2.1.3.3 Connectivity to Universal Asynchronous Interfaces (P1 + X5)

Figure 23:

RS-232 Interface Connectors (P1, X5) and Jumpers

The phyCORE-OMAP44xx Carrier Board provides connectivity to three of the four universal asynchronous
interfaces of the phyCORE-OMAP44xx. The signals of UART2 and UART3 are available on the Dual-Port Connector
P1 at RS-232 level, whereas the signals of UART1 are brought out on the expansion connector X5 at TTL level.

shows the signal mapping of the two female DB-9 connectors at connector P1.
