The following figure identifies the 9-pin D-type male connector pins as seen when looking into the
connector. The tables list the pin assignment for a typical connector in modes asynchronous with controls
and transparent without controls. These tables also list the color of the wire connected to the
corresponding pin in the cables offered by ECI for connecting the tributary connector and a distribution
frame.
