Page 8: Connecting To The Dc-Rmcu1 Via The Internet
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 70‐B3‐D5‐6B‐3. addresses all start with a base address of 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 ... -

Page 12: Snmp Traps Setup
SNMP TRAPS SETUP This section is simplified, and meant for network administrators who already understand SNMP traps and how to configure capable equipment into their system. For those who want to understand the benefits of using SNMP traps, you can search for training material online under “SNMP Traps”, “MIB Browsers”, and “SNMP Monitoring”. The MIB file for the DC‐RMCU1 can be downloaded from the DC‐RMCU1 after you connect to it with your browser. Go to the Device Setup page and log in to the DC‐RMCU1. Halfway down the page there is a link to the MIB file. Right click on the link and click “Save Link As” to download the file. After download, import the MIB file into your MIB browser or Monitoring software to configure it for use with the DC‐ RMCU1. When the MIB file has been loaded, complete the “SNMP Setup” section on the “Network Setup” page of the DC‐RMCU1 to configure it for use with your monitoring solution. The DC‐RMCU1 will send traps for all configured alarm conditions including bootup, temperature, analog alarms, and digital alarms. 12 of 32 January 20, 2016... -

Page 15: Device Info
Device Info A custom site name can be entered here, and the model number, serial number, software version, and hardware version are shown here. Logging TheDC‐RMCU1will log all measurements and alarms to an SD card that is plugged into theDC‐RMCU1board. Users can set the rate here, as well as clear the card, or append new measurements. The CSV log file can be downloaded here, as well as the Status page. You can also examine the log file using a terminal connection through the USB port. If the SD card fills up, the oldest sample is discarded when a new one is stored. TheDC‐RMCU1custom device name is stored with the logged data, so that the source of the card can be identified after it removed from the RMCU. A DC‐RMCU1 connected to a battery backup power system can monitor and log information about AC mains power outages, as well as all the other measurements for as long as the battery backup lasts. When a log file reaches 5 MB, it is renamed, and a new one is started. Download all log files before clearing the log. With REV 2.4 Firmware, the DC‐RMCU1 has the ability to save log entries when an alarm occurs by choosing “Log Alarms” > “Yes”. You can log alarms, log periodically by setting the “Logging Rate” minutes, log both, or log none by choosing “Log Alarms”>”No” and setting the “Logging Rate” to “0”. The Alarm log entry is identified with label entry before the data entry, as in this example: Date and Time Settings Configuration for all date and time settings. Date and time is battery backed up on the card, and the values are saved in the logged samples. The real‐time‐clock can synchronize it’s time to the network through an NTP server, or it can be set manually if a network is not available. time.nist.gov or pool.ntp.org, The NIST NTP servers can be used by entering or another NTP server address into NTP Server box. Miscellaneous Settings The number of significant digits to the right of the decimal point for the analog channels can be configured here. Note: Best resolution is about 1 in 1000. Temperature can be configured to read in Fahrenheit or Celsius. 15 of 32 January 20, 2016... -

Page 17: Sensor Setup Notes
Sensor Setup Notes The admin user can set custom names for each input or output. Factory set names will be supplied, but they can be re‐ written to be more descriptive, or to manage larger systems. Alarm colors can be set here to represent the proper logical state for your system. If any of the name fields on the left are left blank, the channel will be hidden on the status screen. Digital Outputs can be user‐configured to match your circuit. “Active” refers to the output MOSFET being “ON” or conducting. You may also configure each output to provide a positive or negative 500uS pulse. Button colors and orientation are also selectable. A user‐name for Active and Inactive states can also be configured. Analog and digital alarms are set up in the “Alarm Setup” screen. See the “Alarm Setup” section for more information. 17 of 32 January 20, 2016... -

Page 19: Sensor Calibration Notes
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. 19 of 32 January 20, 2016... -

Analog Channels: DC Amperage Measurement The DC‐RMCU1 comes pre‐configured from the factory to measure amperage on channel 1. A jumper is installed on the board in the channel 1 circuit to configure it to measure +/‐2 V max instead of +/‐ 100 V max to measure the low voltage associated with the meter shunt. DC‐RMCU1 Channel 1 is calibrated to use the 100 Amp / 50mV shunt supplied with the DC‐RMCU1. To measure lower amperage ranges, please contact DuraComm technical support.
