Description
The Westermo IDW-90 is an industrialised ISDN Terminal adapter. This Terminal adapter
has been developed with high speed industrial data communications in mind and has
some features you would not expect to find on normal adapters.
The unit is DIN rail mounted and has both an RS-232/V.24 and RS-485 interface sup-
porting both 2 and 4 wire connections.
Terminal data rates of up to 230 kbit/sec can be handled with a 128 kbit/s ISDN B-chan-
nel bit rate.
The IDW-90 has been designed to meet the European ISDN standard DSS1. All stand-
ard ISDN transport protocols are supported including HDLC transparent, V.110 asyn-
chronous, X75, PPP and ML-PPP.
In the IDW-90 has a also an analogue V.34 modem been included allowing communica-
tion with analogue modems over the ISDN. The IDW-90 can be configured to automati-
cally select if analogue modem shall be used to reach the called location.
The combination of analogue and ISDN modem and V.110 protocol support makes the
IDW 90 especially suited for mixed environments there an ISDN connected modem shall
be reached from ISDN, analogue and GSM networks .
A watchdog facility continually monitors the power supply and internal hardware as well as
the operational software. In the event of a problem the modem automatically resets. This
feature has been included to make the unit more suitable for use in unmanned locations.
The modem also has password protection, dial-back security and caller ID answering to
ensure that only authorised users can communicate with the modem and any connected
equipment.
The IDW-90 also has a single digital input and output relay. The input and output can
be used to trigger, or be triggered by a number of different user defined events. Both the
digital input and output are galvanically isolated from the rest of the modem.
For ease of setup the modem is supported by the Westermo IDW-tool configuration
software but also has DIP switches to assist configuration. Drivers for Windows setup
are also supplied.

Functional description
Remote configuration
The IDW-90 can be configured from a remote modem. To configure a IDW-90 any GSM ,
ISDN or PSTN modem can be used.
The modem used to configure is referred as “local modem”. Enable remote config by
setting DIP switch 4:7.
Please make sure that the remote IDW-90 is connected to the ISDN network and is
powered up.
… Connect the local modem to it’s media (ISDN, PSTN or GSM)
… Connect the PC’s com-port to the DTE interface of the local modem.
… Connect the power supply.
… Start a terminal emulation program (i.e. Windows Hyper-Terminal)
… Configure the local modem protocol
1. If local modem is a GDW-11/12 a normal GSM data connection should be used.
2. If local connection is ISDN, configure with the B channel protocol V110 9600 bit/s
3. If local connection uses some analogue modem, the modem has to be configured for
V32 modulation line speed 9600 bit/s.
… Set up a connection to the remote IDW-90 to be configured by using the normal
dial command: ATD<No><CR>. When connected send the remote escape sequence
<++++>. The called remote IDW-90 shall acknowledges by requesting the remote
password. Please enter the correct password (default: no password, just return). Now
you can configure the remote IDW-90 using AT-commands. Password for remote con-
figuration is defined with AT*WRAP – Remote access password.
… Configure the parameter on the remote IDW-90 from your terminal program and
save the settings with AT&W.
Hang up the connection using the ATH command.

Generic I/O
The generic I/O gives the following functionality:
1. Establishing a data connection to a predefined target number
When the input is switched (pulsed), the modem establish a data connection to
the stored predefined number. After a time, specified in the modem, without data
exchange, the connection is released (inactivity timer).
2. Sending a SMS Message to a predefined targetnumber
When the input is switched (pulsed), the modem shall establish a connection to a SMS
service centre defined by a predefined number. The SMS Messages can handle at least
160 characters. TAP and UCP protocols are supported.
3. Sending a Text Message to a predefined targetnumber
When the input is triggered, the modem will establish a connection to the stored tel-
ephone number and transfer a predefined text message.
4. Switch the remote digital output
When the input is triggered, the modem will establish a connection to the stored
number of an remote unit and send out a command, that switches (pulses) the remote
output according to a predefined sequence.
5. Execute AT-Command string
Execute a pre-programmable AT command string stored in the table of entries.
This can for example be used for switching DTE communication parameters for
online an offline mode by using two entries.
6. Transparent I/O
When the input is triggered, the modem will establish a connection to the stored
number of an remote unit and send out a command, after a connection is established,
the I/O is bi-directional.
To accept any remote generic I/O on a modem the “Remote I/O Enable” DIP switch
must be set “ON”
Digital Output
The digital output gives the following functionality:
1. Output Contact
The modem has an change over relay output (SPDT-contact). The output can be
controlled by a remote modem through Transparent I/O and Output service in the
Generic I/O function. The output can also be programmed to follow the local DCD or
DTR signals.
2. Remote controlled
The output can be programmed to follow a remote modem data input. A remote unit
can also set/reset the output as well as transferring a sequence of set- and resets of
the output.
3. Follow DCD/Network
The output can be programmable to follow the local DCD or DTR signal.
