Introduction

The Westermo ID-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 in 2 or 4 wire connections. Terminal data rates of up to 115.2 kbit/sec can be handled with a 128 kbit/s ISDN B-channel bit rate. The ID-90 has been designed to meet the European ISDN standard DSS1 as well as French VN4. All standard ISDN transport protocols are supported including HDLC transparent, X75, PPP and ML-PPP. V.110 asyncronous is supported with flow control at data rates up to 19.2 kbit/sec.

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 ID-90 is available in two standard versions: One for high input voltages, version HV with nominal voltage range 95–240V AC and 110–240V DC ±10%. One low voltage version, version LV with nominal input voltages 12–45V AC and 12–55V DC ±10%.

The ID-90 has 4 Alarm inputs that can be used to trigger 20 character SMS paging messages or establish automatic data connections, making the unit ideal for alarm monitoring and remote diagnostics. The ID-90 features DIP-switch configuration and can be programmed using AT-commands, and a Configurator for local as well as remote configuration and CAPI 2.0 compatibility.

The ID-90 is also available in an optional configuration with an internal analogue V90 modem enabling connections from ISDN to analogue modem end locations.

The ID-90 has been designed with the engineer in mind, hence the extensive information on the command set, S registers, DIP-switches and error codes. We have endeavoured to include all necessary information however if you need more please do not hesitate to call us.

Safety

This equipment should only be installed by professional service personnel. If the unit is intended for permanent connection to mains supply, there should be a readily accessible disconnect device (circuit breaker) incorporated into the fixed wiring. The ID-90 ISDN S0 is compliant to the requirement for TNV1 circuits for connection to Telecommunication networks. The mains connection is classified as hazardous voltage and the ID-90 classified as a Class I equipment. The supply voltage to the Alarm input must use a SELV classified voltage source. The RS-232/V.24 and RS-485 interface must only be connected to SELV circuits. Description of the above classifications are given in SS-EN 60950 Issue 5. The mains input is protected with a 1A, 250V time lag fuse. The fuse must only be replaced with the same type and rating. Wickman type no: 19372 1A/250V or Littelfuse

Installation

The Terminal Adapter should be connected in the following way: Power connection is made through screw-block at bottom right corner. For HV-version a 3-pole connector, and for LV-version a 2-pole connector is used.

Computers or other equipment are connected through an RS-232/V.24 or RS-485 connection. The RS-232/V.24 uses a 9-pole D-sub and the RS-485 a 9-pole screw connector. Do not use ribbon cable for RS-232/V.24 connections.

Typical S0-bus connections

The Terminal equipment TE/TA like the ID-90 Terminal adapter can be connected to the NT in 3 different ways always with a terminating resistor TR in each end of the bus, TR should in all three cases be 100 ohm:

• Point to Point. In this configuration the ID-90 is the only TA on the S0bus. A distance d1 of 1000 m is generally archived with a 0.3 mm

40 nF/km cable.

• Short Passive Bus. The short passive bus puts no restriction on the distance between units, but only specifying the maximum round trip delay to be 10 to 14 µs giving a d1 of 100 to 200 m depending on the cable impedance. Up to 8 ID-90 in combination with other terminal equipment can be connected to the S0bus with a maximum connection length d2 = 10 m.

• Extended Passive Bus. The difference between the short passive bus and the extended passive bus is that the extended passive bus specifies a distance between the units, d3 and that the units are located at the far end from the NT at a distance of d3 from the far end terminating resistor TR. The range of d3 is from 25 to 50 m giving at least d1 =500 m. (d2 see Short Passive Bus).

Alarm inputs

The four alarm inputs are accessed through screw terminals, the alarm inputs are opto-isolated from all other parts of the ID-90. The alarm inputs need an external supply voltage of 10–60V DC to be operated. The supply is connected between the alarm input common and the four inputs via making or breaking contacts. The inputs is not polarity sensitive but all inputs must use the same common. The alarm inputs can use any mix of making and breaking contacts as the alarm trigger condition is programmable through AT-commands.

Example 1

Alarm through relay contacts.

