5. Connection to a Network 
The following is an explanation of the connection method of the E71 to the 10
Point
(1)Installation procedures of the network require sufficient safety measures. For the execution of such operations as terminal processing of connection cable, trunk line cable etc., please consult with a trained professional.
(2)When the customer's products match the EMC instructions and the low voltage instructions for connecting E71, use the method in (4) below to install the ferrite core.
(3)When there is a communication error caused by high frequency noise due to the installation environment, take the following steps.
•The ferrite core can be installed using the steps in (4) below.
•When communicating with TCP/IP, increase the count of communication retries.
•When connecting to 10
•When connecting to 10BASE2, use a double shielded coaxial cable.
Shield
•When connecting to 10BASE5 or 10BASE2, ground the shield of the coaxial cable at both the local station and companion connected device. (Ground at a place near the connector.)
(4)Below are the steps for installing the ferrite core based on connection to the 10BASE5 network.
Please install the ferrite core ( 
1) on the side of the E71 or external devices / the AUI cables transceiver.
1 It is possible to use a TDK Corporation style ZCAT
(For 10BASE5 connection)
