DCR822 v1.50 (SUPER)/v1.35 (FPGA)/v1.02 (BOOT)

  • Adds enhanced Tuning Groups Feature in Main Page Navigation Mode. Quickly tune to specific group entries directly from the main display page. How it works:
    • Configure tuning groups as desired and set the receiver channels to use them.
    • From the main display page, hold down the MENU button. The receiver 1 frequency or name will be highlighted for navigation.
    • Press MENU a second time to highlight the receiver 2 frequency or name for navigation.
    • While in navigation mode, use UP and DOWN to navigate through valid entries within the receiver’s active tuning group.
    • Press MENU to toggle between the receivers.
    • Press BACK to exit the navigation mode.
    When navigating on a page with frequencies:
    • Entries will be ordered by frequency.
    • The display will show the frequency of the current entry.
    When navigating on a page with group entry names:
    • Entries will be ordered by group entry name, then by frequency if the group entry is unnamed.
    • The display will show the selected group entry name or the frequency if the group entry is unnamed.

DCR822 v1.49 (SUPER)/v1.35 (FPGA)/v1.02 (BOOT)

  • Fixed popping sounds heard when tuning away from an active Digital Hybrid signal to a frequency that is not close by. This could happen when tuning groups are used, when frequencies in the list are widely separated.

DCR822 v1.48 (SUPER)/v1.34 (FPGA)/v1.02 (BOOT)

  • In order to save power, the audio output DAC is now powered down any time both output jacks are configured for AES3 mode.
  • Now, when performing a Group Sync IR operation with group "all" selected, the confirmation message appears only after the transaction is complete.
  • Serial commands returning name strings (e.g. "name?") now correctly escape backslashes in the names, should there be any.

DCR822 v1.45 (SUPER)/v1.33 (FPGA)/v1.01 (BOOT)

  • Added the ability to save frequency scan data to an SD card. To do this, choose Save Scan from the SD Card menu.
  • Smart Tune no longer runs slowly if one of the receivers is powered down.
  • Smart Tune now correctly retunes the receiver to the original frequency when a user leaves the page in mid-scan. Previously, even though the original frequency was indicated on the display, the receiver was actually tuned to the last frequency scanned.
  • On the Frequency page, when the kHz field has the focus, pressing MENU+UP or MENU+DOWN now adjusts frequency in 100 kHz steps.
  • In Entry Edit page reached through the Group Edit page, the option to delete an entry is now a toggleable checkbox. To delete an entry, press MENU/SEL to navigate to the "Del" checkbox and press either the UP or DOWN button to check the box. Then press MENU/SEL again to show the "Go" soft button. Pressing the DOWN button will delete the entry and return to the Group Edit page.
  • The UP+DOWN shortcut to open the Frequency page now works whether the device is locked or not.
  • When the device is locked, the Clear Scan page is no longer accessible.
  • The Group Select page (on Group Edit menu) is now accessible when the device is locked,
  • When the device is locked, it is no longer possible to edit Rx Names, Tx Names or the Device Name.
  • When the device is locked, it is no longer possible to change Routing settings.
  • Improved IR Group Sync operation to prevent erroneous failure reports when communicating with older devices.
  • Fixed bug where the Block setting in the TxInfo page did not always correctly restrict the channel's tuning range.

DCR822 v1.42 (SUPER)/v1.33 (FPGA)/v1.01 (BOOT)

  • Improved the Tuning Group "Group Edit" user interface. Extended tuning group entries to include, besides the frequency:
    • An optional user defined "name" given to an entry
    • An optional compatibility mode associated with that entry
  • Decreased the time it takes show the Frequency page when using the "Hold UP+DOWN" shortcut.

DCR822 v1.41 (SUPER)/v1.33 (FPGA)/v1.01 (BOOT)

  • LCD backlight now turns on when a transmitter battery alert condition is detected.
  • Cease display of "Slow card" warnings when recording is stopped.
  • If an SD card format operation is canceled, do not show the "Mounted as data card" message.
  • Fix a user interface "loop" condition arising if an SD card is removed and then quickly re-inserted.
  • Fix a user interface "loop" condition arising at the end of a successful recording recovery operation.

DCR822 v1.32 (SUPER)/v1.31 (FPGA)/v1.01 (BOOT)

  • RF meter scale adjusted to more accurately represent received RF power levels.
  • Added the ability to send and receive all tuning groups at once via IR sync. The new feature is available from the front panel or using Wireless Designer.
  • Band A1B1 and B1C1 units now offer an "AU" locale setting which makes tuning range conform to allowed frequencies in Australia.
  • It is now possible to perform a scan when receiver 1 is powered off. If powered off, the receiver is powered for the scan.

