2 Introduction
Microkit Wi-Fi Gateway device is designed to Wi-Fi enable MGL iEFIS
It connects to MGL iEFIS (Challenger with iBOX, LITE, and MX1) using
RS232 port and offers
● Flight Plan Transfer using WiFi
● ADS-B (IN) for weather/traffic/airport data if connected to GDL-90
external ADSB Receiver.
● Other files format (once iEFIS firmware is updated)
The Wi-Fi Gateway for MGL offers a built-in browser interface to transfer
files. Once connected to the Gateway Wi-Fi access point, users are able
to use any browser to transfer/upload files, which in turn are pushed to the
connected EFIS.
Support for several EFB Apps to allow for direct flight plan transfer from
these Apps is underway, and users are able to update the gateway
firmware using the WiFi interface.

4 Installation
4.1 Wiring
The unit is supplied with a 4-wire quick-disconnect waterproof
connector.
RED
Aircraft Power (+12V/+24V)
GREEN
Aircraft GND (Use same point as iEFIS GND)
BLUE
WiFi Gateway TX (Connect to iEFIS RX pin)
YELLOW
WiFi Gateway RX (Connect to iEFIS TX pin)
Shielded 24 AWG wires are suitable.
It is recommended that the Gateway be installed behind the panel
next to the back of the MGL iEFIS. If it is required to extend the
wiring to reach MGL, use 24 AWG Aviation wiring and the length
should not exceed 25 ft of wiring for RS232 connection. Connect
the RS232 cable shield to a ground point from one end.
For Gateway GND (ground), use the same point/location connected
to the iEFIS GND. The Gateway does not require its own Circuit
Breaker, it can be shared with non-essential equipment such as USB
Chargers or others. If a dedicated Circuit Breaker is going to be
used, use a 1A circuit breaker or inline fuse.

4.2 Mounting
The Gateway unit includes mounting flanges.
As the Gateway is very light, it can be secured with cable ties to any
location, at any direction/orientation. It can also be secured to a
bundle of wires; do not secure the Gateway to a bundle of wires if
the bundle contains high current cables such as Alternator cable,
large Battery cable or strobes wiring.
5 Wi-Fi Connection
The WiFi Gateway for MGL uses a Wi-Fi
connection to allow connecting to the ADS-B IN
Receiver and to perform Flight Plan Transfer.
Use your device Wi-Fi Search and look for
GW_xxxxx. The xxxxx is the unique serial
number of the unit.
The default Wi-Fi Password: wifigateway
The Wi-Fi System is designed for the Phone
screen, but can be used with PCs/Laptops and
Tablets such as iPads.

Once connected, use your device Browser (Safari / Chrome / others) to
connect to the system. Input 192.168.11.1 on the browser.
Note: This local Gateway IP can be changed in the event an ADS-B
Receiver is using the same network range (192.169.11.x).
6 Wi-Fi Menu
6.1 Main Page
Once connected, the main page shows the
main menu.

6.2 EFIS File Transfer
Use this button to select a flight plan file to
be sent to MGL iEFIS. This currently
supports GPX, FPL or native ERT MGL format. Other files can also be
sent when supported by iEFIS firmware.
6.3 WiFi Options & ADS-B
ADSB WiFi Scan button allows searching for
the ADSB Receiver and then connecting to it.
Once connected successfully, the WiFi
Gateway always tries to connect to this ADSB
Receiver once powered and keeps trying
continuously every 30 seconds if it was not
initially detected or found (such as if the
Gateway is powered before the ADSB
Receiver).
See Section 7 (Usage Notes) for operation when
an ADSB Receiver is connected to the Gateway.
Reset ADSB WiFi button deletes the saved
ADSB Receiver connection details in the event
that the previously selected ADSB Receiver is
no longer available.

ADSB Stats button shows statistics of the
number of ADSB messages received since
current power on. (if connected to an ADSB
Receiver)
See Section 7 (Usage Notes) for operation when
an ADSB Receiver is connected to the Gateway.
Own WiFi Options buttons allow changing the local Gateway network
name & password, changing the local IP, and
resetting the local WiFi name/password to
factory default.
When changing the password, make sure
at least one of your devices (phone or
iPad) saves the new password and can
connect to the unit again without asking
for the password. If you forget the new
password, the only way to reset it is either by using a device (phone
or iPad) that already saved the password and reset using this page or
by returning the unit back for firmware re-programming. We have
no way of knowing your new password if you are unable to
connect to the unit.

6.4 Gateway Firmware Update
The firmware for the WiFi Gateway can be
updated using this button once new features
and enhancements are made available.
7 Usage & Notes
Using MGL menus iEFIS Menu→System setup menu→Serial Port
routing/allocations. Select Data/file server option for the used RS232 Port.
Once the Gateway is hard-wired using the configured Data/file Server
RS232 Port to an MGL iEFIS; iEFIS menu shows the Gateway IP by going
to MGL:
iEFIS Menu→System setup menu→Setup LAN, WIFi and Wires
Click on the “Microkit WiFi Gateway details” to see the IP of the Gateway
(our Free iOS App also shows the Gateway IP when transferring a flight
plan.

REF: WR2_REV_1.1

“Accept Flightplans” also needs to be selected. Other file formats are
also shown. Some or all of the other files options are not currently
accepted by the current iEFIS firmware and will be available as new
firmware is released.
7.1 Stand-Alone (Not connected to an ADS-B Receiver)
The WiFi Gateway for MGL creates a built-in WiFi Network (SSID) that
allows devices (Phones / Tablets / PCs) to connect to this WiFi network
and be able to use any browser (Chrome / Safari, etc.) to open the menu
for configuration and File Transfer to MGL.
The default IP for the Gateway is 192.168.11.1 unless configured
differently.
7.2 Dual-Mode (connected to an ADS-B Receiver)
The WiFi Gateway for MGL supports all ADS-B Receivers that transmit
GDL-90 protocol data.
Once configured to connect to an ADS-B Receiver; the Gateway becomes
part of the ADS-B Receiver network. This means other devices such as
Phones/Tablets/PCs that are also connected to the ADS-B Receiver WiFi
network are also part of the same Gateway network and able to connect to
the Gateway menu using the Gateway IP provided by the ADS-B Receiver.
The Gateway IP that is part of the ADS-B Receiver network can be seen
using the MGL menu as mentioned above. This IP normally does not
change once all devices are connected to the ADS-B Receiver WiFi
network.
The WiFi Gateway still maintains its own local network at the same time
and users are able to switch to that network if desired however, it is
recommended to remove the Auto-Join settings for the Local Gateway
WiFi network so all your devices stay connected to the ADS-B Receiver
WiFi network as this is the intended operation to also be able to receive
ADS-B data on these devices as well.

7.3 EFB Apps Integration
A free Microkit iOS App is available to allow for direct flight plan transfer
from iOS EFB Apps such as ForeFlight and any EFB that shares an FPL
flight plan. Check our website or MGL dealer website for a link to the iOS
App.
Ask your MGL dealer for other EFB Apps.
