Q: is the ground pin of each channel connected together or each channel is totally isolated?

Hi, the ground of the control terminals is connected together, and each channel at the input is completely isolated.

Q: Why do the commands not work when input into a serial terminal connected to the com port assigned? using putty 9600bps 8n1 i have added \r\n

Not sure what you entered there and if you have a proper serial port through the USB interface. Note there are many bytes to fransfer including a checksum if I remember correctly. (Did create some Python code which uses python usb)

Q: Is it possible to expand this module to control more than 16 channels? If no, any other alternatives plz?

You can use a RPI with for example 4 modules, but It's better using 8-Channel USB because it contains serial number, so you have the possibility to identifiy witch module you use. It isn't possible with 2 module 16 channels on a RPI.
