EM-1220-DK Development Board

The EM-1220 Development Kit is a well-designed PCB board with complete layout. The kit helps users evaluate,

develop, and integrate the EM-1220 Embedded Module into their systems and applications. Simply combine the

EM-1220 Embedded Module with the Development Kit to start porting the relevant software, and create a

solution for the applications you wish to implement.

Refer to the following picture for the basic layout of the EM-1220-DK.

Combining the EM-1220-DK with the Embedded

Module

Insert the EM-1220 Embedded Module vertically onto the EM-1220-DK. Note that the Pin marked “J1” on the

Embedded Module must be matched with the Pin marked “J1” on the EM-1220-DK; and the Pin marked “J2” on

the Embedded Module must be matched with the Pin marked “J2” on the EM-1220-DK. Be careful when

installing the board to avoid damaging the pins.

LED Indicators

The following table explains the function of the LED indicators located on the EM-1220-DK.

LED Name LED Color LED Function

Ready Green Power is on and system functions normally.

P1, P2 (Tx) Green Serial port 1, 2 is transmitting data.

Off Serial port 1, 2 is not transmitting data.

P1, P2 (Rx) Yellow Serial port 1, 2 is receiving data.

Off Serial port 1, 2 is not receiving data.

Wiring Requirements

This section describes how to connect the EM-1220 Development Kit to serial devices.

You should heed the following 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.

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.
