I have a sysmac omron plc C200H CPU01,only the power led is ON,using CX programmer software, and connecting to the plc via Host link LK202-V1 with RS422 Port, I'm using an USB to RS232 and an RS232 to RS422 converter, the wiring setup is according to the Omron manual.When I try direct on line, the RCV Host Link led starts blinking and then after few moments, I get fail error to connect.Do you have any recommendations?Thanks
