WALLED LAKE, MICHIGAN, JUNE, 2002 — eXtend Computer & Instrument, a
company that specializes in electronics for mobile applications, introduces
macCAN. macCAN is a software and hardware package which allows Macintosh
users to interface with standard Controller Area Networks (CAN) commonly
used in automotive and industrial applications. macCAN works with all
PowerPC Macintosh computers using either a serial or USB port running OS 8
through OS X.

macCAN supports both standard 11 bit and extended 29 bit CAN message IDs
with data rates up to 1 Mbps. All CAN timing parameters are user
programmable including propagation time, synchronization jump width and bit
phase times. The macCAN interface has 120 ohm user selectable termination
and CAN connections to the interface are easily made through standard
instrumentation banana jacks or via a standard 3-pin header (both provided).

macCAN software uses a 100uS resolution clock to sequence all transmitted
messages and log received messages. Transmitted messages may be programmed
with 0 to 8 data bytes and all data bytes are easily programmed by the
user. Every transmit message can be manually sent at any time, scheduled to
be sent at a specific time or sent at a fixed periodic rate. macCAN
monitors all messages present on the CAN bus. Messages specified by ID are
displayed in the macCAN Message Activity Window when received. Messages may
also be selectively logged at the time of reception or transmission and
saved in either a comma separated value (CSV) or tab delineated text file

The macCAN software is available with either a USB or serial CAN interface
for Macintosh. The USB interface powers itself directly from the USB port.
The serial interface requires external power provided by an included AC
adapter (12 volt auto adapter cord is optional).

US and International orders may be placed today exclusively through eXtend
Computer & Instrument. The macCAN software and hardware package is priced
at $349 and will begin shipping in August of 2002. To purchase macCAN,
