v0_90:

Initial version put into the field.

v0_91:

* Added Rollcall button to Peripherals Settings page.

* Displayed Peripheral IP’s on Peripherals Settings page.

* BUG: Displayed version as 0.90 on HMI

v0_92: (never installed in any stations)

* Added Load/Save Configuration to/from a file.

* Added support for individual volumes on two amp peripherals.

* Added support for day/night volume settings and resets.

* Finalized Maintenance page layout on HMI with useful buttons.

v0_93:

* Added Controller Software page and support for updating 

  controller software images through the web interface.

* Display current version in sc_remote.cgi

* Peripheral code version 6 (fixed bug in periph code, wasn’t 

  setting got_volume_packet = 1)

v1_00:

* Changed peripheral volume scale from linear to exponential, to

  increase the range of low volume settings available.  Volume

  (dB) should now ramp linearly.

* Added the ability to disable up to all but one of the units

  assigned to a device using the menu and volume up/down buttons

  on a peripheral.  The units assigned to a device are all

  reenabled at indoor day and night start times.

* Added customizable strings and multiple selectable tones for

  up to four telephone ringdowns on the ATU on the “Station 

  Settings” page of SC Remote.  Ringdowns 3 and 4 are options for

  the ATU’s two auxillary inputs.

* Added “Common Lights” auxillary output function for the ATU.

* Added “Power Failure” auxillary input function for the ATU.  A 

  closure on an input with this function selected will display

  a warning on the touchscreen and generate a log entry.

* Added a “Test Dispatch” page to SC Remote, to generate internal

  station or unit based test dispatches.

* Added a “Station Statistics” page to SC Remote.

* Added a complete logging system to log all system events,

  actions taken during dispatches, peripheral communication events,

  all configuration changes, and optionally all DARCOM traffic.  

  Logs can be viewed from the “Logging” page in SC Remote.

* Moved “Monitor On” and “Monitor Off” buttons to the main 

  touchscreen page, and made them accessible without needing to be

  authenticated.

* Peripheral code version 9.

* Improved network printer communication code, fixes a possible 

  delay before the ATU plays a tone at the beginning of a 

  dispatch.

v1_01:

* Added SSL support to Apache, now all HTTP requests are

  redirected to HTTPS.

v1_02:

* Fixed bug where the touchscreen HMI would be updated before

  the dispatch text was processed during a dispatch.

v1_03:

* Fixed yet another bug related to moving message parsing and 

  printing to after ATU tone generation.  Only affected the log

  file.

v1_04:

* ATU Tone packet was failing to make it through because the ATU

  was not ready to receive another connection in time due to the

  new order of operations during an alert.  Added 20ms delay.

v1_05:

* Modified main program to only reset the peripheral unit settings 

  at Indoor Day Start time.

v1_06:

* Now sends ACK packets immediately before doing anything 

  potentially time-consuming and throwing off communications.  

  (Logging operations were resulting in retried messages.)

* Fixed logging message for “Printer X is responding.”, could have 

  incorrect printer name listed.

* Changed link status code so that any packet received with a 

  valid CRC will bring the link up, and the ATU is kept properly 

  informed of the link status.  This fixes an issue where a 

  dispatch received while the link was down would not be processed 

  properly by the ATU.

* Made the ATU default to a link up status, to bring it into sync 

  with the controller’s default state.  Also fixed a possible 

  communications problem where the controller would be unable to 

  initiate a TCP connection to the ATU if the ATU was busy.

v1_07:

* Fixed a bug in the SLIP code.  Was using the same value for the 

  CTS polling interval and the keydown delay.  Changed it from 

  20ms to 1ms in 1.06 to make CTS polling faster, caused the 

  keydown delay to be too short, caused intermittent problems with 

  MDS 9710 radios.  CTS polling is now 1ms, and keydown delay is

  20ms.

v1_08:

* Added preliminary UDP DARCOM-over-IP support.

* Added Distributed I/O Rules support, and a new page in SC Remote 

  to configure rules.

* Rewrote peripheral rescue support.  Improved rescue 

  functionality by always storing the most recent IP for each 

  peripheral and prefilling DHCP database with last known good 

  IPs.  Now a single click should repair any device which failed 

  to be updated.

