DESCRIPTION
The new DC-RMCU1 DC-Powered Remote Monitoring and Control Unit, provides the ability to remotely monitor AC Line
voltage up to 300 VAC, up to 6 DC Voltages and 1 temperature, monitor the status of up to 4 external alarms, as well as the ability to
remotely control the state of 4 digital open-drain MOSFET outputs, all via the internet using any standard web browser. The Channel 1
DC voltage input is configured at the factory to measure current using the included 100 Amp/50mV shunt. Additional channels can be
configured at the factory for current measurement. A mobile friendly version of the status page is also included. Alarms and email
notifications can be configured for the 6 analog voltage channels (high and low voltage), and email notifications can be configured for
the Alarm inputs. A high-temperature alarm threshold can be configured to send an email notification, as well as control one of the
digital outputs internally. The DC-RMCU1 also sends SNMP Traps for alarm conditions. The DC-RMCU can also be set to log
measurements to a 2 GB internal micro SD card, and the measurements are time-stamped with a real-time clock.
Guest users will see the status page that displays the AC Voltage, measured values and alarm condition of all active voltage
channels, temperature value and alarm condition, as well as alarm input status, and control status.
Admin and Control Users will be able to configure all of the input and output settings, and set the state of the digital outputs.
Admin and Control users can set device settings for logging, time, and Site Name.
Admin users have exclusive control of network configuration, including manual time setting or NTP, soft reboot of the DC-
RMCU1, factory reset of the entire configuration, and Control or Admin user passwords.
The DC-RMCU1 comes with the DuraComm three-year warranty.

CONNECTING TO THE DC-RMCU1 VIA THE INTERNET
Prerequisites
SystemadministratorsmustdecidewhethertheDC‐RMCU1willoperateonthenetworkwithDHCPorafixedIPaddress.
Thefactory‐setDC‐RMCU1willhavethesestaticaddresses:IPaddress:192.168.100.220,gatewayaddress:
192.168.100.1,netmask:255.255.255.0,andDNSaddress:192.168.100.1.
IfyouconfigureittouseDHCP,theDC‐RMCU1willrequestanavailableIPaddressonyournetwork.Youwillneedto
determinewhataddressithasbeengiven.
IfDHCPisnotused,systemadministratorsmustalsochooseanunusedIPaddress,andothernetworksettingstousein
theNetworkSetupscreen.Systemadministratorswillalsoneedtochooseanemailserviceandaddresstousefor
notifications,ifneeded.ThesewillbeusedintheEmailSetupScreen.
DETERMINING THE IP ADDRESS OF THE DC-RMCU1
PoweruptheDC‐RMCU1thenconnecttheDC‐RMCU1tothenetworkwithanEthernetcable.A3footcableisprovided.
Using DHCP
TheDC‐RMCU1willattempttoconnecttothenetworkviaDHCPwhenitisfirstconnected,orwhenyouperforma
factoryreset.
YouwillneedtogettheIPaddressinoneoftwoways.YoucangettheIPaddressfromtheDHCPserver’sclientlist,or
youcanuseaPConthesamenetworktoscanforthenewIPaddressbyusingasoftwaretoolsuchasAngryIPScanner.
InAngryIPScanner,youshouldaddtheMACaddress“Fetcher”under“Tools>Fetchers”.TheDuraCommMAC
addressesallstartwithabaseaddressof70‐B3‐D5‐6B‐3.WritedowntheIPaddressoftheDC‐RMCU1,then
proceedtothesectioninthismanualnamed“OpenaWebConnectiontotheDC‐RMCU1”.
Using Static DC-RMCU1 IP and Network Configuration
IfyournetworkisnotsetupforDHCP,youwillneedtomanuallyconfigurethesettingstomatchthenetworkitwillbe
usedon.Beforeyoucandothat,youwillneedtoconfigureacomputertotalktotheDC‐RMCU1atthedefault
configurationsettingsshownabove.WewilluseWindows7asanexample.Otheroperatingsystemswillvary,butthe
overallconceptisthesame.
1. DisconnectyourPCfromallnetworks.
2. ConnectitdirectlytotheDC‐RMCU1withanEthernetcable(YoumayneedtouseanEthernetcrossovercableifthePC
doesnotautomaticallydetectthisconfiguration).
3. OpenthecontrolpanelonyourPCandselect“ViewNetworkStatusandTasks”
4. Clickon“ChangeAdapterSettings”ontheleftsideofthescreen.
5. Rightclickon“LocalAreaConnection”andclickon“Properties”
6. Clickon“InternetProtocolVersion4(TCP/IPv4)”tohighlightit,thenclickthe“Properties”button.
7. Beforeyoumakeanychanges,recordtheexistingsettings,sothatyoucanchangethembackwhenyouarefinishedsetting
uptheDC‐RMCU1.
8. Enable“UseTheFollowingIPAddress”
9. Nowenter192.168.100.221fortheIPaddress.
10. Enter255.255.255.0Subnetmask
11. ClickOKtosavethenetworkconfiguration.
12. Jumptothesectioninthisownersguidenamed“OpenaWebConnectiontotheDC‐RMCU1”tologinandenterthefinal

Sensor Calibration Notes
SensorcalibrationsisprovidedtoconvertthenativevoltagemeasurementsoftheDC‐RMCU1intootherunitsforlinear
transducers.Forexample,thecurrenttransducerprovidedwiththeDC‐RMCU1willhave50mvacrossitwhen100Amps
isflowingthroughit.Theconversionfactorisenteredonthispage.
Channelsthatonlymeasurevoltagedonotneedaconversionfactor,andtheentriescanbeleftat0.Whenaphysical
jumperisplacedonchannel1,itischangedfroma+/‐100Voltmaxrangetoa+/‐2Vmaxrangetogainresolutionfor
smallervoltages.The“Jumpered”drop‐downmustbesetto“Yes”forachannelwithajumpersothatitisscaled
properly.Sinceacurrentshuntisdesignedforatypicalvoltagedropof50mvatfullscale,Channel1isconfiguredwitha
physicaljumper,the“Jumpered”dropdownissetto“Yes”,andcalibrationfactorsareentered.Since0vwillbeequalto
0Amps,wedon’tneedtochangethelowerleftcalibrationfactors.Wechangetheverticalmaximumto0.05VDC
(50mv)andthehorizontalmaximumto100.Wethentype“Amps”astheuserunits.
Bydefining2pointsonthelineargraph,wecancalibrateanylineartransducer,withinthevoltagemeasurementrange
oftheDC‐RMCU1.Thiswillallowyoutouseabroadrangeofexistingtransducerstomeasuremanydifferentthingslike
pressure,temperature,force,etc.Even4‐20matransducerscanbeusedbymeasuringthevoltageacrossaresistor
placedinserieswiththetransducer.Thesetransducersrequirethatboththelower‐leftandupperrightcalibration
pointsbeconfiguredonthegraph.
