Installing the UC-8112-ME-T

Two sliders are provided at the back of the unit for DIN-rail mounting or wall mounting.
DIN-Rail Mounting

1. The DIN-rail mounting kit is mounted by default as shown in the figure below:
2. Pull down the bottom slider of the DIN-rail bracket located at the back of the unit
3. Insert the top of the DIN rail into the slot just below the upper hook of the DIN-rail bracket.
4. Latch the unit firmly on to the DIN rail as shown in the illustrations below.
5. Push the slider back into place.

Wall Mounting (optional)

1. Remove the four screws on the side-panel silver cover of the device.
2. Place the wall-mount brackets on the silver cover and fasten the screws as shown below. Use only the screws provided in the wall-mounting kit package.

ATTENTION: The wall-mounting kit is not included in the package and must be purchased separately.

Connector Description

Power Connector
Connect the power jack (in the package) to the UC-8112-ME-T’s DC terminal block (located on the top panel), and then connect the power adapter. It takes about 30 seconds for the system to boot up. Once the system is ready, the Power LED will light up.

WARNING EXPLOSION HAZARD!
Do not disconnect equipment unless the power has been removed or the area is known to be non-hazardous.

Grounding the UC-8112-ME-T
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). SG: The Shielded Ground (sometimes called Protected Ground) contact is the top 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.

Ethernet Ports
The two 10/100 Mbps Ethernet ports (LAN 1 and LAN 2) use RJ45 connectors.

Serial Ports
The two serial ports (P1 and P2) use terminal connectors. Each port can be configured by software for RS-232, RS-422, or RS-485. The pin assignments for the ports are shown in the following table:

SD/SIM Card Sockets

The UC-8112-ME-T comes with an SD socket for storage expansion, and a SIM card socket for cellular communication. The SD card/SIM card sockets are located at the lower part on the front panel. To install thecards, remove the screw and the protection cover to access the sockets, and then insert the SD card or the SIM card into the sockets directly. You will hear a click when the cards are in place. To remove the cards, push the cards in before releasing them.

Console Port
The console port is an RS-232 port that can be connected to with a 4-pin pin header cable. You can use this port for debugging or firmware upgrade. Note that the cable is not included in the package.

USB
The USB 2.0 port is located at the lower part of the front panel and supports a USB storage device driver. By default, the USB storage is mounted at /mnt/usbstorage.
Real-time Clock
The real-time clock in the UC-8112-ME is powered by a lithium battery. We strongly recommend that you do not replace the lithium battery without the help of a Moxa support engineer. If you need to change the battery, contact the Moxa RMA service team.

ATTENTION: There is a risk of explosion if the battery is replaced with an incorrect type of battery.

Cellular Module
The UC-8112-ME-T comes with a built-in PCIe socket for wireless communication. To install a cellular module, do the following:

1. Remove the four screws on the DIN-rail mounting bracket and detach the bracket from the unit.
2. Remove the two screws on the rear panel.
3. Remove the four screws on the silver cover on the right panel and remove the cover.
4. Remove the screw on the metal cover.
5. Remove the three screws on the top panel.
6. Remove the two screws on the bottom panel.
7. Check the contents of the cellular module package. The package should contain the items shown below:
8. Remove the metal cover of the computer and locate the cellular module socket.
9. Remove the screw next to the socket and replace it with the bronze screw (in the package) as shown below:
10. Attach one thermal pad to the cellular module cover and the other thermal pad to the module pad.
11. Attach the cellular module to the module pad.
12. Mount the module cover on the cellular module and use screws on both sides to secure the cover.
13. Insert the module into the socket and secure it using a screw from the package.
14. Connect antenna cables to the cellular module. There are three antenna connectors on the cellular module: W1 and W3 are for cellular antennas and W2 is for GPS antenna.
15. Insert the antenna connectors through the antenna cable holes on the front panel of the cover as shown below:
16. Secure the antenna connectors to the cover using a locking washer and nut as shown below:
17. Arrange the antenna cables and use a cable tie to attach the cables to the bronze screw. You may cut the cable tie if it is too long.
18. Plug the antenna onto the connector.
19. Replace the cover of the computer and fasten the screws to secure the cover.
