8.1.1.3 Powering the Sensor
The A200 provides power to the sensor when it is connected to a PC’s USB
port. An internal DC/DC converter boosts the 5 Vdc supply from the USB
connection to a 12 Vdc output is required to power the sensor.
8.1.1.4 Determining which COM Port the A200 has been Assigned
When the A200 driver is loaded, the A200 is assigned a COM port number.
This COM port number is needed when using DevConfig or a PC terminal
software such as HyperTerminal.
Often, the assigned COM port will be the next port number that is free.
However, if other devices have been installed in the past (some of which may
no longer be plugged in), the A200 may be assigned a higher COM port
number.
To check which COM port has been assigned to the A200, watch for the
appearance of a new COM port in the list of COM ports offered in the software
