Overview of Westermo TDW-33 Modem
The TDW-33 is a simple industrial modem designed to allow cost-effective and simple remote access to legacy serial
industrial equipment. The AT command-driven modem is capable of synchronising with a wide range of traditional modem
negotiation standards, providing data rates up to 56.7 kbit/s. Designed with remote unmanned industrial locations in mind, the modem can operate in extremes of temperature and
electromagnetic fields. The complete galvanic separation of all interfaces ensures that earth loops and transients do not
interfere with communication. To keep visits to the site to a minimum, a watchdog monitors the modem, ensuring constant
readiness, and remote reconfiguration means that changes to settings can be handled without a site visit.
Firewalls are not an issue as data does not use the internet, and with call-back security it is impossible for either accidental
or deliberate access to any equipment attached to the modem. The modem is simple to configure using the Westermo TD-tool software; standard commands can easily be entered, and
saved configurations downloaded. RS-232 connections can be made using screw connections as well as the standard D-sub.
The modem is designed to be connected to devices with no ability to control dialling, so special functions like data dialling
and DTR dialling are provided to enable these devices to automatically establish connections.
