Does the RJ45 protector plug need to be installed on the ruggedized Modbus plus tap 990NAD23010 in order for it to work?

YES. The RJ45 protector plug should be in place to protect the programming port from harmful elements and to establish a positive connection to the RJ45 port pins. When the programming cable is removed, and the RJ45 protector plug is install, it establishes a positive connection to the movable pins inside the RJ45 connector to complete the circuit.
