ISO1044: CAN Bus to RS485 Converter

Hello Varun, 

Thank you for reaching out. It would be fairly simple to switch from a CAN transceiver to a RS485 transceiver. RS485 supports full and half duplex configurations (CAN is half-duplex) and the microcontroller protocol would have to change.  

Do you have a block diagram of what you are looking to accomplish?

Best,

What is "FO"?

Do you require isolation?

Both CAN and RS-485 are half-duplex buses; you should be able to simply replace all the transceivers.

RS-232 uses unidirectional signals, so one master would require separate lines to communicate with multiple slaves.

Hi Andrew 

The S/W is part of a Board made by another group.

Without changing the S/W which requires this group to come in;

whether one can change that to MODBUS where I can use 

a Fibre Optic ( FO ) transmission for Rx / Tx ?

Hi Clemens 

Thanks for your prompt reply.

Yes, we do require Isolation for which we thought of using FO .

For MODBUS it's relatively simple, using one Fibre Optic Transmitter 

and Receiver at both ends.

Problem is the S/W of CANBUS which requires an ACK signal .

Without changing the S/W was wondering if any easy way out was there 

like this Module from Mornsun TD3USPCAN?
