Overview: NetGuardian 240T
The NetGuardian 240T is a feature-rich RTU that gives you the power to report up to 40 contact closures over T1 or E1.
Are your sites without LAN lacking proper alarm coverage? Poor visibility over any part of your network is a recipe for unanticipated outages that cripple your operations, cost you time and money, and upset your customers. But getting LAN to a site can be very expensive and impractical. You need an RTU that can give you total visibility over your sites that only have T1 or E1 connectivity (See Ordering Options for E1).

The NetGuardian 240T has 40 discrete sensors, and communicates with up to 7 devices via LAN over T1.
Up to 40 Discrete Points for Thorough Coverage
The new NetGuardian 240T can give your site the alarm reporting you need when LAN just isn't an option. The integrated 7 port 10/100 BaseT switch delivers LAN to 7 other devices at the site, eliminating the need to buy an expensive LAN transport card. In fact, the 240T is less expensive than installing a LAN card from your transport manufacturer (which doesn't do any monitoring at all). This makes installing the 240T a "no-brainer" decision.
The NetGuardian's back panel with dual power feeds, dual fuse and indicators, a D-Wire sensor port, amphenol connections, 7-Port switch, and RS232 expansion port.
The NetGuardian 240T's integrated T1 interface supports SNMP and DCPx reporting protocols, as well as standard link Frame Relay and PPP. The device comes standard with support for up to 40 "software reversible" discrete alarms (supports both N/O and N/C), 6 general purpose analog inputs, 2 control relays, and up to 16 D-Wire sensors.
The unit's dual power inputs, with a variety of available input voltages and connector options, give you extra reliability in the event of a power failure. The unit's front panel comes with 8 standard LED lights, a built-in speaker, and an LCD monitor menu.

The NetGuardian 240T includes an easy-to-navigate web interface that boasts several time-saving new tools. Menus load very quickly, and alarm statuses update automatically without requiring a page refresh. Look below for screens of the new setup wizards that make it easy to configure email and SNMP notification schedules.
The NetGuardian 240T web interface
The NetGuardian 240T also includes the Edit240T windows application that allows you to create and edit multiple configuration files for different NetGuardians without being connected to them. You can use the Edit240T software to backup and restore your valuable provisioning information if a re-load becomes necessary in the future. The configuration files can easily be downloaded into the units via LAN, which saves time during installation.

T1 WAN Settings
The NetGuardian 240T has the option of supporting T1 or E1 transport connectivity. In an E1 configuration, the name will change from "NetGuardian 240T" to "NetGuardian 240E". These options can be specified during the order process. E1 is common outside of the US. If you are based in the United States, you should generally choose T1.
The NetGuardian 240T is perfect for sites without LAN connectivity. The NetGuardian 240T uses T1 to connect your devices. Plus, it uses the time-tested design of the NetGuardian 832A, but features 2 controls, 40 discretes, and up to 8 analogs. It can also provide LAN to up to 7 external devices, all for less than it would cost to install a LAN card.
