Why do we need Rs485 adapter?

[Zangief1977]

Why do we need the rs485 adapter when it's already built on to the Sequent board? Is it because of Bluetooth? We don't use BT right? Thanks

If you can get the Sequent rs485 working, then you don't need another one. But often they conflict with some of the GPIO pins or don't operate the pass-through properly or go bad. When that happens, having a separate port is the answer.
