Introduction
Xtreme/104 adapters are high performance multi-port serial adapters in a PC/104 form factor that
enable you to connect up to 8 serial devices to your PC-based system. They provide a high speed
interface between your host computer and multiple external serial devices
Features
●
4 or 8 asynchronous serial ports.
●
Hardware configurable RS-232 and RS-422/485 electrical interfaces. The interfaces are
jumper selectable for each port. (Xtreme/104 RS-232 adapters have an RS-232 only
electrical interface.)
●
Multiple Xtreme/104; Xtreme/104 RS-232 adapters may reside in a system.
●
16C654 quad UARTs control each port. The 16C654 quad UART has 64 byte TxD and
RxD FIFO buffers for each port and automatic software/hardware flow control.
●
Each port has independent baud rate selection offering baud rates from 50 – 230.4 Kbps
(RS-232) and 50 – 460.8 Kbps (RS-422/485), with 5, 6, 7 or 8 data bits and 1, 1.5, 2 stop
bits, odd or even parity.
●
On board jumpers allow the selection of 8 predefined I/O address sets.
