Wall Mounting

The MC-7400 can be installed on a wall by using the wall-mounting kit that is included in the package.

STEP 1: Use eight screws for each bracket and attach the brackets to the rear of the MC-7400.

STEP 2: Use two screws (Ø3.7 mm, 60 mm in length) per side to attach the MC-7400 to a wall.

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.

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your

Wiring Caution!

Calculate the maximum possible current in each power wire and common wire. Observe a

the wiring could overheat, causing serious damage to your equipment.

Temperature Caution!

Be careful when handling

internal components generate heat, and

consequently the outer casing may feel hot to the touch.

NOTE

The DC model should be supplied by

representative

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.

• 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.

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.

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.

on a well-grounded surface, such as a metal panel.

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.

list.

Select 16 kilobytes (Default) for Cluster size.

Enter a drive name under New volume label.

Select the Quick format, Create a bootable disk

using FreeDOS, and Create extended label and

icon files format options.

Click Start to format and create the bootable USB

drive.

Step 2: Prepare the Upgrade File

refers to version numbers).

2. Copy the file to the Bootable USB Disk.
