Description

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 synchronizing 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 minimize visits to the site, a watchdog monitors the modem, ensuring constant readiness. Remote reconfiguration allows changes to settings to be handled without a site visit.

Firewalls are not an issue as data does not use the internet. 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.

End of Life Product - No Replacement
