installinG and ConfiGurinG the system
A basic understanding of networking and the connected sub-systems is highly recommended
to ensure a smooth installation of this product. All systems connected should be installed
according to the respective manufacturer’s recommendations.
In addition, ensure qualied personnel are used to install equipment where required. For
example, a licensed electrical contractor will be required to install all line voltage devices
such as light switches, and a licensed security contractor will be required to install or modify
your security system.
The following is an overview of the basic steps in setting up a system for the rst time. More
detail is provided in the respective sections of this guide. It is important that you follow the
steps below in order to ensure the installation goes smoothly.
n Pre-wiring
9
Ensure all pre-wiring is in place, based on which sub-systems you intend to automate. Pre-
wire requirements for all sub-systems are detailed in the Cortexa Pre-Wire Guide, available
from www.cortexatechnology.com.
n installing sub-system deviCes
Physically install all sub-system devices. Here we are talking about security systems, lighting
devices, thermostats, irrigation modules, surveillance cameras, audio system.
Be sure to ensure all sub-systems and devices are working satisfactorily before you start
integrating them into your Cortexa distribution system, etc.
n ConneCting to the Cortexa 7202
Physically connect the RS232 connector for each of the following sub-systems (Security,
Lighting, Irrigation, HVAC, Audio), as applicable in your case, to a Com port on the back
of the Cortexa 7202. It does not matter which sub-system connects to which port, however
note which port each sub-system is connected to for the next step in the process. The only
exception to this is HVAC, which must be congured to Com1, 2, 3, or 4.
Version 2.2
Page 10
installinG and ConfiGurinG the system
Continued
n ConneCting the Cortexa to the network
This step establishes the Cortexa to your network and the accessibility to the Internet. In
most cases, the Cortexa will come plug and play out of the box, without requiring any
network conguration. If this is not the case, refer to Section 4, Initial Network Setup, for
more information.
n Configuring the sub-systems
From the Sub-System Setup tab on the Conguration Utility Page, congure each sub-system
to the Com port to which it is physically connected. Com ports are selected by clicking on
the drop down box beside the port. This will display all available Com ports. Simply click
on the Com port desired and the Cortexa will then recognize that particular sub-system.
n setting uP the sub-systems
Within each sub-system, all of its specic devices must then be added to the Cortexa. This
10
is a simple process, and varies by sub-system. Details on how to do this are provided in the
section of this Owners Guide pertaining to each sub-system. The following is an overview by
sub-system to help explain what information and conguration we are talking about here.
Security: Security zone information is entered into the Security Manager
HVAC: Each thermostat must be physically congured to have a unique address and
entered in the Device Manager
Lighting: Specic lighting devices are congured into Areas (Rooms) in the Cortexa
Device Manager
Irrigation: Irrigation zones are added to and labeled in the Cortexa Device Manager
Cameras: Names associated with each camera must be assigned and entered into the
Cortexa Camera Manager
Audio: Zone names and source names are congured into the sub-systems setup
page (advanced button)
IR Control: Infra-red (IR) codes are learned into the Cortexa Device Manager (IR), and
custom remote controls are congured in the Device Manager
Version 2.2

n writing events
When everything is congured in the Cortexa Conguration Utility, you are ready to start
writing events. This is the fun part, where the system starts to come alive and automate your
home. The extent to which you can have the system automate the sub-systems in your home
is limited only by your imagination and creativity, so many scenarios are possible.
The way to think about your new integrated home is that every device congured into
the Cortexa is “connected” to every other device. So, thermostats, lights, security zones,
cameras, audio, TVs/DVDs (through IR control) are “connected” – your vision of living in a
digitally connected home is becoming a reality.
Here is one simple example of the integration of the sub-systems. Think about all the things
you do when you go to bed at night; arm the security system, turn lights off, check garage
doors are closed, adjust thermostat(s), turn TVs and other devices off. With one simple event
11
in the Cortexa, just arming the security system will trigger all of these other things to happen
automatically, within seconds.
Event writing is simple; there is no programming language to learn. Events are written using
selections provided in drop-down boxes and we feel sure you will easily master writing your
own events.
Be sure to name your events logically so you can easily identify each event and remember
the function that each event performs.
There is a detailed section on event writing, including several sample events, in the Home
Management section of this Owners Guide.
Version 2.2

initial networK setup
n setuP your loCal area network (lan)
First, connect the broadband modem to the WAN port on the back of the Cortexa 7202.
A PC should then be connected to a port on a network switch, and the network switch
connected to the LAN port of the Cortexa. You will use standard Category 5, or better,
cables to do this. The link light for each port will be lit when you are properly connected
and all devices are turned on. A direct connection may also be made from the Cortexa LAN
to a PC, however this requires Cat5 crossover cable.
n start uP sequenCe
Power up your broadband modem rst and wait approximately one minute for it to
1.
complete diagnostics as indicated by the panel lights. If you have been connected
to another router previously, make sure to leave the modem power off for 1 to 2
minutes to refresh the router table.
After your modem is ready, start the Cortexa 7202 by pushing the power button.
2.
12
Wait approximately 2 minutes for the operating system to load.
Start your Computer. When ready, open your Internet Explorer web browser.
3.
n logging into the Cortexa
The Cortexa factory default settings issue DHCP addresses for the default gateway IP range
that is 192.168.10.100 to 192.168.10.150. If your computer is congured to receive a
DHCP address then you should have received an address in that range. If it is not congured
to receive a DHCP address, then you can manually set your IP address. Defaults for manual
TCP/IP conguration are as follows:
IP Address 192.168.10.x, with x being any number between 2 and 99
Subnet Mask 255.255.255.0
Gateway 192.168.10.1
DNS Server 192.168.10.1
Open your browser and enter the following into the address bar of your browser:
http://cortexa. This will take you to the login page. If not, try using http://192.168.10.1
If this does not work please see the troubleshooting section of this Owner’s Guide.

n Configuring the router
This section details how to congure the Router within the Cortexa to manage your network
and gain access to the Internet through your Internet Service Provider (ISP). Your ISP may
require the use of a Host Name and Domain Name. You will need this information from
your ISP. If you do not have this information, please contact your ISP before proceeding.
Document any changes from default by printing the page before saving, and making notes
of passwords that are not displayed.

