Trouble shooting
In this manual, only the device operation and the configuration are described. The
testing results, their meaning and the search for errors in the case of poor results are
not contained in this manual. The measurement results and their interpretation are
introduced in the REA training document.
Network error
Prior to a further search for errors, the cables must be checked as well as the
network sockets on the REA device. If the locking mechanism on the plug is broken,
the contact is poor. If the socket on the device is defective, the contact may be poor.
In this cases, a corresponding repair or replacement of the cable is necessary.
Recommendation: Only network hardware supporting 1Gbit/s should be used.
Unshielded (UTP) network cable types should not be used.
Same addresses
The PC and the REA Verifier device have identical network addresses (IP addresses).
They must be different or there will be an IP address conflict.
Several network cards
If a given PC has several network cards, they must be separated with the help of a
logical setting. This is done with the help of an IP mask and basic selection
Example of a bad configuration
Adapter 1
Address:
192.168.111.11
Mask: 255.255.255.0
Adapter 2
Address:
192.168.111.12
Mask: 255.255.255.0
Both network adapters (network cards, including WLAN) work in the same network.
The REA Verifier on adapter 1 sends the data to the PC and the PC can send back the
data through either adapter 1 or 2. If adapter 2 was chosen, the data no longer
comes to the REA Verifier as it is connected to adapter 1. In this case, as an
example, adapter 1 should be set to 192.168.113.11 and the REA device to
192.168.113.12. The Adaptor 2 setting remains unchanged. With this setting,
adapters 1 and 2 are separated.
