Serial Port Interface, connector assembly P1

In addition to the serial port accessible via the XC2VP30 FPGA, the ALi M1535D+ provides access over the PCI Bus to two serial ports. The ALi M1535D+ employs 16450/16550 Compatible UARTs with Send/Receive16-byte FIFOs. The two Serial ports are connected to the ALi M1535D+ device via two male DB9 connectors (P1). The DB9 connectors are configured as DTE interfaces and meet the EIA/TIA-574standard.

The DB9 male connectors are labeled Serial Port A and B in the ML310 schematics. The DB9 connectors are part of the P1 connector assembly. Please note that Serial Port B is located adjacent to the PS/2 connector where COM1 in a legacy PC is traditionally located. The two DB9 serial port connectors are labeled on the ML310 board silk-screen near the P1 connector assembly. Please review the ALi M1535D+ Data sheets for more detailed information.
