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.

… Frequently used settings for PLC-systems PSTN Network 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.
… TDW-33 – Secure Call-back 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.

… TDW-33 – Silent answering on predefined number 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.
