Polycom SoundStructure Release Notes

1. SoundStructure Studio 1.5.0 Release Notes

January 20, 2011

SoundStructure Studio version 1.5.0 is a release that includes support for using the

Polycom Touch Control with a SoundStructure system.

New Features

•Added support for up to four Polycom Touch Control devices to be added to a

SoundStructure project to be used as a controller for SoundStructure audio conferencing applications. The Polycom Touch Control can be ‘paired’ with either a Polycom HDX system, or with a SoundStructure system. Only one Polycom Touch

Control needs to be added to a SoundStructure Studio project to support pairing with multiple Polycom Touch Controls with a SoundStructure system.

See the SoundStructure Design Guide (revision E), Chapter 11 for detailed information on how to design a project with a Polycom Touch Control and how to integrate the Polycom Touch Control with the SoundStructure System.

See the User’s Guide for the Polycom SoundStructure Systems and the Polycom Touch Control Device for detailed information on how an end-user will interact with the Polycom Touch Control to control a SoundStructure system.

•Changed the UI display for digital_gpio_held on the events page to show true/false rather than open/closed.

•Changed the ‘red’ status LED range on SoundStructure Studio’s wiring page for phantom power voltages to only illuminate red when the phantom power is less than 44V. Any voltage value of 44V and above is a valid phantom power voltage reading.

•Changed the UI for the Signal Generator on the wiring page to show only one virtual channel associated with the first device in a system. As with previous versions, only one signal generator may be part of a system and now the wiring page properly reflects that.

Bug Fixes

•Fixed an issue where SoundStructure Studio would close unexpectedly when editing an event that used phone_flash or phone_redial.

•Fixed an issue where SoundStructure Studio could not show the logic input or output array status properly on the logic page if the array value was larger than 9999

•Fixed an issue where the system could add only the ‘in’ channel of the headset interface adapter if there were no available output channels.

•Fixed an issue where selecting a filter from the EQ page for a virtual channel group would enable the EQ filters for all the channels in the virtual channel group, regardless of whether the EQ filters were previously enabled for a particular virtual

Page 1

Polycom SoundStructure Release Notes

channel. This could result with a virtual channel having more filters enabled than required with the additional filters operating with a flat frequency response.

2. SoundStructure Studio 1.4.1 Release Notes

October 29, 2010

SoundStructure Studio version 1.4.1 is a maintenance release that improves the usability of the SoundStructure Studio user interface and resolves a number of issues including unexpected program closures under various circumstances.

Bug Fixes

•Fixed an issue where the Add/Edit Event dialog box did not show all buttons on Chinese language PC’s.

•Fixed several issues with the project conversion wizard including

oA conversion of a project for one set of devices to another set of devices with one or more HDX microphones may have microphone elements removed from the converted project.

oA conversion of project from a system with a TEL2 card to a system with a TEL1 card could cause SoundStructure Studio to terminate unexpectedly.

•Fixed an issue where it was required to save an online project prior to being able to execute a preset when the Run button was pressed if virtual channel names or virtual group names had been changed since the last time the project was saved.

•Fixed numerous issues that could cause SoundStructure Studio to close unexpectedly while using the preset recorder, events editor, channels, and matrix pages.

•Fixed an issue where SoundStructure Studio could not create a logic array with more than 27 pins.

•Fixed an issue where SoundStructure Studio could not create default call active and call inactive presets for an offline project with an HDX codec and analog microphones.

•Fixed several issues related to automatic event creation including when using push to talk microphones and Toggle All Mics Mute.

•Fixed an issue where odd orders were allowed for Linkwitz-Riley filters. Only even order filters are now allowed.

3.SoundStructure firmware 1.3.3 Release Notes

October 29, 2010

SoundStructure firmware 1.3.3 is a patch release that fixes several issues as described below.

In addition to the firmware file, a sha1sum checksum of the firmware file may also be downloaded to verify the firmware file has been properly downloaded and matches the file on the web site. The contents of this checksum file are shown below.

Page 2

Polycom SoundStructure Release Notes

0bd08cdee082558877622331ea7b90521fc83048 firmware-1.3.3.bin

Bug Fixes

•Fixed an issue where querying the state of an empty virtual channel group (e.g., get mute “Mics” when “Mics” is a virtual channel group with no members) would cause an assertion that would turn the master SoundStructure device’s front panel light yellow and cause the system to stop responding to both API commands and SoundStructure Studio until the system was rebooted.

•Fixed an issue where it was not possible to enable the AMX beacon without causing the SoundStructure device’s firmware to become unresponsive.

•Fixed an issue where log messages were not formatted properly for command buffer overflow messages.

