Some open-style connectors provide a temporary connection for a PC or other
configurable tool using probe holes. For connection, insert the prongs of a
probe cable into the probe holes of a connector. Mechanical keys on the
connector prevent improper insertion.
About open-style taps
Open-style taps provide a way for drop cables to be connected to the trunk
line using open-style wiring connections. Three sets of 5-position color-coded
wiring chambers accommodate all wires (for entering trunk cable, exiting trunk
cable, and drop cable). The open-style tap can be mounted on a DIN rail.
Jack screws on open-style taps and connectors provide additional physical
support.
