The BBG-8000 is a
multiprocessor based, 6U VMEbus format serial protocol
converter. It will operate in a VMEbus backplane or in a
stand alone mode requiring only a +5 volt DC power supply.
The BBG-8000 is designed to operate with an eight channel
RS-232 serial multiplexor. It provides interfacing to four
channels of RS-232, one channel of synchronous
MIL-STD-188-114, two channels of RS-422, and one channel of
16 bit discretes. The four channels of RS-232
conversion support hardware handshaking signals RTS, CTS,
DCD, and DTR as well as full duplex signals TXD and RXD.
The asynchronous RS-232 to synchronous MIL-STD-188-114
supports hardware handshaking signals RTS and CTS as well as
simplex signals TXD and RXD, and clock signals TXCLK and
RXCLK. The TXD and RXD signals have 32 KBit FIFO memory
buffers controlled by the respective TXCLK and RXCLK
allowing synchronous baud rates of several megabits per
second.
The two channels of RS-422 conversion supports hardware
handshaking signals RTS, CTS, DCD, and DTR as well as full
duplex signals TXD and RXD.
The 12 bit discrete parallel to RS-232 conversion supports
TTL level input signals and is factory programmable for user
required serial data streams. Serial baud rates are switch
selectable for 1200, 2400, 4800, 9600, and 19,200 bits per
second.
