1. General description.
The RS485-ETHERNET interface is intended for cooperation with PSUs of the EN54C-LCD series.
The PowerSecurity software enables remote monitoring of parameters through a cyclical preview of the current
status of the power supply, reading the event log and diagrams of currents and voltages and performing remote
battery test.
Interface is a device used to convert signals between RS485 bus and Wi-Fi network. For proper operation,
unit requires an external power supply in range of 10÷30 V DC e.g. drawn from a PSU of EN54C series.
Unit is mounted in a hermetic enclosure protecting against adverse environmental conditions.
Fig.1. Schematic diagram of Ethernet network communication.
The network topology is based on an Ethernet switch (e.g. switch, router) to which subsequent segments of
power supplies are connected (connected in the RS485 bus) via the RS485-Ethernet interface. Each interface has
a static IP address. The communication between a PC and an end PSU is effected through entering of the IP
address of the interface, the address of the PSU in the RS485 bus, and the number of the port in which the
communication takes place. An interface may support a maximum of 247 PSUs on one RS485 bus.

3. Installation.
3.1 Basic guidelines.
When installing the INTRE-C interface, please follow the general rules that will help to avoid
electromagnetic interferences and incorrect operation of the device:
- supply the interface with the power source of low ripple voltage
- power cable should be as short as possible
- signal beams should be led at a minimum distance of 50 cm from each other, while the intersections between
them should be done at an angle of 90°
- interface installation site should be located at a considerable distance from the equipment generating large
impulse disturbances, such as inverters, contactors, relays
4. Connection to RS485 bus.
The RS485-ETHERNET interface is connected to the RS485 bus via the „RS485” connector. Connect the
wires of the RS485 bus to the A+, B- terminals of the connector. They are marked and connected the same way as
the rest of devices (A+ to A+, B- to B-).
Use a twisted-pair cable as a transmission wire of the RS485 bus. The „point-to-point” topology is
recommended, while the „star” topology should be avoided. If the wires are long enough, it is recommended to use
shielded cables to avoid errors during the communication and to lower the susceptibility to noise and radio
interference. It is recommended to mount the terminal resistors at the ends of the bus with a resistance close to the
impedance of the used cable, which is 120 Ohm.
4.1 Connection to the Ethernet networ.
The connection of the RS485-ETHERNET interface to the Ethernet network should to be made with a
U/UTP twisted-pair cable, of min. 5 category, ending with RJ45 plugs, connected according to colour and
accordingly to the EIA/TIA 568B standard. If the dedicated location shows a high level of electromagnetic
interference, use a F/UTP or S/UTP shielded cable, thereby substantially reducing penetration of electromagnetic
interference.
The connection of the interface to the Ethernet network uses a cable with RJ45 plugs, non-interlaced.

5. Installation of the interface.
1. Lead the cable of the RS485 bus through the cable gland and the appropriate hole in the enclosure and then
connect to the RS485 connector of the interface. The A+, B- cables should be connected the same way as the
rest of devices (A+ to A+, B- to B-) In the case of shielded wires, the shield should be connected to the SG
signal ground terminal.
2. Optionally, mount the 120 Ohm terminal resistors at the end of the RS485 bus.
3. Lead the Ethernet cable through the cable gland and the appropriate hole in the enclosure and then clamp the
RJ45 plug. Next, plug the cable in the RJ45 socket of the interface. Plug the other end of the twisted pair in the
RJ45 socket of the router, usually marked as „LAN”.
4. Lead the power supply cable through the cable duct and the appropriate hole in the enclosure and then
connect it to the ‘Power’ power supply connector. The power source should supply a voltage in the range of
10÷30 V D e.g. drawn from a PSU of the EN54C series. The best solution is to use a PSU that is plugged into
the RS485 bus and located close to the interface.

6. „PowerSecurity” web application.
The PowerSecurity web application has been embedded in the INTE-C and INTRE-C communication
interfaces. The programme is a website uploaded from an embedded WWW server which is loaded upon entering
the IP address in the web browser window..
Upon loading the PowerSecurity application, access is gained to the preview of the status of the PSU
connected with an INTE-C interface, or to the preview of all PSUs in the RS485 bus in case of an INTRE-C
interface.
From the WWW browser level, the current status of the PSU can be checked, with preview of such
parameters as output voltages, presence of 230 V supply, or resistance of the battery circuit.
Moreover, the application has an option of interface configuration for the function of remote alerting through email
notification including information on the status of the PSU in case of occurrence of specific events.
4.1 Configuring the connection.
To activate remote communication with the PSU, first setup the connection between the PSU and the
interface, followed by preliminary configuration of the Ethernet INTRE-C module.
The IP address of the module should be entered in the web browser window. The default value is
IP=192.168.1.100.
If the entered IP address is correct, the module login page will be loaded on the browser screen.
Fig. 4. Ethernet module login page.
If the browser does not display the page above, check the Ethernet configuration.
In particular, check the following:
- are the addresses of the network adapters of the computer and router found in the same subnet,
i.e. within the range 192.168.1.0 –192.168.1.255
- addresses of the network adapters of the computer and router must be different from the address
of the interface, i.e. 192.168.1.100
Appropriate configuration may be performed in the network adapter settings.

Upon loading of the login page, choose the installer’s name and enter the access password.
The default settings are:
name = „installer’s”
Password: = „admin”.
It is recommended to change the installer’s name and the password upon the first logging.
An Ethernet module enables restoration of default logging values in case they are lost. To this end, open
the PSU casing so as to gain access to the module installed inside. Then locate the communication module and
press „INIT” for approx. 5 secs.
Fig. 6. View of the Ethernet module.
The following default parameters will be restored:
IP address: 192.168.1.100
Installer’s level:
Name: „Instalator”
Password:: „admin”
User’s level:
Name: „Użytkownik”
Password:: „user”

4.2 Device’s
Upon a correctly conducted logging operation, the PowerSecurity web application with visible available
devices will be loaded.
During the first startup of the PowerSecurity application, the field of PSUs will be empty,
despite the physical connection being established. For the PSU to appear in this field, start the
detection procedure –see section „INTRE-C Interface –Detection”.
Fig. 7. View of the „Devices” tab.
The information window consists of three essential components: a menu bar containing the list of tabs, a
communication interface field, and the PSU field.
In the picture above, the list of tabs only features two items: „Devices” and „Installer”. This list has many
more functions which will appear dynamically, only upon selection of one device: an interface or a PSU.
In order to gain access to the device (interface or PSU) configuration, select it with the cursor in the
browser window or point on the „Devices” tab and make a selection from a drop-down list.
