ETHERNET
IEC 61850 and Modbus TC connection and the updating of the converter must be made using Connector3 and/or Connector4 of the
HD67736-A1 with at least a Category 5E cable. The maximum length of the cable should not exceed 100m. The cable has to conform to the
T568 norms relative to connections in cat.5 up to 100 Mbps. To connect the device to an Hub/Switch is recommended the use of a straight
cable, to connect the device to a C/ LC/other is recommended the use of a cross cable.

UPDATE DEVICE
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 I address of the device you have to use this procedure:
Turn OFF the Device;
ut Dip1 of ‘Dip-Switch A’ in ON position;
Turn ON the device
Connect the Ethernet cable;
Insert the I “192.168.2.205”;
Select which operations you want to do;
ress the “Execute update firmware” button to start the upload;
When all the operations are “OK” turn OFF the Device;
ut Dip1 of ‘Dip-Switch A’ in OFF position;
Turn ON the device.
If you know the actual I address of the device, you have to use this procedure:
Turn ON the Device with the Ethernet cable inserted;
Insert the actual I of the Converter;
Select which operations you want to do;
ress the “Execute 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 HD67736 device.
Warning:
If Fig. 7 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 C;
Try to restart the C;
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 10 make sure that you have the
administrator privileges;
In case you have to program more than one device, using the "UD Update", you
have to cancel the AR table every time you connect a new device on Ethernet. For
do this you have to launch the "Command rompt" and write the command "arp -d".
ay attention that with Windows Vista, Seven, 8, 10 you have to launch the
"Command rompt" with Administrator Rights;
ay attention at Firewall lock.
Warning:
In the case of HD67736 you have to use the software “SW67736”: www.adfweb.com\download\filefold\SW67736.zip.
