Hi, I have bought a new Silabs EC2 serial adapter for debugging C8051F320 in my SmartRF04EB - CC1101DK433 development board from Chipcon - Texas Instruments. I connected one end to my laptop USB port and other end to the USB MCU debug interface pins of the development board. I tried with connecting both the ways - the red tag in the left side as wella s the right side but there is no notification LED glowing for the power up of the debugger.
