This is the default configuration. All the MegaRAC M300V card UART0 signals are routed to the
motherboard’s serial port connector and the motherboard’s serial port TXD and RXD signals are
routed to OPMA SoL pins that are routed to the MegaRAC M300V card UART 1.
In this configuration the X4 De-MUX direction is from Y to A and the X5 MUX direction is from
B to Y. In this configuration the MegaRAC M300V card can re-direct the
SoL input serial data
to
a remote location through the MegaRAC M300V card’s dedicated LAN. Additionally the
SoL
input serial data
can be viewed via the MegaRAC M300V card UART0 through the
motherboard’s serial connector simultaneously.
