Here How I read and write.
1) Use CSI's USB to serial cable.
2) Use CSI CPS_V3.03.20.
3) just pushed the power button only to turn on the radio
Do not pushed and held P1 with power button (It is only for firmware update only)

USB to MIC connector cable is not for read and write to the radio.
Please use the USB to Serial cable.

Question::
Having trouble reading my new CS800. Downloaded CPS version 3.03.25 and installed under Windows 8.1.


Plugged in the USB to MIC connector cable that came with the radio. Windows downloaded the Prolific driver.

Plugged the cable into the mic jack, pushed and held P1 with power button. Red-green LED flashes like its supposed to.

Go to CPS and hit READ RADIO and get error message PLEASE CHECK WHETHER THE USB IS OCCUPIED OR NOT CONNECTED.