Example 2

Alarm from a PLC with open collector.

AT command set

All parameter can be changed by using an extended AT command set described in this chapter.

Please check if the factory setting will fit with your environment. The factory setting is

described (highlighted) in the parameter list shown in chapter “AT command set” (see below).

If you want another configuration as set in the factory default setting, please do the following steps:

• Connect the ID-90 to ISDN interface

• Connect the PC’s com-port to the DTE interface of the ID-90.

• Connect the power supply to the mains socket.

• Start a terminal emulation on your PC, please verify that the baudrate setting of the terminal emulation fits those of the ID-90.

• Set up the parameter of the ID-90 from the terminal emulation and save the parameter using the AT command set.

Example: To change the used B channel protocol to X.75 please enter the following commands:

ATB10<↵> (set protocol to X.75) AT&W<↵> (save the new configuration)

• Leave your terminal emulation and start your application program.

With the exception of the command A/ (Repeat command) all commands begin with the prefix AT and AT!, where the prefix AT! is used to identify commands to the analogue V90 option. Commands are terminated with <CR>. Corrections in a command line are done with <BACKSPACE>. A command line has a maximum of 80 characters. The command line is automatically cancelled by longer input. Blanks are ignored, capital/small letters are not significant.

The parameter settings of the ID-90 obtained when using the AT commands can be permanently stored (AT&W) and are not lost by resetting or by leaving the AT command mode.

To enter the AT command mode during an active data connection you must use the following sequence (“Escape sequence”):

at least 1 sec pause <+><+><+> 1 sec pause

The time gap between all three plus signs may not exceed 1 sec. The escape sequence is transmitted transparent to the remote device.

A/ – Repeat last command line

This command repeats the commands of the last entered command line.

Note: No prefix AT is required.

##An – Only analogue outgoing call (only ID-90V90)

Can enable the adapter to make analogue calls even if no control character (’#’ or ’!’) is used in the dial string. This also implies that no digital outgoing call can be made when AT##A1 is set. Digital incoming calls can still be received.

AT##A0: configures the adapter to be able to make both analogue and digital

outgoing calls. (default)

AT##A1: configures the adapter only to make analogue outgoing calls.

A – Accept incoming call

Using this command you can accept an incoming call, if automatic call acceptance is not set (Register S0 = 0). An incoming call is displayed by the message “RING” or the code “2”. Must be the last command in an AT command line.

ATA[//<UUS1data>] UUS1data transmitted data with UUS1 signalling

B – B channel protocol

Transmission protocol for data communication in the B channel.

ATB0: V.110 asynchronous (For file and data transfer i.e.

for BBS access)

ATB3: HDLC async to sync (Async PPP to sync PPP, single link

conversion i.e. for Internet / PPP dial-up network access) ATB4: HDLC transparent (octets are packed into HDLC frames) ATB5: Byte transparent (raw B channel data) ATB10: X.75- SLP (For file and data transfer i.e. for BBS

access, default)

ATB13: V.120 For file and data transfer

i.e.AOL/CompuServe access

ATB20: X.31 B channel (X.25 B channel, access to X.25 packet

switched network over B-channel)

ATB21: X.31 D channel (X.25 D channel , access to X25 packet

switched network over D-channel

ATB22: T.70-NL-CEPT (For telematic services over ISDN i.e. T-

Online videotex access) ATB23: T.90-NL For telematic services over ISDN ATB31: ML-PPP (ML-PPP, Async to sync PPP conversion in

Multilink PPP mode, for internet access)

%B – Set local baudrate

Sets the local baudrate of the ID-90 to the desired value (fix value) or to autodetection. When autodetection is set, the ID-90 will recognize the desired baudrate with every newly entered AT command by the terminal equipment (PC). With all other settings the PC must use the same baudrate. Must be the last command in an AT command line.

