QUICK INSTALL
1. Connect the Modbus outputs of the metering devices to the Modbus terminals on
the 6-pin connec tor of the E8950. Daisy chain up to 32 metering devices to the
E8950 (provided that the total number of data points from all devices does not
exceed 1000).
2. Connect 9-30 VDC or 12-24 VAC to the power terminals on the 6-pin connector.
3. Use DIP switches S0 to S2 to set the Modbus baud rate on the E8950 to the same
rate as on all metering devices in the chain (factory default is 9600 baud).
4. Use DIP switch A7 to select the BACnet physical layer (MS/TP or IP).
5. If using BACnet MS/TP, connect the MS/TP connections to the BACnet interface.
Use DIP switches A0 to A6 to set the MAC address, and use DIP switches B0 to B3 to
set the MS/TP baud rate (factory default is 76800).
6. If using BACnet/IP, connect the E8950 to a PC using an ethernet cable and use the
GUI to set the IP address.
7. If the default network number (50) or the default Device_ID oset will cause
conicts, connect the E8950 to a PC using an ethernet cable and use the GUI to set
them appropriately.
8. Apply power to the E8950 and allow time to map all Modbus devices in the chain.
9. If the conguration is nal and will not change (no Modbus devices will be added,
removed, or changed), set the conguration mode to Normal (slide DIP switch A7
to the right) to speed future power-up cycles and prevent the auto-conguration
mechanism from overwriting when power is cycled.

(not included) on the device farthest from the E8950. An additional 120 Ω
termination and Modbus line polarization are provided internal to the
E8950.
• Connect shield to earth ground somewhere on the RS-485 bus. The shield
is not internally connected to earth ground.
• Use wire with an insulation rating sucient for the location where the
meter is installed (e.g. Belden 1120A for installation in panels with up to
60 0 VAC).
3. Connect 9-30 VDC or 12-24 VAC to the +PWR/-PWR terminals of the 6-pin
connector.
Modbus Setup
Use DIP switches S0 to S2 to set the Modbus baud rate to 9600, 19200, or 38400. The
default baud rate is 9600, because this rate is available on all the devices supported
by the E8950. If all connected devices support a faster rate, use the highest rate in
common to improve performance. Set the E8950 and all Modbus devices in the series to the same rate. Set all devices to NO parity.
INSTALLATION
The E8950 can be DIN rail mounted, using the supplied DIN rail mounting clip, or
screw-mounted directly to a wall or other at sur face using the mounting holes on
either side of the housing.

Using the GUI to Set the E8950 Internal Network Number or the Device_ID
Offset
Access the GUI according the instructions in the “Accessing the Graphical User
Interface (GUI)” section.
The home screen on the GUI shows the current values used for the oset used to
assign Device_IDs in discovery mode and the network number assigned to the
internal virtual network used by the E8950 to manage the Modbus devices attached.
Using the GUI to set up the E8950 IP address for use on your network
1. Access the GUI according the instructions in the “Accessing the Graphical User
Interface (GUI)” section. To set IP address parameters, click the button labeled
“Diagnostics and Debugging.”
The Diagnostics screen appears.
The oset used to assign Device_IDs in discovery mode is the variable labeled BN_
Node_Oset. Enter a dierent value here and click submit. The new value is rst used
at the next power-up or system restart. Valid Device_ID numbers range from 1 to
4194303. Since the numbers assigned during discovery are the sum of the Oset and
the Modbus address (which can be any value from 1-255), the Oset values entered in
the GUI must be less than 4194057.
The internal virtual network used by the E8950 to manage the Modbus devices
attached is the variable labeled BN_Network_Nr. Enter a dierent value here and
click submit. Valid network numbers range from 1 to 65534; if other values are
entered, the network number defaults to 5. The new value is rst used at the next
power-up or system restart. If using a BACnet router, it is recommended that the
router also be restarted after the E8950 has completed discovery, when the network
number is changed.
2. Have the desired IP settings ready in advance (contact the system administrator).
IP parameters for use with BACnet IP are static, not dynamic.
3. Set the IP address for use on the BACnet/IP network:
a. From the navigation tree (lef t column) on the GUI, click on Setup and then
Network Set tings to enter the Edit IP Address Settings menu.
b. Enter the desired IP address in the N1_IP_Address eld (in the format xxx.xxx.

