What Features Do I Need in an SNMP RTU?

Here are 5 essential features that your SNMP RTU must have:

1. Discrete alarm inputs (also called digital inputs or contact closures): These are typically used to monitor equipment failures, intrusion alarms, beacons, and flood and fire detectors.
2. Analog alarm inputs: Analog alarms measure continuously variable levels of voltage or current. Analog alarms monitor temperature, humidity and pressure, all of which can critically affect equipment performance.
3. Ping alarms: An RTU that supports ping alarms will ping devices on your network at regular intervals. If a device fails to respond, the RTU will send an alarm as an SNMP Trap.
4. Control relays: An RTU with control relay outputs will let you operate remote site equipment directly from your NOC.
5. Terminal server function: Your RTU can also serve as a terminal server to remote-site serial devices. Your devices connect to the RTU's serial ports, giving you immediate Telnet access via LAN from your NOC at any time.

DPS Telecom offers SNMP RTUs that meet all these requirements - and offer stand-alone local visibility through any web browser, expandable alarm capacity, LAN access via dial-up connection and more.

The NetGuardian 832A 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 or DCPX, e-mail, or pagers.
