Modem Features
Power Down Feature
S119 can be set with the number of seconds of no activity before the modem shuts down. The modem will not shut
down if DTR is asserted, if the modem is connected, any key on the keyboard is pressed or an alarm switch is on.
The modem will wake up if:
•
•
•
DTR is raised
there is a Ringing signal or
an alarm switch is asserted.
S119 defaults to 0 (power down disabled).
The modem draws almost no power when powered down.
Dial and Talk Feature
This feature enables a modem to alert, by spoken word, that an alarm situation at a remote site needs attention. The
modems can be configured to dial up to 10 preset numbers and speak a stored message when one of two external
switches are closed.
These switches will connect to pins 12 and 7 (alarm 1) and pins 13 and 7 (alarm2) of the RS232 connector. An
alarm condition is recognised when a short circuit is applied across either pair of pins, eg by use of a relay.
By default to modem will ring stored number 0 if either alarm switch is closed.
To set stored number 0 type:
AT&Z0 = nnnnnnnnnn where nnnnnnnn is the phone number.
You may store up to 10 numbers using &Z0 to &Z9.
The numbers to ring for each alarm can be specified by the AT#ALM command:
AT#ALM1=1,4,8,3
Means than if alarm switch 1 is pressed the modem should ring the stored numbers 1 then 4 then 8 then 3.
AT#ALM2= 9
Means that if alarm switch 2 is pressed dial stored number 9.

Voice Messaging System
This feature can be installed into an MIU56 by downloading a vocabulary file to the modem to enable it to respond
to DTMF tones from a remote modem.
If this feature is enabled by using the #MEM command:
AT#MEM1
AT#MEM2
AT#MEM0
Modem will answer in voice mode after S110 rings if DTR is low
Modem will answer in voice mode after S110 rings regardless of DTR
All voice features off
Dial the modem and wait for it to answer. After the number of rings specified by S110 (default 4) the modem will
answer the call and respond with "Leave a Message after the Beep". If you key in a DTMF digit during the time
this message is played, the message will stop and you can complete entering the PIN number. The factory default
PIN number is 1234. This can be changed by using the new #PIN command.
AT#PINnn…nnn
where nn…nnn is the pin number. Up to 9 digits of PIN number can be specified
If you key in the correct PIN number the modem will say "OK" and ask for a command. You may key in 0 for a
menu of available functions.

Messages 1 and 2 are used by the alarm switches. Other messages can be stored and used as a voice mail box
which can be shared by a group of people who know the PIN number.
If no pin number is entered the user can leave a message after the welcome message beep.
+
To avoid recording a lot of silence the messages can be terminated with the # DTMF key.
About 8 minutes of voice storage in a maximum of 20 individual messages is available.
How to Load the Voice Alarm Messages
If you have not downloaded a vocabulary file use the following procedure:
1.
2.
3.
4.
5.
Connect the modem to a PC running a terminal program (like Hyperterm).
Type ATS119=0 to stop modem going to sleep.
Type AT#MINI and wait for EPROMs to erase. The modem will beep when ready.
Type AT#MEM2 to put the modem into voice answering mode.
Connect modem to phone line and using a touch tone phone dial the modem. The modem will answer
with a brief message "Leave a message after the beep!"
6.
Record your message into the modem for Alarm Condition #1, leaving 2 seconds of silence after the beep
before speaking.

Press the # button on the phone when your message is finished.
Hang up the phone wait a few seconds.
Ring the modem again and record a second message for Alarm #2 following steps 8 and 9. Your
messages are now recorded.
10.
11.
Reconnect modem to a terminal program and type AT#MCD to display the stored messages. The duration
of the 2 messages you have recorded should be visible.
If you wish the modem to answer calls in data mode type AT#MEM0&W in a terminal program to turn
off the voice answering function or AT#MEM1 if you want the voice answering function only when DTR
is low.
To redo the messages, erase the EPROMs using AT#MINI and record the messages again.
Remote Voice Setting of Alarm Messages
If you have installed the vocabulary file, use the procedure detailed in the VOICE MESSAGING SYSTEM to enter
the modem PIN number then use DTMF command *2 the record the first message then enter *2 again to enter the
second message. You may playback the messages immediately by keying DTMF 1 and DTMF 2 to verify that they
sound OK.
Hang up by keying ##.

