New Version Now Shipping!
The description below needs some updating to match our new features, but to give you a quick rundown on the changes, we now support voltages of up to +48VDC, the shunt input supports both high and low side shunts, and the biggest change of all: This version of the SiteMonitor now includes a web interface, so now all you need to do day to day management of a SiteMonitor is a Web Browser.
Our SiteMonitor Products permit the monitoring and control of equipment at any site which has IP connectivity. Designed to provide low-cost SNMP monitoring and control, the SiteMonitor products are the perfect addition to any remote Repeater Site, or to any equipment you want to be able to monitor via SNMP.
The base unit is the basis of the entire system. It connects to an ethernet-based TCP/IP network and accepts SNMPv1 queries to permit monitoring and control of all attached devices. In addition to the built-in inputs and outputs, the base unit also has an expansion port which will permit the addition of various expansion modules as well. It is also DIN-rail or wall mountable - or you can set it on a rackmount shelf.
The base unit includes a few built-in inputs and outputs. The built-in functionality was designed with a small solar site in mind. For many sites, you may only need the base unit.
The base unit has the following inputs:
Dual 12-56VDC power inputs, each metered separately - plug one into a battery-backed source, and one into a line-powered adapter, or hook it up to any other power source(s) you'd like. The unit will run off of either one, and you will get an indication of the voltage (if any) from each.
DC +-100mV low or high side shunt input. In DC applications, add a shunt to your system, and receive an indication of the net current though that point in the system.
Switch closure input. Connect to a security loop, or another switch or relay closure output, and get an indication of the status of the closure. Perfect to detect whether the door to your equipment has been opened or whether the security loop through your solar panels is intact.
Relay Output. Control up to 1A at 24VDC. Perfect to switch a remote load (such as a radio) on and off. With our autoping feature (coming soon), this relay can also be cycled automatically if the unit is unable to ping another device for a certain amount of time. This is great to ensure connectivity to a site.
Internal Temperature Sensor. There is an on-board temperature sensor built right in. Read an approximate temperature of the enclosure the SiteMonitor unit is in so you can tell if your equipment is overheating or getting too cold.
If the built-in connections don't completely fit your needs, there is an ever-growing set of expansion units available. If you don't find one which fits your needs, feel free to contact us so we can either point you in the right direction, or perhaps build a specialized expansion unit for your particular application in the future.
We also provide a very basic Windows application which will allow you to configure the unit and perform basic control. But the real strength of this unit is when you combine it with third party SNMP applications. For instance, you could use MRTG to graph your temperature and voltages, or another application to monitor and control your networks.
