The following table lists the specifications of the coaxial cables used for the coaxial bus
system.
The high frequency coaxial cable "3C-2V" or "5C-2V" (conforms to JIS 3501) is used.
However, when configuring a multiplexed remote I/O network for redundant system,
use a double shield coaxial cable. (Refer to section 4.8.2.)
