Planning and Designing RIO Cable System
890 USE 101 00 October 2006 23
z Each drop on the two trunks must have a unique RIO network address
Part Numbers Part numbers for basic components and tools that may be used in linear topology
coaxial cable networks are listed here to familiarize readers. Specific trunk and drop
cable selection is determined using information contained in this guide. Semirigid
cable components are not listed.
Note: RIO statistics using the STAT block will not provide the true status of each
drop because the drops will only be attached to one of the two RIO ports at the
head processor. Also, an error LED will be ON at the RIO processor.
Note:
z The maximum length of the trunk cable is determined by the specified
attenuation of the cable type and the number of other cable hardware
components along the network
z The minimum length permitted for a drop cable is 8.5 ft. (2.6 m)—a shorter drop
cable can create tap reflections that can cause errors in the drop adapter
z the maximum coaxial drop cable length is 164 ft. (50 m)—it can be expanded
with a fiber optic link
z A minimum spacing of 8.5 ft. (2.6 m) must be maintained between taps. Each
unused port in a tap needs to be terminated with a Modicon 52-0402-000 Tap
Port Terminator.
