  • The maximum segment length of 10 BASE-T is 100m (Length between a module and a hub). Generally, the straight cable that sending (TD) and receiving (RD) are twisted inside is used. In case you connect two communication modules one to one, use in the cross cable type.

  • When you connect a hub to an optional card (Ethernet card), use one to one (Straight cable) connecting cable. The connection is like the following table. But, as the jack is for 8 pins, the remaining lines are connected as they are.

  •  Twist Line RD(+) – Line TD(+) and Line RD(-) – Line TD(-) to make one to one Cross cable.

  • As 10 BASE-T cable is structurally weak against external noise, twist the lines for Pin 1 and Pin 2, which are TD+ and TD-, and the lines for Pin 3 and Pin 6, which are RD+ and RD-, each other. After that, assemble the two twisted lines to make the wiring resistant against noise.

  • The power for a hub is to be separated from the power for a PLC. Use the power resistant against noise as the power for a hub.

  • The cable is to be installed 100 ㎜ away from the line on which high current flows such as power line.

  • Please consult with an expert to process and manufacture cable terminal.
