Does anyone know of any PCI cards that have LVDS ports? I have a requirment to communicate between 2 PC's over a point to point connection at 33Mbps. Other then LVDS what comm protocal supports these speeds? (I know USB does, but I have not found a USB hosthost bridge that supports those speeds.)
If the answer was useful I'm sure I could have done something with it.
I'd rather not. I'd rather keep this as simiple as communicating over a serial port on a RS-232 cable
The system I am buiding will be running On Time's RTOS-32 OS. I also have to build a host emulator that will talk to my system. For that I can use anything I want, and I was hoping to use Linux (but if I had to use Windows I would).
What about serial ports and parallel ports?
Again, I ask: how can I use ethernet for direct point to point communication between 2 computers?
ethernet does not need anything else than point to point...no switches or routers of whatever kind. but: the transition from point2point to a true network is "for free"...and this is exactely one of the strong points speaking *in favour* of ethernet/ip.
when it comes to the *protocol* to be used i would strongly recommend:
-on top of it: tcp or udp, depending on your detailed requirements
-also, think about using a true application protocol on top of tcp.
what using tcp/ip, delivery of data is guaranteed. this is not necessarily the case when using plain serial point2point. also: from my (subjective, of course) point of view the real hard stuff is designing a meaninful, stable application protocol...and this you have to do no matter if you work "serial" or "ip".
For the software on the server computer create a socket and get it to listen to a port. The client then requests a connection to be made. The server accepts the connection. Then write all the data that you want. This link
tells you everything that you need to get started.
Sorry. The common mode voltage range of LVDS is in the order of less than one volt. Meaning, the GND of the innvolved card require to be within less than 1 Volt. This means you have to take the chassis potential with a thicker cable.