d. If the E8950 is connected to an ethernet gateway, enter its IP address in the
Default Gateway eld.
e. Click the Update IP settings button. The E8950 will change its settings and
restart. The GUI will not connect again until the E8950 is installed on the network
that matches those settings and the new IP address is entered into a web browser
on a PC properly congured for that network.
Profile Assignment
Prole assignment is automatic. Upon power-up/reset, with the device in Discovery
mode (DIP switch S3 is to the right), each Modbus address is queried for a slave ID.
Any devices that respond with a slave ID matching a supported device are given a
unique device object and a full set of data objects to match the device.
All supported Veris meters are discovered and assigned one of the proles (see
Appendix 1) if they are connected, powered, and congured properly.
The Add/Remove/Edit buttons on the GUI can be used to alter the assignments,
but this is not recommended for general use, as the proles could be assigned to
products they do not support. If a meter is not discovered because it is not connected,
powered, or congured properly, adding the prole manually will not make it work.
Any changes to the prole assignments made manually through the GUI will be
discarded when the E8950 is power-cycled or reset in Discovery mode.
Turn on the E8950
1. Set the conguration mode switch (S3) to the Discovery
position.
2. Apply power to the E8950. It can take up to 2-3 minutes to
discover all the Modbus RTU meters, build a conguration
le, and install the device on BACnet MS/TP. Scanning begins
at address 1 and continues in numerical sequence, mapping
meters as they are discovered. To shorten this time, use
lower Modbus addresses for the meters so that they will be
discovered and mapped more quickly. After the meters at the
lower addresses are discovered, the E8950 continues scanning
the remaining addresses in the background, without aecting
operation.
BACnet Network Management – Important Steps to Avoid Conflicts
BACnet conguration uses two default settings that might need to be changed,
depending on the application.
a. Network ID number. Every logical network segment (IP subnet, MS/TP trunk, etc.)
in an entire system must have a (16-bit) network ID number that is unique from
all other BACnet networks in the enterprise. The BACnet network administrator
assigns this network ID so that no two ID numbers conict (whether using
BACnet/IP or MS/TP). Within each segment, every device is physically identied by
the combination of its 8-bit MAC address and the 16-bit network ID number.
To support multiple meters with a single E8950, the E8950 presents multiple
BACnet devices using a single (its own) MAC address. Each E8950 has its own
(internal) network ID, and it assigns a unique MAC address to each Modbus meter
attached, derived from the unique Device_IDs.
The E8950 factory default network address is 50 (decimal). If that number is
already in use in the system, assign a unique address using the graphical user
interface (GUI) on the built-in web server (this requires an ethernet connection
to a web browser; see BACnet/IP Setup section for instruc tions on changing
conguration settings using the GUI). Valid network numbers range from 1 to
65534; if other values are entered, the network number defaults to 5.
b. Device ID. Every BACnet device must have a BACnet Device_ID number that is
unique throughout the entire enterprise. Since the E8950 presents every Modbus
meter as a BACnet device, each connected meter that has a Modbus address must
have a BACnet Device_ID.
By default, each device discovered receives a Device_ID number that is the sum
of an oset value (default is 50000) and the Modbus address of the device. If
these Device_ID numbers cause a conict with existing devices in the system, or
if the system includes multiple E8950s, change the Device_ID numbers before
connecting the E8950 to the system. This can be managed one of two ways:
i. Connect to the E8950 directly (oine from the system) with the devices
(meters) connected to the E8950. After the E8950 discovers the devices
and assigns their default ID numbers, the user can choose new Device_ID
values and write these to each device using BACnet software. Subsequent
discoveries will not overwrite these values with defaults even if the E8950 is
then set to Discovery mode.
3. Optional: Lock the conguration. If no more devices will be added to or removed
from the Modbus trunk, lock the device mapping by setting the mode from
Discovery to Normal (slide DIP switch S3 to the left). This causes the E8950 to
set up the same devices at power-up, without repeating the Discovery process.
In Normal mode, the power-up time improves, but BACnet devices are created
whether the device responds or not, and new devices are not discovered.
ii. Use the GUI on the built-in web server to modify the oset value used
to calculate default Device_IDs in the discovery process (this requires an
ethernet connection to a web browser; see BACnet/IP Setup section for
instructions on changing conguration settings using the GUI). The E8950
retains this oset value and uses it to assign Device_ID numbers ever y time
power is cycled if the E8950 is in Discovery mode. Valid Device_ID numbers
range from 1 to 4194303. Since the numbers assigned during discovery are
Configuration ModeS3
Normal
Discovery
the sum of the Oset and the Modbus address (which can be any value from
1-255), any Oset values entered in the GUI must be less than 4194057.
Determine the best mode for the application. Discovery mode queries and rediscovers devices each time the E8950 is power-cycled or reset, so use this mode
when you anticipate adding, removing, or changing Modbus devices. Normal
mode creates the same set of BACnet device objects when the E8950 is powercycled or reset, even if objects change, are removed, or cease to communicate.
Power-up time is faster in Normal mode.

