When fabricating the cable, refer to the connection diagram in this section. Though this connection
diagram is not the connection diagram of the QC30R2, it is identical in functions.
The following must be observed in fabrication:
1) Always use a shielded, multi-core cable and connect the shield with SD securely.
2) The optional communication cable is 3m(10ft) long. When the cable is fabricated, its maximum
length is 15m(49ft) in offices of good environment with minimal noise.
