CANLY V2.0

The CANLY modules operate as I/O expanders for a Controller Area Network (CAN) system, supporting CAN V2.0B active, with bus rates up to 1 Mbit/s.

I/O functions include

individually selectable transmit-on-pinchange messages for each input, message scheduling capability, 10-bit PWM output, device configuration via CAN bus messages

One mask and two acceptance filters are provided to give maximum flexibility during system design with respect to identifiers that the device will respond to.

The device is pre-programmed in non-volatile memory so that the module defaults to a specific configuration at power-up

Through an RS-232 port, the module can be configured and I/O operations can be performed locally. In addition, the serial interface can output received and transmitted CAN messages.