General Programming Information
The E8950, in Discovery mode, queries each Modbus address, from 1 to 247 for a slave
ID. For each address queried, if a meter responds with a slave_ID that matches those
supported by the E8950, a BACnet device object and a full set of data objects are
created (see Appendix 1).
The initial Object_Identier (Device_ID) property value of each device objec t
discovered is the sum of the Device_ID oset programmed into the E8950 and the
Modbus address of the meter. The factory default value of the oset is 50000; use
the GUI to change this value. The new value will be applied the next time the E8950
is power cycled or reset. Once a device’s Object_Identier is overwritten, changes
to the ID Oset will no longer aect that Object_Identier, even in Discovery mode.
Make further changes to the value by writing the Object_Identier property.
The default Object_Name property value of each device object is an abbreviated
name of the meter series discovered with an underscore and the Modbus address of
the meter appended to it. The Object_Name is a writable property. Once a device’s
Object_Name is overwritten, the Object_Name will not rever t to the initial default,
even in Discovery mode. Make fur ther changes to the value by writing the Object_
name property.
The default description property value of each device object is the rst 40 characters
of the Modbus slave ID returned by the meter discovered. The description is not a
writable property.
The E8950 supports Subscribe_COV, with default COV increment values assigned
as shown in the data object tables (see Appendix for value tables for each meter).
If these values are not appropriate for a specic application, write them as needed
when they are subscribed. On subsequent power c ycles, no subscriptions are active
and the COV increments return to their default values.
With few exceptions, any data values written to AV objects are accepted (without
error) by the data object and passed through to the corresponding Modbus register.
There is no direct indication via the BACnet protocol if invalid values are rejected.
After an invalid value is written to the Present_Value of an AV, subsequent reads
of that propert y return the new (invalid) value until the next time the E8950 scans
and updates the AV objects (this may take several seconds, depending on the overall
conguration and timing of the scan sequence). The tables in Appendix 1 specify valid
values for AV objects of each supported model.

yields a potential transformer ratio of 2:1). The default is
100 (1.00:1), which is with no PT attached. Set this value
before setting the system voltage (below)
type 10 (AV2), which is line to neutral.
The meter uses this value to calculate the full scale power
for the pulse conguration (below), and as full scale for
phase loss (AV8). The meter will refuse voltages outside the

(in object AV6). Default is 10 (10%). Any phase (as
congured in AV2) whose level drops below this threshold
triggers a Phase Loss alert. E.g., if the System voltage is set
to 480 V L-L, the nominal L-N voltage for each phase should
be 277 V. When the threshold is set to 10%, if any phase
drops below 27.7 V, or if any L-L voltage drops below 48 V
the corresponding phase loss alarm bit is true.

