2.7.1 Switches (SW1_1, SW1_2)

The AWR2188EVM contains two switches, SW1_1 and SW1_2, which are used to configure the primary and secondary radar control paths respectively. For typical operation with the DCA2000EVM, set all switches on SW1_1 and SW1_2 to the OFF position.

SW1_1.1

RS232, PMIC_CLKOUT, and MCU_CLKOUT Mux

Set to the OFF position to enable the MSS_RS232, MSS_UARTB_TX, and BSS_UARTA_TX signal path. Set to the ON position to enable the MSS_UARTB, BSS_UARTA, PMIC_CLKOUT, and MCU_CLKOUT signal path.

AWR2188EVM
SW1_1.2

MSS and BSS UARTs

Set to the OFF position to bring the MSS_UARTA, MSS_UARTB_TX, and BSS_UARTA_TX signals to the primary radar connector (J18). Set to the ON position to bring the MSS_UARTA, MSS_UARTB_TX, and BSS_UARTA_TX signals to the onboard FTDI and XDS110.

SW1_1.3

MSS_RS232 and MSS_UARTA

Set to the OFF position to bring the RS232 signals to the primary radar connector (J18). Set to the ON position to bring the MSS_UARTA signals to MUX U12 input (controlled by SW1_1.2).

SW1_1.4

JTAG

Set to the OFF position to bring JTAG to the primary radar connector (J18). Set to the ON position to bring the JTAG to the onboard XDS110.

SW1_1.5

MSS_McSPIA

Set to the OFF position to bring the MSS_McSPIA interface to the primary radar connector (J18). Set to the ON position to bring the MSS_McSPIA interface to the onboard FTDI.

SW1_1.6

MSS_I2C

Set to the OFF position to bring the MSS_I2C interface to the primary radar connector (J18). Set to the ON position to bring the MSS_I2C interface to the onboard FTDI.
SW1_1.7

SOP

Set to the OFF position to bring the SOP interface to the primary radar connector (J18). Set to the ON position to bring the SOP interface to the onboard FTDI.

SW1_1.8

SPI/I2C Selection

Set to the OFF position for SPI mode. Set to the ON position for I2C mode.
