1DESCRIPTION OF THE DEVICE
This section describes the most important features of the device in relation to communications.
1.1 INTRODUCTION
The EPS-120-5192 and EPS-200-5193 chargers have WEB services that can be accessed via an
RJ45/Ethernet port.
The device has two microcontrollers: one dedicated exclusively to the charger control and the other one to
the communications control. This fact means that each one has its own firmware.
The diagram shown in Figure 1.1 shows the internal flow of information in the charger.
1.2 PROTOCOLS SUPPORTED
Table 1.1 shows the communications protocols supported and the device functionalities to which they are
related.

1.3 PHYSICAL INTERFACE
To perform any of the actions specified in this manual, it will be necessary to have physical access to the
device. The physical interface is a single button, as can be seen in Figure 1.2, labelled "Battery
Reconnection", located near the Ethernet port.
Figure 1.2 - Physical Interface
This interface will be useful for allowing access to the device in local mode. This point is fully specified in
section 0 Local Access.

2WEB ACCESS
This section specifies the steps to follow to enable web access to the device.
2.1 ETHERNET CONNECTION
An active Ethernet connection must be available in order for there to be any web access to the device. To
do so, the device must be connected using an Ethernet cat5e cable or higher with an RJ45 connector. At
the other end of the cable, a device will be connected that is configured within the same IP range as the
device.
2.2 WEB CONNECTION
The web access to the device is provided through a PC, using one of the supported browsers specified in
Table 1.2.
Table 1.1 - Supported browsers
Browser Version
Mozilla Firefox 26.0 or higher
Google Chrome 29.0 or higher
Internet Explorer 11.0 or higher
In order to gain access, the IP address of the device must be entered in the address bar. As specified in
Table 1.3, this IP address can be assigned in 3 different ways.

2.3 USER TYPE
There are two user types that are associated with the editing modes that the charger allows. These are
defined by accessing the LDAP server. Table 1.4 is an overview of the available modes and allowed functions.

2.4 LOCAL ACCESS
The device has a method for accessing web services by making a direct (local) connection to it.
This mode allows the same actions to be performed as are allowed when accessing remotely, but with the
following characteristics:
∗No need to have access to an LDAP server to authenticate it
∗Always accessed with the same IP address (100.0.0.1)
∗Username/password relationship is predefined

To access this mode, it is necessary to use a PC and follow the steps below:
1. Check that the device is switched on ("Device ON" LED activated)
2. Press and hold the "Battery Reconnection" button for more than 10 seconds
3. Check that all the LEDs have started blinking
The recommended configuration for the PC is specified in Table 1.5.

Parameter Value
IP 100.0.0.2
Subnet mask 255.255.255.0
Browser See Table 1.2
The maximum time that this mode remains active is 20 minutes, however, it is necessary to exit this mode
once the desired actions have been performed.
In local mode, it will be accessed with the usernames specified in Table 1.6. One of them allows access in
viewer mode and the other in administration mode.

To exit this mode, it is necessary to follow the steps below:
1. Check that all the LEDs are blinking
2. Press and hold the "Battery Reconnection" button for more than 10 seconds
3. Verify that all LEDs have stopped blinking and are illuminated for normal operation

3.3 AUTHENTICATION
The first time you connect to an EPS-120-5192 or EPS-200-5193, you will get an authentication window like
the one shown in Figure 2.2.
You must enter the username associated with the mode you want to access, and the correct password.
Figure 2.2 - Authentication
If the username and password entered are valid, a menu like the one in Figure 2.3 will be displayed, in which
you will be able to select the desired and/or allowed access mode.

The device limits the maximum number of users authenticated at the same time for each mode, as specified
in Table 2.2. If this limit is exceeded, you will be asked if you want to disconnect any of the previously
authenticated users.

3.4 SUPERVISION
The following section describes the web pages that can be accessed from the Supervision menu and the
functions that are available on these pages.
3.4.1 SYNOPTIC
The Synoptic page (Figure 2.4) shows the most important information on the current status of the device.
The main element is a schematic representation of the different components that make up the device (AC
Input, Battery and Output) and their interconnection.
The lines connecting the components have 2 states:
∗Green: There is connectivity, and it shows the direction of the electrical current in that section
∗Grey: No power and/or the section has been disconnected
In section 4.1 Synoptic Scenarios of the annex, different screenshots have been added to show the different
states of the connection lines, depending on the status of the device.
The diagram also shows the states of the LEDs as they are on the device itself, and the state of the alarm
relays. Red indicates that the relay is closed.

The header will have the following fields:
•State: Shows the state that the device is in (see Table 2.3)
•System date: This is the date the system is using
•NTP status: Indicates whether or not the device has synchronized the date and time with an NTP
server.
The possible values are ACTIVE / DISCONNECTED.
•Daylight saving: Indicates whether or not the device has the daylight saving time setting activated.
The possible values are ACTIVE / DISCONNECTED.
•Battery identifier: Value configured as battery identifier.
•Alarm activated: Number of active alarms.

Each alarm can be in two states:
∗Green: The alarm is not activated
∗Red: The alarm is activated
The alarms shown on this page are in turn grouped into 4 blocks. Each of these blocks can be in two different
states:
∗Green: All the alarms in the block are inactive
∗Red: One of the alarms in the block is active
In point 4.2 Alarm Scenarios of the appendix, different examples are shown depending on the active
alarms.
