 A maximum of 200 devices can connect to a single SmartLogger. You are advised to connect fewer
than 30 devices to each RS485 route.

The IP addresses for all devices in the daisy chain should be within the searching segment set in the
SmartLogger and they must differ from each other. Otherwise, the communication would fail
between the devices and the SmartLogger.
 You can perform the Auto Assign Address operation on the built-in WebUI of the SmartLogger. If
an RS485 address conflict is detected for SUN2000s, the SmartLogger automatically reassigns
addresses without the need for local address upgrade for the SUN2000s.
 The values of Baud rate for all the devices in each daisy chain should stay consistent with the baud
rate of the SmartLogger.
