Regulatory Requirements / Exigences Réglementaires
WARNING:
To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 23 cm or more 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 used for this transmitter must not be co-located in conjunction with any other antenna or transmitter.
WARNING:
Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received including interference that may cause undesired operation.
WARNING:
Changes or modifications not expressly approved by Microhard Systems Inc. could void the user’s authority to operate the equipment. This device
has been tested with UFL to Reverse Polarity SMA connectors with the antennas listed in Appendix A When integrated in OEM products, fixed
antennas require installation preventing end-users from replacing them with non-approved antennas. Antennas not listed in the tables must be
tested to comply with FCC Section 15.203 (unique antenna connectors) and Section 15.247 (emissions).
WARNING:
MAXIMUM EIRP
FCC Regulations allow up to 36 dBm equivalent isotropically radiated power (EIRP). Therefore, the sum of the transmitted power (in dBm), the
cabling loss and the antenna gain cannot exceed 36 dBm.
WARNING:
EQUIPMENT LABELING
The FCC and IC numbers depend on the model of the radio module. Do NOT use the Marketing Name of the product but the Model to distinguish
the Certifications Numbers. This device has been modularly approved. The manufacturer, product name, and FCC and Industry Canada
identifiers of this product must appear on the outside label of the end-user equipment.
WARNING:
This device complies with Industry Canada’s license-exempt RSSs. Operation is subject to the following two conditions:
(1) This device may not cause interference; and (2) This device must accept any interference, including interference that may cause undesired
operation of the device.
SAMPLE LABEL REQUIREMENT / EXIGENCE D'ÉTIQUETTE: px2
FCCID: NS915PX2
IC: 3143A-15PX2
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference,
and (2) this device must accept any interference
received including interference that may cause

other antennas provided the sum of the MPE ratios for all the other simultaneous transmitting antennas incorporated in a
host device is < 1.0 - 0.238 < 0.762. The following co-location were evaluated for mobile configurations:
1. EUT with 2 dBi dipole antenna co-located with Data Card Module (FCC ID RI7LN930, IC: 5131A-LN930)
2. EUT with 2 dBi dipole antenna co- located with LTE Data Transmitter Module (FCC ID R5Q-TOBYL100, IC

3. EUT with 2 dBi dipole antenna co- located with GSM/UMTS/LTE Data Module (FCC ID XPYTOBYL200, IC
8595A-TOBYL200)
Co - localisation avec Cellular Modem
Le maximum calculé rapport EMT pour l'EST avec antenne dipôle 2 dBi est de 0,238 , cette configuration peut être co-
située avec d'autres antennes à condition que la somme des rapports MPE pour tous les autres antennes de transmission
simultanées incorporés dans un dispositif hôte est < 1,0 à 0,238 < 0,762 . Le co- emplacement suivant ont été évalués pour
les configurations mobiles :
1. EUT avec 2 dBi antenne dipôle co-localisé avec module de carte de données ( FCC ID RI7LN930 , IC : 5131A
- LN930)
2. EUT avec 2 dBi antenne dipôle co- localisé avec LTE données Module émetteur ( FCC ID R5QTOBYL100 , IC

2.0 Quick Start
To reset to factory
defaults, press and
hold the CONFIG for 8
seconds with the pX2
powered up. The pX2
will reboot with factory
default settings.
This QUICK START guide will walk you through the setup and configuration of a few
basic applications. The QUICK START will rely on the WebUI for configuration. This
walkthrough also assumes the units used are installed in microhard interface/
development boards or custom boards that allow access to the LAN port. See the
appropriate section for pin-outs.
Note that the units arrive from the factory with a Radio Configuration of ‘Access
Point’ and the Local Network setting configured as ‘Static’ (IP Address
192.168.168.1, Subnet Mask 255.255.255.0). DHCP is enabled by default, and will
assign an IP to a connected device.
2.1 Getting Started
 Connect an appropriate Antenna to the ANTENNA connector of the pX2.
 Connect and/or apply a suitable power source to the unit.
 Connect A PC to the LAN port (eth0) of the pX2, using an Ethernet Cable.
 The PC must have its Network Setting (TCP/IP Properties) set to DHCP (The mo-
dem will assign a IP address to you), or STATIC with an IP Address of (e.g.)
192.168.168.10 and a Subnet Mask of 255.255.255.0.
The factory default
network settings:
IP: 192.168.168.1
Subnet: 255.255.255.0
Select Internet Protocol (TCP/IPv4)
and then Properties.
To set a Static IP, in Windows 7 the TCP/
IP Properties can be found in:
Start > Search Bar “Network and Sharing
Center”
Select “Change Adapter Settings” on the left
menu, and the right click the Ethernet
adapter connected to the pX2.

2.2 Simple Access Point and Station/Client
This Quick Start example requires (2) pX2 modules, one will be configured as a
Access Point (AP), the second unit will be configured as a Station/Client (ST). This
example will show the basic steps required to set up each unit so that a simple net-
work will be established.
2.2.1 Configuring the Access Point
 Use Section 2.1 Getting Started to connect, power up and log in to a pX2 unit.
 Give the pX2 unit a unique IP address.
AP ST
Wireless
Select Network from the top/main
navigation.
Select LAN from the submenu list,
and then select Edit.
Choose Static IP for the Connection Type.
Enter the following Network Information:
IP Address: 192.168.168.11
IP Subnet Mask: 255.255.255.0
Click on the Submit button to write the changes to the pX2. The Cancel button will re-
vert back to last values saved to the unit.
Once the IP Address is changed, you will need to type the new address into
your browser to continue the configuration.
To connect to an
existing network,
contact your Network
Administrator for valid
network settings.

For bench or close proximity testing it
is best to use a lower power setting to
prevent RF saturation. Select 20dBm
from the TX Power setting.
The remaining settings in the
Wireless menu should be left as
defaults for this exercise.
Click on the Submit button to
write the changes to the pX2. The
Cancel button will revert back to
previously saved values.
If any additional
settings need to be

2.2.2 Configuring the Station/Client
The following procedure describes the steps required to set up a pX2 unit as a Sta-
tion/Client (ST). A Station provides a single wireless connection (i.e to an Access
Point) and provides a wired connection to a PC or other devices.
 Use Section 2.1 Getting Started to connect, power up and log in to a second
pX2 unit.
 Give the pX2 a unique IP address.
To connect to an
existing network,
contact your Network
Administrator for valid
network settings.
Choose Static IP for the Connection Type.
Enter the following Network Information:
IP Address: 192.168.168.12
IP Subnet Mask: 255.255.255.0
Default Gateway: 192.168.168.11
Click on the Submit button to write the changes to the pX2. The Reset button will
revert back to last values saved to the unit.
Once the IP Address is changed, you will need to type the new address into
your browser to continue the configuration.
Select Network from the top/main
navigation.
Select LAN from the submenu list,
and then select Edit.

2.2.3 Testing the Connection
 Visually check to see if the pX2 units are communicating.
 With the PC connected to the Access Point (AP), type in the IP address of the
Station (ST) into the URL address bar of your browser. You should be able to
connect, log in and view the WebUI of the Station via the wireless connection.
If any additional
settings need to be
changed, ensure they
are also changed on
the Station/Client.
The RSSI LED’s represent signal strength, the more LED’s that are illuminated, the
stronger the signal. The Wireless > Status window also has a Connection Status sec-
tion as seen below:
RSSI LED’s that are
‘cycling’ or ‘scanning’
indicate that the unit
is searching for a
signal.
