TH RN T:
The Ethernet port is used for the Modbus TCP communication and for programming the device.
The Ethernet connection must be made using Connector2 of HD67815-KNX-B2 with at least a Category 5E cable. The maximum length of the
cable should not exceed 1 m. The cable has to conform to the T568 norms relative to connections in cat.5 up to 1 Mbps. To connect the
device to an Hub/Switch is recommended the use of a straight cable, to connect the device to a PC is recommended the use of a cross cable.

UPDAT D VIC :
By pressing the “Update Device” button, it is possible to load the created Configuration into the
device; and also the Firmware, if necessary. This by using the Ethernet port.
If you don’t know the actual IP address of the device you have to use this procedure:
Turn OFF the Device;
Put Dip1 of ‘Dip-Switch A’ in ON position;
Turn ON the device
Connect the Ethernet cable;
Insert the IP “192.168.2.205”;
Select which operations you want to do;
Press the “ xecute update firmware” button to start the upload;
When all the operations are “OK” turn OFF the Device;
Put Dip1 of ‘Dip-Switch A’ in OFF position;
Turn ON the device.
If you know the actual IP address of the device, you have to use this procedure:
Turn ON the Device with the Ethernet cable inserted;
Insert the actual IP of the Converter;
Select which operations you want to do;
Press the “ xecute update firmware” button to start the upload;
When all the operations are “OK” the device automatically goes at Normal Mode.
At this point the configuration/firmware on the device is correctly updated.

Note:
When you receive the device, for the first time, you also have to update the Firmware in the HD67815 device.
Warning:
If Fig. 6 appears when you try to do the Update try these points before seeking assistance:
Try to repeat the operations for the updating;
Try with another PC;
Try to restart the PC;
Check the LAN settings;
If you are using the program inside a Virtual Machine, try to use in the main Operating
System;
If you are using Windows Seven, Vista, 8 or 1 or 11 make sure that you have the
administrator privileges;
In case you have to program more than one device, using the "UDP Update", you have to
cancel the ARP table every time you connect a new device on Ethernet. For do this you
have to launch the "Command Prompt" and write the command "arp -d". Pay attention
that with Windows Vista, Seven, 8, 1 or 11 you have to launch the "Command Prompt"
with Administrator Rights;
Pay attention at Firewall lock.
Warning:
In the case of HD67815 you have to use the software “HD67815”: www.adfweb.com\download\filefold\SW67815.zip.

KNX DIAGNOSTIC OV R MODBUS:
It is possible to save the KNX Diagnostic on Output Modbus array using the field “Diagnostic” of the section “Set Communication”.
In this case, the status of each KNX message defined in the section “KNX Access” is saved starting from the byte of the memory array
defined in the section “Set Communication”.
Each bit will represent the status of a KNX request:
If the converter receives a correct message before the timeout, the status bit is put to ‘ ’;
If the converter doesn’t receive a correct message before the timeout, the status bit is put to ‘1’.
Example:
In the section “KNX Access”, 16 KNX messages are defined. First 8 KNX messages are received in the timeout and the last 8 are not
working.
The status bits of the KNX Diagnostic on Modbus will be:
Byte x Byte x+1
bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit
1 1 1 1 1 1 1 1
where ‘x’ is the starting byte of the memory array where the KNX diagnostic is saved.
