Cabling
Several cabling schemes are possible for both AILC and RILC modes. 
Typical capacitance for 24- and 26-gauge cables is shown in the Tables 163 
and 164. RS-232 and RS-422 transmission distance is limited by the electrical 
capacitance of the cable. Low-capacitance cable carries a digital signal 
further than a high-capacitance cable.
 shows the cabling choices available. It includes 
cabling with the RS-232-C cable, associated patch panel, the RJ-11, and the 
octopus cable. Each scheme can be tailored to suit individual needs, and 
specific alternatives are shown in later figures.
