AMX DUET PJLINK MODULE

duet-lib-pjlink

This library contains the code for NetLinx or Duet projects to interface with video projectors that implement the PJLink protocol over TCP/IP. This class adheres to the Java 1.4ME API to maintain compatibility with AMX Duet devices.

Overview

Issues, Bugs, Feature Requests

Any bugs and feature requests should be reported on the GitHub issue tracker:

https://github.com/amclain/duet-lib-pjlink/issues

Pull requests are preferred via GitHub.

Mercurial users can use Hg-Git to interact with
GitHub repositories.

Known Issues

  • The NetLinx pulse keyword can trigger the on/off channel events in a way that
    doesn't get passed to the Duet module. Therefore on and off should be used.
    Wrapping the call to off in a 1 second wait time seems to be a valid workaround.

  • Error status channels may not work correctly.

Examples

Channel Numbers

The full list of channel numbers can be found in the file PJLinkModule.java
