2.5.2 MX20 I/O Data Port Configuration
The I/O product variation of the MX20 supports an array of additional I/O capabilities on connector J2
as shown below. Note that the hardware connected to the MX20 I/O ports must be connected as shown
in Table 2-2, as reconfiguration by software is not available. See the sample wiring diagrams and
connector pin outs in section 2.5.7 for detailed connections. One possible configuration is shown in
Figure 2-11.
