Summary:
Question: The PCXi Digiboard documentation supplied from Digiboard shows that multiple boards can be configured at the same physical address. Citect does not seem to support this setup? Can I use the drivers supplied with the Digiboard to use this feature? 

Solution:
Citect does not support multiple PCXi Digiboards at the same physical address. We have found that this is unreliable in the way that Citect interfaces to the board. You can use the Digiboard drivers supplied with the board, however they will give lower performance than the Citect drivers. You can try both drivers and test to see exactly how much performance you loose. You should test the performance using a fully configured system as Citects drivers will perform best under high loading conditions.

If you use the drivers supplied with the Digiboard, Citect will see the ports as normal COM ports. So configure the ports as you would the local COM ports.
