Overview

Established in 1994, the company's business is in the fast
growing market of Multiplex Communication. YAMAR is developing
products based on its patented DC-BUS technology for
communication on noisy battery power lines for applications in
the fields of Automotive Electronics, Security, Cellular, Mobile
Computing, to name but a few.

The DC-BUS technology enables communication of Data, Voice, Music
and Video signals by digital means over Direct Current (DC)
battery lines like those used in every vehicle. YAMAR succeeded
to deploy advanced digital communication techniques tailored to
overcome hostile and noisy environment such as on vehicle battery
lines in a small size silicon device. Customers integrate the
devices into modules utilizing their own application (e.g. within
Navigation modules for communication with cars' Odometer).

YAMAR has solutions for each of the multiplexed data
communication bus categories:
** Mechantronics - The QDC family of devices for multiplex
communication @ 10Kbps for command and control of applications
such as Sensors and Actuators commonly used in vehicles (e.g.
Climate control, Door module, Immobilizer, Obstacle detector).
Interface to Synchronous, J1850 and CAN Protocols.
** Telematics - DCB device is designed for Voice and Data
communication bus @ 250Kbps. This solution will proliferate with
the deployment of the emerging data bus standard (SAE ITS Data
Bus).
** Multimedia - DCB102 for Music communication - Yamar introduced
a prototype for CD quality music @1.7Mbps on a DC power line.
Application example: link between CD Changer in the trunk and a
Head unit on the dashboard.

DC-BUS Benefits
* Flexible Car Electronics Architecture
* Saving the Cost and Weight of Ordinary Wiring
* Flexible Modifications of new installations
* Simplicity of installation, only single connection to a
battery line required
* Additional data bandwidth on the battery line of existing data
buses
* No modification is needed for protocols such as J1850, CAN,
IDB.

The company sees the mass markets as its strategic focus.
Therefore, its main activity is in Europe, Japan and USA, where
multi million vehicle manufacturers and their tear one suppliers
expressed the interest in the DC-BUS technology. The company is a
member of the ISO TC22 WG1 for vehicle serial communication and
in the Society of Automotive Engineers (SAE) ITS Data Bus (IDB)
committee. YAMAR's potential market is greater than $150M a year.
