Where can I find a schematic for a PCI-232/16 card?

[Farside]

I am looking for a Hardware schematic of the National Instruments PCI-232/16 channel card. I am placing 14 IrDA dongles on the Breakout box, and would like to know if it is possible via the PCI hardware to open multiple IRDA virtual ports at the same time?

Hello,
I cannot send you a schematic of our PCI-232/16, but I CAN tell you that multiple 232 ports on our serial cards can be opened simutaneously. They all work independently. If your IRDA software can open multiple ports, it will have no trouble doing so.

Ray:

I finally found a description of the PCI232/16 card. I was hoping it might have some memory buffering so that I could possibly cache a string of commands for each com port. Unfortunately, each port only has a 64 byte buffer so what I wanted to do is not feasible. Just for reference though, does NI make any Serial mux ports that would provide individual buffer caches on the order of 8K+ ?

Regards,

Farside,
NI does not make ports with larger individual buffer caches, but you are not limited to 64 bytes in software memory. If you want, you can even write information directly from a file with the VISA Write from File.VI
