How to Add a Slave Doser to a SA Doser or ProfiLux

If you purchased a GHL Doser 2.1 Slave, you can connect it to the standalone GHL Doser 2 or 2.1. The slave Doser 2.1 can also be connected to a Profilux 3 or 4 controller.

A slave doser can be daisy chained via a PAB cable; a GHL Doser 2 SA or 2.1 SA or Profilux 3 or 4 must be present. Please note that a PAB cable is not included with the slave doser and will therefore be needed before continuing with this setup. To add a GHL Doser 2 or 2.1 Slave to an existing standalone Doser 2 or 2.1 or Profilux 3 or 4, please follow these steps:

1. Connect all cables and tubing to the slave doser. 2. Connect the Slave Doser 2 to a GHL Doser 2 SA using a PAB cable. 3. Connect to the Standalone Doser 2 using GHL Control Center. 4. Click on “System” 5. Click on “Assign Devices”. A new window will pop up and your slave Doser 2 will be

Doser 2.1 Manual

Assigning a correct IP address

During Standard Wi-Fi connection setup, when you are asked to select an IP address, make sure you select a number within your network’s DHCP range. This range is commonly provided by GCC during the setup steps.

● If you decide to not use the IP settings setup wizard, make sure that the first 3 IP address fields are the same as your Default Gateway. For example, if your Default Gateway is 192.168.1.1, you MUST fill in the first 3 fields into the assigned doser IP address, 192.168.1.xxx - The last field can be a number that is not assigned by another device on your Wi-Fi network.

Confirming doser connection to your network via LAN or WiFi

1. Type into your windows search bar, cmd and select windows command prompt. 2. Type in “Ping (YOUR DOSER’S IP ADDRESS GOES HERE)”, press enter.

○ For example, if your doser’s IP address is 192.168.1.150, to ping it, type in “Ping 192.168.1.150”

3. Successful communication to your network will result in the outcome below. 4. If this does not show, you may want to assign a new IP address to your GHL Doser

2.1.
