CAN INTERFACE

Mini Module CAN AVR is provided with a powerful hardware CAN inbterface, capable to reach the maximum bit rate of 1 Mbp/sec.Signals CAN L and CAN H are available respectively on pins

8 and 9 of CN1.

This interface is fully compatible with CAN 2.0 specifications parts A and B.

DIP SWITCH

CAN AVR Mini Module is provided with two dip switches (ab eight ways and a four ways) whose purpose is to set up several electric parameters of module itself and the card operating mode.

In fact DSW1 allows to decide whether serial interface USART0 must be buffered as RS 232 or TTL, in this latter case allowing to use and external buffer like RS 422, RS 485 or current loop drivers.

Four ways DSW2 allows to decide whether the signals of CAN interface or the signals of SPI interface must be available on pins 8 and 9 of CN1.

DSW1 also allows to connect or not the back up battery of RTC + SRAM module.

In addition, status of some swithces can be acquired by software through reading specific microcontroller signals (PA2 and PA3).
