Mitsubishi E71N-U-HW Connection to a Network, For 10BASE5 connection E71, AUI cable, Ferrite core

5. Connection to a Network

The following is an explanation of the connection method of the E71 to the 10 BASE-T, 10BASE5 or the 10BASE2.

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 BASE-T, use an unshield twisted pair cable (UTP category 5).

•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 2032-0930.

Transceiver

(5)When using A1SJ71E71N-B5T, when the FG signal is regulated on the side of the external power supply of the original power supply for the transceiver, ground the FG signal at the original power supply.
