DCHR Firmware Revision History

WD Firmware Update v13Jan2021

DCHR v1.07 (SUPER)/v1.07 (FPGA)

  • Implement Frequency Group sync operations "Send Group" and "Get Group", adding them to the "Sync/Encryption" menu.
  • Separate mix mode settings are now stored for each compatibility mode. When the compatibility mode is changed, the associated mix mode is recalled automatically.
  • When adding a frequency to a group in the Freq Group Edit page, the entry control now defaults to the last frequency added.
  • Default compatibility mode changed to DCHX.
  • The DCHT now conforms to Lectrosonics's new 2-way IR Universal Sync Protocol, meaning that now or soon, it will be able to perform the four basic IR sync operations ("Send Freq", "Send All", "Get Freq" and "Get All") with any other 2-way IR equipped Lectrosonics wireless product.
  • Fix bug causing "tone in headphones" function to fail if test tone is toggled on/off in the "Audio Level" page before enabling the function in the "Test Tone in HP" page.
  • In "Locale" page, allow non-destructive browsing of locale options such that the frequency of operation remains unchanged on exit from the page if the locale setting wasn't changed.
  • AES3 output sample rate is now 48k for all compatibility modes. AES3 output in Duet and DCHX modes, previously 24k, is internally upsampled to 48k.

WD Firmware Update v09Nov2020

DCHR v1.06 (SUPER)/v1.05 (FPGA)

  • Fix bug where audio output type (analog or AES3) not proper re-initialized after invoking the "Tools/Settings->Default" menu option.
  • Fix transmitter battery voltage reporting bug causing erroneous values for digital transmitters whose battery voltage exceeded 3.1 volts.
  • Fixed bug where, in rare cases, a valid transmitted signal was not acquired by the DCHR immediately after power-up.

WD Firmware Update v23Oct2020

DCHR v1.05 (SUPER)/v1.04 (FPGA)

  • Fix bug where, if using Volatile key type, no valid audio was received even though a good RF link was indicated after sending the key to the transmitter.
  • Fix bug where, if using Volatile key type, the Sync/Encryption menu did not show the correct options when viewed after cycling power.
  • When sending a Volatile or Standard key, display count of instances remaining.
  • When attempting to send a Volatile or Standard key over IR, warn user when available key instances are exhausted.

WD Firmware Update v14Oct2020

DCHR v1.04 (SUPER)/v1.03 (FPGA)

  • Initial public release.
