3.1 Assemble Your mangOH—Detailed Steps

To assemble your mangOH Red HL78xx kit:

1. Verify the SW401 dipswitch pins are set correctly:

a. Remove the protective film from the dipswitches:

b. Make sure the dipswitches are set as follows:

· ON—1,4

(Set 5 ON if you want to enable backup battery charging.)

· OFF—2,3,5,6,7,8

For switch details, see Dipswitch Settings on page 24.

2. Insert a micro-SIM in the slot on the bottom side of the mangOH Red. (Either the micro-SIM included with the
kit, or one that has been activated by another mobile network provider.)

Note: If you do not have an activated micro-SIM, you can continue the tutorial, but will not be able to complete Connect to

a Mobile Network on page 14 and Register Your mangOH Red on AirVantage on page 17.

3. Attach the main antenna.

Tip: If you have trouble connecting the antenna, make sure it is positioned directly on the connector and push straight down.

The antenna will not connect at an angle.

Remove these screw posts if the serial cable also has screw posts.

4. Move the power select jumper onto the pins closest to the CONSOLE USB connector. (In this guide, power is
supplied from the dev machine’s USB port to this connector when you connect it in a later step.)

Note: The mangOH Red has two USB connectors. With an HL78xx installed:

• CF3 USB is used for power. (The connector will be less accessible than the CONSOLE USB when the kit is fully

assembled.)

• CONSOLE USB is used for power, and enumerates a serial COM port, however the port is not usable.

5. If your USB-Serial cable has screw posts on the serial end, you must remove the screw posts from the
UART-RS232 IoT card.

Rev 1 4/16/19 10 41113251

Mounting screws

6. Insert the UART RS232-4W IoT card in the IoT connector.

7. Insert the two M2x4 Phillips-head screws into the mounting blocks to firmly secure the IoT card.

8. Connect the USB-Serial converter cable to the DB9 connector on the IoT card and to a USB port on the dev

machine.

Power LED

9. Power up the mangOH Red:

a. Use a micro-USB cable to connect the CONSOLE USB connector to a USB port on the dev machine.

When the mangOH Red is powered, the Power LED turns solid green.

Tip: If the Power LED does not turn on:

• Make sure the cable is securely connected to the correct USB port (as shown in the image).

• Make sure the jumper block is on the correct pins (as shown in the image).

Note: For future reference, the mangOH Red’s power supply (USB port on your dev machine, or an AC adapter)
connects to the board via either USB connector—CF3 USB or CONSOLE USB (depending on the jumper position on
the power header).

[ 15.165647] usb 3-2: FTDI USB Serial Device converter now attached to ttyUSB1

10. Wait for the device to enumerate (< 30 seconds, typically)

You can confirm the device has enumerated by viewing Display Manager — two USB Serial Ports will enumer­ate for the Console USB connection and the IoT card:

11. Confirm that the connection between the computer and mangOH Red (via the IoT card) is functioning
correctly:

a. Connect to the mangOH Red via the enumerated USB Serial Port for the IoT card— Use a terminal

emulator package (e.g. PuTTy, Tera Term, Hyperterm) to open a serial connection. (Baudrate=115200,
Data bits=8, Parity = None, Flow control= XON / XOFF)

b. Type "at" and press Enter. The response "OK" should appear.

If nothing (or garbage) appears when you type, make sure the connection settings (baudrate, data bits,
parity, flowcontrol) and try again.
If "at" still does not appear, you may be connected to the wrong port. Close the connection and repeat
step a with the correct port.

Now you are ready to Connect to a Mobile Network on page 14.

Rev 1 4/16/19 13 41113251

4: Connect to a Mobile Network

Note the location of
the notched corner.

Inserted in bottom part of slot

In this chapter, you will make sure the mangOH Red can connect to the mobile network (for your SIM provider).

To connect to a mobile network, you must have a micro-SIM in the mangOH Red.