DCR822 v1.30 (SUPER)/v1.30 (FPGA)/v1.01 (BOOT)

  • Now supports control by Wireless Designer via a USB connection. This requires Wireless Designer version 2.0.30 (or higher) for macOS or version 2.0.34 (or higher) for Windows.
  • It is now possible to edit receiver names, transmitter names, and the 30 character device description from the LCD. The "use rx name" checkboxes are now also editable.
  • The device description string from Wireless Designer is now shown on the top line of the About page, right after the word "About". If the description string is long, it will scroll.
  • Group names from Wireless Designer are now included in SD card group load and save operations.
  • IR operations "getall" and "sendall" now use receiver names or transmitter names, depending on the status of the Wireless Designer "use rx name" flags.
  • SmartTune now allows more transmitter coverage choices (adding A1, B1, C1) for digital modes.
  • Navigation through group frequencies is now subject to receiver range limits as well as any additional range limits imposed by locale, compatibility mode, nbblock and stepsize settings.
  • Now upon successful insertion / removal of an audio SD card, the UI stays on the current page
  • Now "get freq" and "get all" report an IR sync error if the target frequency is out of the receiver's tuning range.
  • Rx Power page now displays a single On/Off switch if the receivers are combined in Frequency Diversity mode.
  • Now when scrolling through frequencies in a Hybrid mode through frequencies shared by blocks 470 and 19, the block designator changes only when necessary.
  • RF strip charts no longer show false full scale readings when receiver is powered on.
  • It is now possible to switch to talkback mode during an active RF link.

DCR822 v1.13 (SUPER)/v1.09 (FPGA)/v1.01 (BOOT)

  • Battery alert timer is now adjustable to 100 hours, covering the full range of possible battery timer readings.
  • Tuning group navigation on the Frequency setup page now "wraps" at the limits: UP from the highest frequency in the group moves to the lowest frequency in the group, and DOWN from the lowest frequency in the group moves to the highest frequency in the group.
  • Now, if one of the receiver's PLLs is experiencing an unlocked condition, the frequency display on the main window will blink. Blinking for a second or two when the frequency has just been changed, e.g. due to an IR sync even, is normal. Persistent blinking indicates an error requiring service. Note: This feature applies only to the main window. A blinking frequency display on the Frequency setup page indicates that the currently tuned frequency is not a member of the active tuning group.
  • The transmitter battery timer now rolls at 99 hours 59 minutes. Previously it rolled at 9 hours 59 minutes, which is too short for some newer transmitter models.
  • When using the Stop command in the SD Card menu to stop a recording in progress, the SD Card menu remains on the display. Previously, stopping a recording forced all menus to exit.
  • A bug was fixed wherein the main window link indicator would indicate a good link even in encrypted modes requiring a key, when the receiver had no key. Now a blinking "KEY?" indication is correctly displayed in this case.
  • During active reception of an encrypted digital signal (e.g. D2 mode), visiting the TxBat Type setup screen could result in an incorrect battery type being displayed for a fraction of a second, followed by the correct battery type. Now only the correct battery type is shown.
  • Menus and submenus now return to the same highlighted item when reentered. Exceptions: Menu cursors are reset each time the receiver is powered on, and whenever the "Default" command is issued.
  • Transmitter battery voltage is now displayed correctly in Digital Hybrid compatibility modes in the special case where only the right-hand antenna has a good signal.
  • Now, if a change is made on the Frequency setup page which changes the associated frequency "block" without affecting the frequency, the pilot tone is updated immediately to reflect the change.
  • Now, audio test tones register on the audio meters and appear in any ongoing SD card audio recordings.

DCR822 v1.10 (SUPER)/v1.08 (FPGA)/v1.01 (BOOT)

  • Added HDM compatibility mode.

DCR822 v1.09 (SUPER)/v1.08 (FPGA)/v1.01 (BOOT)

DCR822 v1.09 (SUPER)/v1.07 (FPGA)/v1.01 (BOOT)

  • Fix bug causing Group Sync functions to work only when group U was selected.
  • An "IR SYNC OK" message now appears in response to a successful Group Send or Group Get request.

DCR822 v1.08 (SUPER)/v1.07 (FPGA)/v1.01 (BOOT)

  • Group Sync option has been moved to the IR&Keys submenu.
  • Changing the locale setting now implicitly retunes the receivers as needed to avoid any newly excluded frequencies.
  • When adding a block-ambiguous frequency to a group, the block now defaults to the block most recently selected in editing session.

DCR822 v1.06 (SUPER)/v1.06 (FPGA)/v1.01 (BOOT)

  • Now there are four variants of the home screen, selectable via the BACK button (case 1181). Preference persists through menu accesses and power cycles.
  • Group Sync functionality (sharing tuning group data with other products via IR) was added to the RF Setup menu.
  • IR sync capability brought up to date with Lectrosonics 2-way IR Universal Sync Protocol.
  • In NA Locale, frequency 607.950 MHz is no longer erroneously disabled.
  • In D2 compatibility mode, completely fresh batteries will no longer result in an incorrect battery voltage report.
  • It is now possible to recover interrupted 3-track audio recordings.
  • Receiver is no longer vulnerable to having an invalid compatibility mode type stored in non-volatile memory.
  • Cursor no longer disappears when navigating the Group Add screen.
  • When updating firmware, long file names now scroll so the entire filename can be seen. Also, upon choosing "Exit" from the firmware update menu, "Exiting" is displayed, instead of "Powering Off"
