C# Class rv.PJLinkConnection

Simple class to control networked projectors via the PJLink protocol. See full spec here: http://pjlink.jbmia.or.jp/english/data/PJLink%20Specifications100.pdf This library was written in one day, so don't expect perfection. Most information must be fetched from commands after execution (sendCommand). For most common tasks, there are some shortcuts available in the PJLinkConnectionPJLinkConnection class. Basic usage:

  // Create connection object, communicating with projector with IP 192.168.1.14 // Projector has authentication enabled, password is rv (ignored if auth disabled) PJLinkConnection c = new PJLinkConnection("192.168.1.14", "rv"); //using shortcuts c.turnOn();  c.turnOff();  System.Console.WriteLine(c.getProjectorInfo()); //using low(er) level commands ErrorStatusCommand esc = new ErrorStatusCommand(); if (c.sendCommand(esc) == Command.Response.SUCCESS)             Console.WriteLine(esc.dumpToString());             else Console.WriteLine("Communication Error");
