Description
The TDW-33 is designed to function reliably within industrial environments and in areas of high level interference. The modem has an RS-232 interface supporting terminal data rates up to 115 kbit/s.
The TDW-33 is a V.90 modem meaning that it can support data rates of up to 56 kbit/s on the PSTN line side.
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 TDW-33 is ideal for industrial applications as it mounts easily on to a 35 mm
DIN-rail, runs from 12–36 VDC power supplies, has screw terminal connections and is tri galvanically isolated.
For ease of setup the modem is supported by the Westermo TD-tool configuration software. Drivers for Windows setup are also supplied.
… Extended temperature range –25°C to +70°C
… Data rate up to 56 kbit/s (V.90)
… Terminal rate up to 115.2 kbit/s
… DTR and incoming data dialling
… Watchdog
… Secure call back and access

Remote configuration
The TDW-33 can be configured from a remote modem. To configure a TDW-33 any GSM,
ISDN or PSTN modem can be used.
The modem used to configure is referred as the “local modem”. To enable remote configuration use the command AT*WRAA.
Please make sure that the remote TDW-33 is connected to the PSTN network and is powered up.

9600 bit/s ured for V32 modulation and a line speed of 9600 bit/s.
mal dial command: ATD<No><CR>. When connected send the remote escape sequence <++++>. The called remote TDW-33 will acknowledges by requesting the remote password. Enter the correct password (default: no password, just return). Next configure the remote TDW-33 using AT-commands. The password for remote configuration is defined with AT*WRAP – Remote access password and save the settings with AT&W.

* To minimise the risk of interference, a shielded cable is recommended when the cable is located inside 3 m boundary to the rails and connected to this port. The cable shield should be properly connected (360°) to an earthing point within 1 m from 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.

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 in the TDW-33.
Please refer to TD-Tool for a complete description of the functionality of the
Windows program.
Configuration
The TDW-33 can be configured both from the local DTE interface and remotely over the

Connect the DSR signal via a relay, or other potential free contact, to the DTR signal.

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.
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.

The TDW-33 is connected to a PLC which one want to restrict access to. The TDW-33 can support access control through the Secure Callback function. In this example password and callback to a predefined number is chosen. The modem in the calling end is here chosen to be a PSTN modem, but can be any of the PSTN, ISDN or GSM modem from the Westermo product range.
The DTE serial speed between the PLC – TDW-33 and TD-36 – PC is assumed to be

The TDW-33 is connected to a power meter which is remotely monitored. The TDW-33 shares the PSTN line with normal telephones which is preferred not to give a ring signal when the meter is read.
The TDW-33 is configured to answer calls on the Caller ID received, the valid numbers to answer is programmed into the TDW-33. There exists a number of standards for sending Caller ID check which standard is used by your operator. The TDW-33 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.
The modem in the calling end is here chosen to be a PSTN modem, but can be any of the PSTN, ISDN or GSM modem from Westermo product range.
