Question
What is maximum number of controllers that can be connected by daisy chain on a MSM installation?
Summary
max number of controllers
Answer
The max number of controllers allowed on an MSM network is linked to the sub mask configuration, and can generally go up to 255 devices.
Since the limitation is on the number of devices on the same subnetwork, it does not matter whether these devices are from Hach or not.
The Wi-Fi technology uses the same TCP/IP protocol as LAN, so the same device limitation exists on either LAN or WiFi.
