Introduction This section gives an overview of the Extron DXP Series Digital Matrix Switchers, describes significant features of the series, and provides application diagrams.
All models feature automatic cable equalization for all inputs and automatic re-clocking for each output. These features reduce the need for additional signal conditioning equipment by compensating for weak source signals or signal loss when you are using long input cable assemblies. The DXP matrix switchers can be operated via the front panel, RS-232 and RS-422 serial control, and IP Link Ethernet control. Optional Extron X-Y remote control panels are also available to operate the DXP switcher remotely.
• Audio breakaway — An embedded audio signal can be separated from its corresponding video signal within the switcher, allowing the audio and video signals from one source to be switched to different destinations • 32 global presets — Frequently used I/O configurations can be saved and recalled as global presets either from the front panel, IP Link, or serial control. This allows I/O configurations to be set up and stored in memory for future use.

NOTE: The illustration on the previous page shows a DXP 88 HDMI, with eight HDMI input connectors and eight HDMI output connectors.
NOTE: LockIt® cable lacing brackets, one for each HDMI input and output connector, are provided with the DXP HDMI. These brackets can be used to secure the HDMI cables to the DXP connectors to reduce stress on the HDMI connectors and prevent signal loss due to loose cable connections. For information on attaching the LockIt brackets, see the LockIt HDMI Lacing Bracket Installation Guide card, available on the Extron website at www.extron.com.
Connections WARNING: CAUTION: Remove power from the system before making any connections. Use Electrostatic discharge precautions (be electrically grounded) when making connections. Electrostatic discharge (ESD) can damage equipment, although you may not feel, see, or hear it. Ethernet Connection When connecting a computer to the DXP Ethernet port, it is vital that you use the correct Ethernet cables, and that they be properly terminated with the correct pinout.
RS-232 and RS-422 Remote Connections The DXP switchers have two serial ports through which the DXPs can be configured via SIS commands (serial commands that control the switcher through this connector). Remote RS232/RS422 port (rear panel) 1 6 9 5 Figure 8. RS232/RS422 REMOTE The following figure shows the pin assignments for the Remote RS232/RS422 connector.
Operation This section describes the DXP front panel controls and the procedures for configuring and operating the DXP switchers.
• Room — A subset of outputs that are logically related to each other, as determined by the operator. The switchers support up to 10 rooms, each of which can consist of 1 to 16 outputs. Each room can have up to 10 presets. • Room memory preset — A configuration consisting of outputs in a single room that has been stored. When a room preset is retrieved from memory, it becomes the current configuration for the outputs assigned to that room only (none of the other outputs are affected).
Input and Output Buttons Each DXP model has the same number of input buttons as output buttons, regardless of how many inputs and outputs it actually has. On models with four inputs or outputs, buttons 5 through 8 behave like buttons 1 through 4, selecting inputs or outputs 1 through 4. The following table summarizes the button functions. Primary Functions 1 Action: 2 3 through 8 Select an input or output for the tie being created.
Secondary functions (•): • Select a global preset (see “Saving and Recalling Presets” on page 32). • Output 1 only: With the Input 1 button, places the switcher in I/O grouping mode (see “I/O Grouping” on page 28). • Mute and unmute an output (see “Muting and Unmuting Video and Audio Outputs” on page 34). Configuration Port c Config port — This RS-232 port is an alternative to the Remote RS232/RS422 connector on the DXP rear panel (see “Rear Panels” on page 6 for a description).
Secondary functions (•): e • In I/O grouping mode, selects group 1 (see “I/O Grouping” on page 28). • In I/O grouping mode, indicates that group 1 is selected. • With the Preset, View <, and Esc > buttons, places the switcher in serial port configuration mode (see “Selecting the RS-232/RS-422 Protocol and Baud Rate (Rear Panel)” on page 42). • Selects 9600 baud for the Remote RS232/RS422 and the RS-232 Config ports in serial port configuration mode.
g Esc > button — The Esc > button does the following: Primary functions (❏): ❏ Cancels operations or selections in progress and resets the front panel button indicators. NOTE: ❏ The Esc > button does not reset the current configuration or any presets. Indicates that the escape function has been activated (flashes once). Secondary functions (•): • In I/O grouping mode, selects group 4 (see “I/O Grouping” on page 28). • In I/O grouping mode, indicates that group 4 is selected.
Secondary functions (•): i • With the Enter button and Audio button, selects between front panel locks (lock mode 2 and lock mode 0) (see “Locking and Unlocking the Front Panel (Executive Modes)” on page 37). • With the Audio button, selects between front panel lock types (lock mode 2 and lock mode 1). • With the Audio button, initiates system reset from the front panel (see “Resetting the System from the Front Panel” on page 38).
Powering On Apply power by connecting the provided IEC power cord to the rear panel IEC connector and to an AC source. The switcher performs a self-test that flashes the front panel button indicators red, green, and amber and then turns them off. An error-free power-up self-test sequence leaves all I/O and control buttons either unlit or showing background illumination. The lit or unlit status of the Video and Audio buttons remains the same as it was when the switcher was previously powered off.
4. Press and release the Enter button to accept the tie or to break an existing tie. 5. Repeat steps 1 through 4 to create or clear additional ties until the desired configuration is complete. NOTES: • Only one input can be tied to an output. If you tie an input to an output that is already tied to another input, the older tie is broken in favor of the newer tie. • If an input with no tie is selected, only the button for the selected input lights (no output buttons light).

