Electrical Connections
Hardware Installation
Step 1 - Unpack materials: Remove all materials from shipping box and verify all required components are available
Step 2 - Mount the EMB HubLite on the wall, panel or other appropriate location.
Step 3 –Attach pulse output devices to the pulse inputs on the A7810. For dry-contact
WARNING: After wiring the A7810, remove all scraps of wire or foil shield from the electrical panel. This
could be dangerous if wire scraps come into contact with high voltage wires.
Step 4 - Power-up and diagnostics: A power supply is not provided with the EMB HubLite EMB, therefore it is up to the
installer to provide the required 24VDC. After power is applied, the green “Alive” light in the upper right of the EMB
HubLite should come on and the LCD display will display a series of diagnostic screens ending with the following message
on the LCD display (this boot sequence may require up to 20 seconds to complete):
EMB HubLite Ready

Page 7 A7810 EMB HubLite –Data Acquisition HubLite
192.168.40.50
This indicates that the EMB HubLite has loaded properly and is ready for configuration and connection to the network and
sensors. If the “Alive” light does not come on or the LCD display does not cycle to the above screen, verify that the power
wires and connector are secure, and are providing required power as specified. If after cycling the power, the unit still does
not power up (or if an error message appears in the LCD display) contact technical support. After the A7810 has been
powered up for a minute, the green Alive LED should blink slowly once per second during normal operation.
Alive: blinks once per second while the system is operating correctly.
Alarm: blinks to indicate a problem.
Ethernet Link/Act: On when connected to a hub or switch, off when not connected. Blinks when LAN
traffic is being sent or received.
RS485 RX/TX. The 485TX LED should blink slowly once per second during normal operation. The RX
LED will blink when external Modbus devices communicate with the EMB HubLite.
Step 5–Verify the pulse input LED next to each pulse input terminal blinks in conjunction with the power meter that is
attached to the input. The LED will turn on when the contact terminals are closed, or bridged together.
Basic Network Configuration
Step 1 - Determine the IP addressing needs: The IP address of the EMB HubLite™ HUBLite can be implemented using one
of three methods. Check with the network administrator to determine which method applies. For phone installations, use
"direct connection to laptop" to allow initial configuration.
Static IP address - this is a fixed IP address which is assigned by a network administrator and configured into the
EMB HubLite; or
Dynamic Host Configuration Protocol (DHCP) address - this process assigns an IP address dynamically to the
EMB HubLite when it is connected to the network from a host DHCP HUBLite; or
Direct connection between the EMB HubLite and a single temporary computer such as a laptop. (primary
connection will be dialin or dialout by modem)
You will need the following information from your network administrator: The addresses will be in the form of
“###.###.###.###”), where “#” refers to the numbers 0 to 9.
Static IPAddress
DHCP
Direct Connection to Laptop
IP address: ___.___.___.___
Netmask: ___.___.___.___
Gateway: ___.___.___.___
DNS HUBLite: ___.___.___.___
DNS HUBLite: ___.___.___.___
HTTP Proxy _____________
proxy HUBLite port: ______
IP address: (dhcp assigned)
Netmask: (dhcp assigned)
Gateway: (dhcp assigned)
DNS HUBLite: (dhcp assigned)
HTTP Proxy _____________

IPAddress: 192.168.40.50
Netmask: 255.255.255.0
Gatway: 192.168.40.1
DNS: 70.99.203.62
HTTP Proxy: [blank]
(factory default settings)
Network Address Worksheet
Step 2 - Configure the IP address as selected from the table above. For Direct Connection to Laptop, the address settings
above are set as the factory default, and you may be able to skip to the "Laptop/Computer Setup" section if the factory
default settings are present.
To begin configuration, make sure that the HUBLite displays the start screen:
EMB HubLite Ready
192.168.40.50
If this screen does not appear on the LCD display, press and hold the Menu button on the HUBLite for several seconds and
the message should appear. To change the IP address to the static address assigned by the network administrator, do the
following:
A. Press the Menu button once to get the TCP/IP configuration menu
www.GlobalTestSupply.com

