MAMAC - IP Sensor Appliance

 

The Maverick  IP Sensor Appliance incorporates a web server, analog/digital inputs and relay outputs. Power the appliance with any 24VAC transformer, plug it into a hub/router, launch any web browser, punch in the default IP and connect. No custom software to load, no discovery routines, no custom cables, or training.

The IP Sensor Appliance serves up static web pages with dynamic data updates every second or two. Most users can set up and utilize the appliance without any training or support in less than 5 minutes due to the innovative and familiar web browser based configuration.

The Maverick  is an ideal low cost solution for light commercial, residential and remote monitoring applications. The appliance can also be used to enhance existing HVAC control systems by adding email alerts and data logging to critical points.

 GENERAL:

The Maverick IP Sensor Appliance has an embedded lean TCP-IP stack including HTTP, SMTP, DHCP, DNS, FTP, and ARP.

The Maverick also has XML embedded with formatted input & output data. In this way, the Maverick can communicate directly with any IT system which has an XML parser. Similarly, any simple JavaScript can be used to communicate and acquire HTML data. These unique features enable the Maverick to function as a extremely low cost XML & HTML node for large enterprise IT systems.

INPUTS & OUTPUTS:

The Maverick is available in two I/O versions:

1. First version has 8 analog or digital inputs.

2. Second has 4 analog or digital inputs and 4 relay outputs.

The analog inputs can be specified to be voltage or current inputs. On voltage input versions, the appliance can be field configured for 0-5 or 0-10 VDC inputs. Both analog versions (voltage or current) accept 10 VDC maximum as digital input. The output relays are rated for 5 Amps @ 250 VAC and can be used for pilot duty or light load switching directly.

Any input can be assigned to control relays 1 through 4. An output can be controlled by an input, and/or by time based control. If an output has both input and time control, the time based control will force the output on and override the input during "ON" time. However, if time based control is off, input control will take over and force the output on if the value is above/below set point.

The most powerful feature the Maverick has is browser initiated manual control. Any output can be controlled remotely with a web browser running on a cell phone, PDA or a laptop. In this way, if an email alert is received, the user can remotely control the output manually and handle the emergency. Using email alerts, the load can be operated manually until a convenient time to despatch a service technician.

EMAIL ALERTS:

Biggest short coming of all existing control systems is their inability to directly send email alerts and alarms. The Maverick appliance has a very user friendly email alert capability and can send email alerts to up to two different addresses. Email alerts can be configured on all inputs and the Maverick also has the capability to attach a comma separated log file to the email alert. In this way, the user does not only receive an alert but also can parse the log file and know why the alert is coming.

The Maverick appliance can also send email alerts in case of a power outage. The appliance logs the time the power went out and when the power is restored, sends an email with time stamp when the power went out and when it was restored.

Similarly, the appliance can be configured to send an email if the DHCP IP assignment has been changed. In this way, if the Maverick is running as a DHCP client, it can keep the users abreast of it's DHCP IP assignment and the user does not have to discover the appliance.

DATA LOGGING:

The appliance can log 2048 samples for each input. The logging interval can be from 1 second to 99.99 hours. Data is logged in a standard CSV file and can be reviewed with Notepad, WordPad, Excel or any other software application which can open comma separated files.

The Maverick also uses a JavaScript which runs on the web browser to display the logged data as a graph. The X scale (sensor value) and the Y scale (time) on the graph can be adjusted. As a result, the graph can be plotted to show only the relevant data.
