Introduction

About This Manual

This manual describes the installation and operation of the Extron MPX 423 A
Media Presentation Matrix Switcher.

About the MPX 423 A Media Presentation Matrix Switcher

The MPX 423 A is a matrix switcher that supports both single and separate
switching modes and merges the following independent switchers into a single,
compact enclosure:

• a 4x2 VGA —UXGA matrix switcher

• a 4x2 composite video matrix switcher

• a 4x2 S-video matrix switcher

• a 12x2 stereo audio switcher
The MPX 423 A has the following video connector types:

• 15-pin HD input connectors for VGA signals

• BNC input connectors for composite video signals

• 4-pin mini DIN input connectors for S-video signals
The audio functions use captive screw connectors shared between three input

groups, and support balanced and unbalanced wiring.
There are three device control options:

PRELIMINARY

Features

• Front panel button control

• Ethernet control (using Telnet or the on-board Web server)

• RS-232 control using Extron SIS

The features of the MPX 423 A Media Presentation Matrix Switcher include:

Multiple video inputs — Twelve inputs including four VGA (or SVGA or UXGA

RGBHV, RGBS, RGsB, or RsGsBs) inputs on 15-pin HD female connectors, four
S-video (NTSC, PAL, or SECAM) inputs on 4-pin mini DIN female connectors,
and four composite video (NTSC, PAL, or SECAM) inputs on BNC female
connectors.

Multiple video outputs — Two outputs per video format for simultaneous (in

separate switcher mode), or one at a time (in single switcher mode) display on
VGA, composite video, or S-video devices.

Audio switcher — The 12x2 audio switcher selects among the audio outputs of

each of the three signal groups.

Audio breakaway — The MPX 423 A provides the capability to break away an

audio signal from its corresponding video signal. Audio breakaway switching
can be controlled via the front panel, Ethernet, or RS-232.

Multiple audio inputs and outputs — Twelve balanced/unbalanced stereo inputs

and two balanced/unbalanced stereo outputs, all using captive screw connectors.

Single switcher mode — Allows for one-touch switching. When one of the 12

inputs is accessed, the signals of the input will be routed to the outputs of its
group. Outputs of the other groups are disconnected, while audio output
remains unaffected.

™

commands

1-2

MPX 423 A • Introduction

Separate switcher mode — Allows for independent switching to the output of any

given I/O group. This effectively divides the MPX 423 A into three separate
switchers in one box.

Current configuration memory — Allows for ties and audio settings to be saved

in nonvolatile memory. When the switcher is powered off and then on again, the
switcher recalls the connections made on the last configuration, including audio
settings.

IP Link™ — IP Link-enabled products offer an integrated Web server with

high performance architecture, global compatibility with industry standard
Ethernet communication protocols, multi-user support, and a Web-based asset
management application specifically designed to work with products that
include IP Link technology.

RS-232 remote control — Allows remote control of the MPX switcher using

Extron’s Simple Instruction Set SIS™), or a third-party control system.

Downloadable firmware updates — The latest firmware can be conveniently

downloaded from the Extron Web site, and updates for new features and
capabilities can be easily upgraded through the IP Link Ethernet port.

Bandwidth — Bandwidth is 350 MHz (-3 dB), typical for VGA video, allowing this

switcher to switch everything from NTSC video to high-resolution computer
signals.

Front panel security lockout — Locks out all front panel functions except for

input/output tie viewing to prevent unwanted setting changes.

Genlock sync (for composite and S-video) — Includes video genlock capabilities

allowing for vertical interval switching and smooth, glitch-free transitions.

Digital Sync Validation Processing (DSVP™) — Includes Extron’s exclusive DSVP,

which allows for the monitoring of input signal status information, as well as the
scan rate for computer signal inputs.

Input audio gain and attenuation (adjustable via RS-232) — Allows users to set

the level of audio gain or attenuation (-18 dB to +24 dB). Individual input audio
levels may be adjusted so there are no noticeable volume differences when
switching between sources. (The default setting is 0 dB.)

Speed-sensitive volume control — Automatic sensitivity control allows the user to

easily fine-tune the audio volume.

Versatile mounting options — The MPX 423 A is housed in a rugged, 1U, full rack

width metal enclosure, and can be easily mounted into any rack or podium, or
under a desk.

Internal international power supply — The internal power supply provides

worldwide power compatibility.

assembly, the operating ambient temperature of the rack environment may
be greater than room ambient termperature. Therefore, consider installing
the equipment in an environment compatible with the maximum ambient
temperature (Tma) specified by the manufacturer (122˚F, 50˚C for the MPX).