* Made peripheral socket only listen on internal network 

  interface.  Network connection attempts from the outside network 

  were causing phantom peripherals with invalid MAC addresses to 

  show up.

v1_09:

* Fixed bug that would cause controller to display “Link Up” 

  indefinitely when booted and then never connected to a radio or 

  network link.

* Made controller inform the ATU that the link is up on boot, to 

  prevent a race condition where the controller would send an 

  alert and the ATU would immediately end it.  This would occur if 

  the link went down, and the controller was rebooted while the 

  ATU remained powered up.

* Completed UDP alerting support, controller now requests 

  personality download over IP if selected as the primary 

  interface.

* Made network printer interactions time out, to prevent a 

  situation where the system could hang while communicating with 

  an Oki printer that was out of paper.

* SC Remote:  Added an option to the Station Settings page for 

  printing a copy of the dispatch text for each unit being 

  alerted, helpful for stations without MDTs.

* SC Remote:  Added “Rollcall Off” button to Peripherals Settings 

  page.

v1_10:

* Added support for Advantech TPC-1270 touchscreen computer.  This 

  requires a new kernel version to be installed on the CF card.  

  This will require imaging a new CF card to upgrade pre-v1.10 

  stations to v1.10 and later.

* Fixed a communications error that could cause one or more 

  peripheral devices to become unresponsive shortly after boot, 

  when using certain ethernet switches.  Linksys SRW224G4 

  switches were not affected.

* Added support for playing Speex-compressed dispatch audio files 

  based on a URL in the printer-text section of a dispatch.

* Added support for displaying custom message-sign text along with 

  unit identifiers.

* The controller now informs the ATU of all link status changes, 

  fixing a bug that would cause the system to occasionally fail to 

  play audio when a dispatch was received while the system was in 

  a link-down state.

v1_11:

* Added pager tone decoding user interface and backend to the 

  Station Controller.

* Expanded audio input configuration capabilities.  The ATU audio 

  inputs can now be individually assigned priorities, mixing 

  behavior for both during alerts and while non-alerted, and can 

  be set to trigger speakers/message signs upon activity detection 

  (to support, for example, an Intercom.)  Default settings will 

  match the behavior of previous releases.

* Audio inputs that are set to trigger message signs and speakers 

  on activity can now be assigned to an “Audio Zone” of either 1 

  or 2.  On the Station Area Settings page, there are two 

  checkboxes for each Station Area: Audio Zone 1, and Audio Zone 2.

  Using these checkboxes, an area of a station can be configured 

  to enable speakers/signs for either one, both, or neither of the 

  audio zones.  This will allow multiple intercom zones within a 

  station.

* Modified audio-URL code to automatically replace the provided 

  host IP with the Gateway IP as configured on the Station 

  Settings page.  This is a workaround to accommodate stations 

  behind NAT gateways.

* Security related software upgrades in this image:

– Updated OpenSSL to 0.9.8h.

– Updated Apache to 1.3.41.

– Updated Mod_ssl to 2.8.31-1.3.41.

– Updated OpenSSH to 5.1p1.

v1_12:

* Improved tone decoder functionality.  Users can now select from 

  one of three modes:  Disabled, Enabled During Link Down, and 

  Always Enabled.  Added a selection for the local tone as well.

  Fixed a flaw that would cause a two-tone sequence with less than 

  50hz separation between tones to fail to be detected.

* Added a Date/Time setting dialog to the Station Settings page.

* Added a Distributed I/O option to have a rule cause a Monitor On

  or Off command to be sent to all peripherals.

* Added tones, and modified Test Dispatch page to allow all tones 

  to be used (not just the original three.)

* Fixed ATU Common Lights bug.

* Fixed possible ATU behavior bug when Link Down and tone decoder 

  active.

v1_20:

* Initial support for the ATX Mainboard

v1_21:

* Added three new tone MP3’s for Pueblo Colorado.

v1_29:

* Peripheral version 18, fixes Monitor issue with audio-triggered

  alerts.  Previously, the ATX could become stuck with its audio 

  disabled if an audio-triggered alert occurred while Monitor mode 

  was on.

v1_30:

* Fixes sc_remote mounting ext3 as ext2 issue.  This will resolve 

  the issue where occasionally the Controller Software Update 

  process would complete very slowly.

