This driver controls the Nexus Audio multi-zone audio system. It currently supports the C6 and C6-e models, and potential other models in that family in the future. This system supports six input sources that can be routed to any of the available output zones.
This driver was not available until after the last formal release, so it is available for download as a driver pack under the Downloads tab, in the Driver Packs sub-section. It will be added to the next formal release.
None known at this time
The parameters are 9,600 baud, 8 bits, one stop bit, no parity.
This section lists the fields that the driver makes available, their types, minimum and maximum values, etc...
The xx symbol in the fields represent a zone number or keypad number and so forth. The valid range for the xx part of the name will be indicated in the field description.
Name Type R/W Description/Limits ControllerCurrentFrequency String R Display what frequency the Tuner is on. The reply will be ‘FM’ or ‘AM’ followed by the frequency. Example: ‘FM 105.9’ or ‘AM 1010’ ControllerFrequencyAM Card W Set the AM frequency of the C6 internal tuner. If the tuner is on the FM band, it will switch to AM. Valid values are 530 - 1710 ControllerFrequencyFM Card W Set the FM frequency of the C6 internal tuner. If the tuner is on the AM band, it will switch to FM. Valid values are 0875 - 1079 ControllerGroup String R/W Create or display a group. The source and volume of the group should be set with the ControllerGroupSource and ControllerGroupVolume fields previously. Bitmask is the decimal equivalent of a binary weighted sum of the bits which are set (in the group). Value is xxyyzz where xx=bitmask for zones 1-6 valid range 01- 63
yy=bitmask for zones 7-12 valid range 01- 63
zz=bitmask for zones 13-18 valid range 01- 63
Example: to make zones 1 and 3 as a group, set a value of 050000
Example: if there is a group with zones 2 and 4 in it, the field value will be 120000.ControllerGroupSource String R/W Set/get the input for the group. If there is already a group, their source will change. If there is no group, nothing will happen, but any subsequent groups created with ControllerGroup field will set their inputs to the input specified by ControllerGroupSource. Note: Groups created via keypad will use the source that the keypad is set to, not what the field sets. Valid values are T, S1, S2, S3, S4, S5. ControllerGroupVolume Card R/W Set/get the volume for the group. If there is already a group, their volume will change. If there is no group, nothing will happen, but any subsequent groups created with ControllerGroup will set their volume to that specified this field. Note: Groups created via keypad will use the volume that the keypad is set to, not what this field is set to. Valid volume range is 00 – 79. Note: 00 is full volume. 79 is minimum volume. ControllerGroupZoneAddition Card W Add a zone to an existing group. The zone will be turned on, Its source will be set to the same as the other zones in the group, and its volume will be set to the value set by the ControllerGroupVolumeField. Valid values for the zone number are 01-18 ControlGroupZoneDeletion Card W Remove a zone from the group. The zones status will not change. Valid values for the zone number are 01-18 ControllerPowerOff Bool W Turn all zones all zones off. If Expansion Controllers are connected, their zones will also be turned off. Writing either true or false to this field will turn all zones off. ControllerTunerMode String W Values are AMB, FMB, FMM, FMS
AMB - Switch to the AM band without changing the frequency.
FMB - Switch to the FM band without changing the frequency.
FMM - Set FM mono mode.
FMS - Set FM stereo mode.The following fields are zone oriented. the xx value is 1 through 18, so there wil be 18 of each of these fields. ZxxFunction String W Similar to pressing a function on a keypad or remote. FF=fast forward, RW=rewind, PL=play, NE=next, TR=track, DI=disc; R-1 Remote only: OK=OK, UP=nav up, RI=nav right, DN=nav down, LE=nav left, GU=guide, ME=menu, EX=exit, IN=info. ZxxNumeric Card W Similar to pressing a numeric button on the remote keypad. Valid rage is 0 to 10. 10= the +10 button. ZxxPower Bool R/W Similar to pushing the power button on the remote keypad. This will power up/down the specified zone where a value of true will turn the zone on, false off. ZxxSource String R/W Similar to selecting a source on a remote keypad. Valid values are T, S1, S2, S3, S4, S5. ZxxReservedIR Card W Execute one of the 25 reserved IR commands. Valid range is 1 – 25. ZxxVolume Card R/W Set/get an absolute volume level in a C-6 zone. NOTE: yy number is in dB so 00 is the loudest at 0dB and 79 is the softest at -79dB. ZxxVolumeStep Bool W Increase or decrease the volume of a zone by one step (1dB). True increases volume, false decreases volume. Further explanation of the ControllerGroup field values of xxyyzz
The three values xx, yy, and zz in the command refer to the C6 (zones 1-6), the X-1(zones 7-12), and the X-2(zones 13-18) chassis respectively.
XX byte:
zone 1 2 3 4 5 6 weight 1 2 4 8 16 32To calculate the xx byte, add the weights together for the zones you want to be in the group. Example: to add zones 2, 3, and 5 to a group, Add their weights 2+4+16 = 22. xx now equals 22.
YY byte:
zone 7 8 9 10 11 12 weight 1 2 4 8 16 32To calculate the yy byte, add the weights together for the zones you want to be in the group. Example: to add zones 7, 10, and 11 to a group, Add their weights 1+8+16 = 25. xx now equals 25.
ZZ byte:
zone 13 14 15 16 17 18 weight 1 2 4 8 16 32To calculate the zz byte, add the weights together for the zones you want to be in the group. Example: to add zones 15, 17, and 18 to a group, Add their weights 4+16+32 = . xx now equals 52.
Now that xx, yy, and zz are calculated, you can add all these zones to a group by writing 222552 to the ControllerGroup field. You could also create a group by writing to the ControllerGroupZoneAddition field repeatedly, but it takes a lot longer to setup a group that way.
