11.2 Why Can't I Communicate with My Logger?
If your logger does not respond when communication is attempted, check that:
the logger or modem is attached to the selected COM port
all connections are secure between the computer and the logger
there are no other applications using the COM port
only one serial port is hardware configured for each COM designation
there are no conflicting IRQ assignments
If the logger still does not work try:
testing the serial port with another application
the software on another computer
other loggers or interface cables