* Fixes Monitor On/Off handling on ATX during alert.  The ATX 

  would incorrectly ignore Monitor On/Off messages during an 

  alert.

* Updated SSL Configuration for PFD.

* Peripheral version 19

v1_31:

* Fixes behavior for audio inputs that are both “Disabled” and 

  used to trigger a Display Alert.

* Peripheral version 20

v1_32:

* Increased stack allocation on the ATX microprocessor.  Prior to 

  this change it was possible for a certain path of execution to 

  overflow and overwrite audio input #1’s configuration.

v1_33:

* Changed “Master Volume” to “POE Audio Bus Master Volume” to 

  clarify its actual function.

* Removed “Tone Volume” option on the ATX.

* Fixed a bug where a tone from a newly received dispatch could 

  play over the currently playing speech file.  Tones will now 

  stack correctly.

v1_34:

* Fixed bug where self-generated dispatches could be confused as 

  duplicate alerts.

v1_36:

* Added tones 18-20 for Bolingbrook, IL

v1_37:

* Fixed logic bug in peripherals triggered by Doorbell events.

* Peripheral code revision 22.

v1_43:

* Peripheral code revision 23.

* Added unit status message support

* Added HMI buttons for Ft. Worth: Clear Alerts, Local Alert, 

  Alert Lights.

v1_45:

* Station Status Block messages implemented.  This sends the state 

  of the peripherals (inputs, outputs, responding, mac address, 

  name) to the Communications Gateways on events and periodically.

* Gateway can now control outputs on individual devices remotely.

v1_46:

* Added “Reboot and Recalibrate Touch Screen” action to System 

  Reboot page on SC Remote.

* Changed HMI to use “Speaker Auto/Speaker On” instead of monitor 

  on/off broadcasts.  This speaker-override state is a new 

  station-wide setting that persists through reboots and can be 

  remotely controlled.  Room remotes retain the individual ability 

  to use monitor mode.

v1_48:

* Fixed TPC-1260 compatibility issues.

* Added ALERT semaphore, fixes possible race conditions

v1_49:

* Changed all references to “monitor on / off” to “speakers on / auto”

* Made locally-generated alerts not affect link state

v1_50:

* Added Communications Link Up / Down IO Triggers

* Peripheral version 25: fixes link-down ringdown behavior on ATX 

  board

v1_51:

* Longer polling timeout on SLIP receives, for City of Mesa’s data

  radio system.

* Fixed bug in the URL mangling when a dispatch is received with a

  speech URL over the radio and not the network.

v1_52:

* Changed tone 2, now alternates twice as fast for PFD.

* Added descriptive names for all alert tones, and made the full

  list of tones available for I/O triggered alerts, Tone Decoder

  alerts, and Test Dispatches from SC Remote.

* Extended timeouts before and after doorbell tones.

v1_53:

* Added USB UPS monitoring, and I/O rule triggers.

* Added new functionality to the ATU/ATX firmware, allows the

  controller to mute all audio inputs, to silence the gap between

  local tone and the beginning of synthesized speech playback.

* Added a checkbox to the Station Settings page to disable

  volume resets on room remotes.

v1_54:

* Added DTMF decoder support

* Peripheral version 28

v1_55:

* Improved real-time feedback from the controller software page

  of SC Remote.

* Improved Distributed I/O Settings page of SC Remote.

v1_56:

* Added new I/O Rule outputs, add/remove a unit from a station area.

v1_57:

* Changed muting functionality to only activate if the speech file

  has been downloaded before the local tone ends.

* Disabled all speech download/muting functions when audio input

  2 is set to disabled from the Station Settings page.

* Peripheral version 30

v1_58:

* Increased DTMF tone threshold decay rate to compensate for AGC.

* Fixed issue where the LED sign connected to the ATX Mainboard

  would lock up if no Display setting had been selected from the

  Peripheral Configuration page.

* Peripheral version 31

v1_59:

* Added tones 26 – 32 for Mesa, AZ.

* Fixed issue with TPC-1260 touch screens intermittently failing

  to play downloaded synthesized speech files.

* Added “Field Notes” page to SC Remote, a free form text area that

  gets saved to flash.