Page 8 A7810 EMB HubLite –Data Acquisition HubLite
[Main Menu]
TCP/IP Config
B. Press the Select button once to select the TCP/IP Config menu options, first of which is DHCP:
[TCP/IP Config]
DHCP on/off
C. Press the Menu button once to see the TCP/IP IPAddress menu:
[TCP/IP Config]
IP Address
D. Press the Select button again to select the IPAddress menu:
[IP Address]
192.168.40.50
E. At this point, the cursor on the display will be blinking on the first number in the IP address on the second
line.
F. To change the number, press the Menu button and the display will cycle through the digits 0-9 as well as
“.”. Once the correct digit is displayed, press the Select button to advance to the next digit and repeat the
process until all the digits are correct.
G. Once the IP address on the EMB HubLite matches the assigned IP address, press the Select button once
more to return to the main TCP/IP menu.
Step 3 - Set the Netmask, Gateway, and DNS HUBLite(s) addresses as noted in the chart "Network Address Worksheet"
using the same technique as shown above. The only change is that after Step B, press the Menu button multiple times to see
the Netmask, Gateway, and DNS setup menus, then push the Select button to set the options.
Note: If DHCP configuration is selected, the IP, Netmask, Gateway, and DNS HUBLite addresses will be obtained
automatically. Simply select the “Enable DHCP” from the first TCP/IP configuration menu.
Step 4 - After the address information has been set, you must reboot the EMB HubLite. Select the "(Previous Menu)" option
after step B above. The menu will then state that the EMB HubLite must be rebooted to take effect. Press the Select button
to allow the EMB HubLite to reboot.
Once the EMB HubLite has rebooted, the new IP address will be displayed on the console. If DHCP addressing was
specified, the HUBLite assigned address will be displayed.
Note: if DHCP is unable to obtain an IP address, the EMB HubLite will use the fallback address of 192.168.0.100.
Laptop/Computer Setup
Step 1 - You must have a computer to access and configure the EMB HubLite. This computer must have an Ethernet
connection (on the LAN or by direct connection) and must have a web browser installed such as Internet Explorer or
Firefox.
Note: If your building already has an existing LAN to which the EMB HubLite is attached, you can use an existing
computer on that LAN. Check with your network administrator for details. If this option is available, use a LAN-connected
computer and skip to the “EMB HubLite administration overview” section below.

Page 9 A7810 EMB HubLite –Data Acquisition HubLite
The remainder of this section will assume the installer has brought a laptop to the site, and will connect the laptop to the
building LAN, or directly to the EMB HubLite. Attach the laptop to the EMB HubLite or LAN as shown in figure 6,
Ethernet hookup.
Step 2 - Attach the Laptop to the EMB HubLite or to the LAN. The A7810 will automatically detect whether a direct or
crossover cable is required, and will reverse polarity accordingly. This feature will allow you to use either a straight
Ethernet cable or a crossover Ethernet cable interchangeably.
If the Laptop is to be attached to an existing LAN, obtain a static IP address (or use DHCP addressing) from the network
administrator.

HubLite. This is the name that will appear on the BMO website service (if subscribed). Specify the data logging period. The
default is 15 minutes.
Step 8 –Decide upon a method of data transfer. (see section later in this document) . If you select the HTTP/Post method to
send data to the BMO website, you can configure this by selecting the “LogFileData, Setup/Upload” page.
A. Make note of the EMB HubLite serial number.
B. Select upload options as needed for time of day to upload the data and retry control.
C. Check the checkbox to allow remote configuration. This will allow you to reconfigure the EMB HubLite from the
BMO web site without having to connect directly to the EMB HubLite.
D. Specify the "Target address to upload data." This is the website address where the EMB HubLite will send the
collected data. If you have an in-house data collection service, you should enter the address of your data HUBLite
in this field. Leviton also provides a service called Building Manager Online that can collect and report data for
you. If you are using the BMO service, the target address to upload data should be set to
http://www.buildingmanageronline.com/upload.php
E. When configuring the EMB HubLite to send data to the BMO site or your own data collection HUBLite, the EMB
HubLite will authenticate itself with the HUBLite by using the serial number and a password. This password must
be supplied here, and can be obtained when you subscribe for the BMO service, or by your database administrator.
F. Click "Apply" to save your changes.
If you select a manual transfer method, remove (blank out) the target address in the Modbus/Upload Data page.

Security
The EMB HubLite has three levels of security. These are “operator”, “user” and “admin”. When using a browser to access
the EMB HubLite, basic http authentication is used to prompt your browser for a username and password. The admin
account uses “admin” as the default password. To change the password, select the Accounts menu from the left side tree
display. Next, select the account name. Click the “Change Password” button to set a new password for the selected account.
admin: This account has full access to modify any of the system settings. The default password is “admin”.
operator: This account may view settings, however may only change modbus alarm ranges and device names.
user: This account can view some system settings including the modbus device status pages and can change nothing.
When using FTP to access the EMB HubLite, you may use the admin account username/password for read-only access.
Log information is stored in /var/log/modbus. For read-write-delete access, use the login name “root” and the admin
password.
The three usernames specified are not able to be changed or renamed, nor can arbitrary usernames be added to the EMB
HubLite. Access is only controlled by setting the password for the three existing usernames noted above.
The “operator” and “user” accounts are disabled by default. These accounts are activated when you first set a password for
each.

Device Configuration
When the “configure” button is clicked from the device details page, the screen will be refreshed, with the same
information, however the device name, alarm settings and console checkbox will be available.
Device Name: This field allows you to specify a name for the device such as “main building power” or other useful name to
indicate the location or function of the device. A name must be assigned to a device before the EMB HubLite will log data
for it.
Low Alarm, High Alarm: Specify a threshold for the alarm. If the data point is recorded below the Low Alarm, or above
the High Alarm levels at the time a log entry is taken, the point will be considered in an alarm state.
Console: Checking this checkbox will cause the EMB HubLite to display this data point on the LCD console. Multiple data
points are rotated about every 10 seconds. The values on the LCD console are updated when the next log interval occurs.
Point Config: Some devices have configurable point features. Most data points are automatically configured and this
option may not be displayed.
Advanced: At the lower right corner of the page, an advanced configuration button may be present depending on the
Modbus device features.
Advanced Configuration Options
The advanced configuration page contains special options specific to the device you are configuring. For the onboard pulse
inputs, the configuration options are shown below. The device serial number and other specific parameters will be
displayed if available.
Specific options available in the Advanced Configuration page vary depending on the features available in the Modbus
Device, as well as the features implemented in the built in EMB HubLite driver.

Manual DeviceAdd Options
Modbus devices may be added manually by clicking on the “add” link on the bottom of the Modbus device list page. This
option is intended for use when adding devices to the configuration profile prior to installing the physical hardware, or
configuring Modbus/TCP devices that will not automatically populate in the Modbus device list.
The manual setup page has several options that must be configured before the EMB HubLite will recognize the Modbus
device. The options are as follows:
Modbus Address: The Modbus device address must be supplied. Note: when configuring a device on a remote
Modbus/TCP gateway, the Modbus address of the remote device must not be the same as any address already listed in the
device list page.
Modbus/TCP Gateway IP: This option allows the EMB HubLite to log data from a remote Modbus device that is attached
to the LAN via a Modbus TCP gateway device such as an EGX or Moxa gateway.
Modbus/TCP Gateway Port: If a remote Modbus/TCP gateway is used, the tcp port of the remote gateway must be
specified. The default TCP port is 502 on most gateways.
Device Name: You must provide a name for the Modbus device to identify it in the device list. This should be something
that will identify the meter location and purpose.
Device Type: This menu will allow the selection of any built in driver or any Modbus Framework template that is available
on the EMB HubLite. It is important to select the driver or template that matches the Modbus device.