AT%B0 Automatic local baudrate detection enabled (autobauding, default) AT%B1 Local baudrate set to 1 200 bit/s AT%B2 Local baudrate set to 2 400 bit/s AT%B3 Local baudrate set to 4 800 bit/s AT%B4 Local baudrate set to 9 600 bit/s AT%B5 Local baudrate set to 19 200 bit/s AT%B6 Local baudrate set to 38 400 bit/s AT%B7 Local baudrate set to 57 600 bit/s AT%B8 Local baudrate set to 115 200 bit/s

Note: Autobauding (AT%B = 0) is available for AT command set only. If autobauding is

set and cmds is changed to PAD, br will be set to 4 (9 600 bit/s).

CONF – Enter TA+Configurator

Enters directly into the TA+Configurator, the configuration prompt “#” will be displayed. Leave the TA+Configurator with the command “quit”.

ATCONF

&C – DCD control

Selects the behaviour of the DCD control line from the ID-90.

AT&C0 ID-90 control line DCD is always ON AT&C1 DCD ON indicates ISDN connection is established

and synchronised (default) AT&C2 DCD follows DTR AT&C3 DCD indicates link level established (X.31-D only)

#C – Received bearer service

Shows the bearer service that is received with an incoming call in hexadecimal coding hbhb. The value for hbhb (word) is the CIP value as defined in the CAPI 2.0 specification.

AT#C

#C1=hbhb – Select bearer service outgoing

Selects the bearer service that will be sent with an outgoing call The value for hbhb (word) is the CIP value as defined in the CAPI 2.0 specification (default 0002).

Example: an outgoing call as a voice call: AT#C1=0004.

24 6607-2204

#C2=hbhbhbhb – Select bearer service incoming

Selects the bearer services that can be accepted with an incoming call. The definition of hbhbhbhb (double word) is the CIP mask as defined in the CAPI 2.0 specification (default 00010016).

Example: AT#C2=00010016: Accept analogue incoming calls

AT#C2=00000001: Accept all incoming calls.

Note: Before issuing an outgoing call the command AT#C1 has to be set.

To use the predefined services please setup factory defaults (AT&F).

!%C – Enable/Disable Data Compression

Enables or disables data compression negotiation. The modem can only perform data compression on an error corrected link. The parameter value, if valid, is written to S41 bits 0 and 1.

AT!%C<value>

0 Disables data compression. Resets S46 bit 1. 1 Enables MNP 5 data compression negotiation. Resets S46 bit 1. 2 Enables V.42 bis data compression. Sets S46 bit 1. 3 Enables both V.42 bis and MNP 5 data compression. Sets S46 bit 1. (default)

256607-2204

D – Initiate outgoing call

Dials the number (D for Dial). The dial modifier “W", “>”, “T”, “;”, “@” can be freely inserted in the dial string; they have no influence on the dial procedure of the ID-90. Must be the last command in AT command line. Any character input while the ID-90 is dialing will cancel the dialing procedure.

ATD<CALLEDnumber>[/<subaddr>][//<UUS1data>]

CALLEDnumber: Call number for a dialed connection to an analogue PSTN number

over ISDN using the internal analogue modem AT!DL Dial the last dialed number AT!DS=n Dial number n from stored telephone number list (n = 1..3)

(See command AT&Z to store numbers) and catab n

Notes: – To setup the own subaddress see configuration command sub.

– Adding an “e” to CALLEDnumber indicates that a connection to the internal

remote access of a ID-90 shall be performed, the protocol X.75 (ATB10) has to be used.

26 6607-2204

&D – DTR control

Selects the behaviour of the ID-90, when the DTE control line DTR changes from ON to OFF.

