NPort Express DE-211 Serial Installation Enabling a Termination Resistor For RS-422/485 serial communications, when an electrical signal travels through two different resistance junctions in a transmission line, the impedance mismatch will sometimes cause signal reflection. Signal reflection causes signal distortion, which in turn will contribute to communication errors.
NPort Express DE-211 Serial Installation Enabling a User-Supplied Terminator When using the terminal block, you may install your own external terminator resistor by connecting the ends of the resistor directly to inputs 2 and 3, or by connecting the two ends of the resistor to the wires that emanate from inputs 2 and 3, as shown in the following diagrams.

NPort Express DE-211 Ethernet Installation Connecting to the Ethernet Port Connecting to a Hub or Switch For most applications, you will simply plug one end of your Ethernet cable into NPort Express’s 10BaseT port, and the other end into a Hub or Switch that is connected to your network.
NPort Express DE-211 Power Connection Using the Power Adapter Take the following steps to connect NPort Express’s power adapter. Plug the power adapter’s DC plug into NPort Express’s DC-IN jack. Plug the power adapter into an electrical outlet. Note that there is no on/off switch. The server turns on as soon as the connected power adapter is plugged into a live outlet.
