4 About E-BACNET2-V E-BACNET2-V manual, revision B
Chapter 1 About E-BACNET2-V
E-BACNET2-V is a pre-configured converter for connecting a Corrigo E running a ventilation
application version 3.0 or later to a SCADA system. The converter has a pre-configured device id
and a fixed IP address of 192.168.92.92. Communication with Corrigo E takes place via the
PLA:ELA address 254:254. To change these settings, see chapter 3.
The Corrigo E controller is connected to the converter with the supplied cable and communicates
with the SCADA system via the Ethernet port on the converter.

Chapter 2 Wiring
Mount the converter directly on a flat surface, e.g. using a mounting screw (not included). A kit for
DIN-mounting is also available as an option. The transformer should preferably be mounted using a
cable tie.
Connect the RS485 cable marked E-CABLE-BACNET to the S0/P1 port on the converter and to the
B, A and N terminals (50, 51 and 52) on the Corrigo. Connect E-BACNET2-V to the local network
by connecting the RJ45 cable between the ETH0/LAN1 port of the converter and a network port.
The converter may also be connected directly to a computer, but this requires a crossover RJ45
cable (not included).
Connect the power supply to the converter and to the Corrigo E. Please note when wiring the supply
voltage into the converter: V + is marked while V - is entirely black.
It will take approx. one minute for the converter to start up. When the unit is ready, the Ready light
will be lit. If the Corrigo connected has the PLA:ELA address 254:254, the converter will begin
communicating. This is indicated by the S0/P1 TX and RX lights blinking. The unit is now also
available in the BACnet network.

6 Configuration E-BACNET2-V manual, revision B
Chapter 3 Configuration
All configuration takes place via the software tool E-BACNET2 configuration software for
Microsoft Windows (XP, Vista or Windows 7). The software tool is available for download from
Regin's website, www.regin.se. Once the program is started, it will scan the network for E-
BACNET2-V units. All available converters connected to the network are displayed.
Refresh
Pressing the Refresh button will update the list of converters.
Wink
Wink is a function that can be used to ensure that the correct physical converter has been selected in
the configuration tool. By selecting a converter in the list and clicking the Wink button, the LED:s
on the converter will blink and a short beep will be heard.
Edit / Change settings
Only a converter with the value BACnet = “Yes” can be edited. To edit the settings of a unit, select
it in the list of available converters and click Edit.

E-BACNET2-V manual, revision B Chapter 3 Configuration 7
This will display the following window, containing the settings that can be made:
IP
It is possible either to let the network’s DHCP server assign the converter an IP address or to assign
it a fixed IP address.
BACnet
Permits setting of:
Device ID: The device ID number of the object.
Location: Place, e.g. ”room23”.
Description: Description, e.g. ”AHU01” (air handling unit 01).
Name: The desired name of the converter. If adding a dollar sign ($) after the name, device
ID will be automatically added after it.
UDP Port. BACnet IP standard is 47808.
The checkbox “Foreign device” is used when E-BACNET2-V is to be connected to another IP
network. It is then neccessary to state the BBMD address. An example of this is when E-
BACNET2-V is stand-alone and connecting to a SCADA system over the Internet. The BBMD
address is handled by the network administrator.
Station
Used to state the PLA:ELA address for Corrigo E on the RS485 side. The Corrigo E standard
address is 254:254.
The “Debug” checkbox is used to set the converter to debug mode. This function requires a special
version of the converter, and is not normally used.
Once all settings has been made, press ”Save” in order to upload the settings to the converter.

8 Configuration E-BACNET2-V manual, revision B
Upgrading the software version of the unit
1. Power off the unit by removing the power cord.
2. Remove the cover by unscrewing the screws on each side (see photo below).
3. If a SD card is already present, eject it at the right-hand side of the unit by pressing and
then releasing the card. Mail the card back to Regin.
4. Insert the new SD card labeled “E-BACNET2-V 2.0-1-09” or later and firmly press it.
Release pressure once a click is heard.
5. Reattach the power cord and power up the E-BACNET2-V.
6. Immediately after power is turned on, the unit will beep once. The upgrade procedure has
now started.
7. Wait between 30 and 60 seconds and the unit will beep again. The procedure is now
finished, and the E-BACNET2-V unit has been upgraded.
8. If communication with the Corrigo is working, the Ready LED will be lit some 20 seconds
after the beep and the S0/P1 TX and RX LEDs will flash. If no Corrigo is connected, only
the S0/P1 TX led is flashing (about 1 Hz).
9. Power off the E-BACNET-V by removing the power cord.
10. Eject the SD card.
11. Replace the cover.
The E-BACNET2-V now has factory default IP settings, but any user configuration, such as
BACnet device ID, location, etc., is left unchanged. Run the E-BACNET2 configuration software to
change IP settings and to verify the firmware version.
