Page A-7 of the LANalyzer documentation lists various machines and speeds that the EXOS 225 and 325 boards are known to work at. As you can see, the older 225 board has many many limitations due to either 16 bit slots or higher than 6 Mhz bus speed. The T3200 runs with a 12 Mhz bus (although I've been told there is an undocumented BIOS call which will slow the CPU and the bus down to 6 Mhz), and the only full size slot is a 16 bit connector. I would doubt very much if the 225 will run in a T3200 at its full speed. On the other hand, if Excelan claims it will, then obviously you either have a bad board (they should replace it) or a bad Toshiba (they should replace it). If you had bought NGC's Sniffer Model 300, which includes the T3200 plus the full extra 3MB of expanded memory, fully supported, you wouldn't have integration problems like this. This is the reason we are not in the business of selling a board level product. (For a good laugh, try running stuff -- just about ANYTHING) in the recent IBM PS/2 Model 30/286. This is clearly the "PCjr" of AT-clones. It takes a special effort to make something so totally incompatible with existing AT cards, and I guess only IBM can afford to put the requisite number of engineers to the task! I think it must never have been tested with actual 16-bit cards with memory mapped buffers.