Change Password
The password section allows the current user to change passwords. If logged in as admin,
this will change the admin password.
liCense keys
All access points other than a web browser require a License Key. All Cortexa access points
and access point software is shipped with a license key. This key is added in the License Keys
section of the Main Menu of the Cortexa Conguration Utility.
Click on the “+” button, enter the key and click Save. The key will then be added and
associated with the hardware device or software application. All keys are generic and
any key may be associated with any access point. Upon association, the parameters of the
access point will be listed; Key Date, Product, Version, IP Address, Report Date.
17
License keys may also be edited using the “e” button, or deleted with the “x” button.
n administration
The Administration section allows you to congure who has access to your Cortexa Home
Control system, and what permissions are allowed. This section is also used to update
rmware, and to backup and restore your settings.
user maintenanCe
Add a list of users that are allowed to access the Cortexa. This gives better security control
without having to give out the master password. This also provides the ability to determine
which, if any, of the conguration functions within the Cortexa each user may access.
baCkuP / restore
This section will allow you to back up and restore all of your settings. You should backup
your data after you have initially congured the Cortexa, and then at frequent intervals
thereafter. We recommend that you use the current date in the backup lename.
software uPdates
In our drive to continually improve this product, frequent software updates will be released.
All software updates are free to existing users, and easy to install. We want all users to
enjoy the latest software and the functionality and reliability it provides. First check to see

if new software is available by clicking the Check Now button. If a later release of rmware
is available, simply click the Update Now button. The new software will now be downloaded
to your Cortexa. This will take approximately one minute. You will then be prompted to
reboot the Cortexa. Upon reboot, the new software will be installed and running.
reboot system
Select reboot system and click YES. A reboot will take approximately one minute.
faCtory defaults
If you require to restore the factory defaults settings, click the YES button. You will clear all
current Cortexa settings and restore factory default settings.
n home management
event manager
18
Events allow the automation of all sub-systems and devices throughout the home, in a
completely integrated way. This section will cover the key parameters involved in event
writing, followed by some examples to illustrate their uses.
Writing events with the Cortexa system does not require the learning of a programming
language unlike many systems. At every step, the system presents the user with valid choices
from drop-down menus. Do not think this is complicated, or beyond you. Many of our
customers start off saying they will not write their own events, then actually do when they
see how simple it is. Events may be written and executed from anywhere you have access
to your Cortexa.
event user interfaCe
On the right is the Event page from the
Cortexa User Interface. From My Home,
you can view a list of all events within the
system, and run an event by pressing the
play button. You can also view the status
of an event, enable an event, or disable
an event. For example, you may have a
morning event that automatically turns on
music throughout the home at 6.30am every
weekday. On vacation days you may not want the event to run, so simply pressing disable
will stop the event from running until it is re-enabled.
Version 2.2
Page 19
Cortexa 7202 ConfiGuration utility
Continued
event management utility
Located in the Home Management section of the Cortexa Conguration Utility, the Event
Manager is used to create and modify events. To create an event, enter the desired event
name in the event description eld and click Add New Event.
Having created the event, you can then add a trigger (optional), case statements (optional)
and lines of macros to make the event carry out the desired function. You may rename or
delete events using the buttons beside the event name. There is also an option to hide or
show the event. If there is no need for the event to be visible on the main user interface, you
may want to hide the event in order not to have too many events on the user interface. This
is typically used for events that have a built-in trigger and will never require to be manually
triggered.
Events may be organized using the Organize Events function at the bottom of the events
19
page. To re-order an event, select that event in the left drop-down box, then select the
event above the desired destination from the right drop-down box. Click Move and the
event will immediately move to its new location. This will determine the order in which they
appear in the My Home user interface. You may wish to list events in alphabetical order, or
perhaps in the order of most frequent use.
Names, Triggers, Cases aNd aCTioNs
These are the four things to consider in event writing. Here’s what they are and how they
are used:
name
Each event must have a unique name. Be sure to name events with a name that indicates
what they do. For example, an event run before going to bed might be called “Goodnight”.
After a while you will have many events in your system.
Version 2.2
Page 20
Cortexa 7202 ConfiGuration utility
Continued
triGGer
Events may or may not have a trigger. The trigger is what will start the event running. There
are many possible triggers; time, sunrise/sunset, weather condition and so on. For example,
a lighting scene may be triggered by sunset. Most events have triggers. Without a trigger,
an event will only run when manually initiated. There are events where you will want this
to be the case. An example might be audio events. Other than perhaps turning on audio
when you wake in the morning, for the most part it will be a spontaneous decision to listen
to music throughout the home. But when that time comes, just start the event and the music
can be playing in every room, from the same or different sources, at the desired volume in
each room.
Case
Events may or may not make use of case statements. A case is a condition that will be tested,
then dependent on the outcome of the condition, the action will or will not execute. A good
20
example is with irrigation events. You have an event that turns on your sprinkler zones,
however you don’t want to water your yard if the wind is blowing at 25 mph just when you
are ready to water. The condition of the case would then be to check wind speed. We will
look at this specic example later in this section.
aCtion
All events will have at least one action statement. Without an action statement an event
would not perform any function. Action statements will typically involve one or more devices.
For example, turn light(s) on, set thermostat temperature, set audio source, record video
from a camera. There are also situations, such as having the system send you an email,
where no device is involved, however this is still an action.
Version 2.2
Page 21
Cortexa 7202 ConfiGuration utility

examples of eveNTs
Here we will look at four actual events to help you see how the above parameters work
together. In each case, we will explain what the event does, followed by screen shots and
some brief explanations of what each screen is doing. To create an event, simply go to
the Event Manager within Home Management, enter the name of the event in the Event
Description eld, and click Add New Event. You will then be able to congure the event
trigger, case and actions. Case and Actions are accessed through the “Edit Macro” button.
front door arChive
This event records video from a camera every time the front door is opened. Below is the
trigger. This is from the Security System, and specically the zone called Foyer Entry and
when the zone is tripped, i.e. the door is opened. Every time the door this opened, the
trigger will initiate this event.
21
Having established the trigger, we then think about whether we want to have a case condition.
In this situation, the answer is no. Every time the door opens, we want this to execute, so there
is no case involved. We then move to Action. This is where we tell the system what we want
the event to do, having been triggered.
On the next page, you will see that in this case, our action is “Stream Video Images”, i.e. start
the camera recording. The system then asks which video source. We select Front Door (the
name of the camera over the front door). The system then gives us the option to select the
number of frames and the frame rate. These will obviously determine the quality and length
of the recording. Here we have selected 100 frames at 250 milli second (one quarter of a
second) intervals. This will give us 25 seconds of good quality video.
Version 2.2
Page 22
Cortexa 7202 ConfiGuration utility
Continued
The event is now complete and looks simply like this.
22
This is not a very complicated event, however we hope you can see how simple and fast it
is to create, and not one line of programming code involved! When you become procient
with the system, events like this can be created in just a few seconds.
irriGation
This event turns on two zones of irrigation, however we care about the environment (and our
water bill), so have added some intelligence in the form of two cases.
Firstly, the trigger. This is time based; specically we want to irrigate three days per week.
The trigger type is Weekly, and as you can see we have entered our desired parameters in
terms of which days and what time we would like to start watering.
Version 2.2
Page 23
Cortexa 7202 ConfiGuration utility
Continued
We now click Edit Case. In this situation, our case is a Weather Condition. That condition is
based on Rain Fall. Since the Cortexa is collecting local weather data every fteen seconds,
not only does it know current weather conditions, it is also able to calculate historical data.
We decided our criteria to be based on 0.2” over the last three days.
We also added another case condition based on current wind speed. You will see that when
we look at the nished event.
23
Having established our trigger and cases, we are ready for action. The action is to water
the yard. The Action type is “Rain 8 Net”, the name of our Irrigation system. The Irrigation
module comes in 8 zone increments, each one having a unique address. The relay number
then corresponds to the irrigation zone. Here we are turning on zone 1, i.e. Address 1, Relay
1. As an example, zone 9 would be Address 2, Relay 1.
The following screenshot is the completed event. After each case statement, we selected
End Macro. End macro immediately halts the entire event, i.e. none of the actions commands
are executed. Obviously this is what we want here. If rst condition is true, i.e. the wind is
blowing at more that 15 mph, we do not want to water the yard, no matter what else is true
or false.
Version 2.2
Page 24
Cortexa 7202 ConfiGuration utility
Continued
The command “Sleep For” is used to let the sprinkler zone run. So for zone 1, we open it,
then the event goes to “sleep” for 10 minutes. After exactly 10 minutes, the event “wakes
up” and turns off that sprinkler zone.
24
sunset liGhtinG
This is a very simple event which we will use to highlight one of very useful features of
Cortexa event writing; the use of ags. Flags can be used within cases to add some form
of condition or additional intelligence to the event.
The event simply turns on our desired lights, to their desired intensity level, at sunset each
day.
Here we are using sunset as our trigger. We also have the option to set variances from
both sunrise and sunset. We have decided that we’d like the lights to come on before sunset
as at sunset it is already a little dark in the house. We can set variances + or – and with
hours, minutes and seconds. In this case we are telling the event to launch 10 minutes before
sunset.
Version 2.2
Page 25
Cortexa 7202 ConfiGuration utility
Continued
Our ag is called “Vacation”. Flags are setup up in the Flag Manager, again within Home
Management. Our vacation ag, as you might imagine, indicates whether we are home,
or on vacation. We would like a different lighting scenario to take place when we are on
vacation, i.e. less lights to come and not be wasteful of energy.
Flags have a value, which can set in the Flag Manager. They can also be modied by an
action in an event. In this case, we have the ag set up such that when we go on vacation
its value is 1, otherwise it is 0.
So let’s look at the event. Both “Lamp Scenes” and “Sunset” are pre-dened lighting scenes
that have already been set up. Line 0 in this event will always run, i.e. whether we are on
vacation or not, we want the lamps to come on.
Lines 1& 2 will run if we are on vacation (because the vacation ag will be set to 1), but
25
not if we are not.
Line 3 is the opposite of 1&2. It runs when we are home. This turns on lights throughout the
home, just as we want, but only if we are home!
To set the vacation ag, use a simple action statement as below.
Version 2.2
Page 26
Cortexa 7202 ConfiGuration utility

GoodniGht
This event runs last thing at night. We will use it to highlight another nice feature; the ability
to run an event from within another event. The trigger is the arming of the Security System
with any user code. If you have multiple codes, you can write events specic to the code
used to arm, or disarm, the system.
26
We have an existing event called “Audio Off” that turns off all audio throughout the home.
We’d like to do that as part of this event. Instead of having to write the actions for that
event again, we simply select “Control an Event”. The system then prompts us for the name
of the event from a drop-down menu with the names of all of our events. We select “Audio
Off”, then tell the system to start the event.
The entire event is below. After turning off our audio, we send commands to a TV, Receiver
and DVR to turn off. We then run another event that we have previously written, “Garage
Doors Close”. This event checks to see if all doors are closed and closes any that are open.
We then adjust three thermostats for comfortable sleeping temperatures, and nally run two
lighting actions to congure the lights how we like them during the night.

A useful event trigger is an IR command. Essentially any button on an IR remote control can
be set to trigger any Cortexa event. For example, an unused button may be “mapped” to
the “Goodnight” event, shutting the house down for the evening from one button press.
The event is very simple to congure, essentially just a trigger and an action. On the trigger
page, the Learn IR button is used to capture the trigger IR. With the IR receiver attached
to the Global Cache device in line of sight to the remote control, click on Learn IR then push
the remote control button to be captured. The IR string will then be populated in the space
provided. Click on save and the trigger is complete. As with any other event, select the
desired action to be triggered. The event will now run every time the IR receiver detects
this IR command.

BuildiNg a CorTexa remoTe CoNTrol
Building a remote control customized to your needs is easy with the Cortexa’s Remote
Control Designer. First go to Add Devices, add a Remote and associate it with the room of
32
your choice. Then go the Edit Devices, and beside the entry for that remote you will see a
button labelled Designer. This takes you into an application to congure a Cortexa Remote
Control.
Select View Mode. The rst selection is for both Media Center and a web browser, and the
second for a touch panel or webpad. These selections adjust the real estate available to
position remote buttons.
Below is an example of a remote controlling multiple components; TV, receiver, DVD, DVR,
PC, all from one single screen. Some of these buttons will send a single IR command to a
component, while others will execute an event.
The remote designer is very exible
with numerous variable parameters
to tailor buttons based on personal
preference; horizontal and vertical
positioning, size, text, font size and
color. Buttons may be dragged and
dropped anywhere on the screen.
Note: it is recommended that you
save the remote as you build it,
and obviously save it at the end of
the design.
Version 2.2

The Designer is highly intuitive and allows you to add buttons, either custom labeled or xed
such as Power, then drag and drop them to the desired position on the screen. You can
program any button to associate with any IR string you have learned, as above. Also, not
only can the remote activate an IR command string, it can also initiate any Cortexa event.
For example, in a home theatre setting, you might have an event that turns on a DVD player,
sets the channel on a receiver, dims lights and adjusts thermostat settings. This event could
then be activated by a “DVD” button on the custom remote. As you spend time creating
remotes, we think you will nd this functionality easy to use, exible and powerful.

that will have only two states, e.g. vacation mode. The Second Counter is useful for keeping
lights on for specic periods of time. The Second Counter is a down counter only.
Static ags are stored in ash memory, so if power fails, when the Cortexa comes back up it
will continue where it left off. Second Counters are not stored in ash, so when the Cortexa
comes backup, the current value will be set to 0. Once the down counter reaches 0, the
counter will stop.

All sub-systems that are not congured into the system should be set to Disabled. Also
ensure that all required parameters are entered. For example, HAI security requires the
master security code to be entered. Some sub-systems may be congured to different baud

The Ascii data sub-system is used where there is a need to have a RS-232 connection to a
device, but there is no sub-system interface built into the Cortexa. An example could be a
CE device such as a receiver or DVD player. In this case a physical RS-232 connection is
made between the device and the Cortexa and the Com port is congured appropriately.
The sending of the ascii data is then set up using events.
The GC-IRE/L sub-system is used to congure the Global Cache to be able to detect incoming
IR (a button press on a remote control. The conguration parameters are shown above with
the Com port set to Network and the IP address and port (4999) numbers of the Global
Cache devices being used entered in their respective boxes.
The application of this using the Global Cache controller is to enable buttons on IR remote
controls to run Cortexa events. For example, an unused button may be “mapped” to the
“Goodnight” event, shutting the house down for the evening from one button press. See the
41
Event Management section for more details on how to set up the IR trigger.
This functionality is achieved using a standard Global Cache network controller, with the
addition of two other pieces of hardware; the GC-IRE and the GC-RG1, shown above. The
IRE attaches to the Global Cache serial port and the RG1 plugs into the IRE. The RG1 is
an IR receiver and is used to receive the IR signal from the remote control which is then sent
through the Global Cache serial port to the Cortexa.
ConneCting to deviCes over ethernet
While most sub-systems are connected to the Cortexa Home Controller using RS-232
connections, the Cortexa software also supports the connection of devices over Ethernet.
Two such devices able to take advange of this are the Elk security system, and the Global
Cache network controller.
This effectively enables the RS-232 port on the device to be utilized as an additional serial
port. This may be particularly useful in situations where the sub-system to be connected is

located close to the Global Cache device, e.g. audio distribution controller, but far from the
Cortexa controller.
The screen shot above shows Whole House Audio sub-system congured in this way. The
physical connection is therefore between the RS-232 port on the audio controller to the
RS-232 port of the Global Cache device. Above you can see how this is congured in
Sub-system Setup conguration page. The Com port is set to Network, and the IP address
and port number (4999) of the Global Cache to which the audio controller is connected are
entered. Some Global Cache devices have two serial ports, in which case the second port
number would be set here to be 5000.

wide area network
Media Access Control address: this is a hardware address that uniquely identies each
node of a network
With the MAC address eld, you can assign the Cortexa 7202 a MAC address, which is a
12-digit code assigned to a unique piece of hardware for identication. Some ISPs require
47
that you register the MAC address of your network adapter that is connected to your cable
or DSL modem.
Therefore, in order to connect the Cortexa 7202 to your cable or DSL modem instead of
the PC (network card or adapter), you must change the Cortexa 7202 MAC to duplicate
(or clone) your network card/adapter. You can nd your adapter’s MAC address by doing
the following:
• If you are running Windows 95,98 or Millennium: Go to the Start, Run, type in
command, and press Enter. At the DOS prompt type winipcfg
• If you are running Windows NT 4.0, 2000 or XP: Go to Start, Run, type in
command, and press Enter. At the DOS prompt type ipcong /all.
The Physical Address with 12 digits is your adapter’s MAC address. Enter those 12 digits
into the MAC Address elds, and click Apply. This “clones” your network adapter’s MAC
address to the Cortexa 7202, and prevents you from having to call your ISP to change the
registered MAC address to the adapter’s MAC address.

