Hi guys,
Thanks a lot,
Dyaker, the Operative system to use hasn’t been decided yet, let me know which one is preferable and fast enough for our needs and I´ll get it for the project, PC, Unix, etc. And If you have recomendations on the machine itself please let me know too.
On the beginning someone suggest me to use an Embedded system Platform such us the RabbitCore line from Rabbit Microprocessors instead of a embedded Computer for video processing, because this systems generally contain no moving parts, give off little heat, requiere little electricity and can withstand extreme temperatures. This specific system works with Dynamic C. But pretty soon we went back to the embedded Computer due to the complexity of the tasks to perform, and most likely the Computer will be located in a temperature-controlled room inside the building anyway, so working temperature won’t be an issue.
Also a pc-based system will be easier to troubleshoot than a complex microprocessor. Ideally we want to remotely monitor the functioning of the system via web, and this will be much easier to do if using a computer.
For the RS485 card what about this one? Comtrol RocketPort INFINITY Quadcable DB9M, RS485 serial port expansion card

Rob, I´m pretty sure it takes gerber files, I´ll double check with the technician and let you know soon.
The Machine is a Torchmate CNC personal milling machine 4’x8’, but I’ll get the exact Specs. I’m adding a couple of images of circuits made by this model of milling machine.
It´ll be great if you can send me the sample layout to try !!!
Thanks a lot
just one question regarding the power supplies.
I’m thinking that whatever we install directly on the panels should be pretty tough, since this will be outside. Although it won’t be exposed to direct sunlight since all the electronics will be protected from the sun on the back of the panels and enclosed on a water-resistant case. I’m trying to come with a pivoting system to install the panels on the Ventilated curtain wall aluminum frame (some kind of hinge-based system that would allow us to easily access the back of the panels for repairing just by turning it open), but I’m afraid that this will be too expensive, so structural silicon will be used instead. This means that every time you need to access the electronics on the back of any panel you’ll have to remove it from the screen and take it down.
Regarding the PICs, shift registers, Triacs, etc. I guess we have no choice, but, if we end using the structural silicon, do you think we should install the power supplies somewhere else? may be on the bottom of the screen? How durable do you guys think they are?
As I write this lines I realize how important is to have a hinged system or an easy access method to the electronics of the screen though.
Thanks a lot!!!