1. If you do not have a micro-SIM in the mangOH Red, insert one before continuing:

a. Disconnect power from the mangOH Red (remove the jumper from the power header, or unplug the

micro-USB cable that is providing power).

b. Insert a micro-SIM in the slot on the bottom side of the mangOH Red. (Either the micro-SIM included with

the kit, or one that has been activated by another mobile network provider.)

4

c. Reconnect the power (plug in the micro-USB cable or insert the jumper on the power header on the same

pins it was removed from in step a. The Power LED will light immediately.

Note: You must disconnect the power before switching SIMs so the mangOH_Red can detect the SIM while powering on.

d. Go back to Step 10 on page 13 and, after finishing the procedure, continue to Step 2 below.

2. You must be using an activated SIM for the radio to successfully register on the mobile network.

If you are using:

· the Sierra Wireless SIM provided with the kit (the SIM is not activated), you must activate it via AirVantage

(in the next chapter). Get the SIM information you will need for activation:

i. Get the SIM’s ICCID, and the mangOH Red’s IMEI and FSN:

AT+CCID?

AT+KGSN=0

AT+KGSN=3

· an activated SIM— Continue to the next step.

· a non-activated SIM— Activate the SIM with your provider, then continue to the next step.

3. Determine which APN to use for your SIM:

· Sierra Wireless (included with kit)—internet.sierrawireless.com

· Others—Check with the mobile network provider, or search the Internet for "<provider> APN". For

example, "Rogers Wireless APN"

Note: If your mobile network operator uses different APNs for 3G and LTE, make sure to use the correct APN for your CF3
module type. (e.g. WP8548 is a 3G module, and WP7603 is an LTE module.

4. You can now use your mangOH Red with your activated SIM. Refer to the AirPrime HL78xx AT Commands
Interface Guide available at source.sierrawireless.com for available commands. For example, to establish and
test a data connection using the Sierra Wireless SIM (and then close the connection), you can use the
following command sequence (refer to the guide for expected responses and notifications):

AT+CGDCONT=1,"IPV4V6","internet.sierrawireless.com"

6: Tips

6.1 Finding your SIM’s APN

Your SIM provider should give you the APN that you use to connect to their network. If you don’t have the APN,
you should be able to find it online.

If your mobile network operator uses different APNs for 3G and LTE, make sure to use the APN for the correct
network based on your CF3 module type (e.g. WP8548 is a 3G-only module—the APN for the network operator’s
3G network should be used).

Examples:

· Sierra Wireless— internet.sierrawireless.com

· Rogers Wireless— internet.com (GPRS); ltemobile.apn (LTE)

· Others—Search the Internet for "<provider> APN". For example, "Rogers Wireless APN"

8: Removing/Inserting an HL78xx Module

8.1 Removing an HL78xx module

To remove an HL78xx module from the mangOH Red:

1. Remove the module cover using the module cover removal tool— Starting at one corner, insert the tool in the
pair of holes and carefully pry the cover away from the module.

2. Repeat at the other locations (pairs of pry holes are on each side).

8

3. Lift the cover off the module.

4. Tip the mangOH Red over to drop the module and spacer out of the socket.

Rev 1 4/16/19 25 41113251

8.2: Inserting an HL78xx module

Make sure the face with the
’lip’ is at the bottom. This willl
guide the HL78xx module
into its proper position.

The circle on the module
matches the position of the
triangle on the socket.

8.2 Inserting an HL78xx module

To insert an HL78xx module on the mangOH Red board:

1. Insert the module spacer in the socket— Make sure the face with the smaller opening is at the bottom.

2. Insert the HL78xx module—Hold the module above the socket and line up the circle on the module with the

triangle on the socket. The module will drop straight into the socket. (Position matters!)

Rev 1 4/16/19 26 41113251

8.2: Inserting an HL78xx module

The circle on the cover
matches the position of the
