If the communication is not working the following hints may be helpful to locate and solve the prob-
lem.
4.5.4.1. Basic Checks
Verify the following points:
Ethernet cable is properly connected
Ethernet cable is functional (verify by connecting PC to LAN)
Rules for IP address setup are followed (4.5)
4.5.4.2. Check of PC Network Adapter Setup
Make sure the PC has chosen the alternate TCP/IP Settings. Navigate to the network adapter as
shown in 4.5.2.1. This time double-click the network adapter in use to bring up the status dialog. In
the status dialog the Details... button brings up the required information.
The IPv4 Address and Subnet Mask must show the values of the alternate setup (4.5.2.2).
Under some circumstances it may take some time until the PC changes to the alternate setup. If a 2-
3 minutes time of waiting does not change the status a reboot of the PC may be helpful.
