Hardware Installation
Step 1 - Unpack materials: Remove all materials from shipping box and verify all required components are available
Step 2 - Mount the Energy Monitoring Hub on the wall or other appropriate location.
Shop for Power Metering products online at: 1.800.561.8187
www.PowerMeterStore.ca

Step 3 –(optional) Connect any analog or pulse output sensors you may have. For Analog sensors, 0-10V or 4-20mA sensor
types are allowed. The combined power consumption of all the analog sensors attached to the Energy Monitoring Hub must
not exceed 200mA. If more current is required, use an external power supply as shown in the wiring diagram for each input
type later in this section.
Step 4 (optional) - Connect the Modbus network loop as shown in the wiring diagram. Follow the manufacturer‟s
instructions for installing and powering the Modbus devices. Verify that the Modbus address settings are unique for each
device (i.e., no two devices with the same address) and power up the device. Connect each device in the chain by “daisy-
chaining” the devices together. Observe + and - polarity on the Modbus devices.
Low Voltage analog, pulse, and RS485 wiring that enter electrical panels must have a minimum insulation rating that
exceeds the voltage inside the panel. In addition, other regulations may apply; consult the building codes in your area prior
to installation.
The RS485 port on the A8812 has a built in terminator. A 150 ohm termination resistor should be placed at the other end of
the RS485 loop, between the + and –wires.
Note: Some Modbus devices do not use the same label notation as the Energy Monitoring Hub.
The Energy Monitoring Hub A8812 internal IO module (Analog and pulse inputs) uses Modbus address 250, and will show
up in the Modbus device count as a single Modbus device. Additional analog or pulse input IO modules may be added to the
Modbus loop as needed.

Step 5 - Power-up and diagnostics: Attach the power supply to the power input jack on the Energy Monitoring Hub, and
plug the power brick into a wall outlet. The power brick should be in a location that is accessible for connection and
disconnection. After power is applied, the green “Alive” light in the upper right of the Energy Monitoring Hub 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):
AcquiSuite Ready
192.168.40.50
This indicates that the Energy Monitoring Hub 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 cord is plugged in. 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 A8812 has been powered up for a minute, the green Alive LED
should blink slowly once per second during normal operation.
Modbus TX/RX: The Modbus TX and RX LEDs blink to indicate data on the RS485/Modbus loop. The
RX led blinks only when data is received by the Energy Monitoring Hub
Modem RTS: the modem is being monitored or operated by the Energy Monitoring Hub, off when the
modem is idle. This LED will be on when a dialout call is in progress, or when dial in is enabled and
waiting for an inbound call.
Modem CD: the modem has a carrier connection to a remote system.
Modem TX/RX: data is being sent or received on the modem.
Alive: blinks once per second while the system is operating correctly.
Alarm: blinks to indicate a problem.
Inputs 1-8: in pulse or status mode, the LED is on when contacts are closed. In analog 4-20mA and 0-
10V mode, the led blinks quickly (2 Hz) to indicate an over-range alarm error. In 4-20mA mode when the
input current is less than 4mA, or in resistance mode where the input resistance is above 10Mohm, the led
will blink a pattern (blink, blink, off) to indicate a broken wire alarm.
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 Energy Monitoring Hub.
RF TX / RF RX: If the A8812 has a built-in ModHopper option with an on-board radio, the RF LEDs
will blink showing transmit and receive packets.
Step 6 - Verify connected devices: To verify that the Modbus devices are installed and reporting correctly, use the Modbus
status utility on the Energy Monitoring Hub server. To do this test, follow these steps:
A. Press and release the menu (top) button on the Energy Monitoring Hub. The following will appear on the
LCD display:
[Main Menu]
TCP/IP Config
B. Press the menu (top) button several more times until the LCD display shows the following message:
[Main Menu]
Modbus Status
C. Press the select (bottom) button on the server and the unit will begin the diagnosis of the Modbus loop.
After the check is completed, the unit will display the following message:
X devices OK
X fail, X new
D. Verify that the number of devices located by the server (the total of OK, fail and new) matches the number
of devices actually installed and connected. For a first time installation, all devices should appear as “new”.
The Energy Monitoring Hub A8812 Internal IO (pulse and analog inputs) appear as one device in this list.
Shop for Power Metering products online at: 1.800.561.8187
www.PowerMeterStore.ca

(Note: A “device” is the Modbus connected device, not necessarily the sensor. For example, an A8923-4 I/O
module with 4 sensors connected is only one Modbus device, not four.) For further information on the LCD
console, please review the console section of this manual.
E. The Energy Monitoring Hub completes a background scan for new Modbus devices every 2-5 minutes.
Increasing the RS485 Modbus timeout may increase the time required to detect new devices. If the Modbus
devices are connected after the server is booted up, the devices may not appear on the screen for several
minutes. In the worst case, allow up to 5 minutes for the Energy Monitoring Hub to locate all the connected
devices.
F. If all devices are reporting properly, it is now time to connect the server to the network or phone line for
remote reporting and configuration.
Basic Network Configuration
Step 1 - Determine the IP addressing needs: The IP address of the Energy Monitoring Hub server 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 “hard-coded” into the
Energy Monitoring Hub; or
Dynamic Host Configuration Protocol (DHCP) address - this process assigns an IP address dynamically to the
Energy Monitoring Hub when it is connected to the network from a host DHCP server; or
Direct connection between the Energy Monitoring Hub and a single temporary computer such as a laptop. (primary
connection will be dial in 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 IP Address

Direct Connection to Laptop
IP address: ___.___.___.___
Netmask: ___.___.___.___

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 server displays the start screen:
AcquiSuite Ready
192.168.40.50
If this screen does not appear on the LCD display, press and hold the menu (top) button on the server 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 (top) button once to get the TCP/IP configuration menu
[Main Menu]
TCP/IP Config
B. Press the select (bottom) button twice to get the IP config menu:
