To use these diagrams, wire pins with the same names to each other. For example, the Transmit Signal on the radio connector is wired to the Transmit Signal on the TNC connector. Manufacturers have been known to change their usage of pins, you should compare these diagrams with the product's manual. Damage may occur if wrong connections are made.
Many manufacturers use alternate names for their pin descriptions.
Some of these names appear in Chapter 5 as well as descriptions of the pin functions, which may provide insight to interpreting the descriptions given in radio and TNC manuals. When the radio documentation's pin-out diagrams are unclear or not included, reading the mic schematic may be your best resource.
