8 SP - 8 Port Serial SBus Multiplexor [MAGMA]

MAGMA 8 SP - 8 Port Serial SBus Multiplexor: The MAGMA 8 SP is an SBusexpansion board that has eight high speed asynchronous serial ports withfull modem control. It can be used to connect to ISDN TerminalAdapters, modems, terminals, printers/plotters or any other RS-232device. It is fully compatible with Sun Microsystem's(TM) SPARC(R)computers and other computers compliant with SPARC(R) International SBusspecifications. Serial Port Hardware: The MAGMA 8 SP is a single widthSBus board based on the Cirrus Logic CD-1400 Serial/ParallelAsynchronous Communications Engine, a RISC I/O processor capable ofcontrolling four serial ports. The CD-1400 has many advanced featureswhich minimize CPU overhead, the most important include: Each port'stransmitter and receiver has it's own 12 byte FIFO buffer which minimizesthe number of interrupts the CPU must service. Flow control is handledautomatically by the CD-1400, without intervention by the CPU. Two CD-1400s are used on the MAGMA 8 SP. Several Magma Sp boards can beconfigured in a system. The driver is optimized to reduce CPUutilization and treats all of the Magma Sp boards in the system as asingle device. Multiple service requests can be handled in a single passthrough the driver. Software: The MAGMA 8 SP device driver is designedto take advantage of the board's high speed serial capabilities. Thedriver is compatible with Solaris(R) 2.x and SunOS(TM) 4.1+ and supportsall features of both systems. It is delivered on a 3.5" diskette andfeatures "plug and play" installation. FEATURES: Number of ports = 8Asynchronous serial ports Maximum speed = 128Kbps on each port Physicalconfiguration = Breakout box with 8 RJ-45 connectors ElectronicInterface = RS-232 Flow control logic = Fully automatic XON/XOFF and/orRTS/CTS Data word size = Any size from 5 to 8 bits Number of stop bits= Either one or two Modem control signals = RTS, CTS, DTR, DSR and CD.
