E.4 COM3, COM4 SERIAL PORT CONNECTOR

Connector J5 is a 14-way pin header adjacent to J4. It carries the COM3 and COM4

serial port signals. The signals are arranged so that a ribbon cable from J5 can easily

crimp onto a 9-pin IDC D-type connector for COM3.

Pin 1 of the J5 connector can be identified by looking at the J5 silk-screen box that

surrounds the J5 connector on the TP400. A “2” is located close to the pin 1 end of J5

and a “13” is placed close to the pin 14 end. All odd numbered pins are in one row

and all even numbered pins are in the other row.

E.5 AUDIO, A/D CONVERTOR AND CRT CONNECTOR

Connector J6 is a 16-pin right angle pin header. It carries the audio or analog to

digital converter signals and the signals for a VGA CRT display. Also included on the

connector is the Geode GX1 suspend/resume signal.

Note that either the audio signals or the A/D converter signals are brought to the

connector. Thus some pins are given one function in the columns marked "(AUDIO)"

and other functions in the columns marked "(A/D)". Appendix B describes how the

options are selected.

The VGA CRT display signals are usually connected to a 15-pin high density D-type

connector. Pin assignments for this connector are also given in the table.

Pin 1 of the J6 connector can be identified by looking at the J6 silk-screen box that

surrounds the J6 connector on the TP400. A "1" and “2” are located close to pins 1

and 2. All odd numbered pins are in one row and all even numbered pins are in the

other row.
