You can update the FW on the slave doser if you want to have the magnetic stirrer feature available to you.
The slave doser connects to the standalone doser with a PAB cable. Once connected, you can access the settings all from the standalone doser connection. No additional COM ports are needed.
I know it's probably been stated before somewhere but I'm having a hard time setting up the unit. I downloaded the software on my phone, note 4, and when I pull the app up it says Name: and Host:. What do I enter for these? I have the doser hooked up to my phone through the usb, I have a micro usb converter. Any suggestions?
