CANbus
Network Interface Module for PC/104 Bus Computers
INTRODUCTION
The CAN104 is a Controller Area Network (CAN) adapter for PC/104 bus
computers. CAN is the data link layer technology used by DeviceNet and
Smart Distributed System. The CAN104 supports 8-bit transfers and takes
advantage of the additional interrupts on the expanded bus.
The CAN104 incorporates the Philips SJA1000 CAN stand-alone controller
chip which is used widely in both the automotive and general industrial
environments. Besides being backward compatible with the older 82C200,
the SJA1000 has more features than its predecessor. The 82C200 is
restricted to BasicCAN (11-bit identifiers) while the SJA1000 operates in
either BasicCAN or a new mode called PeliCAN™ which supports the CAN
2.0B specification (29-bit identifiers). The SJA1000 maintains extended
frame passivity while in the BasicCAN mode.
The SJA1000 features a 16 MHz clock, a larger receive buffer and better
acceptance-filtering — including the ability to extend the acceptance mask
to the data field. It has the ability to operate at data rates as great as 1 Mbps.
The CAN104 incorporates the DeviceNet physical layer with an optically
isolated transceiver providing reverse voltage and short-circuit protection.
Field connectors include the DeviceNet 5-position open style and DB-9 as
defined by CAN in Automation (CiA).
The PeliCAN mode includes:
Error counters with read/write access
Programmable error warning limit
Last error code register
Error interrupt for each CANbus error
Arbitration lost interrupt with detailed bit position
Single-shot transmission (no re-transmission)
Listen only mode (no acknowledge, no active error flags)
Hot plugging support (software driven bit rate detection)
Acceptance filter extension (4-byte code, 4-byte mask)
Reception of 'own' messages (self reception request)

  • Page 3: Installation

    The CAN104 should be mounted closer to the motherboard than any 8-bit modules that may be in the stack. If the CAN104 is the last module in the stack, secure it with panhead screws (not provided) to complete the mounting.
  • Page 4: Configuring Jumper Settings

    CAN ground by installing a jumper on JP7. Termination If the CAN104 is located at the end of a trunk, line-matching impedance is required. A 121-ohm resistor is supplied for this purpose. If a different impedance is needed, jumper JP8 should be removed and the alternative impedance connected to screw terminals CAN_H and CAN_L.