Troubleshooting Pulse inputs
If the device you have attached does not appear in the Modbus device list, check the following:
Verify the pulse input connections are correct .
Verify the status LED blinks for the specific pulse input in question. Try bridging the two terminals at the input of the
EMB HubLite to verify the input LED turns on.
Bridge the terminals of the pulse output meter and verify the input LED turns on. This will verify the wiring to the meter
is correct.
Modbus Setup
The Modbus setup page provides several options related to the Modbus RS485 serial port.
EMB HubLite Name: This is the name of the EMB HubLite. This name will be present on all log file descriptors when
uploaded to a central database website such as BMO. It is helpful to name the EMB HubLite based on the physical location
of the system, or building. Note: this feature was labeled “Loop Name” in older firmware versions.
Data logging period: This option sets the log interval for the EMB HubLite. Options range from once per minute to once
per hour. All of the selections are even divisions of one hour. The EMB HubLite calculates the next log time by finding the
next multiple of the log period past the start of the hour. For example, if the log period is 15 minutes, log readings will be
taken at 0, 15, 30 and 45 minutes past the hour. The log period is not calculated based on “15 minutes after the last
reading”
When the EMB HubLite is first started, it will take an initial reading of all the Modbus devices immediately. Following that,
the next log reading will be calculated as a multiple of the log period after the hour. The initial reading is taken to allow the
EMB HubLite to gather information for meters that require demand calculations, as well as provide accurate information
starting when the EMB HubLite is booted.
Modbus/TCP access: The EMB HubLite has a Modbus TCP gateway feature that allows other systems to send queries to
all attached Modbus RS485 devices. This feature allows control of what systems have access to the Modbus TCP gateway
feature. The settings include “no access”, “local subnet only” and “allow any”. This basic security feature only allows
control based on the IP address of the system making the request. The Modbus TCP protocol does not have provisions for
any authentication password or other methods of security. By default, the gateway feature is disabled, and set to “No
Access.”
The Modbus TCP gateway is a feature that allows the EMB HubLite to share the attached Modbus RS485 devices with other
systems such as PCs with software and building control systems. The gateway receives incoming TCP requests, verifies the
length of the packet does not exceed 255 bytes, and forwards the packet to the Modbus RS485 loop. The gateway does not
verify the contents of the packet, nor the target address specified in the request. If the Modbus RS485 device sends a valid
response back, the gateway will return this information to the the system requesting it via TCP. If no response is received, a
timeout failure will be sent to the requester. Because the gateway does not process the contents of the request or reply, it is
possible to query devices on the Modbus RS485 loop that are not specifically supported by the EMB HubLite.
Alarm Setup
The Modbus Alarms section provides the ability to send messages when alarm levels are exceeded. Messages can be sent
by email, SNMP or displayed on the LCD console. Alarms are processed at the end of the data logging period. For more
frequent alarms, shorten the data log interval. Log readings and alarm processing can be set to as often as once per minute.
Display all alarms on LCD console: When checked, all alarm messages are shown on the LCD display of the EMB
HubLite.
SNMPTrap Send Enabled: When checked, SNMP Trap messages are sent after every log period for each data point that is
in an alarm state. The trap includes information about the EMB HubLite system data point, and alarm state. A full MIB is
located on the EMB HubLite, click the MIB link to the right of this option.
SNMPTrap Host 1 (2,3): When SNMP traps are enabled, a trap message is sent to each of the trap host addresses. Specify
the trap host by IP address, not DNS name.
Direct email on alarm. When checked, the EMB HubLite will send an email message when any data point changes its
alarm state.

Page 18 A7810 EMB HubLite –Data Acquisition HubLite
SMTP Mail HUBLite Address: The IP address of the email HUBLite on the LAN that will process and forward the email
message to the recipient.
SenderAddress: The address that will be used in the “From:” line of the email. This is helpful in identifying the source of
the alarm email message. If your SMTP mail HUBLite has junk filtering, you may be required to use a sender address that
matches a mailbox address on the SMTP mail HUBLite; check with your mail HUBLite administrator for specific details on
this issue.
Recipient address 1 (2,3): The EMB HubLite can send a copy of the alarm notice to multiple email addresses. Specify one,
two or three email addresses in the fields provided for the recipient addresses.
Modbus Framework
The Modbus Framework feature is a tool to allow the EMB HubLite to read data from any Modbus device by creating a
template in the Modbus Framework editor. The template describes the Modbus register read commands, and the conversion
required for each data point that is to be read. The Framework feature is an advanced feature of the EMB HubLite that
requires the user to be familiar with the Modbus protocol and with the Modbus register point list for the specific Modbus
device that will be used.
Wireless
The EMB HubLite and AcquiSuite systems have the ability to provide diagnostic information about R9120 ModHopper
Wireless Modbus Networks. On typical systems, an R9120 will be attached to the RS485 of the master system. The A7810
can access a ModHopper network, however it must do so through a Modbus/TCP gateway. If a ModHopper is connected in
such a way, the wireless diagnostics options will be present in the EMB HubLite. Please refer to the AcquiSuite A8812 or
A8810 user manuals for further details on the wireless diagnostic features.
Networking
Network Status
This page displays the current status of the EMB HubLite network connections. Several interfaces may be shown if both
Ethernet and ppp dialin/dialout are active at the same time. Each interface will report the ip address, number of packets sent
and received, and other details specific to the interface. For the Ethernet interface, the MAC address (HWaddr) will be
shown as well as a network collision count.
Ethernet network
eth0 Link encap:Ethernet HWaddr 00:99:99:0E:C1:CA

