About this Guide
This guide describes the SW2 DP switcher and discusses how to install, configure, and operate it. The terms “switcher” and “SW2 DP” are used interchangeably to refer to the SW2 DP switcher.
About the SW2 DP
The Extron SW2 DP is a two input, one output, DisplayPort switcher that switches DisplayPort video and embedded multi-channel digital audio signals. The SW2 DP is HDCP compliant and supports data rates up to 10.8 Gbps and computer resolutions up to 2560x1600 W 60 Hz.
The SW2 DP switcher can be controlled via the front panel or the RS-232 interface. You can select inputs by pressing the front panel buttons, enabling auto-input switching, or entering Simple Instruction Set (SIS) commands via RS-232.
Features
• HDCP — The SW2 DP checks the sources and display for HDCP compliance. HDCP LEDs for the inputs and output indicate whether HDCP authentication was successful.
• Thunderbolt™ source support — Thunderbolt sources are backwards-compatible with the SW2 DP inputs for DisplayPort audio and video (Thunderbolt devices are not supported on the SW2 DP output).
• Auto-input switching — The SW2 DP can be configured to automatically switch to the active input when the switcher detects a signal. If both input signals are present, the switcher switches to input 1.
• Signal detection LEDs — Both inputs and the output are represented by LEDs on the front panel. Each LED lights if a signal is present for its input or output.
• Input cable equalization — Automatic input cable equalization compensates for signal loss up to 25 feet (7.6 m).
• RS-232 control — The switcher can be controlled via SIS commands issued through an RS-232 computer interface.
• Front panel security lockout (executive mode) — To prevent unauthorized access to the switchers, front panel lock mode can be enabled via the front panel or SIS
SW2 DP • Introduction 2
• EDID Minder — EDID (Extended Display Identification Data) consists of the resolution, refresh rate, and pixel clock information of a display device. The EDID Minder manages this information between the digital output device and the inputs. By maintaining continuous EDID communication with the sources, the EDID Minder ensures that all DisplayPort sources power up properly and maintain their video outputs, whether or not an active signal is displayed.
• A rear panel DIP switch enables you to either keep the default EDID of 1920x1080 @ 60 Hz with 2-channel audio or store the EDID of the connected display at the output so that connection with the display is made quickly and smoothly at each power-up.
• Power supply — An external 12 VDC power supply with a 2-pole captive screw connector accepts 100 to 240 VAC.
• Rack and furniture mounting — The SW2 DP can be mounted on a rack shelf or under a desk or podium with an optional mounting kit.

WARNING:
• Risk of electric shock. Keep the two power cord wires separate while the power supply is plugged in. Remove power before wiring.
• Les deux cordons d’alimentation doivent rester séparés tant que l’alimentation est branchée. Coupez l’alimentation avant de faire les raccordements.
ATTENTION:
• Power supply voltage polarity is critical. Incorrect voltage polarity can damage the equipment. Identify the negative (or ground) lead by the ridges on the side of the cord.
• La polarité de la source d’alimentation est primordiale. Une polarité incorrecte pourrait endommager la source d’alimentation et l’unité. Les stries sur le côté du cordon permettent de repérer le pôle négatif du cordon d’alimentation.
• Always use a power supply supplied by or specified by Extron. Use of an unauthorized power supply voids all regulatory compliance certification and may cause damage to the supply and the end product.
• Utilisez toujours une source d’alimentation fournie ou recommandée par Extron.
L’utilisation d’une source d’alimentation non autorisée annule toute conformité réglementaire et peut endommager la source d’alimentation ainsi que le produit final.
• Unless otherwise stated, the AC to DC adapters are not suitable for use in air handling spaces or in wall cavities. The power supply is to be located within the same vicinity as the Extron AV processing equipment in an ordinary location, Pollution Degree 2, secured to the equipment rack within the dedicated closet, podium or desk.
• Sauf mention contraire, les adaptateurs CA/CC ne conviennent pas à une utilisation dans les espaces d’aération ou dans les cavités murales. La source d’alimentation doit être située à proximité de l’équipement audiovisuel Extron dans un emplacement habituel, avec un degré de pollution 2, fixée à une estrade, un bureau, ou dans une baie technique à l’intérieur d’un placard dédié.
• The installation must always be in accordance with the applicable provisions of National Electrical Code ANSI/NFPA 70, article 75 and the Canadian Electrical Code part 1, section 16. The power supply must not be permanently fixed to a building or similar structure.
• Cette installation doit toujours être conforme aux dispositions applicables du Code américain de l’électricité (National Electrical Code) ANSI/NFPA 70, article 725, et du Code canadien de l’électricité, partie 1, section 16.
• If not provided with a power supply, this product is intended to be supplied by a power source marked “Class 2” or “LPS” and rated 12 VDC, minimum 1.0 A.
• Si le produit n’est pas fourni avec une source d’alimentation, il doit être alimenté par une source d’alimentation de classe 2 ou LPS, avec une tension nominale 12 Vcc, 0,5 A minimum.
