The output of the sensor is an analog one with voltage 0-5V. I expected to get GPS data and also those sensors data. Based on the information that the T2-301 has two Serial Port, can I connecting the GPS trough Serial Port 1, and converting the sensors to RS-232 output, then connect them to Serial Port 2 ?
