Board must be 2.5 mm
Connect all the shield lines of the communication cables and then ground the
shield at one end of the network. The wiring method is shown below.

Note The terminals of the same type are connected internally. Connections can thus
be made to either the right or left half of the end Boards.
When connecting a communications cable to a Controller Link Support Board,
connect the cable to the attached connector first and then attach to the connec-
tor on the Board. Connect the communications cable to the connector using the
following procedure.
1. Peel back the cover of the cable for about 50 mm without scratching the
mesh of the shield. Do not peel too much because it may cause a short-cir-
cuit.
2. Twist the mesh of the shield to form a line on the end on which the shield is to
connected to a node.
3. Apply a heat-shrink tubing to the twisted shield line, leaving enough bare
wire to attach the crimp terminal.
