5.11 Modular Mode

When used in modular mode as shown in Figure 5-7, the power is supplied through a single USB connector; the same USB connector J5 is also used for data transfer through the CP2015 USB to UART converter. When enumerated correctly, the 2 UART ports are displayed on the device manager as a Virtual COM Port, similar to that shown in Figure 5-6.

The SICP2105 drivers must be installed to access the UART port. Download and install the drivers here.

The enhanced COM port is the application/user UART and the standard COM port is the data port.

The S1 switch setting for functional and flashing mode is shown in Table 5-5.