The Cortexa can be congured as a DHCP Server from the DHCP Screen. The Dynamic
Host Conguration Protocol (DHCP) – A protocol that lets network administrators centrally
manage and automate the assignment of Internet Protocol (IP) addresses in an organization’s
network using the Internet’s set of protocol (TCP/IP). Each machine that connects to the
Internet needs a unique IP address.
51
When an organization sets up its computer users with a connection, the IP address must be
entered manually at each computer and, if computers move to another location in another
part of the network, a new IP address must be entered. DHCP lets a network administrator
supervise and distribute IP addresses from a central point and automatically sends a new IP
address when a computer is plugged into a different place in the network.

If you use an NT 4 domain, or have pre-Windows 2000 clients that need to access an Active
Directory domain, you will need to ll in your WINS server IP addresses in these boxes. If
you only have one WINS server, leave the second box blank.
Default and Maximum Lease Time
The default lease time is the length of the DHCP lease on any clients that do not request a
specic expiration time on their DHCP lease. The default is 7200 seconds, or two hours. For
the vast majority of network environments, this is too low. We recommend setting this to one
week; 604,800 seconds.
The maximum lease time must be more than the default lease time. Most networks will not

sTaTiC dhCp mappiNg
Static DHCP mappings can be used to assign the same IP address every time to a particular
host. This can be helpful if you dene access rules on the rewall or on other hosts on your
LAN based on IP address, but still want to use DHCP. Alternatively, you can keep the IP
address box blank to assign an IP out of the available range, when you are using the “Deny
unknown clients” option.
Click the + icon at the bottom of the DHCP conguration page to add a static DHCP
mapping.

In the MAC address box, ll in the system’s MAC address in the format xx:xx:xx:xx:xx:xx.
For Windows NT/2000/XP clients, you can get determine the MAC address by opening up
a command prompt and typing ‘ipcong’. For Windows 95/98/ME clients, go to Start, Run,
winipcfg. For Unix clients, use ifcong. In the IP address box, ll in the IP address you want
to be assigned to the client, or leave it blank to automatically assign one from the available
DHCP range. If you enter a static IP address, it must not be within the range of the DHCP
server.
It is recommended you ll in a description in the Description box to remind you what this
entry is for, though this is optional.
Click Save when you are nished and the mapping will be added.

dns override
DNS – The Domain Name System (DNS) is the method by which Internet domain names are
located and translated into Internet Protocol (IP) addresses. A domain name is a meaningful
and easy-to-remember name for an Internet Address.
If there are certain DNS host names you want to override for your internal DNS clients, add
them under DNS overrides on this page. For example, if you want www.yourcompany.com to
point to a different site internally than it does from the Internet, enter an override for www.
yourcompany.com with the appropriate IP address.
This can also be used as a rudimentary, and easy to bypass, lter on web sites LAN clients
can visit by assigning the undesired host name to an invalid IP address. For example, to
block www.example.com, put in an override to redirect it to an invalid IP address, such as
1.2.3.4. Note that using a different DNS server or editing the hosts le on the client machine
54
gets around this restriction, but doing this is sufcient to block the site for the vast majority
of users.
If your Cortexa acts as the DHCP server for your LAN, and you need name resolution
between hosts on the LAN, check the “Register DHCP leases in DNS forwarder” box. This will
append the default domain in Interfaces: General Setup. For example, if your PC name is
my-pc and your default domain is example.com, it will register my-pc.example.com with the
IP address assigned from DHCP, so the other hosts on your LAN can locate your machine by
that name.

dynamiC dns
This screen allows you to congure Dynamic DNS. Dynamic DNS gives you the ability to nd
your Network over the Internet even though you do not have a static IP.

