<CR> Carriage return character, which value is specified with command S3.

<LF> Linefeed character, which value is specified with command S4.

<...> Name enclosed in angle brackets is a syntactical element.

Brackets themselves do not appear in the command line.

[...] Optional subparameter of a command or an optional part of ME information

response is enclosed in square brackets. Brackets themselves do not appear in the
command line. When subparameter is not given in parameter type commands, new
value equals to its previous value. In action type commands, action should be done on
the basis of the recommended default setting of the subparameter

underline Underlined defined subparameter value is the recommended default setting of this

subparameter. In parameter type commands, this value should be used in factory
settings that are configured by V.25ter command &F0. In action type commands, this
value should be used when subparameter is not given.

List of AT-commands

Commands always start with AT (which means ATtention) and finish with a <CR>
character.

Information responses and result codes

Responses normally start and end with <CR><LF>, except when the modem is set to
“short result code format” with the command ATV0, or when the ATQ1 (no result
codes) command is used.

If command syntax is incorrect, an ERROR string is returned. If extended error result
codes are configured (+CMEE) and if command syntax is correct but with some incor­rect parameters, the +CME ERROR: <Err> or +CMS ERROR: <SmsErr> strings are
returned with different error codes. If the command line has been performed successfully,
an OK string is returned. In some cases, such as “AT+CPIN?” or (unsolicited) incoming
events, the product does not return the OK string as a response. In the AT-command list
below, <CR> and <CR><LF> are intentionally omitted.

Special AT-commands

In addition to the commands listed below there are two special commands that do not
start with AT.The first command is “A/” without any <CR>.This command makes the
modem repeat the last entered command.The second special command is the “+++”
(also without <CR>).This command is called “escape sequence” and is used when the
modem is in dedicated mode (online mode).When entering “+++” in dedicated mode,
the modem will switch from “online mode” to “online command mode”.This means that
it is possible to send commands to the local modem.The escape sequence is useful when
disconnecting the active call.The disconnection is made with the ATH command (see the
list of AT-commands below).The ATO command can also be used when in “online com­mand mode”.

\Nn – Select Operating mode

Supported by:

TDW-33 TD-36 TD-36 485 TR-36 TR-36B

Description:

This command controls the preferred error correcting mode for a data connection

Syntax:

AT\N<n>

Parameters:

<n>
0: Selects normal speed buffered mode (disables error-correction mode).
1: Selects direct mode and is equivalent to &M0, &Q0 mode of operation. In this
mode the serial port is directly connected to the data pump, which results in the
lowest possible delay time. This is useful in i.e. the case of polled PLC systems
where the response time is critical.
2: Selects reliable (error-correction) mode. The modem will first attempt a LAPM
connection and then an MNP connection. Failure to make a reliable connection
results in the modem hanging up.
3: Selects auto reliable mode. This operates the same as \N2 except failure to make a
reliable connection results in the modem falling back to the speed buffered normal
mode, \n0.
4: Selects LAPM error-correction mode. Failure to make an LAPM error-correctio
connection results in the modem hanging up. Note: The -K1 command overrides
the \n4 command.
5: Selects MNP error-correction mode. Failure to make an MNP error-correction
connection results in the modem hanging up.

*WCB – Secure access and Callback

Supported by:

TDW-33 TD-36 TD-36 485 TR-36 TR-36B

Description

The secure callback functionality makes the established link more secure. After an incom­ing call the modem will make a callback to either a preconfigured number or to the
incoming number. The callback can be protected by a password. The unit can also be con­figured for a secure access without callback.

If the password is enabled, the calling part will be prompted for the password directly
after connection. When the password is entered correctly, the modem will disconnect
the current link and make a callback after a preset number of seconds WCBTIME.

If the unit is configured with password security, it will allow data only after the password
is correctly entered. After 3 retries of entering wrong password or after 60 seconds, the
link will be disconnected and the callback/secure access aborted.

Numbers and password used by the function is stored in the *wcbtab table
See also AT*WCBTAB.

Syntax:

AT*WCB = <n>
AT*WCB=?
AT*WCB?

Parameters:

<n>
0: Callback disabled (default)
1: Callback enabled, No password needed, callback number only in position 1

in *wcbtab (wcbtab1)
If “*wcbtab1” is empty no callback will be initiated.

2: Callback enabled, No password needed, callback to incoming number

No “RING” message will be sent to the local serial port at that time.
If the Caller ID is present the modem will callback to this number after the time of
WCBTIME.
When the connection is established CONNECT message will be sent to the DTE
interface.
Note that WCID must be enabled and set to the correct format for this function to
operate properly.

