2.0 Quick Start

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.

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.

The factory default network settings:

IP: 192.168.168.1 Subnet: 255.255.255.0

 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.

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.

Select Internet Protocol (TCP/IPv4) and then Properties.

2.0 Quick Start

Select Use the following IP address and enter the values below as shown:

IP Address: 192.168.168.10 Subnet Mask: 255.255.255.0

The factory default network settings:

IP: 192.168.168.1 Subnet: 255.255.255.0

The factory default login:

User name: admin Subnet: admin

It is always a good idea to change the default admin login for future security.

Click OK

 Open a Browser Window and enter the IP address 192.168.168.1 into the ad-

dress bar.

 The pX2 will then ask for a Username and Password. Enter the factory defaults

listed below.

 Once successfully logged in, the System Summary window will be displayed.



192.168.168.1

The Factory default login:

User name: admin Password: admin

2.0 Quick Start

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 network 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.

Select Network from the top/main navigation.

Select LAN from the submenu list, and then select Edit.

To connect to an existing network, contact your Network Administrator for valid network settings.

3.0 Hardware Features

Config Button:

The Config button on the pX2 can be used to either reset the modem into its factory default configuration, or it can be used to perform a firmware recovery procedure.

Factory Default Settings: While power applied and the pX2 in an operational state, press and hold the Config Button for 8-10 seconds or until the module reboots. It will reboot with the factory default configuration settings.

Firmware Recovery: To load the firmware on the unit it is recommended to use the normal WebUI to perform a firmware update (Maintenance). In the event that the firmware cannot be loaded using the standard WebUI (non responsive unit), pressing and holding the Config Button while powering-up the module will force the pX2 into a firmware recovery mode. There are 3 main modes, HTTP, TFTP and Master Reset. The table below shows the time required to hold the Config button while power is applied:

HTTP Recovery: Set an IP on a PC to 192.168.1.1. Open a web browser and Navigate to

192.168.1.39. This will open a simple webpage which will allow a firmware file to be loaded.

TFTP Recovery: Set an IP on a PC to 192.168.1.1. Use a TFTP session to push the firmware file to the modems recovery IP of 192.168.1.39. See Appendix for Firmware Recovery Procedure.

Master Reset: Runs Master Reset, file system is erased.

RS232 Serial:

The RS232 Serial data port can be used to communicate with RS232 Serial devices or it can be configured to operate as a console port. See Table 3-3 for pin assignments.

CPU/Status:

The CPU/Status LED indicates that power has been applied to the module. A Solid LED indicates normal operation, while flashing indicates boot or firmware upgrade status.

TX/RX LEDs:

The TX/RX LEDs indication wireless traffic to/from the pX2 module.

RSSI LEDs:

The RSSI LEDs indicate the Received Signal Strength on the Wireless Link. On a Access Point it will indicate an average RSSI value based on connected units. On a Client/Station the RSSI LEDs will represent the signal strength between the Station and the AP it is connected to. (The more LEDs illuminated, the stronger the signal)

Vpa 3/5V:

The Vpa jumper allows the radio inside the pX2 to be connected to 3.3 or 5VDC. For the pX2 to operate at maximum output Transmit (Tx) power of 1 Watt (30dBm), the Vpa jumper must be set to 5VDC (Pin 5+6).