•Fixed several issues with logic arrays including allowing more than 27 pins to be defined, and properly mapping the event action when large logic arrays are used.

4.SoundStructure Studio 1.4.0 Release Notes

May 24, 2010

SoundStructure Studio 1.4.0 is a major release adding a partial preset recorder capability and support for the Polycom Headset Interface adapter.

SoundStructure Studio version 1.4.0 is recommended for use with all SoundStructure designs regardless of the target firmware of SoundStructure devices. There is no minimum firmware version required to take advantage of the features within

SoundStructure Studio 1.4.0.

New Features

The new features of SoundStructure Studio version 1.4.0 are introduced below. For detailed information on using the new SoundStructure Studio, see the SoundStructure

Studio 1.4 primer document that is available on the Polycom website.

Preset recorder

SoundStructure Studio 1.4 includes a preset recorder that allows one to create partial presets simply by starting the recorder and then using SoundStructure Studio’s user interface to change the project settings. The results can be stored to a new partial preset or appended to an existing partial preset.

Headset interface adapter support

The Polycom Headset Interface adapter, 2200-33206-001, has been added as an input/output option within SoundStructure Studio and can be easily added to a project and with all the SoundStructure Studio settings set appropriately.

Auto Route Option

Added the option to not auto-route signals in the matrix when adding channels and creating projects. This option will retain its value between SoundStructure Studio sessions.

Command line argument

Polycom SoundStructure Release Notes

Added support for the command line argument, -connect, to automatically connect to a system when Studio is launched. The connect option can accept an IP address or a serial port.

Automatically Generated Event Names

Automatically created events names now begin with an underscore, “_”, to differentiate the automatically created events from user defined events.

Event Copy Button

Added an event copy button on the Events page to simplify creation of new events. An event can be copied by selecting the event and clicking the event copy button.

Improved wiring report

Wiring report includes physical logic pin connection information.

Bug Fixes

•Fixed some UI issues where sorting events could cause the event under the mouse to have a white background and white font.

•Fixed an issue where renaming a stereo channel via the Edit Channels dialog did not update the wiring page correctly.

•Fixed an issue where MAC addresses were not sorted properly in the Connect to Devices control.

•Fixed an issue where if the SoundStation VTX1000 was the only remote audio source, the SR12 would be selected by default.

•Fixed several assertion errors that would cause SoundStructure Studio to close unexpectedly.

•Fixed an issue where removing a command from a full preset created a partial preset that would mute the system during execution and unmute when finished executing.

•Fixed an issue where after using the project conversion wizard the number of unused inputs for an SR12 was not calculated correctly.

•SoundStructure Studio now allows logic outputs to be used as event sources.

5.SoundStructure firmware 1.3.2 Release Notes

May 24, 2010

SoundStructure firmware 1.3.2 is a patch release that fixes several issues as described below.

9e8d427e83a322c17e46db006efe18c9c40f7017 firmware-1.3.2.bin

Page 4

Polycom SoundStructure Release Notes

Bug Fixes

•Fixed the following issue with SoundStructure systems that have two or more SoundStructure devices running version 1.3.0 or 1.3.1 firmware. In some cases after a large configuration file upload, or in rare cases after a preset execution, some parameters in the SoundStructure system could still have their default values (e.g., muted crosspoints or safety muted) even though SoundStructure Studio displayed the desired settings (e.g., unmuted crosspoints and not safety muted).

•Changed the behavior of the loop drop auto-hangup function to auto-hangup even if there is no phone line plugged into a telephony card.

6.SoundStructure firmware 1.3.1 Release Notes

January 27, 2010

SoundStructure firmware 1.3.1 is a patch release that corrects a difference in how virtual channel group acknowledgments are generated compared to earlier firmware versions.

bfb1a41d51eb9cf474639fc76c04aff49718be2a firmware-1.3.1.bin

Bug Fix

In version 1.3.0 firmware, acknowledgements from virtual channel group commands are not sent to secondary control connections. For example, if SoundStructure Studio were used to mute a virtual channel group, a control system also connected to the SoundStructure system would receive the proper mute acknowledgment for the individual channels in the group but would not receive the mute acknowledgment for the group name.

In addition, if a virtual channel group were used in a preset, or in the action of an Event, correct command acknowledgments would be generated for the individual channels in the group, but not for the group name.

This virtual channel group acknowledgment behavior difference could affect the status of a control touch panel display if the control system is expecting the acknowledgment from the virtual channel group name.

7. SoundStructure Studio 1.3.0 Release Notes

December 15, 2009

SoundStructure Studio 1.3.0 is a major release adding new Events and logic input/output functionality to support the SoundStructure 1.3.0 firmware release (See Section 8 for SoundStructure 1.3.0 firmware details).

