This article describes how to test RS485 communication between ROV Control Unit and PC computer with RS485 to RS232 converter. Test programs are provided to test transmission from 2400bps to 115200bps.

There are 2 programs. The first one is prepared for Windows, the second for Atmega16 chip. Windows program sends random data to ROV Control Unit. Atmega16 sends back all data to desktop computer. If sent and received data is the same communication works properly.

To run BASCOM program under JTAG, output file must be loaded into AVR Studio.

First you must download AVR Studio 4 from Atmel website. Then BASCOM must generate output file that is accepted by AVR Studio.
