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 supporting 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-channel bit rate.
The IDW-90 has been designed to meet the European ISDN standard DSS1. All standard ISDN transport protocols are supported including HDLC transparent, V.110 asynchronous, X75, PPP and ML-PPP.
In the IDW-90 has a also an analogue V.34 modem been included allowing communication with analogue modems over the ISDN. The IDW-90 can be configured to automatically 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.

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 configuration 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 telephone 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.

Digital Input
The digital input gives the following functionality:
1.
Static input
A static digital level trigged input high or low triggers the Generic I/O. With a level trigged input only the first entry in the Generic I/O list can be trigged by the I/O input.
The input is trigged when the selected level has been stable for ta ms.
A new trig will not occur until the input has return to the opposite state an back again.

Before DIP-switch settings:
Prevent damage to internal electronics from electrostatic discharges (ESD) by discharging your body to a grounding point (e.g. use of wrist strap)
NOTE
DIP-switch alterations are only effective after a power on or commands
“AT**loadsw” and “AT**reset”.
A setting configured by any other method during normal operation, overrides the DIP-switch setting. However, at power up, the DIP-switch settings have precedence over the setting configured by any other method.

Termination recommendations
The RS-422/485 line must be terminated. In the TD-36 485, the termination is combined with fail-safe functionality.The termination is used to prevent undefined states when the bus is in tri-state condition.
… Using 2-wire RS-485 both ends should be terminated.
… Using 4-wire RS-485 both pairs shall be terminated at both ends.
… Using 4-wire RS-422 it’s only necessary to terminate the receivers.
RS-422/485 connection pins can be differently named. For some equipment brands the T+ corresponds to A, but other brands might use some other naming convention.
If a unit does not work it can help to swap A and B.

… Frequently used settings for PLC-systems
ISDN
Network
Most PLC-systems and other industrial applications where modems are used, require the same changes to default settings.
The most commonly encountered problems concern speed, parity and control signals from the connected equipment.
Speed and parity are changed with the switches under the cover in block S1. If this action does not solve the problem the modem’s answering codes and possible echoing of commands might be the source of the difficulty.
Below follows a list of commands that might resolve the problems. The commands may of course be placed on one single command line if desired.
