MC-7400 Series HW UM Hardware Connection Description
Wiring Requirements
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 together with power wiring in the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately. • • • 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. It is advisable to label the wiring on all devices in the system.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your MC-7400.
Wiring 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
The MC-7400 Series comes with a 100 to 240 VAC power input for AC power model, or a 24 VDC power input (via the terminal block) for DC power model. If power is supplied properly, the Power LED will light up. For safety reasons, please use DC terminal block cables with the following specifications:
Wire range: 14-22 AWG NOTE
The DC model should be supplied by a UL-listed power source, whose output meets the ES1 standard and is rated at 24 VDC, 4.06 A (min.). If you need further assistance selecting a power source, contact a Moxa representative.

MC-7400 Series HW UM Hardware Connection Description
Grounding the MC-7400
Grounding and careful wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting the power.
ATTENTION
This product is intended to be mounted on a well-grounded surface, such as a metal panel. The location of the earthing/grounding wire on the terminal block power connector is shown in the diagram below. Connect the wire to an appropriately grounded metal surface.
Connecting Data Transmission Cables
This section describes how to connect the MC-7400 computer to the network and/or serial devices.
Connecting to the Network
Plug your network cable into the computer’s Ethernet port. The other end of the cable should be plugged into your Ethernet networking device. When the cable is properly connected, the LEDs on the embedded computer’s Ethernet port will glow to indicate a valid connection. The 10/100/1000 Mbps Ethernet LAN ports use 8-pin RJ45 connectors. The following diagram shows the pinouts for these ports. The LED indicators on the right-top (for the upper LAN connector) and right-bottom (for the lower LAN connector) corners glow a solid green color when the cable is properly connected to a 100 Mbps Ethernet network. The LED will flash on and off when Ethernet packets are being transmitted or received. The LED indicators on the left-top and left-bottom corners glow a solid yellow color when the cable is properly connected to a 1000 Mbps Ethernet network. The LED will flash on and off when Ethernet packets are being transmitted or received.

Upgrading the BIOS
This section describes how to upgrade the BIOS. IMPORTANT BIOS upgrades, if not done correctly, can permanently damage the computer. We strongly recommend that you contact Moxa’s technical support staff for assistance in order to obtain all necessary tools and the most current advice before attempting to upgrade the BIOS on any Moxa device.
Step 1: Create a Bootable USB Disk
Before upgrading the BIOS, you must create a bootable USB RAM drive, which you can use as a system rescue device. A useful software suite, Rufus for creating a bootable USB RAM drives can be downloaded at: https://rufus.akeo.ie/ To create a bootable USB disk using Rufus software, do the following: 1.
Start Rufus and select the USB device that you want to use as a bootable disk from the Device drop-down list. 2.
Select MBR partition scheme for BIOS or UEFI computers to boot from a legacy BIOS or UEFI. 3.
Select FAT (Default) from File system drop-down list. 4.
Select 16 kilobytes (Default) for Cluster size. 5.
Enter a drive name under New volume label. 6.
Select the Quick format, Create a bootable disk using FreeDOS, and Create extended label and icon files format options. 7.
Click Start to format and create the bootable USB drive.
ATTENTION
We suggest you use a USB drive with under 2 GB disk space, as larger USB drives may not support FAT file format and consequently fail to boot.
Step 2: Prepare the Upgrade File
You must use the BIOS upgrade installation file to upgrade the BIOS. Contact Moxa’s technical department for assistance. 1.
2.
Get the BIOS upgrade installation file. The file name should have following format: 682AxxSx.exe (xx refers to version numbers). Copy the file to the Bootable USB Disk.
4-15
MC-7400 Series HW UM
Step 3: Run the upgrade program on the MC-7400 Computer
1.
2.
Reboot the computer, press F12 while booting up to enter the Boot Manager Select USB Disk as the first boot source. Press Enter to continue.
BIOS Setup
3.
When the boot up process is complete, the DOS screen is displayed. Go to the directory where the upgrade file is located. For example, if the upgrade file is stored in the DA-720 folder, type
cd DA-720.
C:\cd DA-720 4.
Run the upgrade program by typing DA-72010017.exe. Please note that the upgrade filename will vary depending on the computer versions. C:\ DA-720>DA-72010017.exe 5.
Wait until the upgrade process is complete.
4-16
MC-7400 Series HW UM BIOS Setup
6.
When the upgrade is finished, the computer will automatically reboot. You can check the BIOS version on Main page of the BIOS Setup to confirm the upgrade.
ATTENTION
DO NOT switch off the power supply during the BIOS upgrade, since doing so may cause the system to crash.