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.

Mechanical loading — Mounting of the equipment in the rack should be such
that a hazardous condition is not achieved due to uneven mechanical loading.

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.

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 (such as
the use of power strips).

Switcher Modes and Operation

Figure 3-2 — MPX 423 A matrix switcher front panel

Introduction to single switcher mode

In single switcher mode, the switcher emulates a 1 output switcher with 12 inputs.
When a video input signal is tied to an output, it is routed to the output of the same
video signal format. All other video output signals are muted.

The audio operates independently as a 12 inputs to 2 outputs matrix switcher. See
“Audio” later in this chapter for more information.

N

Introduction to separate switcher mode

In separate switcher mode the switcher emulates three 1 output switchers with 4
inputs. There are three input selection groups on the front panel: Computer, Video
(composite), and S-video. These three groups operate independently from each
other, and each of the twelve inputs can only be routed to its own video output
format group.

The audio operates independently as a 12 inputs to 2 outputs matrix switcher.

Both audio outputs can be configured in single switcher mode; i.e., the unit

emulates two 1-output switchers with 12 inputs each.

PRELIMINARY

N

Both audio outputs can be configured in Separate mode; i.e., the unit emulates

three 2-output switchers with 4 inputs each.

Establishing a tie

When you connect an input with an output in video or audio, you are establishing
a tie. A tie can be a video-only tie (only a video signal is being transmitted through
an output), an audio-only tie (only an audio signal is being transmitted through an
output) or an audio and video (A/V) tie (a video signal and audio signal are being
transmitted together or apart through one or more outputs).

To establish a tie using the MPX 423 A, do the following:

1. Press the I/O button to select a video-only, audio-only, or A/V tie.

2. Select the output using any of the output buttons.

3. Select the input from any of the 12 inputs.

Reading the LEDs

Reading the LEDs of the MPX 423 A matrix switcher is the primary means of
controlling your inputs and outputs. The unit uses a series of LED colors and
actions to indicate the status of each group and/or tie.

Since the video groups share the audio outputs, audio outputs can be muted in

any video group. To avoid unwanted audio mute, select video only or audio only
by pressing the I/O button before muting the selected output.

Mutes are saved to nonvolatile memory. When power is removed and restored,

the mute settings are retained.

To view the mute status, it is recommended to select video only or audio only

(I/O button) and toggle output buttons on any video group. The muted output
LED will blink.

Selecting video & audio (I/O button) to view muted outputs is not

recommended. Blinking output LEDs could also mean an audio or follow-all tie.

Locking and unlocking the front panel

Front panel security lockout prevents accidental switching of inputs from the front
panel. When front panel security lockout is active, the user can only view the ties
in each group; all input buttons and audio functions are locked.

To toggle the front panel lockout on and off, press and hold the I/O button for three
seconds. The Video and Audio LEDs flash twice to indicate a change in the front
panel security status (on or off).

When front panel lockout is on, the user can still view the ties by toggling the I/O
and output buttons. The LEDs of the corresponding inputs light according to their
tie modes.

If you attempt to make a tie in lockout mode, the Video and Audio LEDs flash
twice, indicating that no ties can be made from the front panel. RS-232 and
Ethernet controls are still available when the front panel is locked.

PRELIMINARY

Setting RGB delay

The RGB delay feature clears the screen during transition to a new input source,
which prevents a visible glitch from occurring on the output screen. RGB delay can
be set between 0 and 5.0 seconds in 0.5 second increments.

To use the front panel to set an RGB delay:

1. Select the desired output (1 or 2).

2. Press and hold the I/O and Mute buttons simultaneously for three seconds.
The Video LED and the currently selected Output LED begin flashing.

3. Turn the volume knob clockwise to increase delay time. Input LEDs 1 - 10
come on one at a time as the volume knob is turned clockwise. Each lit input
LED represents a 0.5 second delay. When RGB delay reaches its maximum of
5 seconds (LEDs 1 through 10 on), the Mute LED flashes.

4. Press the I/O button to exit.

For setting the RGB delay through RS-232 or Ethernet control, see chapters 4 and 5.

3-6

Using Genlock sync

The Genlock sync feature locks the sync generators of multiple devices to a single
source which prevents visible glitches from occurring on the output screen during
transition to a new input source. The source at input 5 provides the Genlock sync
signal to all of the Video group inputs. The source at input 9 provides the Genlock
sync signal to all of the S-Video group inputs. This happens automatically when
inputs are connected to inputs 5 and 9. No configuration is required.

MPX 423 A • Operation

Audio

The MPX 423 A is also a 12x2 audio matrix switcher, where any of the 12 inputs can
be routed to one or both outputs simultaneously.

Establishing an audio tie

Regardless of the video switching mode to which the unit is configured (single or
separate), the MPX 423 A also emulates a 12x2 audio switcher.

To make an audio-only tie:

1. Press the I/O button until only the Audio LED is lit.

2. Use any one of the three Outputs buttons to select output 1 or 2 (output LEDs
1 or 2 will be lit in all three video groups to indicate which output, 1 or 2, is
selected).

3. Select any of the twelve inputs (buttons 1 - 12).

The selected input (1 - 12) is routed to the selected output (1 or 2).

Adjusting the input audio level

The audio level of each input can be adjusted from -18 to +24 dB. The factory
default level is 0 dB.

There is only one audio settting which is applied to both the left and right audio
inputs of the selected input device.

Audio level settings are stored in non-volatile memory, and retained through a
power cycle.

When performing the procedure below, you may monitor the Input Audio/Gain
Attenuation level via RS-232 using HyperTerminal (see chapter 4).

To enter the audio adjust mode and adjust an input audio level:

1. Press and hold the Mute button for 2 seconds. The I/O Audio LED and one of

the input LEDs (ex: input 7) flashes indicating the audio adjust mode.

2. Press the desired input button. The selected button’s LED begins flashing.

C

C

3. Turn the Volume control knob clockwise to increase volume and

counterclockwise to decrease the volume level of the selected input.

4. Press and release the I/O button or wait 30 seconds for the unit to exit the

audio adjustment mode.

C

There is no indication of the audio level available by viewing the front

panel. You may monitor the volume level adjustments via an RS-232
connection and HyperTerminal (see chapter 4).

Pressing an input button while in audio adjust mode will

activate / de-activate a tie.

Pressing the Mute button while in audio adjust mode will activate the

mute for output 1.

Resetting the Unit

There are four reset modes activated by a recessed Reset button on the rear panel.
Use a pointed sytlus, Extron Tweeker, or ballpoint pen to activate the Reset button.

The I/O button on the front panel also has limited reset capabilities, described on
the following page.

Hardware reset modes

The available reset modes are listed in the table below.

C

Reset modes close all open IP and Telnet connections, and all sockets.

Reset Modes Description

Mode 1
(Hardware Reset)

Mode 3
(Event Reset)

Mode 4
(IP Setting Reset)

Mode 5
(Absolute Reset)

Holding the Reset button while applying power defaults the unit back
to the base firmware that shipped with the unit from the factory. Event
scripting does not start when the unit is powered on in this mode. This
allows you to recover a unit that has incorrect code or updated firmware
running. All user files and settings are maintained. User Web pages
may not work correctly if the unit is using an earlier firmware version.

Holding the Reset button until the I/O LED blinks once (3 seconds)
followed by a momentary (<1 second) press turns events either on or off,
depending on the current state of the events.

Holding the Reset button until the I/O LED blinks twice (6 seconds)
followed by a momentary (<1 second) press resets IP settings. The I/O
LED blinks four times in quick succession, confirming a Mode 4 reset.
This mode

1. Enables ARP program capability

2. Sets IP address back to factory default

3. Sets subnet back to factory default

4. Sets gateway address back to factory default

5. Turns DHCP off

6. Turns events off

Nothing happens if the momentary press does not occur within one
second.

Holding the Reset button until the I/O LED blinks three times (9
seconds) followed by a momentary (<1 second) press causes a complete
system reset back to factory default conditions. Nothing happens if the
momentary press does not occur within 1 second. The I/O LED blinks

four times in quick succession,

PRELIMINARY

confirming a Mode 5 reset.

Factory reset modes

Factory resets can be set using the front panel I/O button. To reset the MPX 423 A
to factory defaults

1. Press and hold the I/O button on the front panel while plugging in AC power.

2. Continue to hold the I/O button until all LEDs on the front panel flash. Once

the I/O button is released, power-up continues and the LEDs go back to their
default configuration.

Remote Control Port (RS-232)

The MPX 423 A’s RS-232 port connects to a host or controller that generates the
proper command codes and recognizes the switcher’s responses.

N

The cable used to connect the RS-232 port to a computer or control system

may need to be modified by removing pins or cutting wires. If unneeded
pins are connected, the switcher may hinder communication.

See chapter 2,

“Installation”, for more information on wiring the connectors.

