Module UART
The conga-HPC/EVAL-Server provides two RS232 UARTs (UART0 and UART1) via the COM-HPC
®
module. The UART0 is on D-SUB9 connector
X65 while the UART1 is on D-SUB9 connector X66. The transmit and receive signals of both UARTs are also routed to the feature connector
X43 (pins19-22).
Use switch SW8 to enable or disable the UART ports from the COM-HPC
®
module. To set the power rail of the module UART0, use jumper JP2.
For module UART1, use jumper JP16 to set the power rail.
