If this type of interface is to be used, positions 1, 3, and 5 of
S501 must be set to OFF to prevent damage to the RS-232
transceivers.
12.4 Engine Application Port - 40-Pin Connector (X600)
The system connector header is used when the application
requires direct access to any particular pin available in the
system interface of the module (i.e., digital audio pins). This
applies to the Gx-47/48 modules.
Note!
Special care shall be taken when using the header connector in
order to prevent damage to the RS-232 transceivers. The
following table shows how to set the switch S501 when using
the Application Port.