AT&D0 DTR is evaluated: ignored AT&D2 DTR is evaluated: dropping the DTR line by the DTE will disconnect

an existing ISDN connection. An incoming call will accepted only with DTR active. (default)

AT&D4 DTR is evaluated: Incoming calls will be accepted independent of

DTR status; DTR drop disconnects an active connection

!+DS – Data Compression

This extended-format compound parameter controls the V.42bis data compression function if provided in the modem. It accepts four numeric subparameters:

AT!+DS=[<direction>[,<compr_neg>[,<max_dict>[,<max_string>]]]]

<direction> Specifies the desired direction(s) of operation of the data compres-

sion function; from the DTE point of view. 0 Negotiated; no compression (V.42bis P0=0). 3 both directions, accept any direction (V.42bis P0=11). (default)

<compr_neg> Specifies whether or not the modem should continue to operate if the

desired result is not obtained. 0 Do not disconnect if V.42bis is not negotiated by the remote

modem as specified in <direction>

<max_dict> Specifies the maximum number of dictionary entries (2 048 entries)

which should be negotiated (may be used by the DTE to limit the codeword size transmitted, based on its knowledge of the nature of the data to be transmitted).

<max_string> Specifies the maximum string length (32 bytes) to be negotiated

(V.42bis P2).

Reporting Current or Selected Values

E – Local echo

Selects the local echo in command mode.

ATE0 No local echo ATE1 Local echo on in command phase (default)

!%E – Enable/Disable Line Quality Monitor

and Auto-Retrain or Fallback/Fall Forward

Controls whether or not the modem will automatically monitor the line quality and request a retrain (%E1) or fall back when line quality is insufficient or fall forward when line quality is sufficient (%E2). The parameter value, if valid, is written to S41 bits 2 and 6. If enabled, the modem attempts to retrain for a maximum of 30 seconds.

AT!%E0 Disable line quality monitor and auto-retrain. AT!%E1 Enable line quality monitor and auto-retrain.

AT!%E2 Enable line quality monitor and fallback/fall forward.

Fallback/Fall Forward. When %E2 is active, the modem monitors the line quality

(EQM). When line quality is insufficient, the modem will initiate a rate renegotiation to a lower speed within the V.34/V.32 bis/V.32 modulation speeds. The modem will keep falling back within the current modulation if necessary until the speed reaches 2 400 bit/s (V.34) or 4 800 bit/s (V.32). Below this rate, the modem will only do retrains if EQM thresholds are exceeded. If the EQM is sufficient for at least one minute, the modem will initiate a rate renegotiation to a higher speed within the current modulation speeds. The rate renegotiations will be done without a retrain if a V.32 bis connection is established. Speeds attempted during fallback/fall forward are those shown to be available in the rate sequences exchanged during the initial connection. Fallback/fall forward is available in error correction and normal modes, but not in direct mode.

!+ES – Error Control

This extended-format command specifies the initial requested mode of operation when the modem is operating as the originator, optionally specifies the acceptable fallback mode of operation when the modem is operating as the originator, and optionally specifies the acceptable fallback mode of operation when the modem is operating as the answerer. It accepts three numeric subparameters:

AT!+ES=[<orig_rqst>[,<orig_fbk>[,<ans_fbk>]]]

<orig_rqst> Decimal number which specifies the initial requested mode of

operation when the modem is operating as the originator. The

options are: 0 Not supported. 1 Initiate call with Normal Mode (also referred to as Buffered Mode)

only. 2 Initiate V.42 without Detection Phase. If V.8 is in use, disable

V.42 Detection Phase. 3 Initiate V.42 with Detection Phase. (default) 4 Initiate MNP. 6 Not supported. 7 Initiate Frame Tunneling Mode when connection is complete,

and Data Mode is entered.

<orig_fbk> Decimal number which specifies the acceptable fallback mode of

operation when the modem is operating as the originator. 0 LAPM, MNP, or Normal Mode error control optional. (default) 1 Not supported. 2 LAPM or MNP error control required; disconnect if error control

is not established. 3 LAPM error control required; disconnect if error control is not

established. 4 MNP error control required; disconnect if error control is not

established.

<ans_fbk> Decimal number which specifies the acceptable fallback mode of

operation when the modem is operating as the answerer or specifies V.80 Synchronous Access Mode. 0 Not supported. 1 Error control disabled, use Normal Mode. 2 LAPM, MNP, or Normal Mode error control optional. (default) 3 LAPM, MNP, or Direct Mode error control optional. 4 LAPM or MNP error control required; disconnect if error control

is not established. 5 LAPM error control required; disconnect if error control is not

established.
