6.3. UART Signals (P2, P3, J1, J6)
Two RS232 transceiver circuits and DB-9 connectors (P2, P3) are provided on the evaluation board to connect the
CP2105 virtual serial ports to external serial devices. See Table 3 for the RS232 P2 and P3 pin descriptions. The
J2 and J6 connectors are provided to facilitate direct access to the CP2105’s UART signals. Shorting blocks on J1
are required to connect the Standard UART signals to P2, and the shorting blocks on J6 are required to connect
the Enhanced UART signals to P3. See Table 4 for J1 and J6 pin descriptions.
