1. Overview
1.1. Introduction
The AquaMetrix 2300 Controller is the first multi-input controller that brings web-based operation down to
a price that can be afforded by just about any facility. Its combination of features—remote control, data
logging, email alerts and seven inputs—are unparalleled in the water monitoring market. Its Setup Wizards
make set-up and operation a snap.
The Quick Start Guide is a companion manual that is designed to get the user up and running quickly. If
you don’t have this guide you can download it from our website: http://wateranalytics.net/products/2300.
This manual is also available on this web page.
This manual attempts to cover the many facets of setup and operation in detail.
The standard configuration accepts inputs for four 4-20mA (analog) sensors and three frequency output
(aka digital) sensors—mainly flow sensors such as paddlewheels and magmeters. Outputs include four
relays and virtually unlimited email/text notifications. The 2300 Controller provides remote viewing
capability and configuring with password from any connected web browser. It also provides data logging
with downloading or emailing of log files in CSV format. There is also one available slot for an optional
card, which can expand digital inputs or relays outputs, or add analog outputs.
We are constantly making improvements to the user interface so please check in to make sure you have the
latest version.

WARNING: If this equipment is used in a manner not specified by the manufacturer as per the Users
Manual and this Quick Start Guide, the protection provided by the equipment may be impaired.
2.1. Panel Mounting
Mount the 2300 Controller through the front panel, with the gasket on the outside of the mounting panel.
Hook the sliding mounting blocks on each side of the back of the 2300 Controller enclosure and tighten
the set-screws against the mounting panel with a torque of 4 in-lb, as shown in Figure 2-1.
Figure 2-1 - Mounting hardware attached to panel with 4 in-lb of torque
2300 Controller User’s Manual, Rev. 5 Page 6
2.2. Power, Probe, and Network Cabling
A picture of the rear of the 2300 is shown below in Figure 2-2. We recommend removing the Molex
connectors and connecting wires to them and then attaching the connectors to the unit.
Connect the:
• Power cord
• CAT-5 Ethernet cable—to be used later as described in Section 5.
• Probe wires: Two-wire 4-20 mA cables connect to the analog connector. Pulse inputs connect to
the digital inputs.
Probe wiring depends on the type and manufacturer of the probe, and instructions can be found with each
probe. We show examples of the different wiring diagrams in Figure 3 that may be called for by your
analog (4-20 mA) probes, but please look up your individual probe directions. Connections for flow meters,
which output a pulse frequency, such as paddle wheels or magmeters, use the pulse input connector (“dig
in 1” et al).
Note: The 2300 controller comes with a microSD card that is used for firmware updates. If you purchase a
second card it is important that the card has a speed rating of at least 10.

Figure 2-3 shows the wiring for the three most common analog sensors plus a current sinking flow meter.
Please refer to the sensor manufacturer’s instructions to be sure you wire your sensor correctly. This is
especially important for 3-wire probes, which differ in the power connection of the 4-20 mA wiring.

2.3. Relay Wiring
The 2300 controller has 4 relays that can be expanded to 10 with the addition of a second card. The relays
are capable of handling 120 V @ 10 A or 240 V @ 5 A. They can also be part of a 24 VDC circuit. Unlike the
Shark-120 the relays are not powered. To power a relay and the device to be controlled (e.g. a pump or a
solenoid) wire the relay circuit as shown.
Figure 2-4 - Electrical Connections for a circuit involving a relay, power source and device.
2.4. Powering Up the 2300
With the probes connected, power up the 2300. If the controller is operating properly, the green LED's on
the back panel indicate proper operation. (See Figure 2-2.) From top to bottom:
1. The top most LED is the Fault light it should be slowly blinking.
2. The middle LED is the System Operating light and it should be quickly blinking.
3. The bottom LED is the Power On light and it should be on and steady.
The Run screen should appear and display 4 panes. It will show the actual mA reading of the four analog
probes (see Figure 3-2). Dashes (----) indicate that a probe is either not connected or it is out of range. Note
that the preconfigured software only shows the actual current being read by the 2300. In order to have
probe outputs expressed in the appropriate units (e.g. pH, mV, µS/cm, etc.) you need to carry out set-up
over a network using a web browser. See Section 4.1 or 4.3 of this guide for network setup, and Section 5
for configuring the 2300 over the network. The main purpose of this initial screen showing the raw current
outputs of the connected probes is simply to reassure you that that controller is running properly.
2.5. Configuring the 2300 for Network Operation
The default setup for the 2300 includes Dynamic Host Control Protocol (DHCP) for automatically assigning
an IP address to a unit. This IP address is the key piece of information that allows users to locate and log
into any 2300 on a local or wide area network.

