Cascade device address assignment
Symptom: The indicator flashes (1s on and 1s off) or via close-loop
communication, the host computer indicates address assignment failure
Inspection steps:
(1) first check whether the number of cascade units exceeds 16pcs - product
design only supports a maximum of 16 cascade units.
(2) then check whether the cascade is connected in the correct order - the
correct order is the previous module link1 to the next module link0.
(3) re-plug the cascade internal communication wire in order to observe
whether the final number of assigned devices via CAN BUS/Bluetooth/RS485
and the actual number of connections are consistent.

Cascade equipment in operation
Symptom: Protocol communication or the host computer indicates that a
device is offline
Inspection steps:
(1) check the communication or the history of the host computer to determine
whether the device is in the state of under voltage protection before it goes
offline - the device will enter into sleep mode after under voltage protection, it
is necessary to re-charge the battery at earliest.
(2) If the state before the device dropped is normal and there is no
undervoltage protection, check whether the device link port wire is loose or
connection problem.
Symptom: Communication with the first devices via CAN
BUS/Bluetooth/RS485 is interrupted
Inspection steps:
(1) check whether the communication wire connection with the first battery is
loose.
