Functional summary
CANbus ports
Each CANbus network controller is implemented with the industry standard
SJA1000 device providing compliance with CANbus 2.0B specification. Each
channel includes a fully isolated CANbus transceiver powered from an external
supply (specified as +5v).
The CAN4000-8S provides a ‘weak’stub termination network for each channel.
The user must provide an external split termination network at each end of the
CANbus network as shown below.

RS-422/485 serial ports
The CAN4000-8 provides eight channels of serial communications using either RS-
422 (full duplex) or RS-485 (half-duplex). Each channel offers separate Tx / Rx
differential pairs and includes jumper selectable 150Ωtermination resistors (see
TERM jumpers).
The serial channels support baud rates to 10Mbps.
For full duplex RS-422 mode, the CAN4000-8S provides the transmit and receive
pairs along with ground. The maximum cable length for RS-422 systems is 1200m
(4000ft) and supports a single transmitter and up to 10 receivers.
When used in half-duplex RS-485 mode, the user must provide an external
connection between the Rx and Tx pairs (care must be taken to match the Rx+ to
Tx + and Rx- to Tx-). An RS-485 network has the same cable limits as RS-422 but
supports up to 32 transmitter and 32 receiver devices.

Host interface
The CAN4000-8 has a full 32-bit PC/104 -Plus (PCI Rev 2.2) 3.3v host interface
(with 5v tolerance) to the host computer. On board jumpers allow the CAN4000-
8S to be configured for any of the 4 logical PC/104 -Plus stack levels of the host
computer.

Ordering information
The following part number(s) can be used when ordering:
CAN4000-8S 4 CAN ports, 8 serial ports (0 to +60°C)
CAN4000-8S-EXT 4 CAN ports, 8 serial ports (-40 to +85°C)
Anti-static handling
The board(s) supplied contain electrostatic components that are susceptible to
permanent damage from electrostatic discharge (static electricity). To prevent
electrostatic discharge, the boards are supplied in anti-static packaging.
When handling a board, observe the following anti-static precautions to alleviate
risk of damage:
▪Remove the board(s) from the packaging only when you are working on an
anti-static, earthed surface and wearing an anti-static wrist strap.
▪Retain the anti-static packaging that the board(s) were supplied in. If you
remove a board from a system, store it in this packaging.
RoHS compliance
The European RoHS Directive (Restriction on the use of certain Hazardous
Substances –Directive 2002/95/EC) limits the amount of six specific substances
within the composition of the product. The CAN4000 is RoHS compliant.