The RS-232 connector is a 9-pin D female (see illustration below) with the following
pin designations:

Pin RS-232 Description

1 — not used
2 Tx Transmit data
3 Rx Receive data
4 — not used
5
6 — not used
7 — not used
8 — not used
9 — not used

Gnd Signal ground

The protocol is 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control. The
MPX 423 A is also compatible with the following baud rates: 19200, 38400, & 115200.

Commands and responses for programming the MPX 423 A from a host system
connected to the RS-232 port are listed on the following pages.

PRELIMINARY

Host-to-MPX 423 A communications

The MPX 423 A matrix switcher accepts SIS commands through the RS-232 port or
via Telnet through the LAN port. SIS commands consist of one or more characters
per field. No special characters are required to begin or end a command sequence.
When the unit determines that a command is valid, it executes the command and
sends a response to the host device. All responses from the unit to the host end
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.

MPX 423 A-initiated messages

If you are communicating with the MPX 423 A via RS-232 or via a verbose Telnet
connection, when a local event such as a front panel selection or adjustment takes
place, the unit responds by sending a message to the host. No response is required
from the host. The unit-initiated messages are listed here (underlined).

(c) Copyright 2007, Extron Electronics, MPX 423 A, Vx.xx , 60-683-01]
Day, DD Mon YYYY HH:MM:SS]
Vx.xx is the firmware version number.
The unit sends the boot and copyright messages under the following circumstances:

• If the

unit is off and an RS-232 connection is already set up (the PC is cabled to
the unit and a serial communication program such as HyperTerminal is open),
the connected unit sends these messages via RS-232 when it is first powered on.

4-2

MPX 423 A • SIS Programming and Control

• If the unit is on, it sends the boot and copyright messages when you first open
a Telnet connection to the unit. You can see the day of the week, date, and time
if the unit is connected via Telnet, but not via RS-232. If you are using a Telnet
connection, the copyright message, date, and time are followed by a password
prompt (if set).

Password information

The “]Password:” prompt requires a password (administrator level or user level)
followed by a carriage return.

If the correct password is entered, the unit responds with “]Login Administrator

]

” or “]Login User]”, depending on password entered. If passwords are the

same for both administrator and user, the unit defaults to administrator privileges.

Error responses

If the MPX 423 A is unable to execute a command, it returns an error response to the
host. The error response codes and their descriptions are as follows:

E01 – Invalid input channel number (the number is too large)
E10 – Invalid command
E12 – Invalid output number / invalid port number
E13 – Invalid value (the number is out of range/too large)
E14 – Not valid for this configuration
E17 – System timed out
E22 – Busy
E23 – Checksum error (for file uploads)
E24 – Privilege violation (Ethernet, Extron software only). User privileges have
access to ALL view and read commands, and the following:

• create ties

• set RGB and audio mutes

Exception: User cannot read Admin password
E25 – Device is not present
E26 – Maximum number of connections has been exceeded
E27 – Invalid event number
E28 – Bad filename or file not found

PRELIMINARY

Error response references

The following superscripted numbers are used within the command descriptions
on the following pages to identify commands that may respond as shown:

14

= Commands that give an E14 (not valid for this configuration) response if the

unit’s current configuration doesn’t support that command

22

= Commands that yield an E22 (busy) response.

24

= Commands that give an E24 (privilege violation) response if you are not

logged in at the administrator level.

27

= Commands that may yield an E27 (invalid event number) response.

28

= Commands that may give an E28 (file not found) response.

Copyright information

The following copyright message is initiated by the MPX 423 A matrix switcher at
power-up (for an RS-232 connection):

Commands and Responses

Using the command/response tables

The MPX 423 A can be controlled via a Telnet connection (port 23) or a Web browser
connection (port 80). The ASCII and URL commands listed in the tables starting on
page 4-9 perform the same functions, but are encoded differently to accommodate
the requirements of each port (Telnet or Web browser).

This ASCII to hexadecimal (HEX) conversion table is for use with the command/
response tables.

Figure 4-1 ASCII to Hex conversion table

PRELIMINARY

The command/response tables list ASCII command codes (for Telnet or RS-232),
the corresponding URL encoded command codes (for Web browsers), the unit’s
responses, and a description of the command’s function or results.

The following rules apply for commands and responses:

• Upper and lower case characters may be used in the command field unless
otherwise specified.

• Commands may be sent back-to-back without spaces (for example, 2!65V1Z).

• Numbers can be entered in 1, 2, or 3 digits, e.g., 8V = 08V = 008V.

• Telnet control versus Web browser control differences include:

• For a Web browser, “URL” is used to shorten the examples. “URL” refers
to the full URL of the control interface and Web page, including all path
information (e.g., http://192.168.100.10/myform.htm).

