Controlling VTG700 via RS232

[smoken]

I want to control an instrument via RS 232 using Labview, by the way VTG700 is a video transmission generator. I want to control this equipment via RS232 using Labview, basically once application should tell the generator to change channel, patterns and thus an output to the RF out. Or adjust some RF signal level to like 100dBuV. Can anyone tell where should I start? the Setting for the VTG is defined or already set and using a null modem cable RS-232. A sample vi and sample code is appreciated.

Thank you all in advance..

I searched on google for that instrument but I couldn't find any information apart from the manufacturer which is Grundig. So it might be tough to find someone who has written an application already but you never know. I would suggest that you think about writing your own application using VISA Write and Read.

If you have access to a programming manual you could start your application based on one of the serial examples shipped with labview. To get to them goto Help menu then select Find Examples, click the Search tab and enter SERIAL into the keyword area. I would start with Basic Serial Write and Read.vi. You will need to know the serial tranmission parameters such as Baud Rate, No Of Data Bits, Start/Stop and Parity.

If you have another application that controls the instrument over RS232 you could use Portmon from http://www.sysinternals.com/utilities/portmon.html to monitor the data bytes which you could then use in your own application using VISA Write.

Trying to get you started ...