CoNfiguriNg The dyNamiC dNs ClieNT
To start, rst check the “Enable Dynamic DNS client” box at the top of the page.
In the “Service type” drop down box, select the service you are using.
Some services support MX DNS records on dynamic DNS sub-domains. This helps ensure you
can get email to your host name. If your service supports this (dyndns.org is one that does,
others do as well), ll in your mail server’s host name in that eld. If you do not need an MX
record, or if your provider does not support them, just leave the eld blank.
Wildcards - If you want to enable wildcard on your dynamic DNS host name, check this
box. This means all host names not specically congured are redirected to your dynamic
DNS name. So if your dynamic DNS is example.homeip.net, and you enable wildcards,
www.example.homeip.net, mail.example.homeip.net, anything.example.homeip.net, etc. (i.e.
56
*.example.homeip.net) will all resolve to example.homeip.net.
The next two boxes are for your username and password. Enter your account information
from the Dynamic DNS provider.
Click Save. Your dynamic DNS host name should immediately be updated with your WAN IP
address. To verify this, ping your dynamic DNS host name. It should resolve to the IP address
of the WAN interface of your Cortexa. If not, check Diagnostics: System Logs for information
on why it failed.
Proxy arP
Proxy ARP means that a particular system, such as a rewall, will respond to ARP requests
for hosts other than itself. This can be used to make a rewall mostly disappear from the
systems on a network.
For example, if you had a /28 subnet from your ISP that is routed through the Cortexa
router, your router appears at the IP of x.x.x.97 with a network address of x.x.x.96 and
a broadcast address of x.x.x.111. This leaves a usable chunk of 14 addresses for your
hosts.
Version 2.2
Page 57
Cortexa 7202 ConfiGuration utility
Continued
If you wanted to rewall these hosts from the Internet without using Proxy ARP, you would
need to subnet your addresses and therefore lose two more addresses for the new network
and broadcast, plus half of your remaining IP’s would be in the non-rewalled half.
Another method would be to have the rewall do port forwarding between all of the
addresses to non-routed IP’s (192.168.x.x) for your servers. Done properly, this would be
work. It isn’t as transparent and may break some protocols like active FTP.
By using Proxy ARP, you can set up your systems in a DMZ to separate them from your client
systems. This is also the least invasive method to set up, since you can keep the same IP’s on
all of the servers as you had when things were not rewalled.
57
snmP
You can enable SNMP on your LAN interface on this screen. This is useful if you have a
network management or monitoring system that takes advantage of it.
The System location and System contact boxes can be left blank, but can assist you in
determining which device you are monitoring if you have several monitored hosts.
The Community is generally set to public, but if you are concerned about security, you should
set this to something difcult to guess, containing numbers and letters. This community name
is still passed over the network in clear text, so it could be intercepted, though the most
anyone could get with that community name is information on the setup and utilization of
your rewall. In most environments, this is likely to be of little to no concern, but is something
to keep in mind.

• Port: The ports that the source is allowed to connect to
• Description: An easy way to identify the rule
Rules may be prioritized with the arrows, and are evaluated on a rst-match basis (i.e. the
action of the rst rule to match a packet will be executed). This means that if you use block
rules, you will have to pay careful attention to the rule order. Everything that is not explicitly
passed is blocked by default.

Interface
Interface is generally set to WAN in order to permit trafc coming from the Internet. You can
also select any optional interfaces here.
Optional interfaces might be useful on a DMZ interface to allow access from the DMZ to a
port on a host on your LAN. For example, if you want to use a LAN DNS server, you could
put an Inbound NAT rule in on the DMZ interface opening UDP port 72 to your DNS server’s
LAN IP address, and use Cortexa’s DMZ interface IP address as your DNS server on DMZ
hosts. There is no real advantage doing this versus putting in a rewall rule to permit this
trafc, and using the LAN IP address of the DNS server.
External address
External address is set to the WAN interface IP address. If you have multiple public IP’s, you
can use other addresses here that you have previously dened on the Server NAT tab.
61
Protocol
Choose which IP protocol the service you are using requires, TCP, UDP or TCP and UDP.
External port range
Either select the desired protocol from the drop down box, or type in the port range in the
text boxes. You can leave the “to” eld empty if you only want to map a single port.
Forward IP
This is the internal IP address of the machine to which you are mapping the ports. In the
given example, the LAN IP address of the web server is 192.168.10.4. This can also be a
host on an optional network, and ideally it will be to a host on a DMZ. You should avoid
opening ports to your LAN if possible.
Local port
This is the port on the Forward IP dened above to which we want to translate the connection.
In this case it is the same as the external port, but it doesn’t have to be.
Description
Optional, however we strongly recommend putting in a description so you remember the
purpose of this entry, and to make your rules easier to read and comprehend.

likely to be incorrect or problematic.
Click Save, then Apply Changes. You will then see the result, similar to the following.

62
Forwards, you need to dene the address in Server Forwards rst.
1:1 forWard
1:1 Forward maps an internal IP to external IP, generally mapping a public IP address to
a private IP address and vice versa. When you assign a 1:1 Forward mapping, any trafc
coming from that host to the Internet will be NAT’ed to the dened external IP, and any
trafc coming into the external IP will be NAT’ed and passed to the internal IP if rewall
rules permit. (by default, the rewall rules do not allow any inbound trafc to 1:1 Forward
mappings). You can also map entire subnets with one entry.

aliases
Aliases act as placeholders for real IP addresses and can be used to minimize the number of
changes that have to be made if a host or network address changes. You can enter the name
of an alias instead of an IP address in all address elds that have a blue background. The
alias will be resolved to its current address according to the list below. If an alias cannot be
resolved, e.g. because it has been deleted, the corresponding element will be considered
invalid and skipped.
statiC route
Paths through the network must be found and made available to the router so it knows the

n vPn (virtual Private network)
Virtual Private Networking (VPN) is a security measure that basically creates a secure
connection between two remote locations. The connection is very specic as far as its settings
are concerned; and creates the security. The VPN screen allows you to congure your VPN
setting to make your network more secure.
iPseC
This is used if you decide to build an IPSEC tunnel between your rewall and some other
network. The most common uses we see are connecting home networks to the ofce, or
66
setting up private WANs.
There is only one section of the Cortexa interface that you need to use to do this.
Now we need to add a VPN connection, to do this click on the icon.
The rst area is the one you use to establish what network ranges will use this IPSEC tunnel.
Version 2.2
Page 67
Cortexa 7202 ConfiGuration utility

67
This is the rst set of elds that we need to concentrate on. Later, when testing your tunnel,
you can actually fail to establish level 2 connection if this data is incorrect. We will note what
to pay particular attention to as we go along.
Mode: This cannot be changed.
1.
Disabled: This is an “on / off” button if you need to disable the tunnel for whatever
2.
reason. Simply select the edit or from the main VPN: IPsec window and click this
checkbox element, then select Apply at the bottom of the page. When you need
the tunnel again, reverse the process.
Interface: This is how you determine which part of your network will be the
3.
termination point end point for the VPN Tunnel. If you are connecting to a remote
server, then WAN is your option.
Local subnet. This is where you can set which parts, hosts, or the entire LAN, can
4.
be accessed from the other side of the VPN tunnel. The easiest thing to do is to set
the LAN subnet as the option; this means your entire LAN will be accessible from
the remote network. IMPORTANT: The other end of the tunnel has this same eld.
Make sure the other end is set exactly as you set this end. For example, if you
selected “Single host” in this section and entered the IP address of that host, the
other person would set that host in their “Remote Subnet” eld.
Version 2.2

