Channel protocol for logging
in to the back end.
If the MDU is directly connected to a computer, the IP address can only be
allocated manually. The IP addresses of the MDU and computer must be in
the same network segment, and must be different.
If the MDU is connected to a computer through a LAN switch or router with
the DHCP function, the IP address can be allocated manually or automatically.
Manual allocation is used by default.
– Manual: Check that their IP addresses are two different values on the
same network segment. Set the SmartLi IP address to be in the same
subnet as the PC IP address. Perform the bitwise AND operation for the
UPS IP address and the PC IP address with the subnet mask respectively.
If the operation results are the same, the two IP addresses are in the
same subnet.
AND operation rule: 1 AND 1 = 1, 1 AND 0 = 0, 0 AND 1 = 0, 0 AND 0 =
0. That is when the corresponding bits are both 1, the result is 1. In other
cases, the result is 0.