It is recommended to use SoundStructure Studio version 1.3.0 for all SoundStructure project designs regardless of the target firmware of SoundStructure devices.

New Features

Page 5

Polycom SoundStructure Release Notes

The new features of SoundStructure Studio version 1.3.0 are introduced below. For detailed information on using the new SoundStructure Studio and firmware 1.3.0 features, see Chapter 9 in the revision D, or later, SoundStructure Design Guide. The

SoundStructure Design Guide may be found from the help menu in the version 1.3 SoundStructure Studio software.

Events

SoundStructure Studio version 1.3.0 introduces the Events page for creating and editing events. Events are a very flexible way to cause specified actions to occur based on a source and a trigger and are used to connect logic input pins to control settings within SoundStructure such as executing presets based on logic pin changes, or muting microphones based on a button push. Events are also used to integrate the HDX IR remote controller with a SoundStructure device, allowing the different key presses to execute functions within SoundStructure such as taking the PSTN interface offhook, dialing digits, or muting microphones.

Integrated support for push-to-talk microphones

SoundStructure Studio includes automated support for creating projects with push-to-talk microphones through the new logic input mode and logic output mode options available on the edit channels page. It is possible to add up to 128 push-to-talk microphones and their associated LED indicators at the same time the microphones are added to the project.

Push-to-talk microphones are supported by SoundStructure events and all the events are created automatically as the microphones are added to the project.

HDX/SoundStructure integration uses Events

The SoundStructure integration with HDX no longer requires the names “Mics” and “Amplifier” as the integration behavior is implemented with Events that may be customized.

These events are added automatically when an HDX video codec is added to a project.

These events allow bi-directional control between a SoundStructure system and an HDX video codec system. This allows the SoundStructure system to mute an HDX video codec and have the mute icon displayed on the video display.

HDX IR remote support added

SoundStructure Studio supports adding an HDX IR remote to a project and automatically creates the events required to support the different IR key presses.

Configurable Peak Hold Meter

SoundStructure Studio supports different options for the Peak Meter including a One second peak hold, Peak decay, and Infinite hold until the peak is reset.

Logic

The new logic page is used for viewing the current status of defined logic input and output pins, and for changing parameters such as the digital_gpio_hold and digital_gpio_repeat times and the logic pin names. There is a new Edit Logic interface for defining digital logic input pins and arrays, digital logic output pins and arrays, and analog logic input pins.

Last run partial preset

Added last run partial preset to the bottom status bar of SoundStructure Studio.

Polycom SoundStructure Release Notes

Windows Vista and Windows 7 Support

Added support for Windows Vista and Windows 7.

Bug Fixes

•Fixed an issue where the matrix page would appear much smaller than the overall screen size when large fonts were used or with certain foreign language versions of Windows.

•Fixed an issue where SoundStructure devices running 1.1.5 firmware could not be discovered over RS232 with SoundStructure Studio 1.2.1.

•Fixed several file transfer time outs during large configuration setting transfers.

•Fixed an issue where if a telephone line had been auto-hungup due to loop drop detection, then when the phone was taken offhook with SoundStructure Studio, the last telephone number dialed would be dialed again.

•Fixed an issue where some crosspoints were not selectable until a different crosspoint was selected at which point the first crosspoint could be selected again.

•Fixed an issue where selecting two Polycom HDX video codecs for a project would not fully route the audio between the video codecs.

•Fixed an issue where changing the name of a virtual channel group would not change the original virtual channel group name used in partial presets to the new name.

•Fixed cases where the edit devices wizard would change the wiring of the system when only the presence of a TEL card was the difference from the designed project and the target hardware.

•Fixed an issue where deleting and rearranging HDX microphones on the wiring page would cause the microphone green dots indicators on the wiring page to become unsequenced.

8.SoundStructure firmware 1.3.0 Release Notes

December 15, 2009

SoundStructure firmware 1.3.0 is a major release adding significant new functionality to SoundStructure systems, numerous performance improvements, and several bug fixes.

In addition to the firmware file, a sha1sum checksum of the firmware file may also be downloaded to verify the firmware file has been properly downloaded and matches the file on the web/ftp site. The contents of this checksum file are shown below.

a7d7818ce34028d14973d7a8039a5a5e9ada2e90 firmware-1.3.0.bin

New Features

The new features of SoundStructure firmware version 1.3.0 are introduced below. For detailed information on using the new SoundStructure Studio and firmware 1.3.0 features, see Chapter 9 in the revision D, or later, SoundStructure Design Guide. The

SoundStructure Design Guide may be found from the help menu in the version 1.3 SoundStructure Studio software.

