# Monoprice Whole House Audio Binding
This binding can be used to control the following types of whole house multi-zone amplifier systems:
- Monoprice MPR-SG6Z (10761), Monoprice Passive Matrix (39261), Dayton Audio DAX66 or compatible clones
- Monoprice 31028 or OSD Audio PAM1270 **(untested)**
- Dayton Audio DAX88 **(untested)**
- Xantech MRC88, MX88, MRAUDIO8X8 or CM8X8 **(untested)**
The binding supports two different kinds of connections:
- serial port connection
- serial over IP connection
For users without a serial port on the server side, you can use a USB to serial adapter.
You don't need to have your whole house amplifier device directly connected to your openHAB server.
Some newer versions of the amplifier have a built-in Ethernet port that supports serial over IP.
Or you can connect it for example to a Raspberry Pi and use [ser2net Linux tool](https://sourceforge.net/projects/ser2net/) to make the serial connection available on the LAN (serial over IP).
## Supported Things
Monoprice 10761 & 39261 or Dayton Audio DAX66 amplifiers use the `amplifier` thing id. Up to 18 zones with 3 linked amps and 6 source inputs are supported.
Note: Compatible clones (including 4 zone versions) from McLELLAND, Factor, Soundavo, etc. should work as well.
***The following three thing types were implemented via available documentation only and have not been tested. Please open an issue for any bugs found when using these thing types.***
Monoprice 31028 or OSD Audio PAM1270 70 volt amplifiers use the `monoprice70` thing id. 6 zones per amp (not linkable) and 2 source inputs are supported.
Dayton Audio DAX88 amplifiers use the `dax88` thing id. 8 zones (2 un-amplified) per amp (not linkable) and 8 source inputs are supported.
Xantech MRC88, MX88, MRAUDIO8X8 or CM8X8 amplifiers use the `xantech` thing id. Up to 16 zones with 2 linked amps and 8 source inputs are supported.
Some Xantech amps provide unsolicited zone updates for keypad actions and may work with the `disableKeypadPolling` option set to true which will prevent un-necessary polling of the amplifier.
Note: MRC44 amps do not support serial control.
## Discovery
Discovery is not supported.
You have to add all things manually.
## Thing Configuration
The thing has the following configuration parameters (number of sources and zones is amplifier dependent):
| Parameter Label | Parameter ID | Description | Accepted values |
|------------------------|----------------------|--------------------------------------------------------------------------------------------------------------------------------|------------------|
| Serial Port | serialPort | Serial port to use for connecting to the whole house amplifier device | Serial port name |
| Address | host | Host name or IP address of the amplifier or serial over IP device | Host name or IP |
| Port | port | Communication port (8080 for newer amps with built-in serial over IP) | TCP port number |
| Number of Zones | numZones | (Optional) Number of amplifier zones to utilize in the binding (See Supported Things for max number of zones per Thing type) | 1-18; default 6 |
| Polling Interval | pollingInterval | (Optional) Configures how often (in seconds) to poll the amplifier to check for zone updates | 5-60; default 15 |
| Ignore Zones | ignoreZones | (Optional) A comma separated list of Zone numbers that will ignore the 'All Zone' (except All Off) commands | ie: "1,6,10" |
| Initial All Volume | initialAllVolume | (Optional) When 'All' zones are activated, the volume will reset to this value to prevent excessive blaring of sound ;) | 1-30; default 10 |
| Source 1 Input Label | inputLabel1 | (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 1") | A free text name |
| Source 2 Input Label | inputLabel2 | (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 2") | A free text name |
| Source 3 Input Label | inputLabel3 | (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 3") | A free text name |
| Source 4 Input Label | inputLabel4 | (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 4") | A free text name |
| Source 5 Input Label | inputLabel5 | (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 5") | A free text name |
| Source 6 Input Label | inputLabel6 | (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 6") | A free text name |
| Source 7 Input Label | inputLabel7 | (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 7") | A free text name |
| Source 8 Input Label | inputLabel8 | (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 8") | A free text name |
| Disable Keypad Polling | disableKeypadPolling | Set to **true** if physical keypads are not used so the binding will not needlessly poll the amplifier zones for changes | true or false |
Some notes:
- On the 10761/DAX66 amp, activating the 'Page All Zones' feature can only be done through the +12v trigger input on the back of the amplifier.
- On Linux, you may get an error stating the serial port cannot be opened when the MonopriceAudio binding tries to load.
- You can get around this by adding the `openhab` user to the `dialout` group like this: `usermod -a -G dialout openhab`.
- Also on Linux you may have issues with the USB if using two serial USB devices e.g. MonopriceAudio and RFXcom.
- See the [general documentation about serial port configuration](/docs/administration/serial.html) for more on symlinking the USB ports.
- Here is an example of ser2net.conf (for ser2net version < 4) you can use to share your serial port /dev/ttyUSB0 on IP port 8080 using [ser2net Linux tool](https://sourceforge.net/projects/ser2net/):
```text
8080:raw:0:/dev/ttyUSB0:9600 8DATABITS NONE 1STOPBIT LOCAL
```
- Here is an example of ser2net.yaml (for ser2net version >= 4) you can use to share your serial port /dev/ttyUSB0 on IP port 8080 using [ser2net Linux tool](https://sourceforge.net/projects/ser2net/):
```yaml
connection: &conMono
accepter: tcp,8080
enable: on
options:
kickolduser: true
connector: serialdev,
/dev/ttyUSB0,
9600n81,local
```