Note: the “lo” or Loopback interface is the internal network and is always present, “eth0” is the Ethernet segment, and
“ppp0” is the dialout or dialin connection. In addition, the current gateway and DNS HUBLite information will be shown.
These items will provide information about DHCP assigned configuration information.
Ethernet setup
The Ethernet setup page has the following options:
IPAddress: The IP address of the Ethernet interface: Default 192.168.40.50
Netmask: The netmask of the Ethernet network. Default 255.255.255.0
Gateway Address: The gateway is the routing device that moves traffic from the LAN to the internet. The default is
192.168.40.1. If you do not have an internet connection for your LAN, or you are using a crossover Ethernet cable,
leave this field blank.

Page 19 A7810 EMB HubLite –Data Acquisition HubLite
DNS 1, DNS2: These are the primary and secondary DNS HUBLites. If you are using a dialout connection, these must
be set to the DNS HUBLite provided by your dialup ISP. If you only use the EMB HubLite on a crossover cable and/or
dialin mode, you should leave these blank.
DHCP (enable/disable) If you LAN has a DHCP HUBLite, you may enable this option and remove the previous options
for IP, netmask, gateway, and DNS. Check with your LAN administrator first.
HTTP Proxy. If your LAN is connected to the internet using a sophisticated firewall, you may need to use the HTTP
proxy feature. Check with your LAN administrator first, however if you don't have a proxy set on your computer
(MSIE/Tools/Connections-tab/LAN-Settings) then you most likely don't need to configure the EMB HubLite to use a
proxy. If in doubt, leave this blank first, and try the connection test. If it fails, ask your LAN administrator about proxy
HUBLites, if any.
After changing any of the settings on this page, you will be required to reboot the EMB HubLite Use the system/status web
configuration page, or the LCD console to reboot the EMB HubLite.
Troubleshooting Ethernet Problems
After reconfiguring the Ethernet settings, if you experience problems accessing the EMB HubLite with your web browser,
check the following items.
Verify that you rebooted the EMB HubLite after making the changes to the network settings.
Use the EMB HubLite LCD console. Check the IP address and Netmask. Verify these are correct.
Verify the ethernet link/act light next to the Ethernet port is on. It should blink with activity.
Verify the network connection in your computer has the proper IP address, on the same subnet, to access the EMB
HubLite. NOTE: one common mistake is configuring the Laptop IP to the same address as the IP address of the EMB
HubLite. In order for the laptop and EMB HubLite to communicate, the IP addresses should not be identical. (see the
basic network config for suggested IP addresses. )
Use the LCD console to run the Network Status test. This will attempt a number of things including a ping query to the
gateway address. If the EMB HubLite can ping an external machine such as a gateway, the Ethernet port is most likely
connected properly. If the EMB HubLite does not use a gateway, try adding a gateway address, and make it the address
of your computer.
System Options
Status
The system status page shows the current memory and flash disk utilization values, system up-time, and load average. Also
included on this page are two buttons for Reboot and Shutdown. It is important to use the shutdown option prior to
removing power from the EMB HubLite. The LCD console will report the reboot or shutdown status.
Processes
The system process table is shown in both tree and tabular formats. The process list is useful when contacting Leviton
technical support.
Date and Time
The EMB HubLite keeps time using UTC or Universal time. All log files are recorded in UTC time as well. Timestamps
shown on the EMB HubLite local configuration pages are converted to local time for the convenience of the installer. The
date/time configuration page provides the following options
Date/time in UTC and Local time.
Date/time dropdown menus to select the current (Local) time manually.
Timezone: a drop down list of the supported timezones.
Time sync protocol: Select NTP or Rdate. Most Linux/Unix systems provide rdate, however many provide NTP as well.
Windows domain HUBLites can also provide NTP. If possible use NTP as it is a more robust protocol.
Time HUBLite: Specify the DNS name or IP address of your time HUBLite. The default “time.Leviton.com” can be used
if the EMB HubLite has a connection to the Internet. The EMB HubLite will attempt to synchronize time with the time
www.GlobalTestSupply.com
Find Quality Products Online at: [e-mail]

