C nfigurati n
Setting up RMS-200
Connect 8 - 60 volts dc power (minimum 500 ma) to the green terminal block that is
beside the on/off switch (See figure 1). Connect an Ethernet cable to the rj-45 jack on the
RMS-200 board. Turn the device on with the on/off switch. It takes the RMS-200 board
approximatel 30 seconds to bring up the Linux operating s stem. The RMS-200 will
signal it is read b first blinking the green status light in a continuous heartbeat
sequence. After a few seconds the red alarm leds will displa a light sequence. The
board is now full booted up and is read for configuration.
Note1: RMS-200 units should be mounted inside a steel enclosure that is grounded
properl to prevent Electro Magnetic Interference.

RMS-200 is p wered up, N w What ?
We recommend configuring RMS-200 before deplo ing it in the field. Simpl plug RMS-
200 into our network or computer using an Ethernet cable (Straight or Cross).
When RMS-200 is turned on it boots the Linux operating s stem and uses the values
stored in its configuration files to bring up the s stem. The default values consist of an IP
address, username, and password. The default IP address is 10.10.10.10. The default
username is root. The default password is pass.
Note: You ma at an time restore the RMS-200 device to
factor default values b pressing and holding down the
micro push button #2 located near the console port and then
turning the RMS-200 device on with the on/off switch.
Release the button when the alarm leds start to flash. When
the alarm leds stop flashing, the RMS-200 unit will be read
to configure.
Give our computer an ip address in the 10.10.10.X class. For instance use 10.10.10.1.
Set our computers Netmask to 255.255.255.0 There is no need to set a Gatewa at this
time. Open our favorite web browser and enter 10.10.10.10 into the address bar, press
enter or the go button. You should be presented with a password box like the one below.
Enter in the default username and password then press the OK button. You will be taken
to the RMS-200 Home page. This page contains an overview of all of the functionalit of
the RMS-200 board.

In the left side panel, click on the Setup icon. This takes ou to the S stem Setup area
shown below.
Here ou will want to visit the following areas: Compan Setup , Network , S stem Time ,
and Change Password. Adjust the Station Name, Location, Domain Name, IP Address,
Subnet Mask, Gatewa , DNS, and password ou want the RMS-200 device to have.

R E M O T E M O N I T O R I N G M A D E E A S Y !
Caution must be taken when configuring the device, entering incorrect values ma cause
ou to lose connectivit with the device, forcing the need for a factor reset. Once ou
have RMS-200 configured properl , it is read to deplo in the field. Below are some
basic examples of how to install the RMS-200 unit.
Installati n
Basic installati n example 1
Monitoring your Battery Bank
To monitor our main batter power suppl , run a wire from the positive side of the
batter bank to one of the Voltmeter positive inputs. Run a second wire from the negative
side of the batter bank to the corresponding Voltmeter negative input as shown in Figure
2. Connect RMS-200 to the internet with a common Ethernet cable and monitor the
voltage level of our batter bank with a web browser.

Basic installati n example 2
Signal strength on Link C Radios
Radios that have an external RSSI port for checking signal strength can be monitored
with ease. Simpl attach the RSSI output from the radio to one of the Voltmeter inputs on
the RMS-200 board (see Figure 3). Monitor the signal strength of our radios with a web
browser and/or have RMS-200 alert ou b email if the signal falls below a certain
threshold.
FIGURE 3

Basic installati n example 3
Turning Devices ON/OFF
To make an device remotel reset able, simpl 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
Rela s. Attach the other side of the cut wire to the NC (normall closed) terminal on the
corresponding Power Rela . Reset our device at an time using RMS-200. Note: in the
Normall Closed configuration, power still flows to our device even when the RMS-200
device is turned off. Virtuall an 1 to 240 volt AC or DC device can be turned ON/OFF
remotel this wa . The two small Power Rela s can pass up to 5 amps each, the larger
Power Rela up to 15 amps!. For devices that should be b default turned off, use the
COM and NO (normall open) configuration. Figure 4 illustrates just one of the man
wa s ou can set up devices for remote reset.
FIGURE 4

Basic installati n example 4
Using the alarm pins to monitor door contacts
To give our equipment room some securit ou can use widel available common door
contacts. These contacts allow current to flow through them when the are in close
proximit with each other. RMS-200 can sense when the contacts are together or apart.
Program the alarm pins to send an email, run a custom file, and/or toggle a rela when
the door gets opened. The diagram below (figure 5) shows how to use Alarm pin 5 to
monitor door contacts.
Note1: the LED5 light is on when the contacts are together. This is the armed position.
Note2: each Alarm pin has a corresponding LED.
FIGURE 5

The Relays
FIGURE 6
RMS-200 has three power rela s for remote control of AC/DC powered equipment. Each
rela has a manual override button that can toggle the rela ; useful for on-site testing.
Each rela also has a jumper shunt connector that allows the rela to be engaged
manuall for hands free testing.
Control of each rela can be done with a web browser. The picture below shows a portion
of the RMS-200 rela s web interface. In the picture below all rela s are in the default
"Normall Closed" position. B clicking on the rela 1 icon…

The rela will be toggled to the "Normall Open" position as shown below.
The rela s can also be toggled with RMS-200 rela Scripts. Rela scripts are made up of
simple commands that control the rela s. Complex rela actions can be performed to control
our equipment. For example; starting a generator.
Below is a screen shot of making a rela script to toggle rela 1 on, wait 2 seconds, then
toggle rela 1 off again.
Each rela can have a name and its actions defined. Below is a screenshot of a rela
script that turns a pump on for 30 minutes and then turns it off again.

Control of the RMS-200 rela s can also be done b using telnet or ssh. Below is an
example of using the rmsrelay command to toggle rela 1 on and off.
Below is an example of reading the status of Rela 1 using the command line interface.
Note the rela 1, rela 2, and rela 3 file will contain a "0" when the rela is in the "Normall
Open" position, and will contain a "1" when in the "Normall Closed" position.

An example of running a rela script on the command line using the rmsscript program.
The example below runs rela Script 1.
PHP programmers ma want to write their own programs to control the rela s. Below are
two example PHP functions that use the PHP s stem command to turn rela 1 on and off.

Need M re Relays?
If the three on board rela s on the RMS-200 board are not enough for our needs, ou
can add five additional rela s b adding a USB rela board.
The USB Rela Board gives ou control of 5 SPDT rela s for general purpose use via the
standard USB Bus. See the USB Rela Board user manual for additional information on
how to hook up the USB Rela Board to our RMS-100, RMS-200 or RMS-300 unit.
To access the Rela Daughter Board interface, go to the Device Manager and click on
the USB Rela Board Icon shown below.
