1 Introduction
1.1 Purpose and Scope
This document describes the commissioning and normal usage procedure for the WAPS beacon.
This version of the hardware interface through a TCP socket server is derived from an existing
version of the socket server interface that is being used for the Tiger beacon and hence there
may be some references to the Tiger beacon.
2 Architecture
2.1 Hardware Architecture
The hardware architecture of the WAPS Beacon system and the subsystem is described in the
following diagram. It is imperative the user understands that architecture before using the
socket server interface.
The connectivity architecture related to the socket server is illustrated in figure below:

Although it is shown that the IP address is static, just so that multiple ZEUS systems can be
connected on the same network, for developmental purposes, we can leave the IP addresses to
be DHCP. One would have to connect a console to the ARM CLI to determine its assigned IP
address.

3.4 TX Antenna mounting
Omni antenna to be installed on tower or roof top construction as defined in site specific
construction drawing. As a general rule on any monopole installations the TX antenna shall be
attached to a 6 foot side arm mount, minimum distance away from the monopole unless the
antenna extends above the monopole in its entirety. Likewise the antenna shall be kept a
minimum distance of 6 feet from any other vertical structures on other types of towers. For roof
tip installations, the TX antenna must extend above all parapet walls and penthouses on the
roof top.
This radio transmitter may only operate using a vertically polarized antenna with maximum gain
of +8 dBi. To reduce potential radio interference to other users, the antenna gain should be so
chosen that the equivalent effective radiated power (ERP) does not exceed 30 Watts.
Antenna Type: Monopole
Polarization: Vertical
Maximum Gain: +8 dBi (maximum gain of antenna + cable loss is 3dBd)
A CSV file (configuration file) per transmitter is created by the NOC engineer, based on the
installation parameters such as line lengths, antenna type etc.
The TX output power level setting is contained in the CSV file.
The output power is adjusted by the “attenuation” setting. This value in the CSV file is
calculated by a formula to set the output power (not to exceed 30W EIRP). The variables used in
the calculation include PA Gain (Gpa), TX Antenna Gain (Gant), TX filter insertion loss (ILflt),
internal cable loss (ILint), external cable loss (ILext), and transceiver output power (PTCVR).
EIRP (W) = 10^((PTCVR •] ILint + Gpa •] ILflt •] ILext + Gant) / 10) / 1000
This radio transmitter (FCC ID: A4P-100-0007-01) has been approved by FCC to operate with
the antenna types listed below with the maximum permissible gain and required antenna
impedance for each antenna type indicated. Antenna types not included in this list, having a
gain greater than the maximum gain indicated for that type, are strictly prohibited for use with
this device.

3.5 Connecting to the Power System
1. Open the Power System door
2. Switch the circuit breaker switches to the “off” position if not already.
3. Connect the HRS0016 cables
4. Plug in the power chord of the WAPS Beacon and switch on the MAIN switch in the
battery compartment
5. Verify that the GND tab is broken off and Battery switch is in the OFF position.
6. Verify that the Rectifier MiniPACK LED’s all go to green.
7. Verify that the MiniPACL controller display is on
8. Flip all three circuit breaker switches from step 3 to the ON position simultaneously.
9. Verify that the following LEDs are lit indicating operation:
a. Ethernet Switch: Phoenix Contact power and ports (all connected ports are lit)
b. EVDO modem (Raven)
10. Test the Battery backup
a. Flip Battery switch to the “ON” position
b. Flip the Main Switch from step 4 to the OFF position.
c. Verify all LEDs from step 7 are lit.
d. Flip the Main switch back to the ON position.
11. Connect the EvDO antenna cables to the EvDO Tx port. In cases of sites which have been
documented as requiring EvDO diversity, connect the diversity antenna to the EvDO DIV
port. In cases of sites which have been documented as needing a POTS line, connect the
phone line to the ‘TELCO’ port.
12. Connect the field service laptop with an Ethernet cable to the ‘Ethernet’ port on in the
Phoenix switch port #5. Wait for a few seconds to get an IP address on the field service
laptop. Try and browse the internet to ensure connectivity. Once connectivity is
ensured, call the operator at the NOC to further commission the beacon box.

