ioBroker.PJLinkV2

Tests:

This adapter controls any PJLink compatible projector or display with ioBroker.

PJLink is a unified standard for operating and controlling data projectors and displays. The protocol enables central control of certain devices, manufactured by different vendors. The protocol is used by NEC, Casio, Seiko, Sony, Panasonic, Hitachi, Mitsubishi, Ricoh, Vivitek and even more. Please consult the device manual to check compatibility.

Note: Devices are not sending information activly... therefore, the adapter will pull certain information frequently (see polling interval). Do not reduce the polling interval <10 sec. because the device needs up to 2 sec. to answer and the script will query several paramters!

Current shortcomings

• Audio / Video mute can not be set. Setting these modes is not working correctly right now. It's disabled in the code - can somebody contribute on this?
• Warum-Up and Cool-Down ist not tested because my device is to giving these information - can somebody contribute on this?
• All dialogs are in English as for now, DE and RU are in progress. Further translations on demand.

ToDo

• Implementing table into admin interface to translate source port ID to port name (like 31 = HDMI1)
• Supporting PJLink Class 2 protocol

How the adapter works

The adapter consists by three elements:

• Admin interface to define device specific parameters (admin/index.html)
• JavaScript module for device communication, based on PJLink protocol (utils/pjlink.js)
• Main script (main.js)

The Main script works in four steps:

1. Doing some initial configuration like creating ioBroker objects
2. Starring the first communication with the device and asking for the current parameters
3. Waiting for a state change like switching the input source or turning power off
4. Executing the change with the device Please be aware, that the communication with the projector is not possible if the projector is in standby with power saving feature enabled. Therefore, it will not be possible to turn the project on using this adapter. To do so, disable the power saving feature using the projector configuration (Menu > Settings...).
