Hi Richard
There are 2 versions, can you tell me what is reported in the web interface ?
(Or post screenshot)
If it is pl2303, then in the web interface configure the correct port/baud
The baud is most probably 9600, the ports ar numbered like this ...
P1 | P3
ETH-------------------------
P2 | P4
If it is not pl2303, it shoul configure automatically
Thx
Lee
