**MOXA UC-1200A Series Fanless Industrial Computer Installation Guide

**

Overview

The UC-1200A computing platform is designed for embedded data acquisition applications. The UC-1200A is built around an Armv8 Cortex-A53 dual-core 1-GHz processor and comes with two RS232/422/485 serial ports, two 10/100/1000 Mbps Ethernet ports, and a Mini PCIe socket to support cellular modules. These versatile communication capabilities let users efficiently adapt the UC-1200A to a variety of complex communications solutions.

Installing the UC-1200A

DIN-rail Mounting

The DIN-rail mounting plate comes attached to the product’s casing. To mount the UC-1200A on to a DIN rail, pull out the bottom slider, latch the unit onto the DIN rail, and push the slider back in.

Wall Mounting (optional)

The UC-1200A can be mounted using a wall-mounting kit, which needs to be purchased separately. Follow these steps to mount the computer on to a wall:

Step 1: Use four screws (M3 x 4 mm) to fasten the wall-mounting brackets on the left panel of the computer.

Step 2: Use another four screws (M3 x 6 mm) to mount the computer on a wall or a cabinet.

Connector Descriptions

Power Connector

Connect the power jack (in the package) to the UC-1200A’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.

ATTENTION

The wiring for the input terminal block should be installed by a skilled person. The wire type should be copper (Cu), wire size should be 14 to 16 AWG, and a torque of 0.19 n-m should be used for V+, V-, and GND connections. The wire size of the power input and earthing conductor should be the same. The recommended wire stripping length is 6 to 7 mm.

WARNING

The product is intended to be supplied by a UL Listed Power Unit marked “L.P.S.” (or “Limited Power Source”) and is rated 12 to 24 VDC, 0.6 A min., Tma = 60°C (min). If you need further help with purchasing the power source, please contact Moxa for further information.

WARNING

The means of power cord of adapter should be connected to a socket-outlet with earthing connection.

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-1200A

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 right-most 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 10/100/1000 Mbps Ethernet ports (LAN 1 and LAN 2) come with RJ45 connectors. The pin diagram of the ports is given below:

10/100 Mbps

1000 Mbps

Serial Ports

The two serial ports (P1 and P2) come with terminal-block connectors. Each port can be configured by software for the RS-232, RS-422, or RS-485 mode. The pin assignments for the ports are given below:

USB Port

The USB 2.0 port is located at the lower part of the front panel. By default, the USB auto-mount is disabled. If enabled, the USB storage is mounted at /media/USB_P1/media/USB_P2.

Micro SD/SIM Card Sockets

The UC-1200A comes with a Micro SD socket for storage expansion and a SIM card socket for cellular communication. The Micro SD card and SIM card sockets are located on the lower part of the front panel. However, the screw is located at the left panel of the device. To install the cards, remove the screw and protection cover to access the sockets and insert the Micro SD card or the SIM card into the sockets. Ensure that the cards are inserted in the correct direction. Refer to the instructions above the socket. 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 upgrade. The console port is located on the top panel of the device and is accessible after removing the cover of the slot.

Antenna Connectors

The UC-1200A provides a Mini PCIe socket for installing a wireless module. You can purchase the A-CRF-SMIF-100 antenna accessory with an SMA connector. Two SMA-type wireless antenna connectors W1 and W2 are located on the front panel.

Real-time Clock

The real-time clock in the UC-1200A 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. Replace only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s instructions.

Placing the Round Stickers on the Screws

Three round stickers are included in the product package. Stick one of them on to an external screw as indicated in the figure below to help detect unauthorized access and tampering.

To place the sticker, do the following:

1. Use a cloth to clean the surface of the screw with a 75% alcohol solution.
2. Use a tweezer to place the sticker on the screw.
3. Press the sticker down on to the screw for at least 15 seconds with a pressure of about 15 psi (pound/square inch)
4. Keep the device at room temperature for 24 hours before deploying it.

NOTE

1. Place the sticker carefully on the screw because it is thin and fragile.
2. The ideal environment to store the stickers is at 22°C (72°F) and less than 50% relative humidity.
3. Keep the extra two stickers in a safe place so that only authorized persons can access them.