?cmd=.

N

• To send a Web browser command, prefix it with the URL and

• For Web browser, all
the hexadecimal equivalent, %xx, where xx is the two-character hex byte.
For example, a comma (,) is coded as %2C. Characters such as %, +, and
space ( ) must be coded with hex bytes to be interpreted correctly.

• Some characters differ depending on the method used.
Telnet Web browser
Escape = W or (hex 1B) Escape = W [must not be hex encoded]
CR = Pipe (|) or (hex OD) CR = Pipe (|) [must not be hex encoded]

In either method, {Data} = data that will be directed to a specified port

and must be hex encoded if non-alphanumeric.

If you make adjustments (changes to volume, etc.), via the front panel, RS-232

or IP, it takes 100 seconds for the new data to be saved to flash memory.

PRELIMINARY

Ethernet Control

The MPX 423 A matrix switcher features an on-board Web server, displayed as a set
of default Web pages. These pages allow you to control and operate the MPX unit
through its Ethernet port, connected via a LAN or WAN, using a Web browser such
as the Microsoft Internet Explorer (version 5.5 or higher), or Netscape Navigator
(version 6.0 or higher).

This chapter describes these default Web pages, which are always available and
cannot be erased or overwritten.

Accessing and Using the Web Server

Access the switcher through the on-board Web server pages as follows:

1. Double click the Web browser icon on your Windows desktop to launch your

Web browser.

2. Click in the browser’s Address field.

3. Enter your MPX 423 A’s IP address in the browser’s Address field.

The switcher checks several possibilities, in the following order, and then

responds accordingly:
a. Does the address include a specific file name, such as

10.13.156.10/file_name.html?

b. Is there a file in the switcher’s memory that is named “index.html”?

If so, the switcher downloads “index.html” as the default start-up
page.

If neither of the above conditions is true, the switcher downloads the

c.

factory-installed default start-up page, “nortxe_index.html”
(figure 5-2), also known as the System Status page.

Navigating the Default Web Pages

The MPX 423 A default Web pages include four tabs (Status, Configuration, File
Management, and Control) for easy navigation of the administrative options

including system status, password control, file management, and video/audio
settings.

Status tab

The Status tab includes pages that show the current System Status and DSVP data
for the MPX 423 A.

If so, the switcher downloads that page.

System Status page

The System Status page (figure 5-2), is the default page of the on-board Web server,
and provides an overview of the matrix switcher’s status. It provides immediate
system information, power status, and serial port settings for the MPX.

DHCP
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for

automating the configuration of computers that use TCP/IP. DHCP can be used to
automatically assign IP addresses, deliver TCP/IP stack configuration parameters
such as the subnet mask and default router, and provide other configuration
information such as the addresses for printer, time and news servers. For specific
settings information, see your system administrator.

IP Address
The MPX 423 A IP Address field contains the IP address of the connected matrix

switcher. This value is encoded in the flash memory in the switcher.
Valid IP addresses consist of four 1-, 2-, or 3-digit numeric subfields separated by

dots (periods). Each field can be numbered from 000 through 255. Leading zeroes,
up to 3 digits total per field, are optional. Values of 256 and above are invalid.

The default address is 192.168.254.254, but if this conflicts with other equipment at
your installation, you can change the IP address to any valid value.

Edit this field as follows:

1. Click in the IP Address field. The graphic cursor becomes a text cursor.

2. Edit the address as desired.

3. Press the Tab key on the keyboard or click in another field to exit the IP

4. Click the Submit button to make the address change take affect.

Gateway IP Address

The Gateway IP Address field identifies the address of the gateway to the mail
server to be used if the MPX 423 A switcher and the mail server are not on the same
subnet.

The gateway IP address has the same parameters rules as the system IP address.

Subnet Mask

The Subnet Mask field is used to determine whether the MPX 423 A switcher is on
the same subnet as the mail server when you are subnetting.

MAC Address

The hardware address is hard-coded in the switcher and cannot be changed.

Date/Time Settings

The Date/Time Settings fields provide a location for viewing and setting the date
and time functions. Click Local Date/Time to syncronize the MPX’s internal clock
with the PC’s time setting.

Editing the Extron IP address while connected via the Ethernet port can

Passwords page

The fields on the Passwords page are for entering and verifying administrator and
user passwords. Passwords are case sensitive and are limited to 12 upper case and
lower case alphanumeric characters. Each password must be entered twice: once
in the Password field and then again in the Re-enter Password field. Characters in
these fields are masked by asterisks (*****).
