3.3.4 Programming communication parameters
Start up the Ensite service tool and make contact with the SmartRadar LT to be configured. It is not
recommended to make a site scan, as the transmission address is still to be changed.
Therefore, to make contact with the gauge, set the address manually in the port settings. This is only
possible if the ExtendedSetup line in the ‘ENSITE.ECS’ file (in subdirectory ECS) is set to: True.
Select this window by: Set up, Port settings, and go by mouse (or with the ‘TAB‘ key) to the Baud rate.
Select 1200 baud when communicating via Enraf field bus and HART ;
®
select 19200 baud when communicating via RS-232C or RS-485.
Select the used comport on the service PC.
Then go to the line: Prefix.
When communication via 858 or 880 CIU’s, fill the desired CIU address (in the example above, it is 0).
When communicating via RS-232C / RS-485, default the CIU emulation address is disabled. Hence, delete
the part with the CIU address (delete: “ <CIU=0> “).
When communicating via HART , delete the part with the CIU address. Make transmission address 00:
®
<TA=00> to communicate with the gauge set on default address. Click on OK.
