Preface
This USB-CANmodul Systems Manual describes the board's design
and function. Precise specifications for the on-board microcontrollers
can be found in the enclosed microcontroller Data Sheet/User's Man-
ual.
In this manual, and in the attached schematics, low active signals are
denoted by a "/" in front of the signal name (i.e.: /RD). A "0"
indicates a logic-zero or low-level signal, while a "1" represents a
logic-one or high-level signal.
Declaration of Electro Magnetic Conformity for the
PHYTEC USB-CANmodul
PHYTEC products are designed for installation in electrical
appliances or as dedicated Evaluation Boards (i.e.: for use as a test
and prototype platform for hardware/software development) in
laboratory environments.
Note:
PHYTEC products lacking protective enclosures are subject to dam-
age by Electro Static Discharge (ESD) and, hence, may only be
unpacked, handled or operated in environments in which sufficient
precautionary measures have been taken in respect to ESD dangers. It
is also necessary that only appropriately trained personnel (such as
electricians, technicians and engineers) handle and/or operate these
products. Moreover, PHYTEC products should not be operated
without protection circuitry if connections to the product's pin header
rows are longer than 3 m.
