How Do I Know What Remote I Want?

RTU Choices
Choosing the right RTU
doesn't have to be complex.

Selecting the right RTU for your remote sites can be overwhelming. When you're trying to find the right balance of capacity, interface, and features - how do you know what you really want?

Before you decide on an RTU, you should consider its short-term and long-term effect on your network monitoring strategy. You want an RTU that will both immediately improve your network visibility and support your overall upgrade plan to support your future monitoring goals.

Here are the 3 crucial factors that can help you make a well-informed buying decision:

1. Take an Inventory of Your Current Network Monitoring Equipment

You may think that adding new RTUs requires a completely new alarm monitoring system, but that's not necessarily true. Before you shop around, take an inventory of your current network monitoring equipment. You want to select an RTU that meets your current requirements and is compatible with your existing network transports.

Here's some questions that will help you start your network monitoring inventory:

  1. How many remote sites need to be monitored?
  2. What is the protocol and transport of the RTUs you're currently using?
  3. How many alarm points (discrete inputs) do you need to monitor at each site?
  4. What dedicated facilities do you already have in place to transport RTU data?

2. Decide What Features You Need to Support Your Anticipated Growth

Before you select a remote, think about what your ultimate goals are for your network monitoring. What alarm capacity do you need to support your future network growth? What great features do you really want your alarm system to support?

Here are some questions that will help you form your future network monitoring plans:

  1. How many alarm points will your network alarm system monitor in the next 5-10 years?
  2. What alarm monitoring features will you need - discrete alarms, analog alarms, controls, serial ports, local visibility?
  3. What kind of data transport do you want to use, now and in the future - overhead channels, DS0 (56K) circuits, X.25 network, terminal servers, LAN/WAN, other?
  4. What protocols will your remotes use? Are you planning to shift your monitoring to a standard protocol like SNMP?
  5. Do you want to receive alarm notifications via email or pager?

3. Select an RTU for both Your Immediate and Future Needs

Once you've defined your current and long-term network monitoring goals, choose an RTU that meets your present needs and will expand to meet your future needs.
