BAB 740
1—3
An Ethernet controller for either 10 Mbps or 100 Mbps Ethernet with
PCI DMA capabilities is provided on-board. Front panel interface is
10/100BaseT.
The last interface on the local PCI bus is the ISA bridge (Winbond
W83C553), interfacing to the internal ISA bus with additional on-
board components. Additionally, there are the standard PC
components real-time clock, keyboard controller, dual serial I/O and
parallel controller.
1.2.4 VMEbus Interface
The VMEbus interface uses the Universe II bridge controller,
connecting the internal PCI bus and the external VMEbus. It
supports 8-, 16-, and 32-bit data transfers in master and slave mode.
Additionally, bus controller (arbiter) functionality is available.
Use of the BAB 740 without VMEbus is possible; only power must
be supplied through VME connectors.
1.2.5 Mechanical
The board format is double Eurocard (6HU) using two VMEbus
slots. The VMEbus connectors are mounted at the position of the
second VMEbus slot (the slot on the right) of the two slots the board
is using. Two slots for single-size PMC modules are available.
1.2.6 I/O
8-bit SCSI is routed over the VME P2 connector. Additionally, the
serial I/O channels 2 .... 4 and the parallel I/O are also routed via P2.
On the front panel the Ethernet 10BaseT connector is located as well
as the separate front panel for PMC I/O signals. The keyboard
connector and two serial RS232 channel are also routed to the front
panel (9-pin D connector).
