2 Test Setup and Results

VCC is supplied with external power; 3.3 V or 5 V is recommended. The GND header pins are the ground connection for the TRS3232RGTEVM. The DB9 connector mates with a personal computer's RS-232 port or a USB to RS-232 adapter. For initial testing, external wires can be added. The ideal usage involves connecting the terminal block data and control lines to a system that has an UART (Universal asynchronous receiver/transmitter) onboard.
