1 Introduction The PCAN-TJA1054 bus converter establishes a connection between a High-speed CAN bus (ISO 11898-2) and a Low-speed CAN bus (ISO 11898-3). One of the most important potential applications of the bus converter is a simple connection between a PEAK CAN interface (e.g., PCAN-USB) and a Low-speed CAN bus.
CAN bus connection via D-Sub, 9-pin (in accordance with CiA® 106) 5-Volt power supply through pin 1 of the High-speed CAN connection. Nearly all CAN interfaces by PEAK-System can provide the required supply Extended operating temperature range from -40 to +85 °C (-40 to +185 °F)
2 Connectors 2.1 Connecting the High-speed CAN Side The PCAN-TJA1054 is designed for a direct connection to a HS-CAN component (e.g. PCAN-USB). The HS-CAN side has a 9-pin D-Sub connector. The pin assignment corresponds to the specification CiA® 106. Pin assignment HS-CAN Attention! Make sure, that the HS-CAN component always is turned off when connecting or disconnecting the PCAN-TJA1054.
A single node should be terminated with at least 500 Ω and at most 6 kΩ. To simplify the adaptation of the PCAN-TJA1054 to an existing CAN bus you can switch between the terminating resistors 560 Ω and 5.66 kΩ using the slide switch.
CAN bus, it is not capable of activating one of the low- power modes. If the PCAN-TJA1054 shall be connected to the LS-CAN bus of a motor vehicle, that uses a low-power mode, the following should be considered: In a low-power mode all transceivers in a motor vehicle terminate CAN_L against the battery.
Appendix D Quick Reference High-speed CAN socket Connect or disconnect the PCAN-TJA1054 only, when the relevant HS-CAN component is turned off! Low-speed CAN plug Slide switch Low-speed CAN termination 560 Ω for building smaller networks, testing single components 5.66 kΩ for monitoring or configuring existing networks (already terminated...
