Middle Machine Number: 10
Middle Machine IP: 192.168.1.10
Server IP: 192.168.1.250
I have set the IP on my PC to 192.168.1.250 and added 192.168.1.250 and 192.168.1.10 to my BTS.ini file so that they appear in the BTS software when launched. I still have the default IP1 of 127.0.0.1 which also appears in the list. I am using a crossover cable between my PC and the control unit (and have also tried a regular ethernet cable). When I run netscan on my PC it only returns my PC name as the IP 192.168.1.250, I see no sign of the control unit. Therefore when I click on 192.168.1.250 in the list in the BTS software, nothing happens. If I click on 192.168.1.10 it tried to connect and gives the error "DB Connection Failed". I'm hoping you can help me figure out what is not set up properly to get my system running as soon as possible.

Obviously, his operation is correct but still doesn't work, why? If you met the same problem, if there's "DB Connection Failed" warning, it means the database doesn't work. Maybe there's something basic was ignored, please try the following steps. 

Step 1: turn off the windows firewall(if it's running, you can turn it off from the 'control panel'-'administrative tools'-'services'-'windows firewall', turn it off) and try connection again.

If connected successfully, please ignore the following steps. Of course, if you don't want to turn off the firewall, then please add bts exceptions in the firewall setting. Please refer to the following picture.

Step 2: If it doesn't work or the firewall isn't running.

Please find the services of MySQL and Neware bts, make sure they are running.

So make sure Neware and MYSQL services are running, set up the correct IP addresses, turn off the Windows firewall(local network) then you are ready to rock!
