DolbyCP Binding

This binding is intended to connect to a Dolby Digital Cinema Processor CP750. Support for CP950 may be added in future (if someone who owns one helps to test it).

It uses ASCII commands send over a TCP connection on port 61408. Please note that the CP750 only accepts up to 20 simultaneous connection and will discard the oldest connection if a 21st connection is established. So be sure to grateful shutdown each connection using the client's close() method, or it's AutoCloseable functionality.

This binding wraps the CP750 Java library from https://github.com/Cybso/cp750-java/ (opens new window).

This project is NOT affiliated with, funded, or in any way associated with Dolby Laboratories, Inc.

Supported Things

• cp750 - The Dolby Digital Cinema Processor CP750 Device.

Thing Configuration

Normally, only the hostname or IP address must be configured.

cp750 Thing Configuration

Name	Type	Description	Default	Required	Advanced
hostname	text	Hostname or IP address of the device	N/A	yes	no
port	integer	TCP port if different from 61408	61408	no	no
refreshInterval	integer	Interval the device is polled in seconds	5	no	no
reconnectInterval	integer	Interval a new connection is tried after IO error in seconds	10	no	no

Properties

Name	Description
osVersion	The operating system's version as returned by the device

Channels

These channels can be used to retrieve the current device state and change the controls.

The input mode can be either be controlled by the "input" string channel, or by writing an ON value to the dedicated switch channels, which represents the physical buttons on the CP750 device.

Channel	Type	Read/Write	Description
fader	Dimmer	RW	Fader value (0 to 100)
mute	Switch	RW	Mute (ON or OFF)
input	String	RW	Input channel as string (one of "analog", "dig_1", "dig_2", "dig_3", "dig_4", "non-sync" or "mic")
analog	Switch	RW	Is ON if input mode is 'analog'. When an ON command is retrieved, input mode will be changed to this channel.
dig1	Switch	RW	Is ON if input mode is 'dig_1'. When an ON command is retrieved, input mode will be changed to this channel.
dig2	Switch	RW	Is ON if input mode is 'dig_2'. When an ON command is retrieved, input mode will be changed to this channel.
dig3	Switch	RW	Is ON if input mode is 'dig_3'. When an ON command is retrieved, input mode will be changed to this channel.
dig4	Switch	RW	Is ON if input mode is 'dig_4'. When an ON command is retrieved, input mode will be changed to this channel.
nonsync	Switch	RW	Is ON if input mode is 'non-sync'. When an ON command is retrieved, input mode will be changed to this channel.
mic	Switch	RW	Is ON if input mode is 'mic'. When an ON command is retrieved, input mode will be changed to this channel.
