PART 1: The basics

In this section we will cover the basics:

  • Overview of each connector on the IOND
  • How to power ON the device
  • How to connect PAB cable to device
  • How to assign IOND to your primary device

Unpack the contents of your ION Director set box
Inside the box you will find the following:

ION DirectorIOND MUI sensorFlex PVC tubing 8m (26’ 3")Water sample filter
Reference A fluid (500mL)Reference B fluid (500mL)Pre-drilled capsPower splitter cable
GHL Doser 2.2 SA or EXT (if set purchased)24V PSU (if set purchased)PAB cable (if set purchased)

For the initial setup (part 1) you will need:

Contents of IOND boxFor connecting IOND device and doser
IOND EXT set owners: Additional PAB cableFor connecting IOND/Doser to a ProfiLux or SA Doser
Need an extra PAB cable?
If you purchased a ION Director EXT set, you will need an additional PAB cable. This cable will be used to connect this set to your master device. PAB cables are offered in various lengths and can be purchased from your preferred GHL dealer or at the GHL store.


— IOND ports overview

A: 24V power port
B: Connection for GHL MUI sensor
C: Vent / Return line to aquarium
AUX port for future expansion options
PAB ports for connecting IOND and Doser together. Also used for expanding GHL system with other PAB devices.

IOND and GHL Doser 2.1 shared PSU

As you were going through the contents of your IOND box, you will see that your IOND did not include its own power supply and instead it came with a PSU splitter cable. This cable is used to connect the IOND and Doser to the 24V PSU that belongs to the doser itself. In other words, both devices share the same 24V power supply.

A: Water sample inlet/outlet is used for feeding the IOND a sample of your aquarium water and returning old tank water before the start of each measurement

B: Reference A inlet is used to feed reference liquid into the IOND during measurement

C: Reference B inlet is used to feed reference liquid into the IOND during measurement

D: Waste water outlet were water is pulled OUT of the IOND after measurement is completed

IOND sensor port

On the right-side of the ION Director, you’ll find the port for the GHL MUI sensor. Here is where you will be installing the sensor later-on in the setup process.

Now that we’ve explained the purpose of each port, the next step will be to find a suitable location for the IOND, then power ON both devices and connect the PAB-cable to each device.

— Find a suitable location for your IOND

To ensure safe and hazard-free operation, the following regulations must be followed! Failure to follow the safety guidelines will result in VOIDING your warranty. The manufacturer rejects any responsibility or liability for damages resulting from misuse!

Make sure that the IOND cannot be affected by electromagnetic interference sources!

Why IOND placement is important…

The ION Director® is a highly sensitive electronic measuring device. To accurately determine ion concentration, it measures extremely low voltages with an accuracy of 10μV (that’s a ten-thousandth of a volt). Although the IOND electronics is designed to be as interference resistant as possible, electromagnetic interference can significantly disturb the measurements.

We therefore recommend placing the ION Director® as far as possible from potential sources of interference. Sources of interference are:

  • Power supplies, ballasts, drivers
  • Fluorescent and gas discharge lamps
  • LED lights
  • Pumps and other motors
  • Other electrical and electronic devices
  • Electrical cables to above mentioned sources of interference
For more information on placement…

We highly recommend reading the IOND manual, pages 15 – 17.

— Power ON devices and connect PAB cable

Power ON devices

  1. Take the power supply splitter cable and connect the Y-ends to the ION Director and Doser
  2. Connect the tail-end of the splitter cable to the 24V PSU.

NOTE: Make sure you connect ONLY the IOND and Doser to the 24V PSU!

Connect PAB cable to IOND / Doser

Standalone IOND set owners

  1. Take the 1 PAB cable that was included in the box and connect it to the IOND and Doser.

IOND EXT set (For ProfiLux or Doser SA owners)

  1. Take the 1 PAB cable that was in the box and connect it to the IOND and Doser.
  2. Take the 2nd PAB cable and connect one-end to either the IOND or Doser. Take the other end of the 2nd cable and connect it to your primary device.
Now that both the IOND and Doser are powered ON and connected with a PAB cable, the next step will be to connect to your SA Doser or ProfiLux controller using the GHL Connect app.

— Download GHL Connect and connect to primary device

  1. Using your phone or tablet, open up the Google Play store or Apple app store and do a search for GHL Connect.
  2. Once you’ve found the app, download it and open it up.
  3. You will be greeted by the initial setup screen. Follow the on-screen prompts until you get to the My Devices page

IOND EXT set owners

  1. Connect to your primary device using the GHL Connect app

Standalone IOND set owners

1. Connect to your doser’s hotspot network by using your phone or tablet to search for nearby Wi-Fi networks. You will see the GHL-DOSER2 hotspot signal. Select it and wait for your phone or tablet to connect. Once connected, go back into the app.

2. Press ADD device, select the Doser 2, then press NEXT.

3. Leave the “Configure connection” page as-is and press NEXT.

4. Type-in the name you want to give to this doser connection, then press DONE

5. When this message appears, press Continue offline. Your new connection will now be listed. Select it to connect.

Once you see the Dashboard, you are officially connected to your primary device!

Standalone IOND set owners: CONTINUED

If you have a Standalone IOND set and are connected to your Doser SA, the next step for you will be to set the time, date and time zone.
  1. Press the Menu icon and select General
  2. Set the time and date
  3. Set the time zone based on your location

NOTE: The time zone settings allow the IOND to show you the correct date and times of each test

Optional: If you’d like to set an audible alarm or PIN code, you can set that up on the same page

4. Press SAVE

— Assign PAB device

The next step will be to assign the IOND to your primary device. If you have a IOND EXT set, you will also be assigning the EXT doser that was included with the set.

If you purchased a Standalone IOND set, READ THIS!!!

If you purchased a SA IOND set and plan to connect the SA Doser and IOND to an existing SA Doser or ProfiLux (3 / 4) controller, you must first set this SA Doser to EXT MODE before proceeding any further with IOND setup.

This will allow your existing SA Doser or ProfiLux (3 / 4) to control the SA Doser (to be converted to EXT mode).

Click here to learn how to convert a Standalone Doser to EXT mode.

Once the SA Doser from the IOND set is converted to EXT mode, you can proceed with the steps below.

  1. Press the Menu icon and select System
  2. Press Assign and configure connected PAB-devices
  3. Press Assign devices

You will now see a list of devices which have been detected by your primary device.

4. Select the IOND and EXT doser (if you have one).
5. Press SAVE, then confirm by pressing YES

Your devices have now been assigned.

IOND EXT set owners: Set EXT pump numbering

If you have a IOND EXT set, reconnect to your primary device and go back to the PAB settings page. You must now assign the pump numbering of this newly added EXT doser. Press the Menu icon, select System, select Assign and configure connected PAB-devices, press the blue-gear icon to the right of the doser and set the starting number of this dosing unit.

For example, if your primary device is a Standalone Doser 2.1, the numbering for those pumps are already assigned to dosing channels 1-4. By adding a second doser 2.1, the numbering of this doser should be set to begin at dosing pump channel #5. That way, your main doser controls dosing channels 1-4 and your second doser controls dosing channels 5-8.

ION Director Initial Setup (Part 2)

Now that you’ve completed part 1 of the step, you can move onto part 2 which shows you how to cut and install the including tubing, install the water sample filter and calibrate pump heads.
