WHAT YOU NEED
Computer: Pentium 4 or better
Monitor: Capable of MINIMUM display resolution 1024 x 768
Operating System: Microsoft Windows XP, XP Professional, Vista
Local Area Network Connection
Internet Browser: Internet Explorer, Mozilla FireFox
The installation and setup for the IntelliSwitch Web Server (IWS) must be performed by a person with a
working knowledge of the internet, local area networks and computers, such as a LAN Administrator.
CONNECTING WEB SERVER
CONCOA strongly suggests that this device be placed behind a firewall. Is it not suitable for public
internet access.
The IWS is designed to communicate via a local area network connection. Power to the IntelliSwitch
should be OFF. Connect the IWS to the network via an RJ-45 network cable. The RJ-45 connection
on the IntelliSwitch is located on the bottom of the IntelliSwitch. It may be necessary to remove the
protective cover to access the RJ-45 connection on the IntelliSwitch.
The IWS is configured with the following default network settings:
IP Address: 192.168.0.83
Default Gateway: 192.168.0.100
To change the network settings connect to the IWS use the following procedure:
Using either Internet Explorer or Firefox and the newly assigned IP address (192.168.0.83), enter
the following in the address box at the top of the screen:
http://192.168.0.83/config/config.html.
Username: admin
Password: PASS
If connected properly, an image similar to the one in Figure 1 below should appear on your screen.

http://xxx.xxx.x.xxx/intelliswitch/status.html.
If connected properly, an image similar to the one in Figure 4 below should appear on your screen.
ADDING IWS TO DESKTOP
For convenience the IWS should be added to your favorites and/or your desk top. To do this, reduce the
IWS image using the “Restore Down” icon in the upper right corner of the screen so that it only occupies
a portion of your desktop. Next, open up favorites and find your new entry for the IWS and drag it over
to the desk top. You may wish to rename the icon so that it has a name that is easily recognized for the
device being used. The IWS is now ready to use. Refer to the section “USING THE WEB SERVER” to
learn what functions it has and how to use it.
Figure 4
USING THE WEB SERVER
FEATURES:
The IWS has a number of useful features. The STATUS screen is what appears when the IWS is first
accessed. This screen provides the ability to monitor a number of parameters as well as providing an
“event log” that allows viewing of IntelliSwitch activity. Clicking on the EDIT button will bring the user
to the EDIT screen. Here it is possible to change various parameters within the IntelliSwitch. Also on the
EDIT screen are two buttons marked EMAIL1 & EMAIL2. Clicking on one of these buttons will bring

Units of Measure
Choices are PSI, BAR and MPA. Pressures will be displayed in
the units shown in this area.
5
GAS Type
Displays the gas type the IntelliSwitch is controlling. This is set
by the user from the EDIT screen.
6
Reserve Supply Status
If the product is equipped with a Reserve Gas Source the status
of that source will be displayed here. Green In-Use indicates
that the IntelliSwitch is using this source. A Red Fault indicates
that the reserve supply is low on gas and needs to be replaced.
It is possible to have the Reserve in-use and have a fault. This
would occur if both the left and right inlets are also in replace.
7
Switchover Pressure
This is a preset pressure in the IntelliSwitch used to determine
when an inlet can no longer provide enough gas pressure to the
delivery regulator. This value can be changed in the EDIT
screen.
8
Hysteresis
This is a preset pressure value that is used to prevent the
IntelliSwitch from “dithering” at the switchover point.
9
Look Back
This is a preset time in minutes used for liquid cylinders to
determine when to look back at an inlet pressure to determine if
pressure has been restored above the switchover point. The
IntelliSwitch will look back at an inlet after the look back time has
expired to see if its pressure has built back up above the
switchover point. If it has, then the IntelliSwitch will switch back
to that side to try to use more of the gas.
10
Switch back
A preset time in minutes used for liquid cylinders in conjunction
with the look back time. If the look back feature is invoked and
after time out has determine that it can switch back to a side
whose pressure has built back, a switch back timer will start. If
the inlet pressure on the same side drops again before the
switchback time has expired the IntelliSwitch determines that
that side is truly empty and will alarm and switch to the other
inlet.
11
Delivery Pressure Tolerance
This is the variation in delivery regulator pressure that is allowed
before the IntelliSwitch switches regulators and alarms. The
value is +/- the pressure shown.
12
Delivery Regulator Alarm
Delay
This is the amount of time, in seconds, that the IntelliSwitch will
wait before switching delivery regulators or alarming. This
prevents false switching and alarming if the delivery regulator
pressure should increase or decrease from its nominal value
beyond the delivery regulator tolerance for a very brief time.
