    3. AES termination: AES signals should have one and only one termination. This termination should physically be at the last destination of an AES coax cable. If the eVAM1-1 is the last connection in a series of AES connections, then its terminations should be turned on. A symptom of too many terminations (or no termination) is that no signal appears to be present on the AES input.
