Configuration of the data transmission: Humphrey Field Analyzer 3 (Model 8xx)

IMPORTANT: Preliminary notes

Data is transferred from the HFA3 to PeriData using a FILE. The HFA3 exports the file to a defined folder. PeriData reads the file from this folder and then deletes it afterwards. There are 2 important details to note here:

File format

The HFA3 is able to export different types (formats) of DICOM files. All of them have the similar file extension .dcm, but differ internally. The difference is only noted when the file is read/opened. Only the format DICOM-OPV contains utilisable visual field data and is suitable for PeriData.

Non-fitting DICOM formats: DICOM-EPDF (embedded PDF) is a PDF wrapped into a DICOM container. HFA3 Format is a proprietory Zeiss format with unpublished structure. If PeriData finds a not-fitting DICOM file in the import folder, it gives a notification "wrong SOP class" and deletes the file

Exchange Folder for export (HFA) and import (PeriData)

The HFA exports (writes) the DICOM OPV files to a specified folder. The HFA software requires that the folder must be mapped for this purpose. To ensure that the mapping always works, it is best to create the Exchange folder on the HFA3 itself. It is shared on the network and then mapped as a network drive. The PeriData app on the receiving PC in the perimeter room accesses the folder via the UNC path, reads the files, and deletes them.

NOTE: The Exchange folder may be as well on the server or the receiving PC. If the target PC is not yet running when the HFA device is started, the mapping will fail. The mapping on the HFA must be changed when replacing PCs.

Mapping on Windows level is strongly recommended. After that, the mapped drive letter is entered into the field "Report Export Location" in the HFA device program . At this field, it is also possible to enter an UNC path or connect a network drive. However, this frequently caused problems.

1 case A. Actions at WINDOWS level (Exchange folder on the HFA PC - both in the same network)

on the HFA:

• Windows-KEY >> taskbar and desktop appear >> open File Explorer
  if the Windows key does not react, then the device is in the Zeiss Kiosk Mode. Leave the mode:
  >> Keyboard: ALT-CTRL-DEL (Task Manager appears)
  >> (in the Task Manager) Menu File >> RunNewTask >> open "explorer" (type in) >> explorer opens, taskbar appears
• (in File Explorer) create the directory C:\PeridataExchangeOnHfa
• (properties of the directory) Share directory for Everyone and Full Control (harmless, because it is only used for temporary files)
• (if not already done) Share HFA-PC in the network
• (in File Explorer) Network > "840-..." (this HFA PC) > folder "PeridataExchangeOnHfa"  >>  context menu  >>  Map Network Drive  >>  select drive letter ("P" for Peridata)  >>  Reconnect at sign-in = YES
• IMPORTANT: In a DOMAIN network, the mapping must be carried out as user = DOMAIN ADMINISTRATOR, otherwise it will not be permanent
• Note the UNC path \\840-...\PeridataExchangeOnHfa

on the receiving PC in the perimeter room

• (in File Explorer) network > 840-.. (HFA PC) > PeridataExchangeOnHfa should be visible >> click on the folder >> log in as user "ZEISS", password "November171846", Reconnect at sign-in = YES
• if the HFA PC is not visible: type the UNC path into the address bar - you should now be able to log in with the Zeiss password
• The UNC path of this folder is the special import directory for the PeriData configuration to be typed in

1 case B. Actions at WINDOWS level (Exchange folder on the SERVER - separate networks)

on the server:

• create the directory ‘..\PeridataExchangeHFA<serial number>’ (e.g. ‘PeridataExchangeHFA840-12345’)
• (properties of the directory) share the directory with permissions for Everyone and Full Control (this is safe, as the folder is only used for temporary files)

on the HFA:

• Windows-KEY >> taskbar and desktop appear >> open File Explorer - if the Windows key does not react, then the device is in the Zeiss Kiosk Mode.
• (in File Explorer) open Network > Server > "PeridataExchangeHFA..."  >>  context menu  >>  Map Network Drive  >>  select drive letter ("P" for Peridata)  >>  Reconnect at sign-in = YES
• IMPORTANT: In a DOMAIN network, the mapping must be carried out as user = DOMAIN ADMINISTRATOR, otherwise it will not be permanent

on the receiving PC in the perimeter room:

• (in File Explorer) open network > PeridataExchangeHFA... (HFA PC) > PeridataExchangeOnHfa >> copy the UNC path of this folder
• (in PeriData) Menu Extra > Options > tab "Perimeter" >> special import directory >> enter the UNC path - field length is limited: if the path has more than 39 characters, it has to be mapped

Important: The directory for DATA BACKUP the HFA device (settings and original exam data) is created separately on the server (suggestion: ‘HFA840backup’) and mapped to the HFA with a different drive letter (suggestion: "H" for HFA).

2. Check the network settings in the perimeter control program (change nothing)

• Log in as "Administrator"
• Settings  (symbol wrench)
• Networking
• Adapter settings: shows the current status  (as set in the system)
• Network Drive Configuration: shows the existing mapped drives  (the target drive letter should be in the list)
• Map...  (do not use)
• Dicom Network = disabled

3. Configurate the export settings in the perimeter control program

• Log in as "Administrator"
• Settings  (symbol wrench)
• Specific Settings
• button "Report Output" >> (Header "End of Test Settings")
• Forum Test Database = OFF
• Export EPDF = OFF
• Report Output Default = Export  (the action when you press "SAVE AND EXIT" at the end of an examination - PeriData calls that the "automatic data transmission")
• Report Export File Type = DICOM OPV  (multiple selections possible, only DICOM-OPV shall be activated) - if DICOM OPV is NOT in the list, the license may be missing >> check in the license menu (LIZ HFA3 OPV IOD EXPORT) and contact Zeiss
• Report Export Location = <Drive letter of mapped target folder>  (choose the mapped drive - subdirectories are possible -- ATTENTION: input of UNC paths is possible, but do not work)
• Named Patient Folder = OFF
• Patient ID in Folder Name = OFF