type (40 in object AV2), both Line to Neutral and Line to
Line voltages are tested. In a 3-phase Δ System type (31 in
object AV2), only Line to Line voltages are examined. In a
single split-phase (2 + N) system type (12 in object AV2),
just the line to neutral voltage are compared. E.g., if the
System Type is 40 (3-phase with Neutral) and the Phase
Loss Imbalance Threshold is 25%, a Phase Imbalance is
indicated when the L-L voltage between any t wo phases
drops to less than 75% of the L-L voltage between any
other two phases or when the L-N voltage of any phase
drops to less than 75% of the L-N voltage of any other
phase.

Sub-Interval Length (in object AV11) is set to 0 (sync-tocomms mode), the value of this object is ignored.
comms mode, which allows manual triggering of demand
intervals and the logging of another Trend_Log record, set
this value to 0 and write 21211 to the reset register (object
AV1) each time the sub-interval must be externally reset.
Default is 90000 (15 minutes). This variable is tied directly
to the Log_Interval property of all three Trend_Log objects
(their value is always the same as this one). Changing any
of these four properties
changes all of them.

type (40 in object AV2), both Line to Neutral and Line to Line
voltages are tested. In a 3-phase Δ System type (31 in object
AV2), only Line to Line voltages are examined. In a single
split-phase (2 + N) system type (12 in object AV2), just the
line to neutral voltage are compared. E.g., if the System Type
is 40 (3-phase with Neutral) and the Phase Loss Imbalance
Threshold is 25%, a Phase Imbalance is indicated when the
L-L voltage between any two phases drops to less than 75%
of the L-L voltage between any other two phases or when
the L-N voltage of any phase drops to less than 75% of the
L-N voltage of any other phase.

The method of demand calculation is set as follows:
0 = Sliding Block. Like rolling block, but with a subinterval of
15 seconds; used for Demand Intervals ≤ 15 minutes, or 60
seconds for intervals > 15 minutes
1 = Block. Fixed block with no sub-intervals.

This value must divide evenly into the Block Demand Interval

For example, if the Demand Block Interval is 15 minutes, valid

then there will be 3 subintervals of 5 minutes each.

E30A042 and E30A142 Branch Circuit Power Meter
The E30A042 and E30A142 meters have 783 data objects per Modbus address and operate at 9600, 19200, or 38400 baud. These meters monitor current, power, demand, and
energy on 42 branch circuits and 4 main circuits (up to 3 phases, plus neutral) and use only one Modbus address.
Due to the capacity limitation of 1000 BACnet data points, the E30Ax84 models and the E31Axxx models are not fully suppor ted. If these produc ts are discovered by the E8950,
they will be automatically mapped to the E30Bxx x prole, which supports a more limited data set.
AV4-AV45 are not writable on E30xxxx solid-core models because the CT size is xed (at 100 A). Other values written revert to 100 A the nex t time the meter is scanned.

INSTALLATION GUIDE
E30Bxxx/Cxxx and E31Bxxx/Cxxx Branch Circuit Meters
The E3xBxxx/Cxxx meters have 446 data objects per Modbus address and operate at 9600, 19200 or 38400 baud. These meters monitor current on 42 branch circuits and 4
main circuits (up to 3 phases, plus neutral) for each Modbus address. The E3xBxxx models also monitor power, demand, and energy on the main channels (not the branches).
The E30Bx42/Cx42 models have one Modbus address and support only 42 branch channels (plus main channels). The E30Bx84/Cx84 models and all E31Bxxx/Cxxx models have
two Modbus addresses and support up to 84 branch channels and two sets of main channels. On E3xCxxx models, some of the data objects are not used and will return QNAN
when their Present_Value is read.
AV4-AV45 are not writable on E30Bxxx/E30Cxxx solid-core models because the CT size is xed (at 100 A). Other values written revert to 100 A the next time the meter is
scanned. AV4-AV45 are writable on E31Bxxx/E31Cxxx split-core models.