SIS Configuration and Control This section describes the serial and Ethernet connections through which the Extron Simple Instruction Set (SIS) commands can be issued, and lists the commands that are available for controlling and configuring the DXP switchers.
Ethernet Port The rear panel Ethernet connector on the switcher can be connected to an Ethernet LAN or WAN. Communication between the switcher and the controlling device can be via Extron DataViewer or Telnet (a TCP socket using port 23). The Telnet port can be changed, if necessary, via SIS. For information on connecting via Telnet, see “Connecting as a Telnet Client” on page 129. The Ethernet connection makes SIS control of the switcher possible using a computer connected to the same LAN or WAN.
Connection Timeouts The Ethernet link times out after a designated period of no communications. By default, this timeout value is set to 5 minutes, but the value can be changed (see the Configure current port timeout command in the Command and Response Table for IP-specific SIS Commands, page 69). NOTE: Extron recommends leaving the default timeout at 5 minutes and periodically issuing the Query (Q) command to keep the connection active.
]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 respond to the commands entered via this link. NOTE: The Password prompt is redisplayed if an incorrect password is entered.
Switcher Error Responses When the DXP 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.

DXP DVI Pro and DXP HDMI Series • Reference Information 126
IP Addressing What is an IP Address? An IP address is a 32-bit binary number that is used to identify each device on an Ethernet network. This number is usually represented by four decimal numbers (called “octets”), each in the range of 0 through 255 and separated by dots; for example, 198.123.34.240. This is called “dotted decimal notation.
The following is an example of an invalid Class C addressing scheme: Device IP Address Matrix Switcher Control Software computer 208.132.180.41 DXP DVI Pro switcher 192.157.180.42 NOTE: The above addresses are invalid because the network identifier for each address is not the same even though each IP address is unique. You can perform a test from your computer to check that a device at a particular address is responding correctly or to determine its address (see “Pinging for the IP Address,” below).
4. At the command prompt, enter ping IP address. The computer returns a display similar to figure 117. The line Pinging ... reports the actual numeric IP address, regardless of whether you entered the actual numeric IP address or an alias name. C:\>ping 192.168.254.254 Pinging 192.168.254.254 with 32 bytes of data: Reply Reply Reply Reply from from from from 192.168.254.254: 192.168.254.254: 192.168.254.254: 192.168.254.
Operating using Telnet It is not the intention of this guide to detail all of the operations and functionality of Telnet; however, some basic level of understanding is necessary for operating the DXP switcher via Telnet. Connecting to the DXP (Open command) You connect to the DXP Plus switcher using the Open command. After your computer is connected to the switcher, you can enter the SIS commands the same as you would if you were using the RS-232 link. Connect to the DXP as follows: 1.
Setting carriage return-line feed Unless commanded otherwise, Telnet transmits a line feed character only (no carriage return) to the connected switcher when you press the key. This is the correct setting for SIS communication with the switcher. The Telnet set crlf command forces Telnet to transmit carriage return and line feed characters when is pressed; however, if crlf is set, the SIS link with the switcher does not function properly.
Subnet masks and octets The subnet mask (figure 120) is used to determine whether the local and remote devices are on the same subnet or different subnets. The subnet mask consists of four numeric octets separated by dots. Each octet can be numbered from 000 through 255. Leading zeros, up to three digits total per octet, are optional. Each octet typically contains either 255 or 0.
