    Switches 3.2.5 SW5: Emulation and Control Switch SW5 provides the means to break several signals so that they can be con- trolled by an emulator plugged into J14. This switch also provides a means of setting the operating mode of the MSC1211. Table 3−3.

  • Page 22: I/O Connectors And Signals

    The host PC communicates with the MSC1211EVM through this connector, which is a D-shell type, 9-pin female, pinned out in the usual manner. Some of the flow control lines are used for special purposes by the MSC1211EVM board; these are described in Table 3−4.

    I/O Connectors and Signals 3.3.2 J9: Serial1 RS-232 Connector This connector is available for use with the second UART in the MSC1211. Only the TD and RD lines are used. The DTR pin is connected to the DSR pin, and the RTS pin is connected to the CTS pin. In the RS-232 electrical specification, −5V to –15V on a line indicates a log- ic high (mark), and +5V to +15V indicates logic low (space).
