WARNING !
This equipment generates and can radiate radio frequencies. If not installed in accordance with the instruction manual, it may
cause interference to radio communications. The equipment has not been tested for compliance with the limits for class A
computing devices, pursuant to subpart J of part 15 of FCC rules, which are designed to provide reasonable protection against
such interference, but temporary usage is permitted as per regulations. Operation of this equipment in a residential area is
likely to cause interference, in which case the user, at his own expense is required to take whatever measures may be required
to shield the interference.

1.2 General Description
Figure1: Block Diagram
The BAB-430 is graphic module for the BAB-40/60 CPU boards. It
features the connection of video monitors and flatpanel displays. The
BAB-431/433/434 flatpanel display adapter has to be mounted on top of
the BAB-430. The display adapter enables the flatpanel mode
simultaneous to the video mode. So the BAB-40/60 is ideal suited for
applications where the support of both display types video monitors and
flatpanel displays is required. This is helpful especially for adjustment or
service functions.
With the standard graphic interface BAB-430 installed the BAB-40/60
still needs only one VMEbus slot. Only if the display adapter
BAB-431/433/434 is used the BAB-40/60 occupies two VMEbus slots.

1.3 Technical Details
The BAB Universal Graphic Module consists of the following building
blocks:
•Keyboard Controller
•65548 High Performance Flatpanel / CRT GUI Accelerator
•1MB DRAM
•DAC for Contrast Control
•Display Adapter
1.3.1 Keyboard
Controller The BAB-430 uses a standard 82C42 keyboard controller with Phoenix MultiKey/42 firmware to interface to a PS/2 compatible keyboard. After
being properly initialized by the RMon firmware of the BAB-40/60 it is
able to communicate with the keyboard via a 6-pin Mini-DIN connector.
All keyboard signals are equipped with protection devices to improve
ESD and EMC characteristics. The 82C42 is clocked with one quarter of
BLCK (which is the bus clock of the BAB-40/60 board).
1.3.2 65548 High
Performance
Flatpanel /
CRT GUI
Accelerator
The BAB-430 uses the VLB mode of the 65548. The BGB signals are
translated by a MACH210 device to the VLB signals. Since the 65548
uses Intel byte ordering in VLB mode the data bus bytes are connected in
reversed order to the BGB. This results in correct ordering for accessing
the framebuffer and the 8-bit wide registers of the 65548. For accessing
the 32-bit registers of the 65548 the bytes in the longword must be
swapped. The 65548 is able to generate timing signals for virtually all
flatpanel displays and for CRT displays up to 80MHz dotclock.
1.3.3 1MB DRAM 1MB of DRAM is used to hold the framebuffer for up to 1024 x 767
resolution with 8bit/pixel. Due to the linear addressing feature of the
65548 the framebuffer appears to the CPU as a single plane as it is
required by most graphic software. The DRAM is also used by the 65548
to temporary hold data that is required for dualscan displays. The 32-bit
data path to the BGB offers a memory bandwidth of about 9MB per
second. To improve graphic performance the BitBLT engine of the 65548
can be used. Since the 65548 has direct access to the DRAM the BAB-430
offers then a better overall performance than the BAB-410 graphic
module.

Hardware Manual 5
1.3.4 DAC for
Contrast
Control
The BAB-430 offers a 8-bit DAC that is intended for contrast control of
dualscan displays. By writing $00 to $FF into the DAC the output voltage
changes linear from 0V to about 3.2V. The DAC is write-only.
1.3.5 Display Adapter Since there is a wide variety of display types with different interfaces
some adaption is necessary between the 65548 and the display. For this
purpose ELTEC currently offers three types of display adapter. First there
is the BAB-431 which is intended for Sharp 800 x 600 dualscan or TFT
displays. Second there is the BAB-433 which is suitable for nearly all
displays with TTL interface (3.3V or 5V). Third there is the BAB-434
for 5V displays that need CMOS level input. With the BAB-433/434 only
an appropriate cable is necessary for most displays.
