5 Test Setup

The test setup consists of the LAUNCHXL-F280049C development board and custom PCB boards. Figure 5-1 and Figure 5-2 show the actual circuit diagrams for boards under test. Figure 5-3 shows the test setup. Small adapter boards plugged directly to the C2000? MCU LaunchPad? convert UART interface to CAN or RS-485. Small converters in the middle translate the signal to SMAART wire bus interface compatible. Printed circuit boards on the right host individual TMP107-Q1 temperature sensors.