Operating Modes
Asynchronous Mode
Asynchronous Mode is the normal default mode of the modem. Control and monitoring is performed by executing
the AT commands using a PC fitted with suitable communications software.
Synchronous Operation
Your modem supports two synchronous modes. Mode 1 allows operation with computers which support
asynchronous and synchronous communication on a single RS-232 port. Mode 2 allows your modem to be
operated with dedicated synchronous terminals.
Although your modem can only operate over a single two-wire connection, it will still perform full-duplex
synchronous communication. Half-duplex operation could be simulated by controlling the state of the RTS and
CTS signals.
Terminal Speeds
Your synchronous terminal or host should use the clock signals provided by the modem to synchronise transmit
and receive data. The clock speed will represent the actual connection speed of the modem.
+
When synchronous mode is selected, your modem cannot operate in constant speed mode or use the error
correction or data compression facilities of the modem. Only variable speed mode is available in synchronous
connections (this refers to the modem's terminal speed).
Line Speeds
Your modem supports a number of synchronous line speeds.
When operating in synchronous mode, your modem should always be configured with a locked, non-auto-ranging
B setting (this refers to modem line speed).
For V.34, the B setting only sets the maximum speed. The modem will automatically determine the highest usable
speed for the line.
Synchronous Mode 1
Synchronous mode 1 is selected with the &M1 command.
•
Type: AT&M1 <E>
Your modem will enter synchronous mode whenever it successfully connects to a remote modem.
You should also:
Type: AT&D2 <E>
This allows hang up via your computerÕs DTR signal.
To return to asynchronous operation:
Type: AT&M0 <E>
•
•
Synchronous Mode 2
Synchronous mode 2 is selected with the &M2 command.
•
Type: AT&M2 <E>
Your modem will enter synchronous mode whenever it successfully connects to a remote modem.
You should also:
•
Type: AT&D2 <E>
This allows you to dial and hang up.
When the terminal asserts the DTR signal (DTR makes an OFF-ON transition), your modem will dial stored phone
number zero. The phone number may contain dial modifiers.

Industrial Modem MIU56 User Guide
To return to asynchronous mode:
•
Type: AT&M0 <E>
Your modem will remain in asynchronous mode.
Leased Line Operation
A leased line, or private line, is a telephone line that permanently connects two or more locations. The leased line
does not have any switching equipment associated with it.
Leased-line operation with the modem is selected with the &L command.
If you select leased line operation with the &L1 command, you must issue the ATA command to answer a call, and
the ATD command to initiate a call.
If you use &L2 or &L3 to select Auto leased line operation, you do not need to issue the ATA or ATD commands;
&L2 selects Originate mode automatically and &L3 selects Answer mode automatically. To dial or answer, raise
DTR; to hang up and return to local command state, lower DTR.
+
You will require a special phone cable (available from your dealer) to connect your modem to a leased-
line socket. The phone cable supplied with your modem is suitable for use with normal, dial-up, voice (PSTN)
lines.
Before commencing leased-line communications, it is recommended that a non-auto-ranging B setting be specified.
+
If error correction is required, select a Reliable mode, not an Auto-Reliable mode. (See the \N command.)
Auto-ranging and fallback are disabled in leased-line mode. Your modem will only attempt to connect using the
communications standard specified by the B command and the terminal speed.
Once a connection has been established, if your modem detects a loss of carrier it will continuously attempt to re-
establish the connection.
If the modem is in auto leased-line operation and this configuration has ben stored in memory using the AT&W
command, a timeout period of 10 seconds is available after power up to disable the leased-line mode via the AT&O
command. Alternatively, this command can be sent with DTR low.

Distinctive Ring
The Industrial Modem is able to discriminate between three different types of rings. This is useful if you purchase
the dual line service. With dual line service, two phone numbers are shared for one telephone line. One number
can be used for Voice and the other number can be used for your Modem. To enable the modem to answer only
when your modem number is dialled, issue the command: AT-SDR=4 S0=2&W.
AT-SDR=n,x
where n=0 to 7, default=0,
x=0 Disable Distinctive Ring response suffix;
x=1 Enable Distinctive Ring response suffix (default)
Any ring detected and reported as "RING"

Use AT-SDR=4 for dual line service. Do not set Auto Answer below 2 when Distinctive Ring is
enabled.
