Overview
Leviton's EMHSP and EMHXD Energy
Management Hub is a family of data
acquisition systems which provides owners
and managers of commercial and industrial
facilities with a cost-effective means of
gathering crucial information in a
timely manner.
The footprint and industrial temperature range
makes this a perfect solution for embedded
applications. Reduce development time
and speed up integration by collecting and
distributing energy and sensor data directly
from your equipment.

Installation Checklist
Hardware:
• EMHSP and EMHXD Data Acquisition Server (DAS)
• Laptop (not provided) with one RJ45 port (required for LAN or direct
laptop-to-DAS connection)
• Ethernet Cat 5 or better ethernet cable (not provided)
• Power Supply 24VDC, 500mA or greater (not provided)
Optional hardware:
• Additional Modbus TM Devices
• 2 wire, twisted pair with shield for Modbus/RS485 connection
(Belden TM 1120A or equivalent)
• Termination resistors (120 ohm) for long RS485 runs over 200 ft
Mounting
DIN Rail: The EMHSP and EMHXD is designed with integrated DIN rail mounting clips for a
standard 35 mm DIN rail. The integrated clips on the back of the enclosure will snap directly
on the rail.
Mounting Tabs: The enclosure provides mounting tabs in each corner of the enclosure.
Use the appropriate type #6 or smaller screw to attach the unit to the mounting surface.

Mounting Installation
1.
Unpack materials.
2.
Mount the DAS using either the DIN rail mount, or with screws through the mounting tabs.
3.
Optional: Connect the Modbus network loop as shown in the diagram. Follow the
manufacturer's instructions for installing and powering the Modbus devices.
4.
Connect a PC to the DAS using a Cat 5 or better ethernet cable.
a. ENET 1 should be the "upstream" connection to the Internet. Connect it to your
rewall/router or Ethernet modem.
b. ENET 2 should be the "downstream" connection, for your PC and for Ethernet meters
and devices.
5.
Supply +24VDC to the DAS. Once power is applied, the Status LED will immediately turn
on and the LCD will show a series of progress messages as the system boots.
6.
Decide type of connection:
a. DHCP Mode (DHCP is the default and is recommended).
b. Static IP Mode.

DHCP Enabled Mode
Con rm the DAS is properly connected to the computer or a LAN, and that both are
powered ON.
1.
Con rm that DHCP is enabled on the computer. For most computers, this is the
default setting.
2.
From the device front panel, navigate to the Quick Start menu. The rst screen in the
Quick Start will display the IP addresses for active Ethernet connections. Be sure to use
the IP address for the correct Ethernet port, if both ports are connected. The device must
be connected to the same network that the PC is connected to.
NOTE: If Enet 1: is not set to DHCP go to "Front Panel Setup - DHCP Mode"
3.
Open a browser and type the IP address, as shown on the LCD display of the EMHXD, in
the address bar.
4.
This will open the web browser interface of the DAS.
5.
At initial setup, a password must be created. Select "Password Setup" to create the admin
user password.
6.
Enter the desired admin user password in both boxes and select "Apply."
7.
A message con rming that the password was successfully set will display. Select the link
below it to proceed to the login screen.
