Hi Dozo,
Yes the trx looks fine - if it works then I'd leave it as it is. The baud rate is a little slow; 4800. You could double it - 9600 but i doubt you'd notice a significant different.
If you do want to double the baud you need to make sure to set the corresponding machine parameter...
Dear Dozo,
V12 is not strictly speaking Windows 7 compatible - this may be the reason why MetalDesigner will not function. What errors do you get during installation?
Have you been able to establish connection to the Alpha? Are you drip feeding; if so what cable config are you using and DNC5...