6618-3202

3: Access security enabled, Password in one or more positions in WCBTAB<n>

(x = 1 -10). If a correct password is detected the connection is opened without any
callback.
The call request will be accepted silently. No “RING”and “CONNECT” message will
be sent to the local DTE interface at that time.
After a successful connection the answering modem will send the message:
“PASSWORD: “ to the originating side. Enter password and press return.
There will be three attempts given to enter the password correctly.
There is a fixed timeout of 60s to enter the password.
If the entered password is correct the modem will send message “RING” and
“CONNECT” to the DTE interface.

4: Callback enabled, Password and callback number in WCBTAB. The call request will

be accepted silently, no “RING”and “CONNECT” message will be sent to the DTE
interface at that time.
After a successful connection the answering modem will send the message:
“PASSWORD: “ to the originating modem.
When the connection is established the modem will send message “CONNECT”
to the DTE interface.

5: Callback enabled, Password in WCBTAB, callback to incoming number. Except pass-

word is needed the same as n = 2

6: Callback enabled, Password in one or more positions in *wcbtab (x = 1,2 .. 10), call-

back to number that is entered after password check is OK.

Description:

This command is used to program the list of I/O entries with parameters and data.

Syntax:

AT*WIOL = <entry>,<service>,<flag>,<timeout>,<priority>,<”data1”>,<”data2”>,
<data3>, <data4>,<data5>,<data6>

AT*WIOL = ? List all table entries. Listing will present a short form table of the
entire I/O list..

AT*WIOL=n? List all data parameters for a defined entry.

AT*WIOL?

Parameters:

<entry>

I/O entry number, up to 10 entries can be defined.

<service>

I/O entry service
0 = NONE No service defined for this entry
1 = DIAL Makes a connection to the number defined in <data1>
2 = SMS <data1> Destination number of the SMS

<data2> SMS-message.
<data3> SMS service provider number
<data4> SMS protocol type (0 = NONE,1 = UCP,2 = TAP)
<data5> Password if required by provider.

3 = TEXT Make a connection to number defined in <data1> and transfer text

defined in <data2>.
4 = EMAIL Reserved for future use, service not implemented
5 = OUT Make a connection to the number defined in <data1> and set/pulse

the remote output according to pattern defined in string defined in

<data2>. The connection is terminated after the pattern is trans-

ferred.
6 = CMD AT command specified by <data1> is executed when the entry is

trigged
7 = TRANS Makes a connection to number defined by <data1>,

I/O is transferred transparently between the two units. The trans-

parent mode must be ended by a timeout.

46

6618-3202

<flag>

Defines if the establishment of service shall be retried, the time between retries is con­trolled by register S7.

0 = NO No retry, tries once to perform requested action
1 = RETRY Retry infinitely to establish service according to

current table entry.
2 = RETRY_3 Do 1 try and max 3 retries.
3 = NEXT_OK If current service ends with OK the service specified by

next table entry will be trigged.

If fail to perform/establish the current entry service the

unit will return to idle.
4 = NEXT_ERR The unit will execute service specified by next table

entry if fail to perform/establish current service.

If service according to current table entry terminates

normally the unit will return to idle and wait for any

new event trigger.
5 = NEXT_ALLWAYS The next table entry will always be execute regardless

of the exit status of the current.

<timeout>

Timeout is used in Dial and Transparent I/O. The timeout is designed as a inactivity timer
and will be retrigged for each Data / I/O transfer. The timeout is the only normal way to
terminate Dial and Transparent I/O.
Please see Table 1 for reference of state after termination by timeout.
Setting a timeout for any other service than transparent I/O will not cause any failure
but will not have any function.

<timeout> Function of <timeout>

= 0 The service will not be terminated
= 1 – 255 The timeout is specified in units of 10 s.

Valid values 1 – 255 *10 s (10 s – 2550 s)

<priority>

Priority of the service specified.

<priority> Function of <priority>

= 0 An existing connection will not be terminated.

Retries will be made according to setting of <flag>,

time between retries is set by register S7.
= 1 The current connection will be terminated before

the connection specified by service is established.

S38 Delay Before

Hang-Up

– * 20 Definition: S38

Specifies the delay between
the modem receives the
H command (hang-up) to
disconnect and the discon­nect action. Applicable to
error-correction connection
only. Used to ensure that
the modem buffer is sent
before the the modem dis­connects.
For S38 values 0–254 the
modem waits this time until
all data is sent from buffer
before disconnecting.
S38 = 255 the modem does
not time out.