To wire the power connector:
1. Cut the DC output cord to the length needed.
2. Strip the jacket to expose 3/16 inch (5 mm) of the conductors.
ATTENTION:
• The length of the exposed wires in the stripping process is important. The ideal length is 3/16 inches (5 mm). If they are too long, the exposed wires may touch, causing a short circuit between them. If they are too short, the wires can be easily pulled out even if tightly fastened by the captive screws.
• La longueur des câbles exposés est importante lorsque l’on entreprend de les dénuder. La longueur idéale est de 5 mm (3/16 inches). S’ils sont trop longs, les câbles exposés pourraient se toucher et provoquer un court-circuit. S’ils sont trop courts, ils peuvent être tirés facilement, même s’ils sont correctement serrés par les borniers à vis.
3. Slide the leads into the supplied 2-pole captive screw plug and secure them, using a small screwdriver.
ATTENTION:
• Do not tin the stripped power supply leads before attaching the captive screw plug to them. Tinned wires are not as secure in the captive screw connectors and can be easily pulled out. They may also break after being bent several times.
• Ne pas étamer les conducteurs avant de les insérer dans le connecteur. Les câbles étamés ne sont pas aussi bien fixés dans le connecteur et pourraient être tirés. Ils peuvent aussi se casser après avoir été pliés plusieurs fois.
4. To verify the polarity of the power cord before connecting it, plug in the power supply with no load and check the output with a voltmeter.
5. Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.

Auto Switch Active LED — This green LED lights when auto-input switching is in effect (see Enabling Auto-input Switching on page 8 for the procedure to set up auto-input switching).2
Input selection buttons and LEDs — Press these buttons to select input 1 or 2. The LED at the right of each button lights when the SW2 DP has power and the corresponding input is selected.• The input buttons are disabled if auto-input switching is in effect; however, the LEDs continue to light to indicate the selected input.
• The SW2 DP retains the previously selected input during a power cycle and the LED for that input continues to light.
The input buttons are also used for enabling front panel lockout (executive mode) and to initiate a system reset (see Enabling Front Panel Lockout (Executive Mode) and Resetting, both on page 14).
3
Signal status LEDs —• Inputs: Each input has a corresponding numbered Signal LED, which illuminates when a source is connected to the input connector and Main Link activity is detected from it.
NOTE: If the source device connected to the selected input is HDCP encrypted (requires HDCP authentication), the corresponding signal LED may not light unless HDCP has been authenticated.
• Output: The Output Signal LED lights when the Main Link signal is being transmitted to a connected output device.
4
HDCP status LEDs —• Inputs: Each input has a numbered HDCP LED. If the connected source is HDCP encrypted, the corresponding input LED lights.
• Output: The Output HDCP LED lights if the connected output device has been authenticated.
NOTES:
• HDCP is re-authenticated on the output whenever a new input is selected.
• The LEDs do not light if the source does not require HDCP encryption or if the display device connected to the output is not HDCP compliant.
5
Config port — Connect a USB cable (USB A to mini B) between your computer and this female USB mini B port to configure and control the switcher via SIS commands and to update the firmware.Operations
Powering On the Switcher
Follow these steps to power on the SW2 DP:
1. Connect all input devices and the output to the switcher rear panel connectors (see Rear Panel Features on page 4 for information on the rear panel connections).
2. Power on the output device.
3. Plug the power supply into the 2-pole captive screw power connector on the rear panel.
• The unit performs a self-test, during which the front panel Auto Switch and Input LEDs each blink once in sequence from left to right. When the self-test completes, the LED for the most recently selected input remains lit.
• Depending on the DIP switch setting, the switcher either reads the stored EDID information or applies the default EDID.
4. Power on the input devices.
Selecting an Input
To switch an input to the output, press the desired input button on the front panel (ensure that auto-input switching is not enabled). The LED corresponding to the selected input button lights.
• To determine the current configuration, check the front panel input LEDs. The one that is lit indicates the selected input. The LED remains lit until a new input is selected.
• Only one input can be switched to the output at a time.
You can also select an input using SIS commands (see the Input Selection commands on page 19. Front panel input selection is disabled when auto-input switching is in effect.
SW2 DP • Operation 1414
Enabling Front Panel Lockout (Executive Mode)
Front panel lock mode (executive mode) disables all front panel controls. Putting the switcher in this mode enhances security by protecting against inappropriate or accidental changes to settings. When the switcher is in lock mode, RS-232 and auto-input switching remain available.
To lock or unlock the front panel, press and hold Input buttons 1 and 2 simultaneously for 3 seconds, then release them. The front panel LEDs blink three times, indicating that front panel lock mode has been enabled or disabled (see the illustration below).

You can also lock the front panel by using SIS commands (see the Front Panel Lockout (Executive Mode) commands on page 19).
