SW4 3G HD-SDI 1 Chapter One Introduction About this Manual Features
Introduction About this Manual The Extron SW4 3G HD-SDI switcher is a four-input, two parallel output, multi-rate switcher. It allows up to four SDI or HD-SDI video input sources to be switched to two identical outputs on female BNC connectors. The SW4 HD-SDI supports multiple SDI rates, including 270 Mbits per second, 1.485 Gbps, and 2.97 Gbps. The switcher can be controlled via the front panel buttons, or via RS-232 communication, using Extron’s Simple Instruction Set (SIS™).

Installation and Operation Installation Overview To install and set up the SW4 3G HD-SDI switcher, 1 Mount the switcher on a 6" or 9.5" deep rack shelf, if desired. 2 Connect up to four video inputs to the switcher’s BNC input connectors 1 through 4. 3 Connect one or two video output devices to the switcher’s BNC output connectors (SDI, HD-SDI, or 3G-SDI). 4 (Optional) Wire the provided 3-pole captive screw plug to your RS-232 cable, and connect the other end of the cable to your computer.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous condition is not achieved due to uneven mechanical loading. 4. Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Consider equipment nameplate ratings when addressing this concern. 5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment.

Select the operation mode for the switcher (the default mode is normal). • Use auto-input switch mode if you want the switcher to automatically switch to the highest numbered input with active sync pulses. (See “Selecting Auto-input Switch Mode,” later in this chapter.) • Use normal mode if you want to change the input manually. 2.

SW4 3G HD-SDI 3 Chapter Three Serial Communication Setting Up RS-232 Communication Using Simple Instruction Set (SIS) Commands Updating the Firmware
Serial Communication Setting Up RS-232 Communication The SW4 3G HD-SDI switcher can be configured and controlled by SIS (Simple Instruction Set) commands via the switcher’s RS-232 port. This port is used to connect the switcher to a host or external controlling device, such as a computer or control system, that can generate the proper command codes and recognize the switcher’s responses. Wire the RS-232 connector as shown below.
Switcher-initiated messages When a local event such as a front panel operation or error condition occurs, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below: (c) Copyright 2008, Extron Electronics, SW4 3G HD-SDI, Vx.xx] The switcher issues the copyright message when it first powers on. Vx.xx is the firmware version number. Inn] The switcher sends the Inn message whenever the selected input is changed using the front panel buttons.
Serial Communication, cont’d Using the command/response table The “Command/response table for SIS commands” begins on page 3-5. The symbols used throughout the table represent variables in the command/response fields. Lower- and uppercase letters are interchangeable, and command and response examples are shown throughout the table. The ASCII to HEX conversion table below is for use with the command/response table.

Serial Communication, cont’d Updating the Firmware Extron periodically updates product firmware in conjunction with the release of new software revisions. When updating any Extron software to the latest revision level, be sure to read the supplied release notes or contact an Extron Application Engineer to determine if your Extron product requires a firmware update.
Loading the firmware to the switcher To load a new version of firmware to your SW4 3G SD-HDI, use the Extron Firmware Loader software. Your computer’s serial port must be connected to the switcher’s RS-232 serial port. See “Rear Panel Connections,” in chapter 2, “Installation and Operation,” for information on connecting to the serial port. 1. If you have not already done so, download the Firmware Loader installer executable file to your computer (see “Downloading the firmware,” earlier in this chapter).
Serial Communication, cont’d 7. Click OK. The firmware selection screen appears. 8. Click Browse to open the Choose Firmware File window, and locate the firmware file that you downloaded. (By default, the firmware file is placed at c:\Program Files\ Extron\Firmware when downloaded from the Extron site.) C 3-10 The firmware file must have a .s19 extension. Uploading any other file type could cause the switcher to stop functioning.
9. On the Choose Firmware File window, double-click on the new firmware file to open it. The Choose Firmware File window closes, and the path to the selected firmware file is displayed in the “Select a firmware file” field on the firmware file selection screen. 10. Click the Upload button. A status bar, which shows the progress of the upload, appears in the Firmware Loader window. The firmware upload to the switcher may take several minutes.
Serial Communication, cont’d When the firmware upload process is completed, the message “Transfer Complete!” is displayed, and the new firmware version number appears in the Current Unit Information field. C 11. 3-12 If the Firmware Loader utility exits before the status bar has progressed completely across the indicator window, the firmware may be corrupted and may no longer respond to commands. Click Exit to close the Firmware Loader.
