SYNTAX ERROR IN GSD, SERIAL TO DMX 512 CONVERTER

[gonesurfing]

 Hi,
I bought a simple serial to DMX 512 converter and I am have troubles with the ruby and would be grateful if someone could help as I have exhausted my technical abilities which are very basic.  I was copying "GSD to driver weeder I/O WTDIO-M". I modified the AHA to the instructions from Milford Instruments ie channel number channel level [34,127]. Could you please view the error log and point me in the right direction?  If I can get this simple DMX converter working I will post a how to in the wiki.  I am sure there are a lot of better ways to write the driver in ruby but you have to start somewhere and this seemed to be the easiest to follow.  I have deleted the log from child 47 to child 86 as it just repeated.  I did this to cut the size of the post down.

what are lines 7 and 13 used for? They look like pronto infrared codes or something like that..

br Hari

[tschak909]

it looks like there was a collision with an existing entry in the ir repository... ugh.

What do you need command 192 and 193 to do? Is there commands for the DMX box to turn it on or off?

Start with deleting the code in those for now as that is where your syntax error is.


I think that your receiveCommandForChild can be simplified dramatically.

def cmd_ReceiveCommandForChild(cmd)
  id=device_.childdevices_[cmd.devidto_].devdata_[12]#get child device number
  if cmd.id_==192#192 is on
        conn_.send(id + ",240\r")#set channel ID to 95%
  end
  if cmd.id_==193#193 is off
        conn_.send(id + ",0\r")#set channel ID off
  end
end

Hi,
Many thanks for your replies - especially for the heads up on the ruby code.  I knew it could be done but I just didn't know how.  I guess I need to explain a little more about my set-up.  The serial to DMX converter will handle 112 channels of DMX.  I am only currently using 37 channels.  I set-up a template device 46 as a lighting interface.  I then created 37 child device templates which were lighting environment templates light switch on/off which gave me the command 192/193.  I guess I have messed something up with the templates.  My plan now is to delete the templates and reinstall with the amended ruby.  Once again many thanks for your assistance.  Steve

[darrenmason]

Hi Steve,

You should only need one device template created - which is for your lighting interface.
Your child devices should just be the light devices that already exist. Basically what you are doing is handling commands for these devices in the interface.
From the looks of your interface it should support dimming commands as well quite easily.

Out of interest what is the converter you are using. I might look at getting one myself for controlling some LED lighting.

Regards
Darren

Hi Darren,
Thanks for your help.  I have seen the dimming commands #184 I presume this is the one you are on about.  I understand that you set the level to 50% or in my case with the converter to 127.  However, I do not understand how to programme the ruby to set up and down from the mid point.  I was planning to get a simple on/off working before I looked further into the dimming as ultimately this is where I would like to go. 
I am by no means an expert on LEDs and DMX lighting however I have put a considerable amount of time in research.  When it comes to LED lights I use two types - one is a concealed unit eg a par or a wash light generally they have 150 LEDs and are 50 watts in red, green and blue.  They work great and you use one channel for one colour simply by dimming the channels you end up mixing the colours and the fourth channel to turn on/off.  The second method I use is a DMX decoder which I then attach strip LEDs or ribbons.
I prefer using the SMD LEDs as opposed to the single colour LEDS as if you are running red, green, blue you have to diffuse them because they do not look great if the bulbs are visible.
I have attached a couple of web pages with the suppliers of the converters they also have some other reasonably priced stuff.  The converters are slightly restrictive when setting up your LEDs you would be better off with some sort of control interface.  I like the look of this one and there is also some free software - one of which is a web server which will handle HTTP and has a lot more channels than one of the converters and it can also run as lighting desk on a pc which there is also free software.  But wait it gets even better - there is a partly compatible DIY project I think it needs some programming to finish it off.  I will also include their website and the website where the software is.
If you send me an address I have some spare SMD LEDs, a DMX decoder and a RF decoder.  I also have a half complete DIY kit which I am happy to give to you if you (its not been started ,i have not sourced all the parts,i just dont have the time)
