MOXA UC-3400A Series Arm Based Computers Installation Guide
Overview
Moxa’s UC-3400A Series computers can be used as edge gateways in the field for data pre-processing and transmission, as well as for other embedded data-acquisition applications. The series includes a diverse set of models, each supporting different wireless options and protocols.
The UC-3400A’s advanced heat-dissipation design makes it suitable for use in temperatures ranging from -40 to 70°C. In fact, the Wi-Fi and LTE connections can be used simultaneously in both cold and hot environments, allowing you to maximize data pre-processing and transmission capabilities of your applications in harsh operating environments. The UC-3400A comes equipped with Moxa Industrial Linux, a high-performance industrial-grade Linux distribution with long- term support that is developed by Moxa.

Installing the UC-3400A
The UC-3400A can be mounted on to a DIN rail or on to a wall. The DIN-rail mounting kit is attached by default. To order a wall-mounting kit, contact a Moxa sales representative.
DIN-rail Mounting
To mount the UC-3400A on to a DIN rail, do the following:
- Pull down the 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 on to the DIN rail as shown in the illustrations below.
- Once the computer is mounted properly, you will hear a click and the slider will rebound back into place automatically.
Wall Mounting (optional)
The UC-3400A can also be wall mounted. The wall-mounting kit needs to be purchased separately. Refer to the product datasheet for information on the wall-mounting kit to be purchased. For the mounting dimensions, refer to the figure below:
To mount the computer on to a wall, do the following:
- Attach two wall-mounting brackets with four M3 x 5 mm screws on the right side panel of the computer as indicated in the figure.
- Use another four screws to fasten the computer on to a wall or a cabinet.
The additional four screws are not included in the wall-mounting kit and must be purchased separately. Refer to the following specifications for the additional screws to be purchased.
Head Type: Pan/Doom
Head Diameter:
5.2 mm < Outer Diameter (OD) < 7.0 mm
Length: > 6 mm
Thread Size: M3 x 0.5P - Push the computer to the left to ensure the computer is securely fixed to the mounting surface.
Connector Descriptions
Power Connector
Connect the power jack to the terminal block located on the top panel, and then connect the power adapter to the power jack. Use a 12 to 24 AWG wire and secure the plug by screws with a minimum torque value of 0.5 N-m (4.4253 lb-in).
After the power is connected, it takes about 10 to 30 seconds for the system to boot up. Once the system is ready, the READY LED will light up.
ATTENTION
The wiring for the input terminal block must be done by a skilled person. The wire type should be copper (Cu).
ATTENTION
The product is intended to be supplied by a UL Listed Power Unit marked “L.P.S.” (or “Limited Power Source”) and rated 9 to 48 VDC, 1.2 A (min.), Tma = 70°C. If you need further assistance with purchasing the power source, contact Moxa for further information.
If you are using a Class I adapter, the power cord must be connected to a socket-outlet with an earthing connection.
Grounding the Computer
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI).
The grounding screw or GS (M4-type screw) is located on the top panel. When you connect to the GS wire, the noise is routed directly from the metal chassis to the ground point.
NOTE The grounding wire must have a minimum diameter of 3.31 mm² .
Ethernet Port
The 10/100/1000 Mbps Ethernet port uses the RJ45 connector. The pin assignment of the port is shown below:
Serial Port
The serial port uses the DB9 male connector. It can be configured by software for the RS-232, RS-422, or RS-485 mode. The pin assignment of the port is shown below:
CAN Port
The UC-3424A and UC-3434A models come with two CAN ports which use the terminal block connector and are compatible with the CAN 2.0A/B standard.
SIM Card Slot
The UC-3400A comes with a Nano-SIM card slot, a console port, and a microSD slot on the front panel.
To install SIM cards, do the following:
- Remove the screw on the slot cover.
The UC-3400A comes with a Nano SIM card slot.
- Push the SIM card tray in and then pull it out to remove it.
ATTENTION
When the tray slot is open, ensure that LAN2 is not connected to the network. - The SIM card tray can install two SIM cards one on each side of the tray.
- Install the SIM card in SIM1 slot. Install the other SIM card in SIM2 on the other side of the tray.
- Insert the tray into the SIM card slot and secure the cover to the slots.
To remove the SIM cards, push the tray in before releasing it.
Console Port
The console port located on the left side of the SIM card slot is a RS- 232 port that can connect to a 4-pin pin header cable. You can use this port for debugging or firmware upgrade.
microSD Slot
There is a microSD slot located above the SIM card slot. Insert the microSD card into the slot. To remove the card, push it in first and release it.
USB Port
The USB port is a type-A USB 2.0 port, which can be used to connect to a type-A USB storage device.
NOTE
It is recommended that the peripheral devices installed should be placed at least 25 mm away from the UC-3400.
Connecting Antennas
The UC-3400A comes with various antenna connectors to the following interfaces.
Cellular
The UC-3400A models come with a built-in cellular module. Connect the antenna to the SMA connector with the cellular mark to enable the use of the cellular function.
GPS
The UC-3400A models come with a built-in GPS module. Connect the antenna to the SMA connector with the GPS mark to enable the use of the GPS function.
Wi-Fi
The UC-3430A-T-LTE-WiFi and UC-3434A-T- LTE-WiFi models come with a built-in Wi-Fi module. Connect the antenna to the RP-SMA connector marked W2 to enable the use of the Wi-Fi function.
Bluetooth
The UC-3430A-T-LTE-WiFi and UC-3434A-T- LTE-WiFi models come with a built-in Bluetooth module. Connect the antenna to the RP-SMA W1 connector to enable the use of the Bluetooth function.
Real-time Clock
The real-time clock is powered by a lithium battery. We strongly recommend that you do not replace the lithium battery on your own. If you need to replace 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.
- Dispose of used batteries according to the manufacturer’s instructions.
Accessing the UC-3400A Using a PC
You can use a PC to access the UC-3400A 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-3400A’s serial console port.
