Other Parts Discussed in Thread: ISO1430, ISO1450
Hi,
I'm going to work on ISO3088 to design Half-duplex RS485 circuit which is already developed but not tested. I want to implement Modbus protocol on the top of RS485.
When I compared my circuit with that of reference design which I found under Technical Support section of ISO3088, I saw that there is no pullup register being used in our design on input line A.
Please find the attached circuit. I also attached reference design. The image with black background is my design.
I have limited knowledge of hardware therefore I have very basic question -
Will this circuit work? Will I be able to use Modbus protocol on it?
Thanks,
