Description

The TD-36 (485) is designed to function reliably within industrial environments and in areas of high level interference.

The TD-36 (485) is a V.34 modem meaning that it can support bidirectional data rates of up to 33.6 kbit/s on the PSTN or leased line side. Fast connect ensures that leased lines can re-establish connections in the range of 5 seconds.

The modem is equipped with transient protection on the line side and a “watchdog” that monitors and automatically resets the modem in the event of a fault. These functions together with remote configuration make the modem perfect for installation at unmanned sites and prevent the need of costly service trips.

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 TD-36 (485) 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 TD-tool configuration software but also has DIP switches to assist configuration. Drivers for Windows setup are also supplied.

… Dial backup for PSTN and Leased Line (only in TD-36 485)

6618-2202

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 pulsed, the modem establishes a data connection to the stored predefined number. After a time (specified in the modem) without data exchange, the connection is released by an inactivity timer.

2. Sending an SMS Message to a predefined targetnumber

When the input is pulsed, the modem will send an SMS to 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 modem number and transfer a predefined text message. This is not an SMS message.

4. Using the remote digital output

When the input is triggered, the modem will establish a connection to the stored number of a remote TD-36 and send out a command, that pulses the remote output according to a predefined sequence.

5. Executing an AT-Command string

Pre-programmed AT command strings stored in the modem can be executed.

These can (for example) be used for switching DTE communication parameters for online and offline modes by using two entries.

6. Transparent I/O

When the input is triggered, the modem will establish a connection to the stored number of a remote TD-36 and send out a command, and after a connection is established, the I/O is bi-directional.

6618-2202

Digital Output

The digital output gives the following functionality:

1. Output Contact

The modem has a change over relay output (SPDT-contact). This 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. Remotely 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.

≥t a t a

Trig

Low level trigged input timing t a

≥t a

<t a

Trig

No trig due to low level shorter than t a

6618-2202

2. Pulsed Input

When input is set to edge trigged pulsed the number of pulses counted selects the entry to be trigged.

For the pulsing of an input, some timings must be kept.

The input is filtered and pulses shorter than ta is discriminated. The time between pulses must also be kept shorter than Tp. One other restriction on Tp is that Tp ≥ 2ta.

When time between pulses exceeds Tp the number of pulses are accumulated and an entry selected by number of pulses counted.

The parameter ta is also used when output pulsing is selected.

The parameters ta and Tp are programmable from 10 ms to 2550 ms.

For a cable located within 3 m and connected to this port, the use of shielded cable is recommended, this is to minimise the risk of interference. The cable shield should be properly connected (360°) to an earthing point within 1 m of this port. This earthing point should have a low impedance connection to the conductive enclosure of the apparatus cabinet, or similar, where the unit is built-in. This conductive enclosure should be connected to the earthing system of an installation and may be directly connected to the protective earth.

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.

Windows configuration tool TD-Tool

The TD-Tool is a PC – application program with a graphical interface for easy configuration of the complex functions found on the encolsed CD or at the Westermo website.

Please refer to TD-Tool for a complete description of the functionality of the Windows program.

AT-Commands

Please refer to the AT Commands Interface Guide found on the enclosed CD or at the Westermo website for a complete list of all available AT-commands and a detailed description of the serial AT-command interface.

Configuration

The TD-36 (485) can be configured both from the local DTE interface and remotely over the PSTN network. Whether the local or remote interface is used the configuration can be made with AT-commands or with a PC-based application configuration tool. Basic configurations can also be made with DIP switches locally.Remote configuration

The TD-36 (485) can be configured from a remote modem. To configure a TD-36 (485) any GSM, ISDN or PSTN modem can be used.

The modem used to configure is referred as the “local modem”.

Please make sure that the remote TD-36 (485) is connected to the PSTN 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 data rate and word format.

… Set up a connection to the remote TD-36 (485) to be configured by using the normal dial command: ATD<No><CR>. When connected send the remote escape sequence <++++>. The called remote TD-36 (485) will acknowledges by requesting the remote password. Enter the correct password (default: no password, just return). Next; configure the remote TD-36 (485) using AT-commands. The password for remote configuration is defined with AT*WRCP – Remote configuration password.

… Configure the parameter on the remote TD-36 (485) from your terminal program and save the settings with AT&W.

… Hang up the connection using the ATH command.

Most PLC-systems and other industrial applications where modems are used require the same changes to the standard 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.

… Leased Line connection using 2- or 4-wire

Leased Line

Leased Line connections can be set up using 2-wire (or 4-wire in TD-36 485).

When renting a 4-wire line from a telephone company one pair of cables for transmission and one pair for reception are usually provided.

The maximum transmission distance depends on the attenuation of the line.

The maximum value is theoretically 30 dBm. To have a good error rate it is recommended to keep the attenuation under 25 dB. When renting lines from a telephone company a longer transmission distance is normally possible as the signals are probably transmitted over PCM-lines, i.e.

fibre optic or other media with low attenuation.

To set the modem for leased line applications use the dip switches.

The TD-36 is connected to a power meter which is remotely monitored. The TD-36 shares the PSTN line with normal telephones which is preferred not to give a ring signal when the meter is read.

The TD-36 is configured to answer calls on the Caller ID received, the valid numbers to answer is programmed into the TD-36. There exists a number of standards for sending

Caller ID check which standard is used by your operator. The TD-36 supports the major implementations of Caller ID. In this example the DTMF Caller ID version is used.

Note that some implementations doesn’t give the possibility to make a silent answer since the Caller ID is sent between first and second ring signal.

In this application the TD-36 485 I/O is used to send a SMS and then make an transparent I/O connection. The transparent I/O is in this example set up to an IDW-90 ISDN modem, but can be any of the Westermo remote product supporting Generic I/O

(IDW-90, TD-36 485 and GDW-12).

The TD-36 485 has a alarm signal connected to it’s I/O input, when this input is activated by the external alarm contact an SMS defined by Entry 1 in the entry list is sent. When the SMS is transferred Entry 2 is programmed to be trigged. Entry 2 is programmed to set up an Transparent I/O connection to an ISDN-modem IDW-90. The status of the alarm signal will be transferred to the remote IDW-90 and activate an Alarm bell.

At this time the SMS should be available on the operators mobile showing the reason for the alarm. The operator can acknowledge the alarm, the acknowledge signal will now be transferred back to the originating TD-36 485 and alarm system. The alarm system will deactivate the alarm output causing the remote alarm bell to stop sounding.

The Transparent I/O connection will be terminated by a programmed timeout.
