Can you change to serial port 3? Did the drivers for silicon labs get installed (there are 2)
The thread subject mentions 6555, so if correct then no serial ports involved.
'Downloaded the software on my new computer': Do you mean installed from the WL CD? Just downloading the WL 6.0.3 update won't get you very far.
Then if you do indeed have a 6555 WeatherlinkIP logger, obviously you need the TCP/IP option in Communications Port. Check the instructions supplied for the details.
I used the WL link cd that came with the product.
The bar code on the box has 6555.
Did the set up process again. Got to the baud reading on the set up at 19200 on the vantage pro 2 consul.
Went back into the set up process.
This time used the communication port TCP/IP connection.
Do I need to click one of the box sections in the TCP/IP connection such as local device ID, remote IP address or web download?
If I run the test an error pops up - TCP/IP:communications error found. check local settings & try again.
Did not have this issue when I first set up the system over a year ago.
