a. Detail connection diagram

Details of SIO link connection are illustrated below. Controller link cables are available as options, but
the customer must provide the communication trunk.

b. Producing a communication trunk

[1] Strip the sheath of a double shielded twisted-pair cable by

approx. 15 to 20 mm.

[2] Twist the shield wires and solder them onto the vinyl

wires of AWG22 or equivalent.

[3] Place a cable protection tube over the cable.
[4] Insert the core wires, without stripping them, into the

cable insertion holes in the connector (SDA, SDB,
GND, FG).

[5] With the cable inserted in the press-fit cable housing, apply

pressure from above to pressure-weld the core wires.

[6] Heat-treat the cable protection tube.

e-CON connector pin numbers

Always insert a terminal resistor (220

Ω, 1/4 W) at the end of the communication trunk

(between pins 1 and 2 of the e-CON connector).
