Facility Control

Trying to control a Contigo 2 lighting console that really only accepts Telnet commands. I've seem some discussion here on controlling a BM Videohub using TelNet but I'm unfortunately a little lost. Unlike UDP/TCP my understanding is that Telnet has some negotiation that needs to be done to open a session, how could this be done? Here's an example API command that just sets a fixtures intensity to 100%

API.SetLevel('2','100')

Thanks in advance!

I guess I can also do this through applescript with terminal, but how can you execute an applescript via dashboard?
#DashBoard

Frequently, a 'telnet command' interface is simply a raw socket connection and you can just fire the command with rosstalk.sendMessage(HOST, PORT, MESSAGE);

If the device requires a username/password, you may be able to use rosstalk.sendMessage(HOST, PORT, 'USERNAME\r\nPASSWORD\r\nMESSAGE\r\n');

If you did want to use AppleScript, you'd need to run the DashBoard panel on your Mac. Here is an example panel that we have shared in the past for people trying to achieve this:

<abs contexttype="opengear" style="">
   <meta>
      <api>function runAppleScript(applescriptCommand)
{
   var runtime = java.lang.Runtime.getRuntime();
   var args = ["osascript", "-e", applescriptCommand];
   var process = runtime.exec(args);
}
</api>
   </meta>
   <button buttontype="push" height="162" left="22" name="Run Apple Script (for iTunes)" top="21" width="304">
      <task tasktype="ogscript">var applescriptCommand =  "tell app \"iTunes\"\n" + 
                            "activate\n" +
                            "set sound volume to 80\n" + 
                            "set EQ enabled to true\n" +
                            "play\n" +
                          "end tell";

runAppleScript(applescriptCommand);
</task>
   </button>
</abs>

#DashBoard

Thanks James, No username/password so we should be good there. I've tried the rosstalk with the host port message as follows

rosstalk.sendMessage('10.45.13.181', 11123, 'API.SetLevel('2','100')');

but I haven't gotten it to work, is there something glaringly obvious I'm missing here?
#DashBoard

Figured it out! have to change parenthesis to slashes....
#DashBoard

Your other option would be to use double quotes:
rosstalk.sendMessage("10.45.13.181", 11123, "API.SetLevel('2','100')");
#DashBoard
