(3) In the [Internet Protocol Version 4 (TCP/IPv4) Properties] window,
check the radio button next to [Use the following IP address].
Enter [192.168.1.*] in the [IP address] field. (The number indicated
with an asterisk must be different from the IP address of the
AE-200/AE-50/EW-50 to be updated.)
Leave [255.255.255.0] in the [Subnet mask] field as it is.
Note: If the IP address of the AE-200/AE-50/EW-50 is [192.168.1.1], set the
same 1st, 2nd, and 3rd numbers and different 4th number, such as
[192.168.1.2].
Note: Default IP address of AE-200, AE-50, and EW-50 is [192.168.1.1].
Note: When performing an update on a PC that is already connected to the
existing LAN, [255.255.255.0] may not appear in the [Subnet mask]
field. When [255.255.0.0] appears, enter the same 1st and 2nd numbers
(192.168) and different 3rd or 4th number of the IP address of the
AE-200/AE-50/EW-50 in the [IP address] field.
Caution:
Obtain an approval from the client for the following precautions as necessary.
1. The communication between AE-200/AE-50/EW-50 and the air conditioning units will stop while
the software is being updated. Although the unit in operation may detect a communication error
and an error sign may appear on the local remote controllers, the unit will continue its operation
and be operable from the local remote controllers.
* Note that Mr. Slim indoor units or systems with no local remote controllers may detect a communication
error and come to an abnormal stop.
2. Record the operation status of the air conditioning units immediately before updating the
software. After the software update completes, check the operation status of the units, and
manually operate the units as necessary.
3. Some operations and functions, such as scheduled operations, billing function, Peak Cut control,
energy management function, will be disabled while the software is being updated. Check the
setting details of these functions beforehand, and update the software when it does not affect
these functions.
4. If the functions in the table below are used on the TG-2000A, avoid updating the software during
the time period indicated in the right column.
TG-2000A function in use
Electricity charge apportioning function

5. CSV output data (e.g., energy management data) will lose up to 60-minute worth of data.
6. When a built-in PI controller is used, pulse signals cannot be input while the software is being
updated.
