TC read channel data

 1'''
 2Temperature_TC - TC_read_channel_data.py with asynchronous mode.
 3
 4This example demonstrates how to read thermocouple from USBDAQF1TD.
 5
 6First, it shows how to open thermal port and configure thermal parameters.
 7Second, read channel 1 thermocouple data.
 8Last, close thermal port.
