NetGuardian 832A G5: High Capacity SNMPv3 Alarm Collector

Star Rating Average user rating: 4.5 out of 5 stars based on 75 reviews from the install base.
The NetGuardian 832A: A large-capacity RTU that monitors 32 discrete alarms and 8 analog alarms, pings 32 network elements, controls 8 relays, provides LAN reach through access to 8 serial ports, and reports via SNMP v2c or DCPX, e-mail, or pagers.

Versatile and Capable SNMPv3 Alarm Collection

  • High Capacity: 32 discrete alarms points (expandable to 176), 32 ping alarms, 8 analog alarms, 8 controls, and 8 serial ports.

  • Reports alarms via SNMPv1, SNMPv2c, SNMPv3, or DCPX.

  • Wireless Connection Option (either CDMA or GSM).

  • GigE SFP Fiber Interface option.

  • New!16S option: get 8 additional serial data ports

  • T1/E1 Interface option.

  • DNP3 Protocol reporting option.

  • Ping method via SNMPv1 GET - Get more important status info from your ping targets.

  • Reports alarms to multiple SNMP managers or TMon Remote Alarm Monitoring System so it's easier than ever to support a more secure redundant master architecture.

  • Dual Ethernet support for secure network access, both NICs have access to the NetGuardian but not to each other.

  • 8 high-speed (110K) serial ports provide multiple user LAN-based reach through access to PBXs, switches, and any other device with a craft port or serial only interface. (Similar to terminal server functionality).

  • Integrated 4 port 10/100 switch allows functionality with the NetGuardian SiteCAM for visual site surveillance

  • HTTPS (via SSL) with optional Hardware Accelerator

  • RADIUS authentication

  • Alarm point grouping provides severity levels, custom virtual alarms and more

  • RoHS 5 approved, for overseas clients requiring RoHS compliant units

  • Alternate dial-up reporting path in case of primary communication path failure

  • Configure and monitor via Web browser

  • E-mail and pager notifications

  • Free tech support and upgrades

  • Free Windows-based utility for off-site editing and remote provisioning via LAN

  • Multiple customization and expansion options:

    • Start with NetGuardian-C5 (16 discrete alarms, 16 ping alarms, 8 analog alarms, 2 controls, and 4 serial ports) and expand to the capacity you want

    • Integrate with the Building Access System

    • Add sensors for temperature, humidity, etc.

    • Integrate site video surveillance into the NetGuardian web interface to help confirm alarms and increase site security.

    • The NetGuardian hinged back panel accessories provide alternatives for wiring your alarm points. Wire wrap, screw-lug terminations, and punch block are some of the wiring options available.

    • Multi-layer, multi-user, multi-privilege security system.

Migration Tactics for 832A G4 Users

For NetGuardian 832A G4 users looking at substantial new deployments, you might want to consider migrating to the new G5 platform. This enhanced RTU gives you the same alarm capacity as the G4, but with many new capabilities. including increased processor speed (for a faster web interface), advanced hardware (more memory for features), and enhanced security options (like SNMPv3, hardware acceleration, and RADIUS authentication).

The G4 firmware is now in maintenance-only mode, whereas the G5 is actively being developed. This opens the door for many new features down the road. Also, since the G5 is newer, it will also feature a longer product life.

The migration path to the G4 couldn't be easier. The pins for the alarm, relay, and power connections are the same - so projects designed for the G4 will work fine with the G5. See chart below for a quick comparison:

Common use cases for the NetGuardian 832A G5

Like its predecessors, the 832A G5 is built for larger sites. It has 8 control relays and 32 discrete alarms and also has analogs ("832A").

It remains among the most popular DPS RTUs because of its breadth of functions. In particular, the 8 serial ports allow legacy devices to be brought under your single monitoring umbrella.

In the age of the 832A G5, the G4 is still sometimes deployed by organizations who highly value consistency and standardization (and who do not need the improved security and intelligence features of the G5).
