Help with Ruby Code

[gadget]

I am trying to create a device template for an Infocus IN74 projecter which is contolled via a serial cable.
I have adapted the Denon ruby code but it doesn't compile correctly.
There is also an error that Paritybit/Stopbit 8N1 NOT supported.

The commands to switch the device on/off are (PWR1) and (PWR0) inclusive of the brackets. Not sure if the brackets would be a problem.

Code:

You've missed a close bracket on line 49

Should be

if( !buf.nil? && (!buf.index("(PWR1)").nil? ))

to close that evaluation. The problem is it reads the rest of the code as part of that evaluation trying to find the close for the first bracket, doesn't find it, so cannot continue.
Also, I'm not at all familiar with Ruby, but you may have to escape the '(' and ')' in that string

if( !buf.nil? && (!buf.index("\(PWR1\)").nil? )) same for line 33....

in fact if line 33 is working, then you can probably remove a bracket from line 49, thus:

if( !buf.nil? && !buf.index("(PWR1)").nil? )

Note, still the question mark on the escaping issue.

Thanks for the quick response.

The missing close bracket has fixed the error, thank you.

I have fixed the partity error by changing from 8N1 -> N81.

I am now getting this error in the log

Failed Opening serial port: ttyS_54_0. <0xb4efdb90>
IOPool::handleStartup Open() failed <0xb4efdb90>

This is the serial port of the GC100 which is device 54.
How can i check what is causing this error.

Sorry, I don't have a GC100, I cannot test it.
I would, however, suggest that you use the Process Incoming Data routine rather than transmitting, waiting, then receiving in the same module.

basically, Ruby isn't threaded, so the faster you can return control, the better.
I'd use a global variable to track the command sent, and then when you receive data from process incoming data, you can compare the response to the command.

HTH,

I couldn't work out what the problem was, but have since deleted and re-created the device and am no longer getting the error.

Thanks

Please try not to re-create a device template!

Device Templates can not easily be deleted, and it makes check-in much more difficult.

I only deleted the AV-device and re-added it in from the same device template. I am in the process of creating some device templates for some of my equipment so will not delete them.
Hope to have a few to check in soon.

My device has stopped working now and I get the following error when the device initializes or when  i do a Messagesend.
