Fancy Power Feedback

Chad Reynoldson — Thu, 30 Jul 2009 18:54:15 GMT

Here are a couple of fancy feedback statements for projector on and off buttons:

(*-- PROJECTOR --------------------------------------------*)
  [dvPNL,211] =([dvPROJ1,127] && ![dvPROJ1,227]) || ([dvPROJ1,227] && nFlash)
  [dvPNL,212] =([dvPROJ1,128] && ![dvPROJ1,228]) || ([dvPROJ1,228] && nFlash)

If you can’t tell by looking at it, I use channels 127/128 for on/off state. Channels 227/228 are used for the transition to on/off state (warming and cooling). For the record, channels 27/28 are used for execution.

Of course, you need to toggle nFlash in mainline (yes mainline) like this:

WAIT 5 nFlash = !nFlash

IF(dvDEV.PORT)

I’m running into more and more IP controlled devices in the AMX world of control. I have gotten into a habit of checking if a DEV variable has a value with IF(dvDEV) and it has worked all these years for the various devices (232, IR, relay).

With IP devices, this always evaluates to false. It seems to me that IF(dvDEV) is actually evaluating as IF(dvDEV.NUMBER) and with the case of IP devices is 0 (false).

I am now changing to IF(dvDEV.PORT) so that all conditions will play nicely for IP, 232, IR, and relay devices.

Jaadu VNC

I had recently heard of the Jaadu VNC viewer app for the iPhone/iTouch and I wanted to give it a try. It is an iPhone application that provides a VNC client, allowing you to view the screen of an AMX touch panel directly on your iPhone. It was designed with “AMX Touch Interface” in mind using AMX G4 Web Control.

Adding an entry to a touch panel is very simple. First, select “Manual” on the bottom. Next, click “+” on the top. Next, enter the entries name, ip address (stick with port 5900), security password (if any), and select “AMX Touch Interface” as the computer type. Finally click “save server” and your done, with a new entry on the manual connection list.

I tried it with both a 4×3 and 16×9 touch panel. With both panels, it turned the view 90 degrees into landscape view. With the 4×3 panel, the image was centered on the screen with black bars on either side (no scaling). With the 16×9 panel, the image was centered and filled most of the screen. I’ll be curious to see how AMX’s new NXV-300 will work, specifically at the 480×272 resolution.

The viewer also has built-in keyboard control that will also generate keyboard presses on native AMX keyboard and keypad popups (AKB and AKP). The keyboard popups on the screen were pretty small to get an accurate touch, so it was good to see that work. The only keyboard exception is that I could not get capital letters (ABC) to work. All other keys worked fine.

I’d say that for the small price ($24.99), it is a steal and fits a need. Plus there’s no additional netlinx programming required.

Tandberg MXP with TVS

Chad Reynoldson — Tue, 07 Jul 2009 13:48:48 GMT

I had recently programmed an AMX control system that controlled a Tandberg 6000MXP codec that utilized an external camera switcher, the Tandberg TVS. It took some time to make it work and here is what I learned.

Switching the camera input requires two separate commands. First, you switch the TVS using the “xconfiguration Switch Source: <1-6>“ command. Then you need to switch the MXP to it’s main video source using the “vidin 1” command.

Now when controlling the selected TVS camera, you need to use camera values 8-13 like this: “xcommand cameramove camera:<8-13> direction:“.
