the system from the [Logon] screen.
There will be no password at the initial start of the
system. Click the [System …] button and make the
following settings.

Periodic Scan Settings

Set the periodic scan time and the sites to be scanned.

Initial Password Settings

Register the password. After registration, log in with
this password.
Do not forget the registered password.

c) Configuration Scan

Select [Scanning] and [Start] so that the [Manual
Scan] dialog will appear. Check the [Configuration
Scan] and click the [OK] button. Execute the scan­ning of all the registered sites and collect the latest
information. Unless the [Configuration Scan] is
checked.
Unless [Configuration Scan] is checked, the normal
scanning of the site appearing in [Scan Site] will be
performed with no collation of setup information.

Note: Do not use commas for character strings.

SiteName, Adapter No, LineNo,Name

SiteName: Site name (See note 1) (32 bytes max.)

Adapter No: Connected adapter number (0 to 3)

LineNo: Adapter port number to which the air

conditioner is connected (See note 2).

Name: Name (See note 3) (16 bytes max.)

Note 1: The site name set for SiteInfo.cfg must be used.
Note 2: If 0, 1, 2, or 3 is specified for LineNo, the air

conditioner name for each line will be set. If -1
is specified, the adapter name will be set.

Note 3: A user-defined alphanumeric character string

can be specified.

7

A DS-NET setting mistake or a site (adapter) prob­lem may be considered if an error (e.g., a commu­nication error) occurs in the process of scanning. In
that case, check the cause of the error.

Note: If new registration or any change is made, be

sure to perform an configuration scan to
match the setup conditions with each site’s
settings. The configuration scan will require a
period determined by the number of adapters
on all the sites multiplied by approximately
10 seconds.

d) Detailed Settings

Make system settings and adapter settings for each
site.

e) Backup Recommendation

After all items are set and confirmed, stop the
DS-NET once. Back up the DS-NET destination
folder and subsequent folders then.

Note: The DS-NET accumulates the latest informa-

tion and log data during daily monitoring. In
order not to loose the information due to acci­dents, such as PC failures, it is recommended
to back up the information on a daily basis.
Each type of DS-NET file can be copied while
the DS-NET is running.

4-3-2. Checks on Startup Failure

Mistakes in DS-NET settings or site adapter and
modem connections are considered if the DS-NET
does not run.

• No communication at all: Mistakes in connections
to the COM1 port of the modem or power supply
are considered.

• No communication with specified sites: Mistakes in
DS-NET settings for site phone numbers are con­sidered.

• Communication error in specific air conditioner:
Mistakes in line number settings are considered.

• The following jobs are required after adding or
removing air conditioners or making wiring
changes.
[Site side]
Reset the power supply to the DS-NET.
[PC side]

• Finish the DS-NET.

• Delete the corresponding site from SiteInfo.cfg.

• Start and finish the DS-NET. This clears only

data on the corresponding site in DSNET.dat.

Local Control

Automatic Alternate Operation

According to the number of air conditioner systems connected and the minimum guaranteed number of units in
operation, all the air conditioners are operated and stopped at certain intervals (alternate operation intervals) so that
the operating hours of each air conditioner can be equalized.
Automatic alternate operation of the air conditioners is not performed while air conditioner errors are detected.
When the air conditioners are in automatic alternate operation, the air conditioners may not respond to the remote
controller or remote instructions.

Note:
When the forced operation signal is input, all air conditioners will be in operating mode, and the air conditioners will
start forced operation, to which priority is given over automatic alternate operation, the remote controller, or remote
instructions. The foregoing applies to the forced stop signal in the similar manner. Higher priority is given to the
forced stop signal over the forced operation signal.

Backup Control Operation

Overview

If an air conditioner comes to a stop due to a power failure or malfunction (excluding any alarm or warning),
another air conditioner will be operated in order to keep the number of air conditioners in operation.

If the air conditioner that has come to a stop starts operating again, one of the air conditioners in operation will
be stopped so as to keep the number of air conditioners operating before the occurrence of the power failure or
malfunction.

Remote controller operation may be ignored while the backup control operation is active.

20

Sequential Start Control Operation

Overview

A very high starting current will flow immediately after the DS-NET software transmits a start instruction simul­taneously to all the air conditioners connected to the DS-NET Adapter units and the air conditioners start oper­ating together. The sequential start control operation adjusts the start timing of each air conditioner to suppress
the starting current and prevent all the air conditioners from starting simultaneously.

• The sequential start control operation is available only if the system is connected to the PC to execute the
DS-NET software.

• The sequential start control operation does not work for Personal Home Use with the GSM modem employed.

• The sequential start control operation adjusts the start timing of each air conditioner and prevents all the air

conditioners from starting simultaneously.

• The DS-NET software cannot make setting changes to enable or disable the sequential start control operation.
Use the remote controller in service mode instead. For details, refer to the Installation Manual.

Start Timing of Sequential Start Control Operation

• The DS-NET Adapter starts each of the connected air conditioners in sequence at approximately 4-second
intervals after a delay according to the adapter address (ADR) when the start instruction is received.

• The delay time is a minimum guaranteed time, which may be extended according to the connected system or
operation timing.

Forced Start/Stop Operation

Overview

Air conditioners can be forcibly started or stopped with an external forced start or forced stop signal input into
the DS-NET Adapter.
Priority will be given to the forced stop operation if forced start and forced stop signals are input simultaneously.

Contact type: Normally closed
Detection condition: Level sensing

Forced Start Operation

When the forced start signal is ON, all air conditioners connected to the DS-NET Adapter will be set to run state.
Furthermore, if a stop instruction is transmitted from the PC or stop operation is performed by the remote controller
while a forced start signal is ON, priority will be given to the forced start operation and the air conditioners will operate.

The air conditioners started with a forced start signal turned ON will continue operating when the forced start sig­nal is turned OFF.

The following conditions, however, apply.

• If a forced stop signal is ON, priority will be given to the forced stop operation.

• If a malfunction occurs, priority will be given to the stop operation activated with the malfunction detected.

Forced Stop Operation

When a forced stop signal is ON, all air conditioners connected to the DS-NET Adapter will be stopped.
Furthermore, if a start instruction is transmitted from the PC or start operation is performed by the remote controller while a
forced stop signal is ON, priority will be given to the forced stop operation and the air conditioners will be stopped.

The air conditioners stopped with a forced stop signal turned ON will be continuously in the stop state when the
forced stop signal is turned OFF.

The following conditions, however, apply.

• The forced stop operation takes precedence over the forced start operation.
