Reboot

To reboot the computer, press the programmable button for 1 second.

Reset to Default

Press and hold the Programmable function (FN) button between 7 to 9 seconds to reset the computer to the factory default settings. When the reset button is held down, the User programmable (USR) LED will blink once every second and become steady after 7 to 9 seconds. Release the button within this period to load the factory default settings.

Real-time Clock

The UC-8200’s real time clock is powered by a non-chargeable 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 type.

Installation Options

DIN-rail Mounting

The aluminum DIN-rail attachment plate is already attached to the product’s casing. To mount the UC-8200 on to a DIN rail, make sure that the stiff metal spring is facing upwards and follow these steps

Wall Mounting (optional)

The UC-8200 Series can be mounted on to a wall using a wall-mounting kit as shown in the following illustrations. The optional wall-mounting kit is not included in the product package and should be purchased separately. Follow these steps to mount the computer on to a wall:

IMPORTANT!

The diameter of the screw heads should be greater than 7 mm and less than 14 mm; the diameter of the shafts should be less than 3 mm. The length of the screws should be greater than 6 mm.

NOTE

• Test the screw head and shank size by inserting the screws into one of the keyhole shaped apertures of the wall-mounting plates before attaching the plate to the wall.
• Do not drive the screws in all the way—leave a space of about 2 mm to allow room for sliding the wall mount panel between the wall and the screws

3. Hardware Connection Description

In this chapter, we describe how to connect the UC-8200 to a network and various devices.
The following topics are covered in this chapter:

• Wiring Requirements
• Connecting the Power
• Grounding the Unit
• Connecting to the Network
• Connecting to a USB Device
• Connecting to Serial Ports
• Inserting the microSD Card
• Connecting to the Console Port
• Connecting the CAN Port
• Connecting the Digital Inputs and Digital Outputs
•  Inserting the SIM Card
• Installing the Cellular Module
•  Installing the Wi-Fi Module
• Connecting the Antennas

Wiring Requirements

In this section, we describe how to connect various devices to the embedded computer. Be sure to read and follow these 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 signal or communication 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 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.
• When necessary, it is strongly advised that you label wiring to all devices in the system.

ATTENTION

Safety First!

Be sure to disconnect the power cord before doing installations and/or wiring.
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 feel hot to the touch.

Connecting the Power

Connect the power jack (in the package) to the UC-8200 Series’ 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. Both models support dual power inputs for redundancy.

WARNING

• This product is intended to be supplied by a UL Listed Power Adapter or DC power source marked ‘L.P.S.” (or “Limited Power Source”) rated 12-48 VDC, 0.25 A (minimum), and Tma= 85°C (minimum).
• The power adapter should be connected to a socket outlet with earthing connection. If you need further information or assistance, contact a Moxa representative.

Grounding the Unit

There is a grounding connector on the top panel of the computer. Use this connector to connect a well-grounded mounting surface, such as a metal panel. Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI).

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.

Connecting to the Network

The two Ethernet ports are located on the front panel of the UC-8200 computers. The pin assignments for the Ethernet port are shown in the following figure. If you are using your own cable, make sure that the pin assignments on the Ethernet cable connector match the pin assignments on the Ethernet port.

Connecting to a USB Device

The UC-8200 Series computers come with a USB port located at the lower part of the front panel, allowing users to connect to a device with an USB interface. The USB port uses a type A connector. By default, the USB storage is mounted at /mnt/usbstorage.

Connecting to 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:
