Thankyou very much for responding
As in the project there are four major parts 1. arduino /2.LCD / 3. USB to RS 45 converter module/ 4. MAX485 TTL to RS-485 /5Servo motor . I'm not using servo motor , LCD interface is OK, Circuit Connections are OK, connections of USBRS485 and MAX TTL to RS is also correct. but i can't say whether they are working or not.

Check the connection first. Are you using exactly same circuit? Did the code compiled properly?
