Signal Descriptions and Pinout Tables

The following section describes the signals found on the four X connectors located on
the bottom of the module. X1, X3, and X4 connectors are ETX
while the X2 connector complies with the XTX
This table describes the terminology used in this section for the Signal Description
tables. The PU/PD column indicates if an XTX
been used. If the field entry area in this column for the signal is empty, then no pull-up
or pull-down resistor has been implemented. The "#" symbol at the end of the signal
name indicates that the active or asserted state occurs when the signal is at a low
voltage level. When "#" is not present, the signal is asserted when at a high voltage
level.
