It is possible to reduce the number of units that will be
controlled through the Bacnet gateway, or to change the
IP address of the gateway and of the units as well.
- Download from www.lemmens.com website
the configuration 2 files.
- Installation package of "Compositor SW67673”.
- Package “Install BACnet Config”.
- Install first the software "Compositor SW67673”.
- Extract the package “Install BACnet Config” in
the Project folder of Compositor.
5.2 Custom configuration
Example of installation:
Start BACnet config.exe:
With the interface it is possible to:
o Remove a unit or add a unit
o Change the gateway IP configuration
o Change the gateway communication port
o Change the last number of the IP address of the
units on the corresponding row inside the table.
N.B.: for the units, only the last number of the IP address
can be changed since it must be within the same range of
the gateway IP address.
o Save the configuration
o Open a previously saved configuration
5.3 Upload configuration
The module has a default configuration loaded, so there
should be no need to make any changes if the default
configuration can be used.
Procedure to change the configuration of the module:
1. Set up first the computer used for downloading in
order to be able to communicate with the gateway:
Set IP address of the computer to 192.168.1.10.
The net mask will be 255.255.255.0.
The gateway is not used so 0.0.0.0.

2. Press the button “Open Configuration” (on Step 1 row)
and then choose the folder corresponding to the desired
project for downloading.
3. Press the button “Update Device” (step 5). The fol-
lowing dialog box will appear where there is no need to
change anything (the IP address may be different from
the picture, according to the one configured in the pro-
ject).
4. Press the button “Ping”, then the text “Device Found”
will appear:
5. Press the button “Next”, the following dialog box will
appear where only “Configuration” and “Read the con-
figuration when finish” must be checked:
6. Press the button “Execute update firmware”.
7. The status update window will appear to show the
evolution of the downloading.
8. If error message, do the verifications as described in
step 9:

9. Check that the firewall allows the update software to
go through it. Here is an example with Windows 10 ©:
10. Try to repeat the operations for the updating;
Try to restart the PC;
If using Windows Seven or Vista,7, 8 or 10, make sure to
have the administrator privileges;
Check the LAN settings.
Try with another PC.
5.4 Resetting the IP address:
The gateway comes with default IP address 192.168.1.9.
If this address has been changed later on and the address
is not known anymore, follows this procedure to set the
back the factory address.
1. Turn off the Device;
2. Put Dip2 of ‘Dip-Switch A’ at ON position (Fig.1)
3. Turn on the device
4. Connect the Ethernet cable;
5. Insert the IP “192.168.2.205”;
6. Press the “Ping” button, must appear “Device Found!”
7. Press the “Next” button;
8. Check all operations;
9. Press the “Execute update firmware” button to start
the upload;
10. When all the operations are “OK” turn off the Device;
11. Put Dip2 of ‘Dip-Switch A’ at OFF position (Fig.2)
12. Turn on the device.
13. Upload a configuration (see 5.2).
