Chapter 3 Support Information

3.1Introduction

This section contains connector pin assignments, connector signal descriptions, and other useful information about the M9328MX21ADSE. Both the CPU and Base board connectors are described.

The tables in this section list signal names as they appear in the schematics for the boards. The figures usually refer to the same signal name, but may substitute a generally accepted standard name for that function. For example, all RS-232 transmitted data signals are referred to as TXD regardless of which RS-232 connector is being illustrated. Also, the use of “_B” at the end of a signal name indicates that the active state of the signal is logic level zero or ground potential (active low).

3.2CPU to Base Board Connectors PX1, PX2, PY1, and PY2

The PX1 and PX2 connectors located at the bottom side of the ADS CPU card connect this board to the ADS Base board through connectors PY1 and PY2 located on the top side of the board. Figure 3-1shows the pin assignments for the PX1 and PY1 connectors. Table 3-1provides signal descriptions for these connectors. Figure 3-2shows the pin assignments for the PX2 and PY2 connectors and Table 3-2provides signal descriptions for these connectors.
