration.
One preset can be assigned to each input and output button. On the
DXP 44 SDI, presets 9 through 16 can only be stored and retrieved via the
RS-232/RS-422 link.
LCD display
Status display — The 8-column by 2-line Status LCD displays the I/O
1
configuration, preset configurations, and the status of additional system
features.
Input buttons and output buttons
Input 1 through 8 buttons — The input buttons have three independent
2
functions: to select an input, to select a preset, and to identify the selected
inputs. A more detailed explanation of these functions is included in “Front
Panel Operations”, beginning on page 3-3.

The translucent covers on the pushbuttons can be removed and replaced to insert
labels behind the covers.
Input and output labels can be created easily with Extron’s Button Label Generator
software, which ships with every Extron matrix switcher. Each input and output
can be labeled with names, alphanumeric characters, or even color bitmaps for easy
and intuitive input and output selection (figure 3-2). See chapter 5, “Matrix
Software”, for details on using the labeling software. See chapter 6, “Maintenance
and Modifications”, for blank labels and procedures for removing and replacing the
translucent covers.

Front Panel Operations
The following paragraphs detail the power-up process and provide sample
procedures for creating ties, sets of ties, and configurations; changing a
configuration; viewing ties, sets of ties, and configurations; saving a preset; and
recalling a preset.
Power
Power is automatically applied when the power cord is connected to an AC source.
When AC power is applied, the switcher performs a self-test that cycles the front
panel button indicators on and off from left to right lit green, right to left lit red,
and left to right lit amber. The self-test also displays the model name and the
firmware version in the LCD display. After approximately 2 seconds, the LCD
reverts to its default display, Extron DXP 88 (or Extron DXP 44) (figure 3-3). An
error-free power up self-test sequence leaves all of the button indicators off or
background illuminated and the LCD displaying the default display.

The current configuration and all presets are saved in non-volatile memory. When
power is applied, the last current configuration is retrieved. The previous presets
remain intact.
If an error occurs during the self-test, the switcher locks up and will not operate. If
your switcher locks up on power-up, call the Extron S
Hotline.
Switch modes
The Digital XPoint switchers have two switching modes:
•The enter switch mode, in which selected switch changes take effect only after
you press the Enter button.
•The quick switch mode, in which the changes take place on the fly, as you
select them, without the need to press the Enter button.
The current switch mode can be determined by pressing and releasing an output
button. In the enter switch mode, output buttons light or blink green when
selected. In the quick switch mode, the output buttons light red. After
approximately 10 seconds, the buttons return to either unlit or to background
illumination.
Toggle between the two modes as follows (figure 3-4):

1.Only one video input can be tied to an output, but multiple outputs can be
tied to a single input.
2.If a tie is made between an input and an output, and the selected output
was previously tied to another input, the older tie is broken in favor of the
newer tie.
3.To indicate current ties, the associated input button lights green (both
modes) and all the associated output buttons light green (enter switch
mode) or red (quick switch mode) when either an input or output button
is selected.
4.If an input with no tie is selected, only that input’s button lights green.
5.In enter switch mode, as each output is selected, the associated output
button blinks green to indicate a tentative tie. Buttons for output(s) that
were already tied to the input light green steadily. Outputs that are
already tied can be left on, along with new blinking selections, or toggled
off by pressing the associated output button.

The switcher’s rear panel RS-232/422 9-pin D female connector (figure 4-1) can be
connected to the RS-232 or RS-422 serial port output of a host device such as a
computer running the HyperTerminal utility, an RS-232 capable PDA, or a control
system. This connection makes software control of the switcher possible.

The protocol is as follows:
• 9600 baud• no parity
• 8-bit, 1 stop bit• no flow control
If your Digital XPoint Series switcher was previously set up for RS-232, and
your computer comm port uses RS-422, you must change the switcher cabling
to match the computer interface. See chapter 6, Maintenance andModifications, for the procedure for swapping the serial ports.
Host-to-Switcher Instructions
The switcher accepts SIS (Simple Instruction Set) commands through the
RS-232/RS-422 port and Ethernet port. SIS commands consist of one or more
characters per command field. They do not require any special characters to begin
or end the command character sequence. Each switcher response to an SIS
command ends with a carriage return and a line feed (CR/LF = ), which signals
the end of the response character string. A string is one or more characters.

Switcher-Initiated Messages
When a local event such as power-up or a front panel operation occurs, the
switcher responds by sending a message to the host. The switcher-initiated
messages are listed below (underlined).
(C) Copyright 2001, Extron Electronics “DXP88”, Vx.xx
The copyright message is initiated by the switcher when it is first powered on.
Vx.xx is the firmware version number.
Password:
The switcher initiates the password message immediately after the copyright
message when the controlling system is connected using TCP/IP or Telnet and the
switcher is password protected. This message means that the switcher requires an
administrator or user level password before it will perform the commands entered
via this link. The switcher repeats the password message response for every entry
other than a valid password until a valid password is entered.
Digital XPoint Matrix Switchers • Programmer’s Guide4-2
Login Administrator
Login User
The switcher initiates the login message when a correct administrator or user
password has been entered. If the user and administrator passwords are the same,
the switcher defaults to administrator privileges.
Reconfig
The reconfig message is initiated by the switcher when a front panel operation has
occurred, an audio gain adjustment has been completed, or a memory preset has
been recalled.
All Configuration Memory Cleared
The memory cleared message is initiated by the switcher when a system reset has
occurred. See System reset to factory defaults in chapter 3.
The switcher does not expect a response from the host, but the host program might
request a new status.
Switcher Error Responses
When the switcher receives an SIS command and determines that it is valid, it
performs the command and sends a response to the host device. If the switcher is
unable to perform the command because the command is invalid or contains
invalid parameters, the switcher returns an error response to the host. The error
response codes are:
E01 — Invalid input channel number (too large)
E10 — Invalid command
E11 — Invalid preset number (too large)
E12 — Invalid output number (too large)
E14 — Illegal command for this configuration
E24 — Privilege violation
Using the Command/Response Table
The command/response table begins on the next page. Upper- or lowercase letters
are acceptable in the command field. Symbols are used throughout the table to
represent variables in the command/response fields. Command and response
examples are shown throughout the table.
The table below shows the hexadecimal equivalent of each ASCII command.
