Support Information
3.3.1
Connector J78 connects to the UART1 pins of the i.MX27 MCU. UART1 is the primary functionality of
the pins. This female DB9 connector is configured for RS-232 DCE operation. Figure 3-3 shows pin
assignments and Table 3-3 provides signal descriptions for the connector.
3.3.2
Connector J79 connects to the UART3 pins of the i.MX27 MCU. UART3 is the secondary functionality
of these pins. This male DB9 connector is configured for RS-232 DTE operation. Figure 3-4 shows pin
assignments and Table 3-4 provides signal descriptions for the connector.
