I own a GHL 2.1 stand-alone dosing pump. Ive had it for about 1 year and mever had an issue until now. I recently made some changes in the scheduling and now the doser stopped working and I could no longer access it through the app. It reads that it is connecting, but it never does. It does work manually. I've tried deleting the device and the app, but that hasn't worked. I've reached to GHL twice, but they're not very responsive. It was a VERY expensive unit and I'm not thrilled about the idea of having to purchase another. Any help offered would be greatly appreciated.

Do you have access to a PC running Windows or a windows simulator on a MAC?

Is it a model that have a LAN input? Red - LAN Blue USB

Its a possibility that you of mistake have change it from a SA to a slave (or extended). If so - you need to access it with GCC and USB

Hi Lasse. Yes, I do. I tried connecting via USB last night, but my computer wouldn't download the file needed. It is an old and outdated PC.