Cortexa 7202 ConfiGuration utility

Remote Subnet. This is more than just labeling which host(s) you want to access on
5.
the other network. As mentioned in item 4 it is paramount that you set this exactly
like the “local subnet” section. If not, level 2 of the VPN connection will fail and
trafc will not pass from one VPN segment to the other.
Description: We strongly encourage some documentation here.
6.
Now that the basics for the routing have been established. We can now move to phase 1 of
the VPN authentication process.
68
Here, and even in phase 2, it is vital to ensure both VPN servers have EXACTLY the same
settings for all of these elds.
Negotiation mode: This is the type of authentication security that will be used.
1.
Unless you are extremely concerned about security, leave this as aggressive. It is
signicantly faster and will ensure that your VPN tunnel will rebuild itself quickly
and probably won’t timeout an application if the tunnel was down when the
resource on the other end was requested.
My Identier: This is the key to probably 90% of problems where the VPN tunnel
2.
is not established. Very simply, set your identier to something that isn’t going to
change. So if you leave it as My IP address, then make sure that IP is static and
persistent. If you use a DHCP assigned address then we suggest using domain name
instead. This is because the domain name can be completely your own, even if you
do not own the domain name.
Version 2.2
Page 69
Cortexa 7202 ConfiGuration utility
Continued
Encryption Algorithm: 3DES is the de facto standard if you are connecting to
3.
another Cortexa, or a system that will support it, change this to Blowsh. It is more
secure and about twice as fast! If you are trying to connect to a VPN device that
only supports DES then you will need to downgrade and hope no one decrypts
your key exchange. MAKE SURE BOTH VPN DEVICES ARE USING THE SAME
ENCRYPTION ALGORITHM.
Hash Algorithm: this is the hash used for checksum. MD5 is a good choice, SHA1
4.
is another algorithm, but not everything supports it. Again make sure you are using
the same setting as the other end of the tunnel.
DH Key Group: Most systems will support at least up to 1024 bit. This is what we
5.
recommend using.
Lifetime: This eld is more important than it appears. This lifetime, as opposed to
6.
the one in phase 2, is how long your end will wait for phase 1 to be completed. We
suggest using 28,800 in this eld.
69
Pre-Shared Key: This key must be exactly the same on both VPN routers. It is case
7.
sensitive, and it does support special characters. We suggest using both.
Phase 2 is what builds the actual tunnel, sets the protocol to use, and sets the length of time
to keep the tunnel up when there is no trafc on it.
Version 2.2
Page 70
Cortexa 7202 ConfiGuration utility
Continued
Protocol: ESP is the de facto VPN transport protocol. We suggest leaving this as is.
1.
Note: The system should auto-generate a rewall rule for you to allow ESP or AH
to the endpoint of the VPN. We will check this later. If it does not, you will need to
make a rewall rule allowing ESP (or AH if you changed this) trafc to the interface
you established as your end point of the tunnel. We will outline that later.
Encryption algorithms: As before in phase 1, make sure you are setting the
2.
algorithm exactly as it is set on the other VPN server. You can use several, and
when you do so everything you select is available for use. We recommend keeping
things simple so only check the one you are going to use.
Hash algorithms: Just as in phase 1, make sure your selected hash matches
3.
on both ends. And as in step 2, don’t add things you don’t need. SHA1 is the
suggestion if you can, but MD5 is always a good alternative.
PFS key group: this works exactly like it does in phase 1. We suggest using 1024
4.
bit, the default is off.
70
Lifetime: This is the lifetime the negotiated keys will be valid for. Do not set this to
5.
too high. We suggest one day, 86,400. A value larger than this will be less secure.
PPtP
PPTP Point to Point Tunneling Protocol – A protocol that allows the Point to Point Protocol
(PPP) to be tunneled through an IP network. PPTP does not specify any changes to the PPP
protocol, but rather describes a “tunneling service” for carrying PPP (a tunneling service
is any network service enabled by tunneling protocols such as PP2P, L2F, L2TP , and IPSEC
tunnel mode). One example of a tunneling service is secure access from a remote small
ofce network to a headquarters corporate intranet via a Virtual Private Network (VPN)
that traverses the Internet. However, tunneling services are not restricted to corporate
environments and may also be used for personal (i.e., non-business) applications.
If you have your own internal PPTP server, you may redirect the PPTP request to your
internal PPTP server.

have tested the Library and Player functionality with many hardware devices and software
applications and recommend using Windows Media Player 11 unless you have a preference
for an alternative platform.
The library that you are sharing from must be congured to share les with the Cortexa.
This is done within the application, e.g. WMP11. Multiple libraries on the same network
may be shared.
Having congured your music library to share, the Cortexa Library and Player functionality

