Choosing the right Product:
Product B&B Supplied Items Customer Requirements Advantages Disadvantages Pricing Model
Box 
Interface external box

Optional OBDII Y-Cable

On-board computer (OBC) with
RS-232 Serial Port
 Software to read/write to serial
port

Quickest time to market

No hardware modification required to
the OBC
 Automatic updates to new units

Most expensive solution

Two cables in the installation
 Can’t test OBC/OBDII combination
until install

Per-piece hardware price
Daughter
Board  OBDII module with plug-
in interconnect &
mounting holes

Optional OBDII Y-Cable
 OBC with TTL serial port,
matching plug-in interconnect, 5V
Supply, DB-15 connector to go to
OBDII Y-Cable.
 Software to read/write to serial
port
 Minimal software integration.
 Reduce steps of installation
 Less expensive than box
 Automatic updates to new units
 Test OBC/OBDII combination in the
factory at build time
 PCBD Change required on OBC
 OBC enclosure has to accommodate
daughter board
 Possibly more expensive than chip
set.
 Per-piece hardware price
Chip Set  Schematic
 Bill of Materials

Example layout

FPGA HW Description
 Firmware in executable
form
 Integrate Streamer design into
the OBC.
 Software to read/write to serial
port
 Source OBDII chip set for
production
 Minimal software integration.
 Reduce steps of installation

Can lay out OBC PCBD to fit best in
enclosure
 Possibly less expensive than daughter
board
 Test OBC/OBDII combination in the
factory at build time
 Extensive PCBD layout on OBC
 Software updates for OBDII have to
be implemented in customer
production
 Any hardware updates require a new
PCBD layout for the OBC.
 Requires high quantities of chip set
purchase to get cost savings.
 Replicates processors compared to IP
version.
 First year NRE
 Consecutive year
maintenance fee
 Per-piece license fee
IP Libraries  Firmware in library form
(CAN Only)
 Embedded Database
(CAN Only)
 Design a CAN interface into the
OBC
 Write an interface between the
Streamer libraries and the OBC
application.
 Write board support libraries
between the Streamer libraries
and the OS/Hardware.
 No redundant hardware costs.
 Can achieve a small form factor.
 No support for vehicles without CAN
(older than 2008)
 Extensive software integration
required.
 Hardware CAN interface design
required.
 Longest time to market
 Software updates for OBDII have to
be integrated into software before
production
 First year NRE
 Consecutive year
maintenance fee
 Per-piece license fee
