RMS-300v2 - The Super Remote Monitoring System

Use RMSv1 to monitor battery levels, room temperature, signal strength (RSSI) on radios and more. RMSv1 has 8 onboard volt meters giving it the ability to measure dc voltage from 0 to 60 volts with 12 bit accuracy. RMSv1 also has 3 power relays giving it the  unique ability to turn on/off devices remotely using an Internet connection. RMSv1 has 5 multi purpose digital I/O input pins, use them to monitor motion sensors, door contacts etc. Monitor all this information remotely over an Internet connection using an ordinary web browser or the supplied software utility. RMSv1 gives you direct hardware control of fans, lights, computers, radios, etc... No more guessing what your battery levels are.  No more wondering if your signal strengths are at an acceptable level.  No more long drives to reset a fussy radio.  Let RMSv1 do this all remotely via the Internet. The ultimate in remote voltage monitoring.

Put any circuit on the Internet with RMSv1!  Custom built firmware software available upon request.  Other hardware and software modifications available by special order.  Please refer to the contacts at the bottom of this page.

Connect any 10 - 60 volts dc power supply to the power inputs on the terminal block that is beside the on/off switch (See figure 1) Connect a Ethernet cable to the rj-45 jack on the RMSv1 board. Turn the device on with the on/off switch.

Note1: 12 gauge wires should be used for the power input. Keep the length as short as reasonably possible.
Note2: RMSv1 units should be mounted inside a steel enclosure that is grounded properly to prevent Electro Magnetic Interference.

We recommend configuring RMSv1 before deploying it in the field. Simply plug RMSv1 into a hub or switch using a standard Ethernet cable or directly into a computer using a crossover cable.

When RMSv1 is first turned on it checks to see if it has been previously configured. If it has, RMSv1 will use the settings you have provided. If RMSv1 hasn't been previously configured, it will then use default values stored in the onboard EEPROM. You may at anytime restore the RMSv1 device to factory default values by pressing and holding down the micro push button switch located by the Constant Current Port connector, and then turning the RMSv1 device on with the on/off switch. The default values consist of a Mac Address, IP number, and password. The default Mac Address is 00:00:00:12:34:56. The default IP number is 10.10.10.10. The default password is "public".

Run the supplied RMSv1 software and select from the Connect To:   box 10.10.10.10 and then hit the Auto Add Route button. This adds a route to IP address 10.10.10.10. Next press the Auto Ping button. The RMSv1 device should respond to the pings and be ready for further configuring. Press the Acquire Data Button. The display should be filled with values for Mac address and voltage readings as well as relay settings and temperature. Adjust the Mac Address, IP number and password you want the device to have. Caution must be taken when configuring the device, entering incorrect values may cause you to lose connectivity with the  device permanently, forcing the need for a firmware reset. See the FAQ for more information on setting the Mac Address. Once you have RMSv1 configured properly, it is ready to deploy in the field. Below is some basic examples of how to install the RMSv1 unit.

To measure your main battery power supply, run a wire from the positive side of the battery bank to one of the ADC 0-30v positive inputs. Run a second wire from the negative side of the battery to the corresponding ADC 0-30v negative input as shown in Figure 2.  Connect RMSv1 to the internet with a common Ethernet cable and monitor the voltage level of your battery bank with user friendly remote monitoring software. (As an alternative, a web browser may be used to view RMSv1 output.)

 Note: The first two ADC inputs are special, as they can be configured for 30 volt or 60 volt operation. To configure ADC input number 1 for 60 volt operation, simply remove the jumper from JP6. To configure ADC input number 2 for 60 volt operation, simply remove the jumper from JP7. When the jumpers are installed, normal 0-30 volt operation is selected.
 
 

Wireless Inc � (now YDI �) radios have an external RSSI port. Checking signal strength by climbing a tower with a voltmeter is difficult, expensive and time consuming. RMSv1 makes this process much easier. Simply have a cable made with a BNC connector at one end, attach the BNC connector to the radio and run the cable into your equipment room. Strip the cable so that the center core and outer shielding are separated. Twist the shielding mesh together to form a single wire. Attach the solid center core to the positive input on one of the RMSv1 Adc 5 volt inputs and attach the twisted ground shielding to the negative input on the corresponding RMSv1 Adc 5 volt input (see Figure 3). Connect RMSv1 unit to the Internet with a common Ethernet cable and monitor the signal strength of your radios quickly and safely with the included user friendly remote monitoring software.

Turning Devices ON/OFF

To make any device remotely reset able, simply cut one of the wires in the power cord of  a device. Attach one side of the cut wire to the COM terminal on one of the Power Relays. Attach the other side of the cut wire to the NC (normally closed) terminal on the corresponding Power Relay. Reset your device at any time using RMSv1 software.  Note: in the Normally Closed configuration, power still flows to your device even when the RMSv1 device is turned off.  Virtually any 1 to 240 volt AC or DC device can be turned ON/OFF remotely this way. The two small Power Relays can pass up to 5 amps each, the larger Power Relay up to 15 amps!.  For devices that should be by default turned off, use the COM and NO (normally open) configuration. Figure 4 illustrates just one of the many ways you can set up devices for remote reset.

Using the i/o pins to monitor door contacts

To give your equipment room some security you can use widely available common door contacts. These contacts allow current to flow through them when they are in close proximity with each other. RMSv1 can sense when the contacts are together or apart. The diagram below (figure 5) shows how to use I/o pin 1 to monitor door contacts.

Note1: the LED1 light is on when the contacts are together and off when they are apart.
Note2: each I/o pin has a corresponding LED.
Note3: The pins marked GND and +5v are reserved for future expansion and should not be used.
