STEP 3: Once the screws are fixed in the wall, insert the four screw heads through the large parts of the keyhole-shaped apertures, and then ⇒ slide the NI UES-3880 downwards, as indicated. Tighten the four screws for added stability. Wiring Requirements WARNING Do not disconnect modules or wires unless the power supply has been switched off or the area is known to be non-hazardous. The devices may only be connected to the supply voltage shown on the type plate. The devices are

You should also pay attention to the following items: Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point. NOTE: Do not run signal or communications wiring and power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately. You can use the type of signal transmitted through a wire to determine

where it is not needed. Packets that are used in maintaining the operation of the network (such as the occasional multi-cast packet) are forwarded to all ports. The NI UES-3880 operates in the store-and-forward switching mode, which eliminates bad packets and enables peak performance to be achieved when there is heavy traffic on the network. Switching and Address Learning The NI UES-3880 has an address table that can hold up to 1K node addresses, which makes it suitable for use with lar
