I am trying to use 4 Rocketport octa-cable PCIe cards in a single PC. Data is incoming at ~3800 bytes/sec on each of the ports. With only 2 cards installed (16 ports) all is well, but with 4 cards installed (32 ports), I get checksum errors on the acquired serial data on some of the ports. The ports that have errors change from test to test. The PC CPU usage is low and there is no evidence that bytes are being missed or dropped, just that they are not being received as transmitted. All ports are RS232 at 115 kbaud.
Any ideas or anyone run into similar issues?
