MTL01 Generality
1. GENERALITY
Congratulations for choosing Digicom MTL01.
MTL01 is an analog modem projected to be integrated into
professional equipments and to be used for data transfer with
remote devices.
It is possible to configure MTL01 using a completeAT commands
set.
To guarantee the maximum compatibility with the industrial
systems, MTL01 has been carried out with an ISA-Bus interface,
which is very popular in these environments.
ISA-Busslots are supported bythe most Operating Systems,even
by the less recent ones (eg. MSDOS).

Quick Guide
2.1
MTL01 Installation
2. INSTALLATION
Before inserting an ISA-Bus modem into the terminal, a COM serial port and an interrupt must be set
through the dip-switches and/or jumpers on the card. The Terminal will be able to interface the modem
using the COM and IRQ resources.
The same concept is used also for Terminals with Operating System: in this case MTL01 is detected as a
serial port; this means that, during the installation it is important to detect the new COM port.
After the installation, you can configure the modem using AT commands or a Windows“ driver (Standard
Modem).
For the hardware installation, please follow this procedure:
Remove the modem from its package, and check it is OK.
Set the dip-switch with COM port and IRQ (see table below).
Switch-OFF the Terminal, then insert the modem in a free ISA-Bus slot.
Fix the card modem and close the Terminal.
Insert the phone line cable using the one supplied in the package.
Oncethe installation oftheserial port isover,youcan start with themodem configuration usingATcommands.
2.1. INSTALLATION - WINDOWS®
Windows® sees MTL01 as a serial port, so you must look for a free COM and IRQ in the Operating System,
then set a COM and IRQ in MTL01.
Selectthe System utilityin the Control panel,thenselect the Hardware folder and click the Device manager
button. In the most recent Operating Systems use the System Information utility present in Programs/
Accessories/System Utility.
Now set the dip-switch and the jumper on the modem card.
If there are not free COM or IRQ, you can disable COM1 or
COM2 (if it is not used) in BIOS.
For the hardware installation, please follow this procedure:
Remove the modem from its package, and check it is
OK.
Set COM and IRQ by the dip-switch (see table below).
Switch-OFFthe PC, then insert the modem in a free ISA-
Bus slot.
Fix the card modem, and close the PC.
Insert the phone line cord supplied in the modem
package.
Run Windows®: MTL01 could not automatically detect the
new serial port as it is not a Plug&Play (PnP) card. Run the
Add/Remove Hardware utility in the Control Panel and
select automatic search: Windows® will detect a new serial port.
Afterthe serial portinstallation is over, you canconfigure the modemusingATcommands,or with aWindows®
driver (Standard Modem).

3.1
MTL01 Modem AT Command Set
3. MODEM AT COMMAND SET
The modem supports a completeAT commands set to define the configuration, initiate or terminate modem
communication, test the modem and the communication link. The modem will work in two basic operations:
command mode and data mode.
COMMAND mode is when the modem is not connected to another modem, therefore “Off Line” or in a idle
condition. In this mode the modem will accept commands beginning withAT prefix. DATA mode is when the
modem is connected to another modem, that is an “On Line” condition or functioning. In this mode all the
characters sent from computer are interpreted as data and they are sent to the remote modem. You may
switch from data to command mode by entering an escape sequence. The default escape sequence is +++.
To be valid, the sequence must be followed by an AT command, i.e. "+++AT<CR>".
Data Length
Digicom's modems can manage the following ASCII code formats:
CASE START BIT DATA BIT PARITY STOP BIT TOT
11 7 1 110
21 8 0 110
31 7 0 210
The modem will accept even, odd, mark, or space.
3.1. AT COMMAND SET DESCRIPTION
NOTE:
""
default factory commands
AT Attention
All the characters following the letters ‘AT’are commands. InAT command mode the modem automatically
detects the computer speed and parity format. The modem will response using the same speed and parity
format of AT command.
ATA Answer incoming data call
Cause the modem to go off hook and attempt a handshake in answer mode.
A/ Repeat last command
Cause the modem to repeat the lastAT command.This command must not be preceded byATand followed
by CR.
ATD Dial Command
0:9 Dial numbers
*DTMF digits
#DTMF digits
A..D DTMF digits
PPulse dial
TTone dial
S=n Select a number stored in the modem internal book (see AT&Z command)
!Flash
WWait for dial tone
@Wait for five seconds of silence
,Pause
LRecall the last number dialed
;Return to Command state. Added to the end of the dial string, this causes the modem to return
to the command state after it processes the portion of the dial string preceding the “;”. The
modem will enter call progress only after an additional dial command is issued without the “;”
terminator.
