APPENDIX B: TIPS ON CONNECTING THE TELEDYNE API ANALYZER RS-232 INTERFACE

Teledyne API analyzers use the RS-232 communications protocol to allow the instrument to be connected to a variety of computer based equipment. RS-232 has been used for many years and as equipment has become more advanced, connections between various types of hardware have become increasingly difficult. Generally, every manufacturer observes the signal and timing requirements of the protocol very carefully. Problems arise when trying to specify connectors, and wiring diagrams that attach the analyzer to various devices.

The problem centers around two areas. First is the physical incompatibility of connectors. Second is the wiring of the connectors. This Note will attempt to provide some guidelines for connecting the Teledyne API analyzers to a variety of other equipment

			Connectors:
			There is a wide variety of connectors
			and cables that are specified to
			operate with the RS-232 protocol.
			This is because electronics have
			decreased in size over the years and
			connectors have been downsized to
			match the electronics.

2.Gender changers - convert a male connector to a female connector or vice versa. They do so WITHOUT changing the pin-to-pin wiring.

3.Adapters - these change from one type plug (DB-9) to another type plug (DB-25). They do so WITHOUT changing the wiring.