Resetting
The following types of reset are available for the SW2 DP:
Factory settings
To reset the switcher to its original factory settings:
1. Disconnect power from the unit if it is connected.
2. Press and hold the Input 1 button while connecting power to the unit.
3. Continue holding the Input 1 button until the power-up sequence completes.
Retain current firmware
To reset the switcher to its default settings while retaining the currently installed firmware version:
1. Press and hold the Input 1 button. The unit performs the power-up self-test, in which all front panel LEDs blink once in succession.
2. When the self-test completes (after approximately 6 seconds all LEDs go dark except the one for the most recently selected input), release the button.
You can also perform this reset by using an SIS command (see the Reset command on page 20).
EDID Minder
The SW2 DP switchers utilize the EDID Minder, which maintains EDID communication to all connected source devices, whether or not the source is selected. EDID information consists of the display resolution, refresh rate, data rate, supported audio formats, and other
features. By factory default, the stored EDID contains information for a native resolution of 1920x1080 @ 60 Hz with 2-channel audio.
During power up, the source devices use an auxiliary channel to obtain Extended Display Identification Data (EDID) from the display device. This allows the output signal to match the resolution and refresh rate of the display device.
NOTES:
• The SW2 DP is fully HDCP compliant. The source negotiates with the SW2 DP input and the display negotiates with the SW2 DP output.
• The SW2 DP does not support DisplayPort Content Protection (DPCP).
• The SW2 DP assigns identical EDIDs to the inputs.
EDID information is read from the display device connected to the output. The learned EDID is stored in memory and is retained after a power cycle or after a new display device is connected to the output. A reset to factory values returns the EDID to the default.
The new EDID is then available when DIP switch 1 is in the Stored (down) position. Each time a new EDID is recorded, it overwrites the existing data and is available when DIP switch 1 in the Stored position.
Storing the Display EDID
1. Connect the display device that will provide EDID information to the output.
2. Power on the display and the SW2 DP.
3. Set DIP switch 1 in the Stored (down) position (see EDID Minder DIP Switch settings for more information about setting the DIP switches).
4. Using a stylus or small Philips screwdriver, press the recessed EDID Store button.
The EDID Minder LED lights amber, then changes to green when the recording process is successfully completed.
Changing the stored EDID
To replace the stored EDID with that of a different display, connect the new display to the output, then repeat steps 2 through 4 of the Storing the display EDID procedure described above.
EDID Minder DIP switch settings
The EDID Minder DIP switch (DIP switch 1, on the left) selects the EDID value that is presented to the source device:
• In the Default (up) position, the EDID value is the factory-stored default, with a resolution of 1920x1080 @ 60 Hz with 2-channel audio.
• In the Stored (down) position, the most recently recorded EDID value is used (this file overwrites previously stored values). Before any other EDID file is recorded, this is also the factory default resolution of 1920x1080 @ 60 Hz with 2-channel audio.
When the DIP switch is in this position, press the EDID button to initiate EDID storing.

Remote
Configuration and Control
This section describes remote operation of the SW2 DP. Topics include:
• Using SIS Commands
• Updating Firmware Using Firmware Loader
Using SIS Commands
The SW2 DP can be remotely set up and controlled via a host computer or other device (such as a control system) that is attached to the rear panel Remote port. Extron Simple Instruction Set (SIS) commands are issued from the computer and transmitted to the SW2 DP via RS-232 (see Wiring for RS-232 Control on page 5 or Connecting to the USB Port on page 6 to connect to these ports).
Host-to-switcher Communications
SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. Enter these commands on your computer and send them to the SW2 DP using a communication software program such as Extron DataViewer. When the switcher determines that a command is valid, it executes the command and sends a response back to the host computer.
Most responses from the SW2 DP to the host computer 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.
Switcher-initiated Messages
When a local event such as an input selection takes place, the switcher responds by sending a message to the host, indicating what selection was entered. No response is required from the host.
The following switcher-initiated message is sent when the switcher first powers up under RS-232 control:
(C)Copyright 20nn,ExtronElectronicsDisplayPortSwitcher, Vn.nn, 60-nnnn-nn
where 20nn is the year, Vn.nn is the firmware version number, and 60-nnnn-nn is the part number of the unit.
NOTE: This copyright message is displayed only at switcher power-up and only under
SW2 DP • Remote Configuration and Control 181818
Error Responses
If the switcher is unable to execute a command it receives because the command is invalid or contains invalid parameters, the switcher returns an error response to the host. Error response codes used by the SW2 DP are:
E01 – Invalid input channel number (out of range) E06 – Invalid input selection during auto-input switching E10 – Invalid command
E13 – Invalid value (out of range)
Using the Command and Response Table
The Command and Response Table for SIS Commands, starting on the next page, lists valid ASCII and hexadecimal command codes, the switcher responses to the host, and a description of the command function or the results of executing the command. The ASCII to Hex Conversion Table below is for use with the command and response table.