Events enable Logic input and output pins and the HDX IR Remote

Page 7

Polycom SoundStructure Release Notes

SoundStructure firmware version 1.3.0 introduces the concepts of Events where events can be used with logic input pins to execute SoundStructure commands including executing presets or setting the value of logic output pins.

Added new parameters digital_gpio_held, digital_gpio_hold_time, and digital_gpio_repeat_time to add more options for using the logic input pins.

The HDX IR remote, with the addition of external IR receiver that connects to the

SoundStructure rear panel, may be used to control SoundStructure devices with events. Key presses on the IR remote can cause events to execute commands on SoundStructure allowing full control of a SoundStructure telephony interface.

Zero Configuration Network Support

SoundStructure devices running version 1.3 firmware will default to the link-local IP address of 169.254.1.1 if the SoundStructure is configured for DHCP and there is no DHCP server available to provide an IP address when the SoundStructure device powers up. This makes it possible to connect to a computer directly to a SoundStructure device with either a straight-through or crossover Ethernet cable without either having to set a static IP address or having a DHCP server available.

10 New Ring Tones

10 new ring tones have been added to the SoundStructure telephony interface. The ring tones are selected with the new SoundStructure parameter phone_ring_tone. The default ring tone is the traditional phone ring tone (phone_ring_tone = 1)

Autohangup based on Call Progress Tones

SoundStructure firmware version 1.3 includes the ability to automatically hang up any of the SoundStructure PSTN phone interfaces based on the call progress tones of busy, fast busy, and offhook. There is a new SoundStructure parameter, pstn_auto_hangup_call_prog_en, that enables or disables this functionality. The default value is disabled.

Serial port broadcast mode

SoundStructure firmware version 1.3 includes a broadcast mode for the serial port that allows the SoundStructure device to send commands to other devices. The serial port may be in one of two modes – command or broadcast. The default mode for the serial port is command mode. Command mode is compatible with third party control systems such as AMX and Crestron and allows the SoundStructure system to be fully controlled or configured. Broadcast mode allows the SoundStructure device to send arbitrary commands from the selected serial port to control other devices. When in broadcast mode, any data received on the serial port is ignored.

Pause the command processor

SoundStructure firmware version 1.3 adds a new parameter, sys_pause, that pauses the system’s command processor for the specified number of milliseconds. This means that any commands that are sent to SoundStructure from a control system or from

SoundStructure Studio will be queued up and not executed until the sys_pause time has passed. The parameter sys_pause can be used to add delays in the command processing system. For example, to create a one second tone burst, a partial preset could be created

Page 8

Polycom SoundStructure Release Notes

that unmutes the signal generator to an output, pauses for one second, and then mutes the signal generator

Signal Activity Meter

SoundStructure firmware version 1.3 includes a signal activity meter. This meter can be used as a source with the events engine. The threshold for the signal activity is set for all audio channels at once with the signal_activity_thresh parameter.

Version 30 HDX Microphone Firmware

SoundStructure firmware version 1.3 includes the version 30 firmware for the Polycom

HDX microphones. Version 30 firmware makes more efficient usage of the microphone resources and reduces the power requirement of the HDX microphones. Updating the SoundStructure firmware to version 1.3 will automatically cause HDX table and ceiling microphones that are connected to the SoundStructure device to be updated if there is no HDX video codec connected to the SoundStructure device over conference link. Current HDX video codec firmware releases include version 30 firmware.

Support for 40 ft OBAM cables

OBAM has been improved to support 1394b Beta cables with lengths of up to 40ft. Standard high quality 1394b Beta cables may be used with SoundStructure. A 40ft OBAM cable is now available from Polycom with part number 2200-43229-001.

Faster Preset Execution

The execution speed of both partial presets and full presets has been significantly improved. Partial presets may be used more efficiently now for volume control, changing routing settings, and other simple changes to the system. Full presets execute faster on SoundStructure systems.

Reduced boot time

SoundStructure systems built from either single devices or large multi-device systems will finish the boot process in under two minutes.

Static IP address improvements

Static IP addresses of SoundStructure devices now remain with the device regardless of whether a device has been OBAM linked with other devices or has a configuration file that doesn’t match the hardware (yellow front panel LED state).

Stereo linking for dynamics and AGC

Stereo virtual channels now have the dynamics and AGC processing of both left and right channels linked together to ensure the stereo image is not affected by gains applied to the underlying left and right channels.

Synchronized clink mute state

Using SoundStructure events and the new SoundStructure parameter clink_mute, the clink mute state can be synchronized across multiple SoundStructure devices that are linked with OBAM. This ensures that the status LED light on HDX table microphones are synchronized across multiple SoundStructure devices.
