Projector Remote Control
The Projector Manager allows you to remotely control a network-connected projector that conforms to the Japan Business Machine and Information System Association (JBMIA) PJLink specification. Available in OpenLP v2.2.
Projector Settings
The available projector options can be changed using the main settings menu by going to Settings -> Configure OpenLP -> Projectors tab.
The options available are:
Connect to projectors on startup : Check if you want to attempt to connect to all projectors when OpenLP starts
Socket timeout (seconds): Time in seconds to wait for the projector connection. Available options are 2 to 10 seconds.
Poll timeout (seconds): How often to poll the projector for status information. Available options are 2 to 60 seconds. NOTE: PJLink specifications call for automatic disconnect after 30 seconds of inactivity.
Source select dialog interface: Select whether you want all video source options on one dialog page or to use tabs to consolidate the inputs based on video group.
Once you are satisfied with the settings, click on the "OK" button, otherwise click on the "Cancel" button to ignore changes and close the dialog.

Adding a Projector
To add a new projector, click on the "Add new projector" icon on the Projector Manager tab bar. You will be given an input dialog box like the below image.
The required information are "IP Address", "Port Number", and "Name" entries. The port number is already set with the default PJLink port.
The "PIN" entry is only needed if the projector you are connecting to has the PJLink PIN set. Be careful, since most projectors have a separate entry for the PJLink PIN, any other network PIN or password, as well as a separate entry for any HTML access name/password settings (if the projector has HTML webpage access). The PIN setting here is ONLY used if the projector has a "PJLink access code" or "PJLink PIN" setting.
Once you are done entering the new information, click on "Save" to save the entry and add it to the projector manager list. Congratulations, you now have your first projector entry in the list and ready for control.
When you have multiple projector entries selected, the projector manager toolbar will change to the following:
