2.0 Overview
2.1 General Description
Your NEWMAR Site Power Monitor, model SPM-200, web-enables and integrates intelligence to any site’s AC
and DC power system for 24/7 monitoring, alarm condition notification, and data logging of vital electrical
functions. All sensor inputs are programmable, accessible, and managed via the Internet: TCP/IP or SNMP.
View current conditions and log 30 day history of DC and AC power status at remote sites before dispatching
personnel.
The SPM-200 is designed specifically for monitoring power supplies, rectifiers, batteries, converters, inverters,
UPS, power distribution panels, and AC power at communication sites, base stations, outdoor enclosures and
command vehicles via Ethernet or Wireless connection. The unit can be rack, DIN-rail, or wall mounted and is
easily adapted to virtually any make of power system via nine sensor input ports which capture and stream
critical data via the internet for analysis and logging of site history. Web page based programs are easily
user configured for site parameters with up to 50 desired alarm conditions settings and multiple automatic
notification options by e-mail, PDA, and mobile phone via text messaging.
Sites without internet access can use the monitor solely as a data logging instrument that captures and retains
a 30 day history file, ready for download to a spread sheet on a lap top computer during maintenance visits
for recording site history and analysis of component performance and failure conditions.

Note the indication near the top of the screen “Local Time: Time Not Set”. The unit will not graph or log data
until the clock has been set. The SPM has an internal power source that will keep the clock running for about
two weeks without a power supply being connected to the unit. If the unit is disconnected for longer than two
weeks the clock will have to be reset.
The illustrated unit has not been configured yet. The labels down the left column “Temperature” “Volts DC A”,
“Volts DC B” etc. are default names for the SPM’s inputs. You will be able to replace those names with “friendly
names” that mean more to you later on in the configuration process. The unit name in the upper right hand
side: “Newmar SPM” is also a default and can be replaced with whatever you choose.
You have now successfully connected a local PC to the SPM and displayed the initial web page. You have
proved that your SPM-200 is functional and that you can connect to it with a web browser. The next parts
of the manual will cover how to set up the SPM so it can be accessed over the Internet, and how to further
configure the SPM.
4.1.3 Setting the Clock
This section covers setting the clock and configuring your SPM to connect over a network. NOTE: If you don’t
have a network to connect to, the SPM-200 can be used as a simple data logger with a Web interface. The
only item that you must set is the clock, as described below.

To set the clock, click on the “Config” tag on the left side of the webpage. The top part of the Config page
should look like this, see FIGURE 5:
FIGURE 5: The Top of the Config Webpage
Select“Manual–GMT”inthe“Set Clock Method” pulldown. Enter the date and time in the appropriate boxes.
The box asks for the time in GMT, and the offset from GMT for your local area. That is not necessary if you are
settingtheclockmanually.Justsetthelocaldateandtimeandput“0:00”astheGMTtolocaloffset.Besure
to click “Save Changes” when you are done. The date and time should then be displayed at the top of each
page, and the SPM will begin logging data.
Note:TheSPMwillnotadjustforDaylightSavingsTime;youhavetodothatmanually.
It is also possible for the SPM to determine the correct time from an NTP server if one is available. Since the
SPM is not connected to a real network that won’t work now.
4.1.4 Setting Account Names & Passwords
Now, scroll down the Config page until you find the Name and Password Configuration options block. Here,
you can set up to three levels of password protection for the SPM-200, allowing you to restrict which user(s) in
your organization are able to view or change the unit’s settings. Although these settings are optional, Newmar
Power highly recommends that you at least set up the Administrator account to prevent unauthorized
changes to the network and administrative settings.

FIGURE 6: Account Settings
If a given account’s username and password fields are left blank, then the level(s) of access controlled by
that account are available to anyone who connects to the unit. Accounts are listed in order of privilege, from
highest to lowest, and lower-privilege accounts cannot be set unless the higher-privilege accounts above them
aresetaswell;i.e.youcannothaveaControlaccountwithoutanAdministratoraccount,andyoucannot

only account which can access the Config page, and that you must configure this account before you can
configure the Control or View-Only accounts.
Control: this account is able to view all of the web pages except for the Config page, and is able to change
alarm settings on the Alarms page.

View-Only: this account is able to view all of the web pages except for the Config page, but is not able to
change any settings. Once you have configured these accounts the way you want them, click the Save
Changes button. If you have configured an Administrator account, the unit will now ask you to log in with
that username and password before you can continue.
As always, don’t forget to click the “Save Changes” button when you’re done.
At this point you have two options:
1) Continue using the PC and the crossover cable to finish configuring the SPM-200, and later connecting it to
the network it will really use. If you want to choose this option, skip over the section “Setting the Internet
Address” for now, and come back to it later.
2) Connect the SPM to the real network now. To do this, complete the next section now and connect the SPM
to the real network as soon as you’ve set the Internet Address
4.2 Setting the Internet Address
The next step is to set the “IP” or “Internet address of the SPM. Each SPM is initially set to 192.168.123.123 when
it is built so the user can do the initial configuration, but that will probably need to be changed when a unit is
installed.
There are a couple of ways to get an internet address:
• Thesimplestwayistousewhat’scalleda“Static”IPAddress.Astaticaddressisjustwhatitsoundslike,an
address that never changes. If the SPM will be part of a local network, the network administrator may be
able to assign an address.
• Or,theIPaddresscanbeassignedbywhat’scalleda“DHCPServer”.Thisisaserveronyourlocalnetwork
that automatically assigns IP addresses to each device on the network. An address assigned by DHCP is
called a “Dynamic” address, because the address may not always have the same value
• IfyouintendtoconnectyourSPMtothepublicInternetthroughanISP,youwillhavetohaveapublic
 staticIPaddresssothatitcanbereachedfromabrowser.Itmaynotbepossibletogetastaticaddress–
your ISP may only be able to assign a dynamic address. If this is the case, see Appendix A for a solution.
Scroll down on the “Config” page until you see the network settings:

If you have a DHCP server, check the box indicated. Otherwise, enter the appropriate IP address, Subnet Mask
and Gateway address. CAUTION: once you click “Save Changes”, the SPM will IMMEDIATELY switch to the
IPaddressyoujustentered,orattempttoobtainanIPaddressfromaDHCPserver.ItwillNOT respond at
192.168.123.123 anymore. Also note that if you select “DHCP” and there is no DHCP server available, you will
not be able to access the SPM-200 again at all. See 9.0 Appendix B: Troubleshooting #14 which describes the
“Reset” button in order to recover.
If you are sure you have the correct settings, go ahead and click the “Save Changes” button. Now you will
have to disconnect the SPM from the PC and the crossover cable, and connect it to your real network. You
shouldbeabletoaccessitbyopeningabrowserwindowandenteringthenewaddressthatyoujustset.
5.0 SPM-200 Web Page Overview
The Sensors web page is the home page for the SPM-200. It is the page that will be displayed when you first
connect to an SPM. The Sensors Page shows the current value of all the inputs to the SPM. A Sensors Page from
an SPM that has been running a while is shown on the following page, see FIGURE 8:

Note that the default names on the previous illustration have been replaced by names that are more
meaningful in this installation. Some other configuration variables have been changed, such as the
temperature units. Temperature can be displayed in Fahrenheit or Celsius, whichever you choose. The clock
has been set and some of the information in the box at the bottom has been customized as well.
Thisunithasbeenrunningforawhile,soitdisplaysagraphofallthedata.Thisgraphisnotcongurable;it
always shows all the data. Later on you will see a screen that you can customize to show only the data you
want to see.
Note that there is a gap in time on the graph. The SPM must have been turned off over that time span. Note
also that “2 Alarms Tripped” appears at the top of the page. The values for “Helios” and “EBS” are red instead of
black, indicating that these are the values that tripped the alarms.
The inputs are scanned every 15 seconds. This page is automatically refreshed once per minute. You can
force the page to show the newest data immediately by clicking the “refresh” button on your browser.
5.1 Setting Low & High Alarm Trips
The Alarms web page is where you configure the alarms for the unit.

The user selects which data item each alarm covers. In the example above, Alarm#01 is set to trip if the
“Auxiliary Voltage’ input goes above 30.0V. We know it will trip if the value goes above the set point because
“High Trip” has been selected. Note Alarm#06 is set to trip if the same input goes below 22.0V (“Low Trip”). Any
number of alarms can be set on each input value, as long as the total number of alarms is less than 50.
Note how Input Select is pulled down for Alarm#04. This illustrates how the user can select any input for any
given alarm.
When Alarm#01 is tripped it will send emails to the first two email addresses, and both SNMP traps will be
triggered. (We’ll see how to set the email addresses and SNMP traps on the Configuration Page later). Each
alarm can send emails to any combination of the 5 email addresses and 2 SNMP traps. It is common to set
one alarm to send an email to one or more email addresses if an input value exceeds a first threshold, and
set a second alarm to send emails to different address(es) if the same input value exceeds a second threshold.
This allows an escalation procedure to be set up.
If you make changes to this (and any other web page on the SPM-200) don’t forget to click “Save Changes”
when you’re finished. If you don’t, your changes will be lost.
The Logging page graphs selected data over a selected time range, and controls data logging in general.

This page allows the user to select data inputs and graph them over a chosen time period. The graph can
show data over ranges in time from the last 15 minutes to the last month. The user can select any combination
of the inputs to be graphed. (This is in contrast to the graph on the Sensors page, which always shows all the
stored data.). At the bottom of the page is shown the maximum length of the log, in this case 40.16 days. That
means if the SPM-200 has enough room in its memory to store data over that time. The memory is set up as a
circularbuffer-iftheSPM-200hasrunformorethanthattime,newdatawillreplacetheoldonarstin–rst
out (FIFO) basis.
If you make changes on this page you must click the “Update Graph” button for the changes to take place.
If for some reason you want to delete all the data that is in memory, check the “Reset Logs”box.Caution–
there is no way to recover the data after the reset button is checked.
The check boxes only control what data is being graphed, not what is being logged. The SPM-200 always logs
the data from all the inputs. The data can be downloaded to a PC or a similar machine in Comma Separated
Value (CSV) format. CSV is a very simple and general way to store data in a file. Most analysis programs,
such as Microsoft Excel®, can read CSV data. So you can download all the data in memory and analyze it
with Excel®.
Again, don’t forget to click the “Save Changes” button.
