3.3 Protocol Interface
The product has two CAN protocol chips at a frequency
of 16 MHz. The SJA1000 chip is connected to the 9 pin
D-SUB connector with the CiA pinning. The optional
82527 is also connected to the 9 pin D-Sub connector
without physical line driver.
The C165 uses the CS2 signal to select the SJA1000.
The NetPorty II can be equipped with a second CAN
channel. Therefore a 82527 will be mounted on the
PCB. The C165 uses the CS3 signal to select the
82527.
If 2 CAN channels are used there is no standard pinning
at the D-Sub connector. The physical line driver for the
second CAN channel is available via the connecting
cable (not included in standard delivery contents) and
can be used optional by your special application.
In stade of the second CAN channel a diagnosis
channel can be used. Therefor an UART 16CS550 can
be mounted on the PCB instead of the 82527. The
C165 uses the CS3 signal to select the UART.
The physical line driver for the ISO 9141 interfacing can
be ordered separately
