6.4  Connecting to a PC which is not Connected to a Network 

 

If the PC is equipped with an Ethernet card but not connected to a network, a local 
network address should be used for communication between the Converter and the PC. 
The PC-E converter is shipped with a default IP address 192.168.0.112. For direct 
connection between the PC and the Protocol converter, a crossover Ethernet cable is 
required. 
 

 

 

 

 
 
 

To setup your PC to connect directly to the Protocol converter PC-E, an IP address in the 
same range as the Protocol converter must be assigned to the PC. In Windows 
environments, this should be done as follows: 
 

•

 

Connect the PC and the Protocol converter together using a crossover cable 

•

 

Open the Windows Control Panel 

•

 

Select Network 

•

 

Select TCP/IP -> the PC's Ethernet adaptor from the Configuration tab as shown 
below
