NodeGrid Serial Console supports DialUp via USB modems. It does not support via serial ports.

You can plug any USB modem such as Zoom or USRobotics  to any of the NodeGrid Serial Console USB ports.

Then, follow the steps below:

a.       Log in as admin to the NodeGrid WebUI

b.       Go to System, Dial Up page

c.       Under Services tab, enable PPP connection

d.       Under Devices tab, click on Add button

e.       Complete the parameters accordingly. The “Detected Devices” should show something like ‘usbM1-4’

f.       After the parameters are complete, click on Save. (NOTE: leave “PPP Dial-Out Phone Number” blank if you want it to be Dial-IN; if you want it to be Dial-OUT, then add the phone number)

g.       Add callback users and phone numbers under CallBack Users tab, if that is the case.
