About direct connection
Connect devices directly to the trunk line only if you can later remove the
devices without disturbing communications on the cable system.
About open-style connectors
Open-style connectors come in two primary varieties:
• five-position (5 pin linear plug)
• ten-position (10 pin linear plug)
Ten-position connectors provide easier daisy-chaining because there is an
independent wire chamber for each wire (entering cable and exiting cable).
IMPORTANT
If a device provides only fixed-terminal blocks for its
connection, you must connect it to the cable system by a
drop line. Doing this allows you to remove the device at the
tap without disturbing communications on the cable
system.