Once the controller is connected a Local Area Network (LAN) the router will assign the 2300 its IP address.
To find out what that IP is:
1. Click on the Menu button.
2. Click on the top-most menu item, View System Info.
3. The IP address is listed on the second line. See Figure 2-5.
Figure 2-5 - The IP address of the 2300 assigned by the router is listed on the second line.
Section 4.3 goes into network connectivity in greater depth.
3. Operating the 2300 from the Front Panel
3.1. Front Panel Display
The 2300 front panel display shows a series of RUN screens and MENU screens. It does not have the full
functionality of the web interface and is meant to be a local display and secondary user interface.
There are eight navigation buttons below the screen: four arrow buttons and the following:
• The RUN button brings up the quad screen from anywhere
• The MENU button brings up the front panel menu
• The BACK button returns the user to the previous screen.
2300 Controller User’s Manual, Rev. 5 Page 10
Figure 3-1 - The Run display on the left reports 4 process values at a time. If there are more than 4 pressing ! reveals
the hidden values. The identical image appears on the web browser. The Detail screen on the right shows the detailed
status of the Tank pH condition, including process value and alarm or relay.
• The Run screen includes a summary screen showing the status and values of 4 probes at one time.
If more than 4 probes are enabled in the controller, the ! and "buttons will allow you to see
additional probes.
• Each quadrant in the Run screen shows a probe label, current value with units, trend arrows for
the reading, and a status light for the controller outputs. The status light is:
o Green for normal operation
o Yellow for an activated relay
o Red for an activated alarm
• Pressing #brings you to the Detail status screen for one sensor. As Figure 3-1 shows, this screen
lists the action outputs for this probe, including the action description and set-point value, and the
last calibration date. The actions are color coded, with green for normal operation, red for alarm
condition, and yellow for an activated relay.
• The !and " buttons cycle through screens of individual probes. Pressing the $ button brings
back the Run screen.
• When a probe activates an alarm the front panel display automatically switches to a flashing
detailed Detail screen. To restore the display to the Run screen press the Run button.
• Pressing the Enter button will bring up a Meter Action screen, allowing the user to acknowledge
an alarm, if active, or setting relay trip points.
• Press the Run button to return to the Run screen.
3.2. Optional Pre-configured Operation
If specified in the order the 2300 controller can come software-preconfigured for six probes, allowing the
user to wire up probes and start operation without configuring the unit over the web interface. This

convenience is simply meant to allow you to connect probes and verify that they produce signals. It is not
meant to replace the web-based set-up.
Analog 1 corresponds to the analog 1 input on the back of the unit. The first 4 software channels are
shown on the RUN quad screen. If you have more than 4 sensors connected, press the down arrow to see
channels 3 through 6. Channels 5 and 6 are pre-configured as flows using the pulse inputs 1 and 2 (see
Figure 2-2).

The RUN screen showing four analog probe inputs. On the left is a display showing that no probes have been connected. On
the right, four analog probes have been connected.
Use the right arrow on a quad screen to see Detail screens for each channel, addressable by the up or down
arrows. Pressing ENTER on a detailed screen brings up a configuration screen for that channel. Examples
of each are shown below in Figure 5. Press BACK or RUN to move up a level or two in the front display.
Figure 3-3 - The channel Detail screen and Configure screen for Channel 1
2300 Controller User’s Manual, Rev. 5 Page 12
The Detail screen lists alarm and relay set points, last calibration date, and will flash when the channel is in
alarm mode. The configure screen allows resetting of the alarm and relay set points, alarm
acknowledgement, and zeroing of the totalizer and dispenser functions and other channel-specific
functions.
3.3. Front Panel Menu
The front panel menu is limited to a select group of functions. The outline of this menu structure is listed in
Table 1.
These front panel menu items ensure that the unit may be connected to the web interface to allow the
complete configuration that you will need to do. When not connected to the web (or computer), the unit
still operates and all non-web-based features are still fully functional.

