How Many Devices Can I Communicate With Using RS-485 Serial Products?

Hardware: Serial>>RS-485

Problem:
I have a National Instruments RS-485 serial product (PCI-485, PCMCIA-485, ENET-485, etc) and I am wondering how many instruments I can communicate with at the same time?

Solution:
The product pages for these products state that they "communicate with up to 31 devices." This number is per port so if your serial product has 4 ports, you can communicate with 124 devices connected at full load.