Page 20 A7810 EMB HubLite –Data Acquisition HubLite
HUBLite every upload session. This will ensure that the clock is checked and adjusted at a minimum of once per day.
Typically, the synchronization will align the clock to within +-1 second of the internet time source or atomic clock. You
may need to verify if your firewall will allow NTP or Rdate packets to pass through. Generally, it is better to use a local
time HUBLite if possible. The time HUBLite time.Leviton.com supports both NTP and Rdate time protocols. If you use a
GSM-connected system, you will probably need to use Rdate. NTP is blocked by many cellular service carriers.
Universal Time Is Your Friend
Log data is stored in UTC time. This allows data collection services such as BMO to collect data from multiple sites in
different time zones. If you are operating your own database system to store log data from the EMB HubLite, it is best to
store the data in UTC time in the database as well, and only convert it to local time when generating the final report or graph
for the user.
If you store data in Local time, you will have the following issues.
1) Local time is relative. Is Local the time where the EMB HubLite exists, or Local to where the data is stored? If local to
the EMB HubLite, you must shift each EMB HubLite data set depending on its location.
2) There are about 11 time zones in the US. Some observe DST, others do not. These include Alaska, Aleutian, Arizona,
Central, Eastern, Hawaii, Indiana, Michigan, Mountain, Pacific, and Samoa.
3) When converting to local time, there will be one hour of overlapping data in the fall when the time is adjusted for
Daylight Savings time. In other words, log entries run 12:45, 1:00, 1:15, 1:30, 1:45, 1:00, 1:15, 1:30, 1:45, 2:00am.
This will prevent you from sorting your data by time in your database.
4) In the spring, you will have a gap in the data from 1:59 to 3:00am. This can cause problems if you are calculating
demand values based on consumption.
5) Converting Local time to any other timezone usually involves converting it to UTC first.
Using UTC time solves these problems elegantly. The best practice is to store data in the database in UTC format and then
convert the information when generating a report for the user.
For example, if you wish to draw a graph of KW over Time, prompt the user for a date range, say Jan 1 midnight to Jan 2
midnight. Take the user specified end points and convert these times from Local time to UTC. Next, create an SQL query
using the new UTC formatted data as your select statement. ie:
SELECT * from TABLE where time > '2003-01-01 08:00:00' and time < '2003-01-02 08:00:00'
Note that the time is 8 hours ahead of local time. This example is for Pacific which is 8 hours off from UTC. This will return
a list of data points between the two specified time ranges. Next, plot the data on a graph, using the UTC times for start and
end points. Lastly, when drawing the 'time' legend on the graph, convert the values back to Local time before displaying.
For example, 2003-01-01 00:00:00 to 2003-01-02 00:00:00. Any division lines on the time axis can be handled the same
way. The advantage of using this technique is that it will properly draw a graph across DST change boundaries. The graph
axis is based on UTC time with no DST, and will not show a gap or overlap a the time of the change. The axis labeling will
be correct as well, matching the UTC times precisely.
Another way to handle the conversion is to query and convert all the returned timestamps to local time before drawing the
graph. This is useful if you do not have detailed control over the graph legend drawing process. This technique will not
properly graph across DST changes as the graph is based on local time including DST changes.
System logs
The EMB HubLite can keep several log files that report the general operation of the system, not related to the normal data
logs. These include the following:
Debug Messages: The EMB HubLite can run a “syslog” process to record more detailed information about its operations,
however this log consumes vast quantities of memory quickly, and is disabled by default. Click the “start log” button to
enable the feature. Click the “end log” button to disable. Note: when the EMB HubLite is rebooted, the debug log will be
disabled on startup.
Kernel Boot log: Startup messages about the Linux operating system startup. This log shows what hardware items were
detected and initialized.
Ftp Connection log: This log shows a list of files transferred by FTP on the EMB HubLite.
Last Data Upload log: This log file contains a report from the last data upload attempt to remote database/webHUBLites
such as BMO. This log will show if any log files are being rejected by the dabase/webHUBLite, or if the network is not
allowing a connection.
