1. Introduction
1.1 Scope
This document serves as a guide on how to get started using the OptConnect ema™ cellular modem. For
demonstration purposes, OptConnect’s ema:Play Evaluation Kit will be used as the host system
throughout this document. Furthermore, it is assumed that ema:Play’s on-board MCU (U16) firmware is
executing the latest GettingStartedWithemaVx.x demonstration project. The latest version of this project is
available at http://optconnect.com/emaPlay . For instructions on how to update ema:Play’s on-board
MCU (U16) firmware, reference the OptConnect ema™ ema:Play User Guide, section 4.1.3 .
Included in this document are instructions for driver installation on Windows operating systems and AT
commands for basic device configuration and setup.
It is recommended that all OptConnect ema™ users familiarize themselves with the material contained in
this document before continuing on to other application notes.

2. ema:Play Setup
2.1 Overview
This section describes how to properly install ema into ema:Play and overall evaluation kit setup. It is
critical to follow the steps detailed in this section to avoid potential damage to ema and/or ema:Play as a
result of improper installation. ema:Play ships with the Getting Started with ema demonstration project
and its hardware is pre-configured to run this project.
2.2 Unpack ema:Play
Carefully unpack ema:Play from its box. The contents of the kit should include the following as shown in
Figure 1:
1. ema:Play Evaluation Kit with/without ema installed (see section 1.3 for device p/n’s)
2. OptConnect Gemini MIMO Antenna
3. 5VDC Power Supply
4. 2 x USB cables

2.3 Insert ema into ema:Play
If ema:Play includes an ema (see section 1.3 for device p/n’s), this section can be skipped.
To avoid damage to ema and/or ema:Play, take precautions to
correctly insert ema into the modem socket. Double check pin
alignment before applying power.
Follow this procedure to correctly insert ema into ema:Play.
1. Orient ema so that it’s label is aligned with the ema logo that is printed on the ema:Play PCB as
shown below in Figure 2.
2. Firmly press ema into the socket as shown in Figure 3.

2.4 Attach Antenna(s)
ema:Play includes two SMA to U.FL adaptors located at J3 and J12. These accommodate both a primary
antenna and a diversity antenna. The U.FL ends of these adaptors connects to ema’s X1 and X2
connectors. The SMA ends of these adaptors connect to the OptConnect Gemini antenna cables or other
antennas. If ema:Play includes an ema (see section 1.3 for device p/n’s), then the adaptors(J3, J12) should
already be connected to ema as shown in Figure 4.
Figure 4
Follow this procedure to correctly connect the adaptor’s U.FL end to ema if required:
1. Insert ema into ema:Play as shown in section 2.3.
2. Carefully bend the adaptor cables into position over ema’s antenna connectors (X1, X2) as shown
in Figure 4 above.
3. With extreme care, press the U.FL ends of the adaptor cables onto ema’s antenna connectors (X1,
X2). When correctly connected, there should be a subtle click/snap.
4. Confirm the connection by holding the adaptor cable close to ema’s antenna connectors (X1, X2)
and gently rotating the adaptor cable back and forth while it is connected to ema. It should rotate
freely in a flat planar fashion.
Note: If the antenna adaptor cables are to be removed, it is highly recommended to use an antenna
removal tool to avoid damaging the antenna connectors. Sample tool p/n: Hirose U.FL-LP-N-2
Follow this procedure to correctly connect the OptConnect Gemini antenna to ema:Play:
1. On the Gemini antenna, locate the cable labeled “LTE-1”. Finger tighten this cable onto ema:Play
at connector J3, labeled “Primary” as shown in Figure 5.
2. The other cable is labeled “LTE-2”, and should be finger tightened onto ema:Play at connector J12
labeled “Diversity” as shown in Figure 5.

2.5 Apply Power to ema:Play
1. Apply power to ema:Play and ema by plugging in the provided power supply at connector J9 as
shown in Figure 6. The following conditions can be observed and validate that the demonstration
project is successfully running:
•Green ema:Play power LEDs ON; 4V0, 3V3
•Blue ema:Play LEDs signal array is scrolling; D14-D17
Figure 6
2. Press and hold button SW7(shown in Figure 7) for about 2 seconds or until the LED signal array
changes to D14 blinking. The following conditions can be observed and validate that ema is
connected and communicating on the cellular network. Allow up to 30 seconds for these
conditions to occur.
•Amber ema:Play status LED ON; STS
•Green ema status LED ON; D1

3. OptConnect Summit Portal
3.1 Overview
The OptConnect Summit portal is an online tool that allows users to manage and monitor their entire fleet
of OptConnect cellular devices, and is included with the purchase of any OptConnect device. This section
describes how to use the Summit portal for basic ema monitoring and management. This section
assumes that the users’Summit account has been setup successfully, and the user can login to the
Summit portal. For questions regarding Summit account creation and login credentials, refer to section
1.2.
3.2 Login and Find ema
1. Continuing from section 2.5, confirm that ema:Play and ema are powered ON.