4 Usage Model
4.1 Hardware Connections for the Server
The socket server expects the following modules to be connected to the Zeus board
- PA module
- GPS Module
- Rubidium
- Weatherboard
Socket clients communicate with the Socket Server running on zeus over the Ethernet
link as shown in figure below. For developmental purposes, multiple zeus setups can be
connected to the network as long as they have DHCP addresses. One computer on the
same network can be used to communicate with multiple Zeus systems using the
IPAddress:Port configuration.

Switch
Zeus1
DHCP
Zeus2

Router
4.2 Socket Server Startup
The socket server runs on the Zeus Board ARM Linux Kernel. To connect to the Zeus Board, use
an ssh client such as ‘putty’ from the GuiClient computer.

1. Login to the Zeus ARM Linux shell using the ssh client
2. Verify that the socket server is not already running
3. pgrep -fl Main.py # This command will show if the server is already running. If not
continue with the next steps
4. cd ~/apps/server
5. python Main.py –s /dev/ttyO1 > /tmp/Main.log &
4.3 Socket Client Installation
The socket client should be installed on the GuiClient computer. This machine can be a Windows
or a Linux PC (with X Windows) as long as python and svn are installed on the machine.
1. Download pythonxy from http://code.google.com/p/pythonxy/, full version (2.7.2.1).
During installation, make sure that PySerial is selected.
2. Download the Tortoise SVN client http://tortoisesvn.net/downloads.html (optional)
3. Unzip the client.zip zipfile on the GuiClient computer and change directory to the ‘client’
folder.
4.4 Socket Client Startup
1. On the client computer, start the ‘GUIClient.py’ script by double clicking on the
program. (or ‘python GUIClient.py’ in the case of Linux)
2. The above step will launch a window as shown in Figure 13. In the ‘Summary’ tab,
enter the IP of the beacon provided by the field technician and port number as
‘7734’.
3. Clicking on connect establishes a TCP/IP connection with the beacon and the
connect button changes to ‘Disconnect’ confirming a successful connection.
4. If step 4 fails and an error message ‘Could not connect to server’ is displayed then
debug for one of the following causes:
a) An error in IP/ port entered.
b) Ethernet connection issues.
c) The socket server script not running on the zeus platform.

4.4.3 Transmit Tab
Click on ‘Transmitter’ tab and follow the procedure below to program the transmitter
board.
Procedure to confirm PA connections and cabling:
1. Click on ‘Import from CSV’ to launch an explorer window as shown in Figure 16
and choose Beacon_test.csv’ located in the same client folder as the GUI.
Note: The Beacon_test.csv is a test parameters file with random LLA info and a
safe attenuation of 10dB to transmit well below 30W ERP. This is used to test the
PA power levels and confirm cabling between the TX and PA. The final
configuaration CSV files per transmitter are created by the NOC engineer based
on the installation parameters such as line lengths, antenna type.
2. Click ok to populate the parameters required for transmission and then click save
in ‘Transmission control’ section which programs the parameters listed in the
transmission control tab. The center frequency of operation comes up as
926.227MHz.

3. Clicking on ‘Disable C Band’ will change the text of the button to ‘Enable C
Band’. Clicking on it again enables transmission just in the C band with center
frequency as set in the transmission control section.
4. To enable dual band transmission, set ‘IF Freq’ to 2.727 in C band and -2.727 in B
band tabs. Repeat step 3 above for both disable C and B band buttons to enable
transmission in both the bands. Setting these numbers will set the center
frequency of operation for the transmitter in dual band to be 923.5MHz. No other
IF frequency offsets are accepted by the GUI.
5. Click on ‘Set WB to Basic mode’ which will start streaming pressure and
temperature data from the weather sensor connected to the transmitter board.
Make sure the pressure and temperature values change for 0,0 to valid
measurements.
6. Click on ‘Save all’ button to set the rest of the parameters on the transmitter board.
7. Clicking on ‘Start transmission’ will change the text to ‘Starting’ and after 5-10
sec once the board starts to transmit, the entire GUI panel will get disabled except
‘Stop transmission’.
