After the factory default configuration has been loaded, the system will reboot automatically. The Power LED will blink on and off for the first 5 seconds and then maintain a steady glow once the system has rebooted. We recommend that you only use this function if the software is not working properly, and you want to load factory default settings. The Reset to Default functionality is not designed to hard reboot the UC-8100-MET. ATTENTION Reset to Default will erase all the data stored on the boot storage Please back up your files before resetting the system to the factory default configuration. All the data stored in the UC-8100-ME-T`s boot storage will be erased when it is reset to the factory default configuration. Real-Time Clock The UC-8100-ME-T's real-time clock is powered by a lithium battery. We strongly recommend that you do not replace the lithium battery without help from a qualified Moxa support engineer. If you need to change the battery, contact the Moxa RMA service team. WARNING There is a risk of explosion if the battery is replaced with an incorrect battery type. UC-8100-ME-T Series Hardware User Manual 9 Placement Options There are two sliders on the back of the unit for DIN rail and wall mounting. DIN-Rail Mounting 1.

UC-8100-ME-T Series Hardware User Manual 11 3. Hardware Connection Description This section describes how to connect the UC-8100-ME-T to a network and connect various devices to the UC-8100-ME-T. Wiring Requirements In this section, we describe how to connect various devices to the embedded computer. You must pay attention to the following common safety precautions, before proceeding with the installation of any electronic device: · 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 the wires for signal or communication 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 which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together. · Keep input wiring and output wiring separate. · We strongly advise that you label wiring to all devices in the system for easy identification. ATTENTION Safety First! Be sure to disconnect the power cord before installing and/or wiring the computer. Electrical Current Caution! Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment. Temperature Caution! Be careful when handling the unit. When the unit is plugged in, the internal components generate heat, and consequently the outer casing may be hot to touch by hand. UC-8100-ME-T Series Hardware User Manual 12 Connecting the Power Terminal Block The UC-8100-ME-T has a 3-pin terminal block for a 12 to 36 VDC power input. The figure shows how the power input interface connects to external power sources. If the power is properly supplied, the Power LED will light up. The Power LED will glow a solid green color when the operating system is ready (it may take 30 to 60 seconds for the operating system to boot up). ATTENTION This product is intended to be supplied by a Listed Power Supply Unit that is rated to deliver 12 to 36 VDC at a minimum of 500 mA @ 12 VDCC. Grounding the Unit Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices to the computer. ATTENTION This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel. SG: The Shielded Ground (sometimes called Protected Ground) contact is the bottom contact of the 3-pin power terminal block connector when viewed from the angle shown here. Connect the SG wire to an appropriate grounded metal surface. ATTENTION A shielded power cord is required to meet FCC emission limits and also to prevent interference with nearby radio and television reception. It is essential that only the supplied power cord be used. You are cautioned that changes or modifications not expressly approved by the party responsible for compliance could void your authority to operate the equipment. UC-8100-ME-T Series Hardware User Manual 13 Connecting to the Console Port The UC-8100-ME-T is provided with a 4-pin pin-header RS-232 console port, which is a located on the top panel. This port is designed for connecting serial console terminals, which you can use to view the boot up messages, and to troubleshoot when the system does not boot up. Serial Console Port & Pinouts Serial Console Cable Pin Signal 1 TxD 2 Rada 3 NC 4 GND Connecting to the Network Connect one end of the Ethernet cable to one of the UC-8100-ME-T's 10/100M Ethernet ports (8-pin RJ45) and the other end of the cable to the Ethernet network. If the cable is properly connected, the UC-8100-MET will indicate a valid connection to the Ethernet in the following ways: The LED indicator in the lower right corner glows a solid green color when the cable is properly connected to a 100 Mbps Ethernet network. The LED will flash on and off when Ethernet packets are being transmitted or received. The LED indicator in the upper right corner glows a solid orange color when the cable is properly connected to a 10 Mbps Ethernet network. The LED will flash on and off when Ethernet packets are being transmitted or received.
