The DSC/QSC-200/300 are configurable on-boards as either RS-422 or RS-485, and support speeds up to 921.6 Kbps. The adapters are mapped in one contiguous block of I/O space, and can communicate with two or four separate devices while utilizing a single interrupt. For performance in industrial settings, surge suppression and ESD-resistant driver/receivers are available.
Both come standard with 16550 UARTs and 16 byte FIFOs. Both are also available with optional 16750 UARTs and 64 byte FIFOs.