The front panel menu choices are limited as the 2300 is designed to be configured and operated over a
network via a web browser. However, there are several key functions available to the user on the front
panel. These include calibration and setting up the network. The main menu is shown in Figure 3-4.
2300 Controller User’s Manual, Rev. 5 Page 13
Figure 3-4 -Pressing the Menu button brings up the Main Menu screen.
Use the " or ! keys to highlight an item, and press the Enter key to select it. If there are more than 4
choices available, the bottom (or top) corner on the right will show a white triangle or notch. Some front
panel actions require a password to proceed. The default password is 48111.
The menu options are listed in outline form below in Table 1. You may calibrate your probes from the front
panel, but remember that full functionality of the unit is only available via the Ethernet cable from a
network, or browser on a computer, tablet, or phone. Customize your unit via a network to display proper
units, names of probes, and to configure alarms, relays, and notifications.

3.4. Calibrating Sensors from the Front Panel
Most routine operation of the 2300 is most conveniently done through the web interface. However, for
some installations—especially industrial ones—calibration may be more conveniently done through the
front panel. Note that front panel calibration only allows 2-point calibrations.
To calibrate from the front panel follow these instructions:
1. Press the Menu button.
2. Using the down arrow, select Calibrate/Disable Probe and click on Enter. A list of probes that
have been configured will appear.
3. Using the down button, to select the probe you want to calibrate, and click on Enter.
4. A new menu appears with two choices. Using the down button, select Perform Calibration and
click on Enter.
5. The next screen displays the existing calibration points for this probe, with the input current on the
left and the value readout to its right. Each point can be modified or left alone.
Figure 3-5 – Select Probe Calibration and then select 1 or 2 points at which to calibrate.
6. You may either enter calibration points—process value and associated current reading—manually
or automatically. In the latter case, you would insert a sensor into a calibration solution and click on
Use measured mA to take a measurement. To enter numbers manually you need to use the
numeric keypad. Remember that the display is not a touchscreen and you have to navigate toward the
number you want using the arrow buttons.
7. When you are satisfied that the calibration values, use the Down arrow to select Done. (Note: To
reach this button you must scroll down past the last button visible.) You will note that the front
panel and web interface update the date of calibration.
8. For the case of pulse output flow sensors, calibration requires changing the value of the K-factor,
which is done via the numeric keypad.
2300 Controller User’s Manual, Rev. 5 Page 15
Figure 3-6 - On the left is the numeric keypad for the manual entry of calibration numbers and the K-Factor.
3.5. Setting Relays from the Front Panel
Another operation that may be performed at the front panel is configuring relay set points. Except in the
rare case in which there is no access to a local area network, you will have already set up the relay trigger
points in the Probe Configuration Wizard. These instructions are for changing those values. You can follow
the sequence of screens in
1. First click on # to bring up a Detail screen. Unless the probe you wish to edit is the probe #1 you
will have to click on ! repeatedly until you see the screen for your desired probe.
2. Click on Enter. You will be presented with the Meter Actions screen. Click on Relay Set Points.
3. The next screen shows the relays that have been set. In Figure 3-7 they are “High pH” and “Low pH.”
Select the relay you want to modify and click on Enter.
4. The next screen shows the current relay set points. In the figure they are the set points for the high
pH relay—8.0 for the relay trip point and 7.8 for the reset point.
5. If Password access is turned on then the next screen asks for the front panel passcode. Enter the
code from the numeric display.
6. The next screen shows a second numeric display and asks you to enter the new trip point. Click on
Done when you finish entering the value. In the figure the new set point is 8.2.
7. The next screen (not shown) asks you to either Cancel or Proceed with your choice. Select and click
on Proceed.
8. The final screen shows the new set points. Click on Run to return to the default quad screen.

