General Purpose Serial Ports
The conga-STX7 provides two general purpose serial ports (SER0 and SER1) on the feature connector X32. The SER1 signals are routed to one
of the following connectors:
•
feature connector X32 (default)
•
pin header X25, via the BMC (assembly option)
Use switch SW3 to route the module’s SER1 port to the feature connector or to pin header X25.
Note
For X32 pinout description, see section 4.13 “Feature Connector”.
