ControlNet Standard and High-flex Coax Cable 3 Determining Trunk-cable Section Lengths A ControlNet segment is comprised of one or more sections of trunk cable separated by taps and terminated at both ends. The total cable length of a segment is equal to the sum of all the trunk-cable sections.
PAGE 4
ControlNet Standard and High-flex Coax Cable The following tables and examples are provided to help you determine the lengths of cable you can use in your system. if you are using The total allowable length of a segment depends on the standard RG-6 cable (1786-RG6/A with attenuation of 5.99 dB) number of taps in your segment (there is no minimum trunk-cable section length requirement). The maximum allowable total length of a segment is 1,000 m (3,280 ft) with two taps connected.

ControlNet Standard and High-flex Coax Cable 5 You can increase the total trunk-cable length or number of taps by installing repeaters on the segment. This creates another segment. The following examples explain how you can calculate allowable lengths of segments for standard RG-6 (1786-RG6/A), and high flex RG-6 (1786-RG6F/A) cable, as well as for a system that combines the two types of cables.

ControlNet Standard and High-flex Coax Cable EXAMPLE Example 3: Determining the maximum allowable length of standard cable when mixing standard RG-6 and high-flex RG-6F cable in the same system In this example, the segment: • has 7 nodes (requires 7 taps) • requires 656.2 ft (200 m) high-flex 1786-RG6F cable 1. Calculate the amount of standard 1786-RG6 cable that is equivalent to 656.2 ft (200 m) of 1786-RG6F cable by multiplying the ratio between the two attenuations by the length of RG-6F cable. (13.
