when i connect two PCs at the serial ends, the PCs are able to communicate.
But when i replace one PC with an RTU, im unable to communicate with the RTU.
To troubleshoot the problem, i disconnected the RTU and looped the TX and RX of the serial.
i noted the wiz110SR reclaculates the checksum before transmitting to RTU.
Is it possible to prevent the wiz110SR from recalculating the checksum? since the RTU rejects the newly calculated checksum?
I need the wiz110SR to be totally transparent and allow the serial end-to-end communication to flow.
I will appreciate if you can give me any other information needed.
configurations for WIZ110SR :
