Regulatory Requirements
To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance
of 23cm or greater for the IPn4G utilizing a 3dBi antenna, or 3.5m or greater for the IPn4G
utilizing a 34dBi antenna, should be maintained between the antenna of this device and persons
during device operation. To ensure compliance, operations at closer than this distance is not
recommended. The antenna being used for this transmitter must not be co-located in conjunction
with any other antenna or transmitter.
This device can only be used with Antennas approved for this device. Please contact
Microhard Systems Inc. if you need more information or would like to order an antenna.
WARNING
WARNING
MAXIMUM EIRP
FCC Regulations allow up to 36dBm Effective Isotropic Radiated Power (EIRP).
Therefore, the sum of the transmitted power (in dBm and not to exceed +30dBm)), the
cabling loss, and omnidirectional antenna gain cannot exceed 36dBm.
WARNING

CSA Class 1 Division 2 Option
CSA Class 1 Division 2 is Available Only on Specifically Marked Units
If marked this for Class 1 Division 2 –then this product is available for use in Class 1, Division 2,
in the indicated Groups on the product.
In such a case the following must be met:
The transceiver is not acceptable as a stand-alone unit for use in hazardous locations. The
transceiver must be mounted within a separate enclosure, which is suitable for the intended
application. Mounting the units within an approved enclosure that is certified for hazardous
locations, or is installed within guidelines in accordance with CSA rules and local electrical and
fire code, will ensure a safe and compliant installation.
Do not connect or disconnect equipment unless power has been switched off or the area is
known to be non-hazardous.
Installation, operation and maintenance of the transceiver should be in accordance with the
transceiver’s installation manual, and the National Electrical Code.
Tampering or replacement with non-factory components may adversely affect the safe use of
the transceiver in hazardous locations, and may void the approval.
The wall adapters supplied with your transceivers are NOT Class 1 Division 2 approved, and
therefore, power must be supplied to the units using the screw-type or locking type connectors
supplied from Microhard Systems Inc. and a Class 1 Division 2 power source within your panel.
If you are unsure as to the specific wiring and installation guidelines for Class 1 Division 2
codes, contact CSA International.

2.0 Quick Start
This QUICK START guide will walk you through the setup and process required to
access the WebUI configuration window and to establish a basic wireless connection
to your carrier.
Note that the units arrive from the factory with the Local Network setting configured
as ‘Static’ (IP Address 192.168.168.1, Subnet Mask 255.255.255.0, and Gateway
192.168.168.1), in DHCP server mode. (This is for the LAN Ethernet Adapter on the
back of the IPn4G unit.
2.1 Installing the SIM Card
 Before the IPn4G can be used on a cellular network a valid SIM Card for your
Wireless Carrier must be installed. Insert the SIM Card into the slot as shown
below.
2.2 Getting Started with Cellular
 Connect the Antenna’s to the applicable ANTENNA jack’s of the IPn4G.
 Connect the power connector to the power adapter and apply power to the unit,
the RF & SGNL LED’s will flash during boot-up, once they stop, proceed to the
next step.
SIM Card Slot
To reset to factory
defaults, press and
hold the CFG button
for 8 seconds with the
IPn4G powered up.
The LED’s will flash
quickly and the IP4G
will reboot with factory
defaults.
Use the MHS-supplied
power adapter or an
equivalent power
source.
The unit can also be
powered via PoE using a
MHS PoE injector.

2.0 Quick Start
 Connect A PC configured for DHCP directly to the ETHERNET port of the IPn4G,
using an Ethernet Cable. If the PC is configured for DHCP it will automatically
acquire a IP Address from the IPn4G.
 Open a Browser Window and enter the IP address 192.168.168.1 into the ad-
dress bar.
 The IPn4G will then ask for a Username and Password. Enter the factory defaults
listed below.
192.168.168.1
The factory default
network settings:
IP: 192.168.168.1
Subnet: 255.255.255.0
Gateway: 192.168.168.1
The Factory default login:
User name: admin
Password: admin
The factory default login:
User name: admin
Subnet: admin
It is always a good idea to
change the default admin
login for future security.

© Microhard Systems Inc. 15
 Once successfully logged in, the System Summary page will be displayed.
 As seen above under Carrier Status, the SIM card is installed, but an APN has
not been specified. Setting the APN to auto (default) may provide quick network
connectivity, but may not work with some carriers, or with private APN’s. To set
or change the APN, click on the Carrier > Settings tab and enter the APN sup-
plied by your carrier in the APN field. Some carriers may also require a User-
name and Password.
 Once the APN and any other required information is entered to connect to your
carrier, click on “Submit”. Return to the System > Summary tab.
2.0 Quick Start
Auto APN: Introduced in
firmware version v1.1.0-
r1038, the IPn4G will
attempt to detect the
carrier based on the SIM
card installed and cycle
through a list of
commonly used APN’s to
provide quick network
connectivity.

© Microhard Systems Inc. 16
 On the Carrier > Status Tab, verify that a WAN IP Address has been assigned by
your carrier. It may take a few minutes, so try refreshing the page if the WAN
IP Address doesn’t show up right away. The Activity Status should also show
“Connected”.
 If you have set a static IP on your PC, you may need to add the DNS Servers
shown in the Carrier Status Menu to you PC to enable internet access.
 Congratulations! Your IPn4G is successfully connected to your Cellular Carrier.
The next section gives a overview on enabling and setting up the WiFi Wireless
features of the modem giving 802.11 devices network access.
 To access devices connected to IPn4G remotely, one or more of the following
must be configured: IP-Passthrough, Port Forwarding, DMZ. Another option
would be to set up a VPN.

2.3 Getting Started with WiFi
This Quick Start section walks users through setting up a basic WiFi AP (Access
Point). For additional settings and configuration considerations, refer to the appro-
priate sections in the manual. This walkthrough assumes all setting are in the fac-
tory default state.
2.3.1 Setting up WiFi
 Use Section 2.2 Getting Started with Cellular to connect, power up and log in
and configure the Carrier in a IPn4G.
 Click on the Wireless > Radio1 Tab to setup the WiFi portion of the IPn4G.

2.3.2 Connecting to WiFi
 Now that the IPn4G has connection to the Cellular Carrier (See Section 2.2) and
the WiFI has been set up (See Section 2.3), WiFi devices should be able to de-
tect and connect to the IPn4G.
 On a WiFi enabled PC/Device, the SSID of MyNetwork, that was created in the
last example should be visible. Connect to that SSID and enter the password.
 Once connected the status should change to connected, and network access
should be enabled.
