1.1 Introduction of Maintenance Tools
The Maintenance Tools are comprised of the On-Line Monitor and the Off-Line Monitor.
The following three connection methods are available in the Online Monitoring.
(1) Monitoring by connecting the maintenance tool to MN converter (CMS-MNF,CMS-MNF-B,CMS-MNG-E)
via RS-232C.
(2) Monitoring by connecting the maintenance tool to MN converter (CMS-MNG-E) via USB.
(3) Monitoring through the central controller (G-50A) by connecting the maintenance tool to LAN.
A brief explanation of each of their function is provided here.
1.1.1 On-Line Monitor(via MN converter)
The On-Line Monitor is connected to the unit by a MN Converter (CMS-MNF,CMS-MNF-B,CMS-MNG-E)
and can monitor such areas as system data, unit data and operating data.
(1) In case for local connection (via RS-232C)
Connecting PC installed with the maintenance tool to M-NET transmission line via MN Converter allows
conducting various monitoring and setting from the Maintenance Tool.

* To use the maintenance tool via G-50A (Network), license registration for the G-50A to be used is necessary.
Purchasing the license No. for each G-50A to be used, conduct the license registration through the Web
browser (http://[IP address of the G-50A]/ administrator.html). After selecting "Maintenance tool" of the optional
function on the Web Browser Screen displayed, enter the purchased license No..
For the detail of the license registration, see Chapter 4 [Registering a License for Optional Functions] of Central
Controller Model: G-50AWeb Browser Operation Manual (For manager).
NOTE:
•When the MN Converter (CMS-MNG-E) is being used in Remote Error Notification mode (see section
3.12), you cannot connect to the MN Converter (CMS-MNG-E) via RS-232C. Connect via USB.
NOTE:
•You cannot connect to the MN Converter (CMS-MNG-E) via RS-232C and USB at the same time.
Doing so may result in malfunctions.

1.1.2 On-Line Monitor(via G-50A)
The On-Line Monitor is connected to the unit by the central controller(G-50A) and can monitor such areas as
system data, unit data and operating data.
(1) In case for local connection
By directly connecting the PC installed with Maintenance Tools and G-50A through LAN, various
monitoring/setting can be performed from the Maintenance Tools.
(2)-1 In case for remote connection (Dialup connection mode)
By connecting the PC installed with Maintenance Tools and G-50A through public network remotely, various
monitoring/setting can be performed from the Maintenance Tools.
(2)-2 In case for remote connection (E-mail connection mode)
Under E-mail connection mode, communication can be executed with G-50A through E-mail transmission
via mail server. All communication with G-50A is converted into E-mail in this case.

NOTE:
•To use the E-mail connection mode, the version of G-50A should be above 2.60.
•When using E-mail connection mode, the local G-50A is required to be initially set with Maintenance Tool and
the mail address by the G-50A initial setting tool.
- For each mail address, it is required to obtain and set an exclusive one. To transmit mail via an internet
provider, obtain the mail address from the provider. When a mail server is existing on the LAN, obtain the
mail address from the LAN administrator.
- Set the [Pop receive interval] within 3 minutes. However to monitor operating status [Operation Monitor], set it within 1
minute.
- Setting of initial information to G-50A can not be executed from Maintenance Tool. Make sure to set it from the G-50
A
initial setting tool locally. If dialup connection environment is available, it can be set from a remote position.
(For detail, please refer to 6-1 Mail Basic Setting in the instruction manual of the G-50A initial setting tool.)
•The communication speed under E-mail connection mode largely depends on the transfer rate of each mail
server. Under the circumstance, the action of Maintenance Tool may take a lot of time under some internet
environments or routing mail servers.

1.1.3 Off-Line Monitor
The Off-Line Monitor can display, print information obtained by the On-Line Monitor.
In the case of connection monitoring utilizing G-50A, the operation monitor data collected by G-50A will be
transmitted to remote mail servers periodically if the [Operation monitor - mail communication mode] of online
mode is adapted.
Using this function allows to collect and monitor the operation monitor data without continually connecting the
Maintenance Tool.
*For the setting of the [Operation monitor - mail communication mode], refer to 3.7.1 and 4.3.3 description.
*Image of the [Operation monitor - mail communication mode]
1.1.4 Wide area access mode
The “Wide area access mode" has been located starting from Ver4.06(D).
Under the "Wide area access mode," the access method for remote connection can be registered to the
database of each customer enabling easy online connection with the air conditioning system of the customer
desired to be accessed.
[Remote access method]
- LAN : Accessing by directly connecting Maintenance Tool PC and G-50A with LAN (WAN).
- Dialup : Accessing by dialup connection to G-50A via public network.
- E-mail : Accessing by E-mail communication to G-50A via mail server.
- Modem (MN Converter) : Accessing by connecting Modem to MN Converter via public telephone circuit.
After the online connection performed by any of the above methods, you may use the similar function as that
obtainable in the normal online connection.
While under the offline mode, customer information will be provided to the monitored data enabling only to
select a specified customer for display.

When PB is chosen, "ATDT" is added before the
telephone number.
For example, when a telephone number is
0123456789,
"ATDT0123456789" is transmitted to the modem.
It becomes the following when "DP", "NONE" are
chosen in the same way.
DP --- ATDP0123456789
NONE --- ATD0123456789
When a circuit connection is impossible in the case
of above three which as well, "ELSE" is used.
When "ELSE" is chosen, nothing is added to before the telephone number.
Input a command for the circuit connection from the beginning.
For example, "ATD0,0123456789" is transmitted to the modem when "ATD0,0123456789" is
inputted in the telephone number column.
When the one except for the "ELSE” is chosen, only a number can be inputted in the telephone
number column.
The information for up to 100 customers can be registered. When the information for 100
customers has been registered, new customer information cannot be registered. Delete the
unwanted customer information using the customer selection screen.
(c) Check the contents, then click on .
The Connection Status Indication Screen will appear.
Connect the line. When you want to disconnect the line,
