Monitor Quantar Radios with a NetGuardian Q8 RTU

How to monitor your Motorola Quantar radios

The NetGuardian Q8 is a specially designed discrete alarm collection unit for a Quantar-branded base station. It is an excellent solution for monitoring your Quantar radios with a NetGuardian Q8 RTU:

  • Monitors 8 alarm points and issues SNMP/DCPx traps when a fault occurs.
  • 2 internal relays may be activated via remote command from an SNMP Manager or T/Mon.
  • Users may check alarm status via Telnet to view alarms using TTY, Web browser or LED's.
  • It is powered by 13.8VDC, provided by the Quantar.

How to install the NetGuardian Q8

The NetGuardian Q8 mounts behind your Quantar radio and includes a Windows-based configuration utility for programming.

The primary function of the NGD-Q8 is to collect alarms from the Quantar and convert them to SNMP. In addition, because the unit has individual LEDs for each alarm point, you also gain the benefit of local alarm monitoring on the rear of the radio.

NetGuardian I/O details

The LED display also contains status / diagnostic information on the LAN, craft port, relays and power.

The front side of the NGD-Q8 hosts two connectors. The first is an RJ45 LAN interface. The second is a DB9 craft port used for quick and easy access for diagnostic and monitoring purposes.

You will be able to access the TTY interface, but its scope is limited to displaying alarms status, unit diagnostics and setting the IP address. The TTY interface will be accessible from the craft port and via telnet.

There will also be Web Browser that will allow convenient access to the alarm status by anyone (with security access rights) who wishes to browse to the unit. The advantages of this are: faster and easier to use, centralized database, LAN / craft port downloadable.

Background information on Quantar monitoring via DPS

Monitoring Motorola Quantar radios is a likely place to find a DPS solution. That's because DPS gear is often used for monitoring older equipment that must continue to function in today's environments.

Although the Quantar didn't natively include the ability to send SNMP traps, that function grew highly desirable as remote monitoring technology evolved.

While newer radios do include SNMP, that doesn't help the large number of remaining Quantar users.

That's why we took it upon ourselves to modify a NetGuardian RTU to suit the Quantar specifically. We tweaked the I/O to mate precisely with a Quantar. We even had our in-house metal shop build a custom chassis that attaches (backpack-style) to the Quantar directly.

There's really nothing like the perfect fit of a custom device, both from a hardware and software perspective.

What to do if you have a Quantar - or any older gear - to monitor

If you have any type of legacy equipment that you need to monitor or convert to a newer protocol, I can help you.
