The issue as documented by the HAI folks related to an overly promiscuous network port.
A wanted feature many years ago but not so much today; if that makes any sense?
Try putting a router between the OPII network interface and the rest of the network and update to most current firmware (3.14X).
Worked for me.
Initially here did just disconnected the network interface (losing touchscreen access except for the older Omnitouch screens) and it fixed my issues.
Today have a modded microrouter in place using the panel's power supply.
I have no issues with my serially connected devices (including the Omnitouch 5.7 legacy devices) and IP connected devices (Omnitouch 5.7e's et al). (well other than some gotchas relating to a firmware update which deleted some features that used to be there for the old stuff for the new stuff (Omnitouch 7/ Email board wiped some older firmware stuff in a willy nilly like manner); and personally here didn't use it much anyways.