* HMI now defaults to “Link *Down*”.

* Removed root password, ssh access is now via public key

  authentication only.

v1_60:

* Peripheral version 32

* Added ability to adjust tone volume on the ATX

* Fixed problem with the “Field Notes” page that could result in

  data loss on reboot.

* Added support for HDTV Remote peripheral type.

* Added ability to split a message remote into two zones.  In this

  mode, the two relay outputs on the message remote are used to

  zone the audio outputs.

v1_61:

* Peripheral version 33, support for Rev. E ATX Mainboard.

* Added lj5mono ghostscript driver option as an alternative

  PostScript renderer.  This fixes some problems with certain

  printers.

* Changed Room Remote software to allow Monitor mode to override

  the station-wide “Speakers On / Speakers Auto” state.

v1_62:

* Added SIP client support.  Multiple SIP extensions can be

  configured, registered or not.

* Added new IO rule trigger for incoming calls on SIP extensions.

* Updated tones 26-32 for Mesa, AZ.

* Fixed issue upgrading firmware on PIC-based peripherals powered

  from the ATX mainboard.

v1_63:

* Fixed memory leak in touch screen interface.  The memory leak

  affected versions v1_60 through v1_62.  Any systems running those

  versions should be updated to v1_63 as soon as possible.

* Initial support for new G2 Color Indicator Remote.

v1_64:

* Improved HDTV Remote protocol

* Fixed log spam from acquiring Realspeak license

v1_65:

* Station Area selection screen in the HMI.

* Limited distribution, interim release for San Diego.

v1_66:

* Fixed UPS detection in new kernel for TPC-1271

* Added I/O support for Color Indicator Remote

v1_67:

* Peripheral version 35

* Added separate Turnout Timer Duration setting.  If left at 0,

  the system behaves exactly as before.  Otherwise, the turnout

  timer on the ATX, Sign Remote, and Message Remote will use the

  specified timeout, and will keep running even after hitting the

  “Clear Alerts” button.

* Now mutes all audio inputs except for audio input 2 when rendering

  speech locally, to mirror the behavior of network-downloaded

  speech files.

v1_68:

* Peripheral version 36

* Added separate audio input volume settings for “Alerted” vs.

  “Not Alerted.”  This allows monitoring radio traffic at a low

  level, but increasing the volume when alerted, for example.

* Added the ability to temporarily disable zoned alerting.

  Controlled from the touch screen or via IO rules.

* Added “Re-print last call” IO action

* Added option to restrict all touch screen controls to the “Station

  Settings” page of SC Remote.

* Added ACT Ambulance / Fire tones (tone numbers 33 and 34)

v1_69:

* Removed 64×32 character restriction on printer text.

* Fixed bug where message text would not be displayed for IO

  Rules that trigger unit-based alerts.

* Fixed issue where Color Indicator IO Rules with timed actions

  would only act on a single Color Indicator Remote.

* Added calls to Comm. Link IO Rules when the link up/down condition

  ends.  Previously, a Link Down IO Rule would only trigger once,

  when the link went down.  If the IO Rule was set up to play a

  looping tone, the tone would continue looping indefinitely even

  after the link was restored.  Now looping tones will end properly

  when the link comes back.

* Fixed issue where Turnout timers would sometimes count up

  indefinitely.  This was caused by an overflowing message sign

  string writing over the turnout timer duration field internally.

* HDTV Remotes now update their clocks twice a day to avoid drift

  and handle DST.

v1_70:

* Fixed bug introduced in 1.69 that affected message sign text 

  strings over 50 characters

v1_71:

* Fixed graphical glitch on the “Station Areas” page of the touch

  screen interface.

* Added “Tone Capture Level” adjustment to the Tone Decoder and 

  DTMF Decoder pages in the web interface.  This allows the level

  of the signal used for tone decoding to be attenuated by the ATX

  Main Board.

v1_72:

* Added “Plain Text” printer support.

* Fixed issue with tone decoding on some model 1271 Advantechs

  when connected to the ATX Mainboard with a mono audio cable.

v2_00 – v2_03:

* Moved to new buildroot filesystem.

* Updated HMI color scheme.

* Vocalizer local speech.

* Added support for new generic “announcement” message type.
