controlling Doser2

[firefish128]

Does any of the products GHL puts out automatically install the drive so it works on the first try? can somebody please walk me thru the manual install of the driver for the doser2? Thank you

Hi,

The Doser 2 driver should automatically install itself when connected to your PC for the first time. If it does not, please follow these steps:

1. Go to “This PC” or “Computer” and click on your hard drive which may be labeled as “(C:)”
2. Click on “Program Files (x86)”
3. Click on “GHL ControlCenter_V1xxx” (Your current version of GCC)
4. Click on “Driver”
5. In that folder, you will see two files. One is named, “dpinst_x64” and the other is
“dpinst_x86”
6. Click on one of them and follow the install command prompts.
7. After the driver has installed, you should restart the computer and try to connect to your Doser 2.

I have a detailed user manual I can email you: Please send me an email at info@ghlusa.com

a few observations
it says program files but no (x86)
GHLcontrol center VX1057, correct program? works with my LEDs
dpnist_x64 will nor run on my computer, it says to find a version for the PC check with the software publisher
dpnist_x86 did install, but still won't connect

GHL Control Center V1057 is an outdated version.

Download the newest version of GHL Control Center and please try again:

It would also be good to update to FW version 1.19 which is included when you download GHL Control Center.

downloaded new control center, everything works, programmed dosser, not dosing the correct amount. calibrated the pump at least 15 times, set pump #1 to dose 6ml, 3 times a day, starting at 7am, the next morning control center shows it dosed 3 times and 6ml subtracted from the container, physically there is only 4 ml in the container (I'm dosing into a 20ml syringe to verify the dose). same with pump #2, dosing 20ml over 24 hours, only fills syringe to the 18ml mark. any way i can correct this? i updated the firmware on the pump current version is 1.19

When you calibrate the pumps, it is important to make sure that all the lines are fully primed and without any air bubbles in the lines. You may see a small air gap at the start of the tubing and that's okay, but anything more than that should be removed.

We also advise that you use a graduated instrument such as a graduated cylinder.

[firefish128]

no air in the system, is there anything else i can check? the syringes I'm using are graduated in 1ml increments so they are pretty accurate.

Good morning gentlemen, thank you for replying to my last thread so quickly. Ive been trying to program the doser for the past week and it still not dosing the correct amount. Im trying to dose 6ml on pump #1 and 20ml on pump #2. 2ml dosed 3 times a day on pump 1 and 2ml dosed 10 times a day on pump2. after 24 hours pump 1 has 5 ml in it and pump 2 has 17ml. the remaining fluid in the container also corresponds to the amount dosed. If its dosing 2ml how do i end up with an odd number left in the container?
Calibrating the pump; I'm supposed to put the amount of ml the pump doses in the calibration cycle, which is 1 minute. my pumps are running for a minute and 6 seconds! is there a programing problem or am i missing something? any suggestions? Thank you

[firefish128]

3 weeks and no answer?

[firefish128]

Gentelmen: I have been letting the doser run for the last couple of months, yes it does dose, but not at the correct dosages, it seems to be a programming problem. any suggestions please? thank you

[Vinny]

Please update to firmware 1.20 and let us know if you're still having those issues.

[firefish128]

where can I find the firmware update?

[firefish128]

unable to locate on the download page

[firefish128]

installed new firmware on control center, new firmware showed up as available on doser, everything upgraded calibrated pumps. Pumps do now run for one minute, will let you know on dosing accuracy!

Thank you very much for the help!!
