Expert Power Meter
1. Description
Expert Power Meter
(
EPM
) is a 19“ device, that makes it pos-
sible to measure energy consumption for two channels.
It operates as an energy consumption meter and measures cur-
rent, voltage and active/apparent power. All of these information
can be requested by Ethernet or directly at the device.
The energy consumption meter measures the spent energy on
two counters, one shows the total energy consumption since
starting-up
EPM
, the other counter is resettable.

Con guration by using
Gbl_Conf.exe
To change the TCP/IP settings of your
EPM
you
need the tool
Gbl_Conf.exe
. This tool can be found on the CD-ROM or is free
to download from our website
www.gude.info
.
Addi
tionally you can update the  rmware, deactivate passwords
and IP ACL and set
EPM
back to default settings, when you use
this tool (see more in chapter 5).
To check the current con guration, please
choose your
EPM
from the list in the left window.
If the displayed IP address is the default IP address
(192.168.0.2)
no DHCP server is located in your network or it was not possible
to provide a free IP address to
EPM
.
In this case, activate the bootloader mode of
EPM
and enter a
valid IP address and the network mask. Save your con guration:

3. Con guration
3.1 Automatic con guration by using DHCP
After power-up,
EPM
looks for a DHCP
server in the network
and requests a free IP address from this server.
Please check at your DHCP server, which IP address was
provided to
EPM
and make sure, that this IP address will be
reserved.

and Login.
To enter the con guration menu, click on „Con guration“ on the
upper left side of the screen.

EPM
uses this name to connect with
DHCP server.
Special signs may destabilize
your network.
IP Address
Here you can change the IP ad-
dress of
EPM
.
Netmask
Here you can change the netmask of
EPM
.
Gateway
Here you can change the standard gateway of
EPM
.
Use DHCP
Here you can set, if
EPM
shall get its TCP/IP settings directly from
your DHCP server. If DHCP is activated,
EPM
proves if a DHCP
server is active inside of your LAN. Then
EPM
requests TCP/IP
settings from this server. If there is no DHCP server inside of your
network, we recommend to deactivate this function.

.
If you locked yourself out by mis-
take, please activate the boot

and deactivate IP ACL.
If IP ACL is active,
DHCP and SNMP only work, if all neces-
sary servers and clients are registered in this List.

Con guration - HTTP
HTTP Port
Here you can enter the HTTP port number, if necessary. Pos-
sible numbers are 1 ... 65534 (standard: 80). To get access to
EPM
, you have to enter the port number behind the IP address
of
EPM
:
http://192.168.0.2:1720/
Require HTTP Password
If it is required, you can activate a
password request. Then you have
to enter two passwords, one ad-
ministrator password and one user
password. Each password has a
maximum length of 15 signs. If an
administrator password is active
you can log in to change settings
only with this password. User are
able to log in with the user pass-
word to see the monitor informa-
tion.
If you have forgotten your password, activate the bootloader
mode of
EPM
, start
Gbl_Conf.exe
and deactivate the password
request.

3.4 IP Access Control List
IP Access Control List (IP ACL) acts as an IP  lter for
EPM
.
Wether it is active hosts and subnets only can contact
EPM
, if
their IP adresses are stated in this IP ACL.
e.g.:
„http://192.168.0.1“
or
„http://192.168.0.1“ or „http://192.168.0.1“
„http://192.168.0.1/24“
If you locked yourself out by mistake, please activate the boot-
loader mode of
EPM
, start
Gbl_Conf.exe
and deactivate IP
ACL.
You can  nd more information about con guration of IP ACL in
chapter 3.3 or have a look at
www.gude.info/wiki
.
3.5 SNMP
To get detailed status information of
EPM
SNMP can be used.
SNMP communicates via UDP (port 161) with
EPM
:
Supported SNMP commands:
- SNMPGET:
request status information
- SNMPGETNEXT:
request the next status information
You will need a Network Management System, e.g. HP-Open
View, OpenNMS, Nagios etc., or the command line tools of NET-
SNMP to request information of
EPM
via SNMP.
SNMP Communities
SNMP authenti es requests by so called communities.
The public community has to be added to SNMP-read-requests
and the private community to SNMP write requests. You can see
the SNMP communites like read/write passwords. SNMP v1 and
v2 transmit the communities without encryption. Therefore it is
simple to spy out these communities. We recommend to use a
DMZ or IP ACL.

13
Expert Power Meter
3.6 Syslog
Syslog messages are simple text messages transmitted to a
syslog server using UDP.
Linux OS regularly have a syslog daemon installed, e.g. sys-
log-ng. For Windows there are some freeware tools available.
On following events,
EPM
will send a syslog message:
- Booting up
- Switching off
- Activation/deactivation of syslog
- Load more than 10 A, load again less than 10 A
You can  nd more information about con guration of Syslog in
chapter 3.3 or have a look at
www.gude.info/wiki
.
MIBs
All information, that can be requested or changed, the so
called
„Managed Objects“, are descripted in „Management Information
Bases“ (MIBs).
There are three MIBs, which can be requested from
EPM
:
„system“, „interface“ and „gadsepm“
„system“ and „interface“ are standardised MIBs (MIB-II).
„gadsepm“ (GUDEADS-EPM-MIB=“gadsepm“) was created
especially for
EPM
.
At least, there are so called Object Identi ers (OID) subordi-
nated to those three structures. An OID describes the location of
an information inside a MIB.
You can  nd more information about con guration of SNMP in
chapter 3.3 or have a look at
www.gude.info/wiki
.