3.6. Saving and Restoring Your Configuration from the Front Panel
Once you have configured the 2300 with probe definitions, relay/alarm set pings and email and server set
ups, you can save these settings to the external microSD card via the front panel menu. This is a very
feature that is very helpful in case you unit loses its configuration.
1. Carefully insert a microSD card in the rear slot. (Be careful to insert the card into the slot and not in
the space above where the card will disappear into the box.)
2. Click on the Menu button. The Backup/Restore option is already selected. Click on Backup
Configuration.
3. The next screen will prompt you to Cancel or Proceed. Click on Proceed.
4. The next screen will display a message that the save was successful. If there is no microSD card you
will get the message, Backup Failed.
To restore the configuration:
1. insert a microSD card with the desired configuration file folder called BACKUP.
2. Click on the Menu button, scroll down to Save/Restore Configuration, and select Restore
Configuration.
3. The next screen will prompt you to insert the microSD card containing the Backup files and press
Enter to continue.
4. The IP address of the unit is stored on a Backup file. The next screen gives you the option of either
keeping the IP address as it currently exists or using the IP address from the Backup. Select and click
on your choice.
5. The next screen prompts you to either Cancel or Proceed. Select Proceed and click on Enter.
2300 Controller User’s Manual, Rev. 5 Page 17
6. The next screen will display a message that the save was successful. If there is no microSD card you
will get the message, Backup Failed.
The Restore utility only works with units having the same firmware build. Upgrades to firmware will not
change the configuration inside the 2300, so we suggest saving the configuration to a memory card after a
firmware upgrade.
4. Operating the 2300 from a Web Interface
Once you’ve become accustomed to working with the web-based interface you will undoubtedly find it
faster and easier to use it for nearly all operations.
4.1. Setting up an Ethernet Connection to a Network Router
Connecting the 2300 to an existing network with the Ethernet cable enables the 2300 to become a device
on the Local Area Network (LAN). This is the network that is visible to everyone inside your facility. All
devices that connect to the LAN have a unique address, called an IP (Internet Protocol) address. You may
manually assign the IP address with a number of your choosing or you can allow your router to
automatically assign the 2300 an IP address. Because the router may change that address this method is
called Dynamic Host Control Protocol (DHCHP).
4.2. Connecting to a 2300 within Your Local Area Network (LAN)
4.2.1. Assigning an IP address via DHCP
The easiest method for configuring the 2300 on a LAN is to use DHCP for assigning an IP address for the
2300. (See Section 2.5) You only need to set the Ethernet connection on your computer or smart device to
configure the 2300 via DHCP. The IP address is shown on the front panel during power up or can be seen
via the Main Menu under View System Info (Menu > View System Info).
The IP address will look something like 192.168.1.7. Save this address to access the 2300 from your Local
Area Network (LAN).
Changing IP addressing from Fixed IP to DHCP or vice versa is an operation that must be done on the front
panel. See Figure 4-1.
1. Click on the Menu button.
2. Scroll down with the ! key to the bottom-most menu item, Advanced Menu and click on it.
3. If password protection is enabled (Section 5.7.2), enter the numeric passcode.
4. Scroll down with the ! key to Network Setup and click on Enter.
5. The first menu item is Network Type. Click on Enter.
6. Select either Fixed or DHCP. In this section the choice is DHCP.
2300 Controller User’s Manual, Rev. 5 Page 18
Figure 4-1 - Sequence of menus for toggling between DHCP and Fixed determination of IP address.
4.2.2. Assigning a Fixed IP Address
The main reason for assigning a fixed IP address to a 2300 is to configure it on a wide area network.
However, even with DHCP, most routers very infrequently change IP addresses of devices.
To configure the 2300 with a fixed IP address first set the unit up for that mode. Follow the instructions in
the previous section. Request an IP address number and a port number from your IT person. If either one
conflicts with an existing device you will cause much pain and suffering.
4.2.3. Accessing the 2300 from a Wide Area Network
In order to access the 2300 from a Wide Area Network (WAN), i.e. outside your facility, you will need the
address of your router and the port number of the 2300. If you have only one 2300 to be accessed on a
WAN, you can use the Demilitarized Zone (DMZ) on your router so that you don’t need to set up a port
number.
1. You first need the IP address of your router, also called the External IP. This is NOT a number that
looks like other IP addresses, e.g. 192.168.1.20. To determine the address just open a browser and
enter the URL, www.WhatIsMyIP.com. The website will immediately show you the external IP. It will
look something like 24.148.220.199.
Entering the external IP address in a web browser should bring up the router’s web-based control
center. You can also connect to many routers by entering the IP address 192.168.1.1.
2. When you access your 2300 from outside your facility your browser needs to identify your LAN,
which it does through the external IP. Every item on your LAN has an IP address. Port forwarding
assigns a so-called port number to that LAN IP address.
3. Assigning a port number to the 2300 differs depending on your router. This manual won’t attempt
to cover every type of router configuration. Furthermore, assigning port numbers to IP addresses can
cause serious problems if not done correctly. That’s why we strongly suggest you give this job to an IT
specialist. With this warning in mind, here is a general guideline:
The port forwarding number can be any number not taken by another device. However we
recommend avoiding any number between 0 and 100 and, preferably, a 5-digit number. Let’s say
you choose 5000 for the port forwarding number of a 2300. Using the example above, the external
IP address of the 2300 then becomes 24.148.220.199:5000.
4. At the local display click on the Menu button. Select Advanced Menu > Network Setup > Web
Server Port.
5. Enter the port number (in our example—5000) and click the DONE key.
