Simply combine the EOM-104 Embedded Module with the Evaluation Kit to start porting the relevant software, and create a solution for the applications you wish to implement.

Combining the EOM-104-DK with the Embedded Module

Insert the EOM-104 Embedded Module vertically onto the EOM-104-DK. Note that the Pin marked "JP1" on the Embedded Module must be matched with the Pin marked "JP5" on the EOM-104-DK. Be careful when installing the board to avoid damaging the pins.

TURBO RING	Green	Lights up when the Turbo Ring function is enabled
RING MASTER	Green	Lights up when device is set to Ring Master.
GPIO 1 to 4	Green	Lights up when GPIO output is 1.
Port 1 to 4	Green	Ethernet port status is “Link”
Port 1 to 4	Flash	Ethernet port is transferring data.

Wiring Requirements

This section describes how to connect the EOM-104 Evaluation Kit to devices.

Please read the following 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.
• 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 to all devices in the system.
• Be sure to disconnect the power cord before installing and/or wiring your EOM-104 Evaluation Kit.

ATTENTION

Safety First!

Be sure to disconnect the power cord before installing and/or wiring your EOM-104 Evaluation Kit.

Temperature Caution!

Heat sink might be needed for temperature-sensitive environments if the U2 component on the EOM-104 is hotter then 135^ C.

Connecting the Power

You may use the power jack for connecting the power. The power input range of the EOM-104 Evaluation Kit is from 12 to 24 VDC. If the power is properly supplied, the "Power" LED will light up in yellow after 3 to 5 seconds.

External Power Input

The EOM-104 Evaluation Kit also accepts 3.3 V power input through J5 connector. There is no protection on JP5 to EOM-104. Make sure this external power input is within 3.3 VDC±5% and is capable of providing 1 A of current or higher.

Grounding the EOM-104 Evaluation Kit

Grounding and wire routing help limit the effects of noise caused by electromagnetic interference (EMI).

Connect the ground wire from the ground screw to the grounding surface before connecting devices.

ATTENTION

This product should be mounted to a well-grounded mounting surface such as a metal panel.

FG: The Functional Ground contact is the PTH(Plated Through Hole) screw hole at left of J4 as shown in left figure. Be sure to connect the FG wire to an appropriate grounded metal surface.

Console Ports and Pin Assignments

The serial console port on the EOM-104 Evaluation Kit is a DB9 type RS-232 DTE port, which supports TxD, RxD, DTR, DSR and GND signals. It is designed to configure the EOM-104 embedded module. It can be connected to a PC through a null modem cable.

The pinouts of the RS-232 console port are shown in the figure below.

Schematic

This chapter describes how to design your product with the EOM-104 embedded module to complying with EMI and EDS standards.

The printed circuit board is the most important factor that affects EMI, ESD and the performance. The design skills in this chapter are to minimize digital and common mode noises and provide shielding between the PCB's internal circuit and the external environment. These PCB design skills should apply to the entire PCB design.

The following topics are covered in this chapter:

General Rules
Power Ground Rules
□ Chassis Ground
□ Magnetic Noise Zone
☐ Differential Signal Layout
□ ESD Protection

General Rules

Place components so as to avoid long loop traces. Choose a metal box to shield the printed circuit board.

Use a ferrite core on the DC power cord to reduce EMI. PCB and Layout Guideline Provide controlled impedance on all high-speed digital signals traces with right termination schemes to prevent reflection and ringing. Ensure that the power line is rated for the application and optimized with decoupling capacitors. Keep power and ground noise under 100mV peak to peak. Ensure that the switching DC-DC converter is filtered and properly shielded as the DC-DC power converter can produce a great deal of EMI noise. Avoid via and pad in the path on any critical signal as via and pad will induce unwanted capacitance and inductance which can cause reflection and distortion.

Power Ground Rules

Do not split the ground plane into separate planes for analog, digital, power pins. A single and contiguous ground plane is recommended. Route high-speed signals above a solid and unbroken ground plane. Fill copper in the unused area of signal planes and connect these coppers to the ground plane through vias. Stagger the placement of vias to avoid creating long gap in the plane due to via voids.

Chassis Ground

The chassis ground and magnetics serve two purposes: they help to reduce EMI noise emissions from the signal ground plane to the PCB's external environment and also act as a shield to protect the PCB components from ESD. Place the chassis ground on all PCB layers and use connection mounting holes to join the chassis ground on different PCB layers This chassis ground on the PCB is directly connected to the metal shield of equipment through the connection mounting holes. Use a trench/moat to isolate the chassis ground plane from the signal ground plane. The chassis ground region extends from the front edge of the PCB board (RJ45 connectors) to the magnetics and around the edge of the board as shown in below.

Magnetic Noise Zone

Void both power and ground planes on all PCB layers directly under the magnetics. Chassis ground should extend from the magnetics to the RJ45 connector. Do not route any digital signals between the PHY and RJ45 connector. Add transformer to Port 1 and Port 2 as shown in figure 3 when connecting to external cable is required.

Differential Signal Layout

Differential pair (TX+/- or RX+/-) should be routed away from all other signals and keeps 100 ohms differential Impedance. Keep both traces of each differential pair as identical to each other as possible.

Route each differential pair on the same PCB layer. Route both TX+/- and RX+/- pairs far away from each other at least 20 mil space as shown below.

ESD Protection

Various ESD protection methods and devices can be used. The level of ESD protection provided by each method varies and depends on the type of protection device used. Consult the specific manufacture's data sheet to determine the level of ESD protection and proper connection. The most essential in ESD protection is to discharge ESD energy to earth and avoid the ESD voltages destroy or cause the circuitry malfunctioning.

Place transient voltage suppressor (TVS) devices and Ferrite bead on the TX +/- and RX+/- differential pairs as figure 4 to help increase ESD protection. These devices are connected in parallel with the I/O lines to be protected.

Connect all unused inputs to either ground with a 1K resistor or power with a 10K resistor, depending on the desired strap-in setting of the chip.
