2. How long can the AquaController's serial cable be?

The maximum length serial cable is about 100 foot. You can buy a shielded serial extension cable at your local computer store. It should be a straight-thru cable with a male DB9 connector on one end and a female DB9 connector on the other, so that it can be directly connected to your PC and the AquaController serial cable we sell (part #SERPC9). NULL-modem cables will not work as an extension cable as their internal connections are incorrect.

If you wish to build you own extension cable pins 2, 3, 4, and 5 should be connected straight-thru on each of the DB9 connectors. Be sure to use shielded cable especially for longer cable runs.

3. Why can't I control anything with my AquaController?

There are many reason's why the AquaController cannot control anything. Please go through the list below to find common problems.

  1. Make sure that the AquaController is connected to the control interface with a four wire telephone cord. Many telephone cords only have 2 internal wires.
  2. Make sure that the X10 addresses on the dials of the modules match the X10 addresses in the AquaController. The AquaController's address can be viewed and modified in the setup->timer setup->timer names->modify timer names menu
  3. The light on the control interface is usually on and blinks off when X10 commands are sent from the AquaController. Make sure that the control interface light blinks off when you send an X10 command from the AquaController. This can be tested on the AquaController's Control & Status->Manual Control menu.
  4. Some expensive power strips have active noise suppression and can attenuate the X10 signal so that is not reliably received by the control modules. Usually power strips that cost more than $35 may have this feature. Buy power strips that cost less than $15.00 and you can be reasonably sure that they will not cause any problems. Both Home Depot and Walmart sell inexpensive power strips ($15.00) with extra spacing between the plugs and can accommodate 6 control modules per power strip.
  5. The control interface and the control modules should be plugged into the same phase of power to ensure that the X10 signal is reliably transmitted. This is usually easily accomplished by ensuring that the control interface and all modules put into the same circuit. If the control interface and control modules are on different phases of power, then a signal bridge (SBLEV) will need to be installed at the breaker panel.

4. Why do my power compact florescent lights turn on when they should be off?

The CM466 control modules have a feature called 'local control', which allows the control module to turn on when it detects that the appliance plugged into it has been manually turned on. To the control module, some electronic ballast appear to be going from off to on and so the module turns itself back on even though it has not received any X10 commands to do so. There are two options to solve this problem.

  1. Plug an additional load (i.e. fan, AC transformer, etc.) in parallel with the problem ballast
  2. Perform surgery on the control module to disable the local control feature. Follow the steps below:
    1. Use a Phillips screw driver to remove the screw between the plugs of the module
    2. Carefully pull the plastic clam shell apart. Be careful to not loose the X10 address setting dials
    3. Remove the printed circuit board from the plastic clam shell assembly.
    4. Refer to the diagram below and cut the wire jumper with dikes.

      X10 Pro Module PSC02
    5. Install the printed circuit board into the plastic clam shell assembly.
    6. Put the plastic clam shell back together making sure that the X10 address setting dials are properly seated
    7. Use a Phillips screw driver to install the screw between the plugs of the module

5. Why are the pH and ORP readings on my AquaController are inaccurate or erratic?

If the serial cable is to be permanently attached between the AquaController and the PC, a Ground Isolated Serial Connector (SERIPC9) is recommended. The isolator will eliminate potential ground loops between the AquaController and the PC. Grounds loops may cause erratic and inaccurate pH and ORP readings. The ground isolated serial connector is available from either your local aquarium shop or from Neptune Systems directly.

6. How should I mount my pH, ORP, and temperature probes?

One economical and practical way to mount the probes is to simply float them in the sump with a block of styrofoam. Take a piece of styrofoam and make holes in it slightly smaller than the diameter of the probes. Push the probes halfway through the foam and float the whole assembly in the sump.

7. How do I configure my AC3 or AC3PRO Ethernet connection?

First you need to get the settings for your local network – you can do this by bringing up a command shell on your PC (type cmd in the start->run window of your PC). In the cmd shell type ‘ipconfig /all’ – This will display your internal IP address, netmask, default gateway, and dns server.

1. Connect the Ethernet cable between the AquaController's Ethernet port and your router/hub/switch's Ethernet port. If the connection is good both the green and yellow LEDs on the AquaController's Ethernet connector should lite. The green LED will blink when there is network traffic.

2. Enter the netmask, default gateway, and dns server into the AquaController’s network setup menus. This information is entered in the setup->net setup menu on the AquaController 3. The IP address should be unique and different then your PCs – most likely you’ll only change the last 3 digits of the address. For example if your computers IP address is 192.168.1.101, then set the AquaController's IP address to 192.168.1.50.

3. Power cycle or restart (setup->netsetup->restart) the AquaController.

4. The controller is accessed through your internet browser by typing in the IP address of the controller in the address field of your browser. In the above example you would use 192.168.1.50.

Once that works then you can configure your router so that the AquaController can be accessed from the internet. Follow these steps:

1. Configure your router so that WAN side port 80 tcp requests are sent to the AquaController's IP address on port 80 (External port is 80, internal port is 80, and the internal IP address is the AquaController's). This configuration is usually done in the router's virtual server setup menu, port forwarding, or the UPnP section of the router. Consult the routers manual for details. Note that some routers (Linksys) have global enables for UPnP or port forwarding, so be sure to turn this on or your router will not forward port 80 to the AquaController.

2. Change the administrator user name and password of the AquaController. See setup->netsetup on the controller.

3. To access the controller from the internet you need to know your WAN IP address; the WAN IP address can be found by going to www.whatismyip.com. This is the IP address that will be entered into the address field of your browser when trying to access the controller from the internet. If your internet connection has dynamic IP address, then sign up for a free account at www.dyndns.org and following the installation instructions. The dyndns account will allow access your controller using a consistent DNS name even though the IP address may change. Note that some routers (DLink for example), have built-in support for dyndns accounts so no client PC software is required.

Note: Some ISPs block incoming port 80 requests, so you you will have to use a different external port number. In this case you would configure your router to route a different incoming port like 4567 (or any other 4 digit number) to port 80 of the AquaController's IP address. If this is the case in your router's port forwarding, or UPnP section configure the external port would be 4567, internal port 80, and the internal IP address of the AquaController. If your isp blocks port 80 then you would need to enter the address as http://123.45.67.111:4567 - substitute your internet IP address for 123.45.67.111.