This appendix consists of frequently asked questions, and may provide possible solutions to
problems regarding the installation and operation of the Cortexa.
If you need further support, please contact us at [email protected].
I need to set a static IP address on a PC
The Cortexa, by default, assigns an IP address range of 192.168.10.100 to 192.168.10.150
using the DHCP server in the Cortexa. To set a static IP address, you can only use the ranges
192.168.10.2 to 192.168.10.99 and 192.168.10.151 to 192.168.10.254. Each PC or
network device that uses TCP/IP must have a unique address to identify itself in a network.
If the IP address is not unique to a network, Windows will generate an IP conict error
message. You can assign a static IP address to a PC by performing the following steps:
For Windows 95, 98, and Me:
A. Click Start, Settings, and Control Panel. Double-click Network.
B. In The following network components are installed box, select the TCP/IP-
>associated with your Ethernet adapter. If you only have one Ethernet adapter
installed, you will only see one TCP/IP line with no association to an Ethernet
adapter. Highlight it and click the Properties button.
C. In the TCP/IP properties window, select the IP address tab, and select Specify an
IP address. Enter a unique IP address that is not used by any other computer on
the network connected to the Router. You can only use an IP address in the ranges
192.168.10.2 to 192.168.10.99 and 192.168.10.151 to 192.168.10.254. Make
sure that each IP address is unique for each PC or network device.
D. Click the Gateway tab, and in the New Gateway prompt, enter 192.168.10.1,
which is the Cortexa’s default IP address. Click the Add button to accept the entry.
E. Click the DNS tab, and make sure the DNS Enabled option is selected. Enter the
Host and Domain names (e.g., John for Host and home for Domain). Enter the DNS
entry 192.168.10.1 (Cortexa’s default IP address).
F. Click the OK button in the TCP/IP properties window, and click Close or the OK
button for the Network window.
G. Restart the computer when asked.

I am a PPPoE user, and I need to remove the proxy settings or the dial-up popup
window
If you have proxy settings, you need to disable these on your computer. Because the
Cortexa is the gateway for the Internet connection, the computer does not need any proxy
settings to gain access. Please follow these directions to verify that you do not have any
proxy settings and that the browser you use is set to connect directly to the LAN.
For Microsoft Internet Explorer 5.0 or higher:
A. Click Start, Settings, and Control Panel. Double-click Internet Options.
B. Click the Connections tab.
C. Click the LAN settings button and remove anything that is checked.
D. Click the OK button to go back to the previous screen.
E. Click the option Never dial a connection. This will remove any dial-up pop-ups for
PPPoE users.
For Netscape 4.7 or higher:
A. Start Netscape Navigator, and click Edit, Preferences, Advanced, and Proxies.
B. Make sure you have Direct connection to the Internet selected on this screen.
C. Close all the windows to nish.
I can’t access my email, web, or VPN, or I am getting corrupted data from the Internet
The Maximum Transmission Unit (MTU) setting may need to be adjusted. By default,
the MTU is set at 1500. Most DSL users should use MTU 1492. If you are having some
difculties, perform the following steps:
A. To connect to the Cortexa, go to the Web-based Utility, as shown in “Section 6.2”.
B. Click the Advanced => Wan tab.
C. Look for the MTU option, and in the Size eld, enter 1492.

When I enter a URL or IP address, I get a time-out error or am prompted to retry
A. Check if other PCs work. If they do, ensure that your workstation’s IP settings
are correct (IP Address, Subnet Mask, Default Gateway, and DNS). Restart the
computer that is having a problem.
B. If the PCs are congured correctly, but still not working, check the Cortexa. Verify
that it is connected and ON. (If you cannot connect to it, check the LAN and power
connections.)
C. If the Cortexa is congured correctly, check your Internet connection (DSL/cable
modem, etc.) to see if it is working correctly. You can remove the Cortexa to verify
a direct connection.
D. Manually congure the TCP/IP with a DNS address provided by your ISP.
E. Make sure that your browser is set to connect directly and that any dial-
up is disabled. For Internet Explorer, click Tools, Internet Options, and then
the Connection tab. Make sure that Internet Explorer is set to Never dial a
connection. For Netscape Navigator, click Edit, Preferences, Advanced, and
Proxy. Make sure that Netscape Navigator is set to Direct connection to the
Internet.
What is the maximum number of IP addresses that the Router will support?
Cortexa will support up to 272 IP addresses.
Version 2.2

Where is the Cortexa installed on the network?
In a typical environment, the Cortexa is installed between the cable/DSL modem and the
LAN. Plug the Cortexa into the cable/DSL modem’s Ethernet port.
Does the Cortexa support IPX or AppleTalk?
No. TCP/IP is the only protocol standard for the Internet and has become the global
standard for communications. IPX, a NetWare communications protocol used only to route
messages from one node to another, and AppleTalk, a communications protocol used
on Apple and Macintosh networks, can be used for LAN to LAN connections, but those
protocols cannot connect from WAN to LAN.
Does the Cortexa’s WAN connection support 100 Mbps Ethernet?
Yes, it does support 100 Mbps over its auto-sensing 10/100 port.
What is Network Address Translation and what is it used for?
Network Address Translation (NAT) translates multiple IP addresses on the private LAN
to one public address that is sent out to the Internet. This adds a level of security since
the address of a PC connected to the private LAN is never transmitted on the Internet.
Furthermore, NAT allows the Router to be used with Internet accounts such as DSL or cable
modems, when only one TCP/IP address is provided by the ISP. The user may have many
private addresses behind this single address provided by the ISP.
I am not able to access Cortexa’s Web-based Utility. What can I do?
You may have to remove the proxy settings on your Internet browser, e.g., Netscape
Navigator or Internet Explorer. Or remove the dial-up settings on your browser. Check with
your browser documentation, and make sure that your browser is set to connect directly
and that any dial-up is disabled. Make sure that your browser is set to connect directly
Version 2.2
Page 84
appendix a

Continued
and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and
then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection.
For Netscape Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that
Netscape Navigator is set to Direct connection to the Internet.
Does the Cortexa pass PPTP packets or actively route PPTP sessions?
The Cortexa allows PPTP packets to pass through.
Does the Cortexa replace a modem? Is there a cable or DSL modem in the Cortexa?
No, the Cortexa must work in conjunction with a cable or DSL modem.
