How can I tell if a single-ended terminator is active or passive?
• Answer: If the terminator is not marked, try the following: With a multimeter that will measure low resistance values, measure from a TERMPOWER pin to a GND pin. If it reads greater than 50 ohms and you get different values with the probes interchanged, it is an active terminator. If the resistance value is less than 50 ohms it is a passive terminator.
