    System Configuration Commands System Configuration Commands command Changing operation mode The V A command described in the previous section queries whether the CU is in conference or microphone mode. Of course, the mode can also be changed using a corresponding protocol command, which is described below. Important Note As already mentioned in chapter 2.2, it is necessary to restart the CU to change the operation mode successfully.
  • Page 18 System Configuration Commands ATTENTION! Use carefully! command Selecting Unicast or Broadcast Mode You can use the M command to switch between the default broadcast mode and the unicast mode when directing commands specifically to MUs. In unicast mode, you can address individual MUs with commands that contain an ' ' at the beginning.

If you want to manage the voting functions of the MUs without further help from the Quinta software, you have to read and manage this list. The Quinta CU-internal MU list is a fixed list of 150 positions (range of list positions: 0x00 - 0x95).

    Voting Commands Voting Commands The voting commands all refer to individual MUs, for example to switch on their voting . Consequently, all MUs must be addressed directly. This assumes that you know the listing of the MUs, since they are addressed under their MU list positions and not via the MU ID.

  • Page 69: Microphone Mode Commands

    Microphone Mode Commands Microphone Mode Commands In addition to conference mode, the microphone mode is another possibility to operate the CU. Most of the typical conference functions of the CU are removed in favour of a multi-channel microphone function. Up to four microphones can be used simultaneously. These four microphones have a permanent audio connection with the CU and are assigned to a specific audio channel and an analog or digital audio output if desired.
  • Page 70 Microphone Mode Commands Commands for Mute Settings There are several mute modes that can be used in microphone mode as shown in the following subchapters. 7.2.1 Mute Mode Settings You can set whether push-to-mute or toggle mute should be used. In push-to-mute mode, the mute button must be pressed permanently to mute.

  • Page 72 Microphone Mode Commands Examples Set Mute Mode to Push-to-Mute & Deactivate Global Mute & Read Mute Settings Transmit: J A 1<CR> The J A command is the first command needed to set the mute mode. In this example the mute mode is set to push-to-mute by parameter 1.
  • Page 73 Microphone Mode Commands Commands for Mute Status This command is used to mute or unmute the individual streams resp. channels of the CU. In addition to setting the mute status, the latter can also be queried; however, this only happens indirectly each time the mute status changes. To set and read the mute status of the four microphone channels, the corresponding DSP register 0x42 is addressed directly.
  • Page 74 Microphone Mode Commands Note At any change of DSP register 0x42, regardless of the source, the CU sends out the actual value read back from DSP, plus a variable service message. In the examples, two of these service messages that can occur are listed; in general, the following three different forms can occur: m=a-zn=b (Example: m=07-zn=02), zmA_B (Example: m=07- zn=02), pcgmN (Example: pcgm0).

  • Page 76 Microphone Mode Commands Remembering Mic Channel (Channel Memory) The so-called channel memory can be activated so that the mic channels remain assigned unchanged when the CU is restarted. It is possible to route the individual channels discretely to the outputs of the CU. In such a case it is very important that the MUs remain on the correct channels even after restarting the CU.
  • Page 77 Microphone Mode Commands MU individual Volume (Channel Volume) In order to adjust the volume of the individual MUs (immediate volume change), it is necessary to directly address the DSP registers, which are responsible for the volume of the corresponding upstreams. Note This command is of the command form which addresses the DSP, reads it or writes into its registers as shown in chapter 8.
  • Page 78 Microphone Mode Commands Example Set MU individual Volume Transmit: P 63 15<CR> This command sets the volume of channel 2 to 0x15; the higher the hexadecimal values, the lower the volume will be.

  • Page 84: Use Cases

    Use Cases Use Cases Remote Microphone Control (static ON/OFF) - applicable in stand-alone as well as PC-controlled mode To switch the microphone of an MU on and off statically without sending a speak request, only the A command has to be sent. In addition to the corresponding MU ID and the bit position for switching on and off, this command also contains information about the hardware type and MU flags.
  • Page 85 Use Cases Scenario IMPORTANT T 0 pp 0 If the command in the optional list query process is not executed, the corresponding information for the correct use of the A command must be taken from the x messages. OPTIONAL: Check List Positions for MU IDs, further information about the MUs and saved Names The list items must be queried for MU ID, further MU information and stored names.
  • Page 86 Use Cases Remote Microphone Control (speak request based) - applicable only in PC-controlled mode In contrast to the direct or hard switching on and off of the microphone of a certain MU, the speak request based remote microphone control means that the MU must first send a q message as a speak request.
