Installing the UC-8100A-ME-T
DIN-rail Mounting
The aluminum DIN-rail attachment plate is already attached to the product’s
casing. To mount the UC-8100A-MET on to a DIN rail, make sure that the stiff
metal spring is facing upwards and follow these steps.
- Pull down the bottom slider of the DIN-rail bracket located at the back of the unit
- Insert the top of the DIN rail into the slot just below the upper hook of the DIN-rail bracket.
- Latch the unit firmly onto the DIN rail as shown in the illustrations below.
- Push the slider back into place.
Wall Mounting (Optional)
The UC-8100A-MET can be mounted with a wall-mounting kit that needs to be
purchased separately. Follow these steps to mount the computer on to a wall:
Step 1
Use four screws to fasten the thewall-mounting brackets on the left panel of
the computer.
Step 2
Use another four screws to mount the computer on a wall or a cabinet
Connector Description
Power Connector
Connect the power jack (in the package) to the UC-8100A-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-8100A-MET
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.
| Pin | Signal |
|---|---|
| 1 | Tx+ |
| 2 | Tx- |
| 3 | Rx+ |
| 6 | Rx- |
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 mode. The assignments for
the ports are shown in the following table:
| Pin | RS-232 | RS-422 | RS-485 |
|---|---|---|---|
| 1 | TXD | TXD+ | – |
| 2 | RXD | TXD- | – |
| 3 | RTS | RXD+ | D+ |
| 4 | CTS | RXD- | D- |
| 5 | GND | GND | GND |
SD/SIM card Sockets
The UC-8100A-ME-T comes with an SD socket for storage expansion, and a SIM
card socket for cellular communication. The SD card and SIM card sockets are
located at the lower part on the front panel. To install the cards, remove the
screw and the protection cover to access the socket, 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 a 4-pin pin header
cable. You can use this port for debugging or firmware upgrades.
| Pin | Signal |
|---|---|
| 1 | TxD |
| 2 | RxD |
| 3 | NC |
| 4 | GND |
USB Port
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.
Antenna Connectors
There are three antenna connectors on the front panel of the UC-8100A-ME-T. W1 and W3 are for cellular modules, and W2 is for the GPS module. All three connectors are of SMA type.
Real-time Clock
The real-time clock in the UC-8100A-MET 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 incorrect type of battery.
Accessing the UC-8100A-ME-T Using a PC
You can use a PC to access the UC-8100A-MET by one of the following methods:
A. Through the serial console port with the following settings:
Baudrate=115200 bps, Parity=None, Data bits =8, Stop bits =1,
Flow Control =None
ATTENTION
**** Remember to choose the “VT100” terminal type. Use the console cable to
connect a PC to the UC-8100A-ME-T’s serial console port
B. Using SSH over the network. Refer to the following IP addresses and login
information:
| Default IP Address| Netmask
---|---|---
LAN 1| 192.168.3.127| 255.255.255.0
