# 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.
