My latest wiring challenge is to establish communication between my laptop and my Samsung Drive using the Smartjog software. I have wired a 3 wire serial cable as per the Drive Manual. Just RX=>TX and TX=>RX and pin5<=>pin5. I am using a Targus USB to serial adaptor on my laptop which installed as COM7. 9600 baud no parity 1stop as per the drive manual. The TX and RX LEDs on the adaptor flash breifly before the error message to check the cable and the power appears. I have tried many various configurations, with no joy. Question? Is there something odd about these drive's serial interface? Do these USB to serial adaptors work?
