Fat Client Remote Scanning is a process used when there is a remote site which does not have appropriate bandwidth for normal scanning.

This process enables the practice to still scan as normal, but schedule the documents to be delivered to the Scan server at a later time.

This is sometimes known as HDR or RDS, the names of the Windows services responsible for transferring the scans:

  • HDR: Host Document Receive (server-side Windows service)
  • RDS: Remote Document Send (workstation-side Windows service)

Technical Details

HDR Schedule

Windows Services

  • HDR is a Windows Service that resides on the server and retrieves incoming scanned files. It then moves the files to the appropriate warehouse.
  • RDS is a Windows Service that resides on the client workstation. It receives the files from the scanner and sends them at a scheduled time to the HDR Service on the server.

Host Document Receive

Host Document Receive moves files from an HDR image queue on the Scan server into the Image Warehouse. The image queue location and schedule are defined in the settings for the HDR service, which can be accessed by launching HDR with the configuration flag:

C:\HDR_Location\HDR.exe -config

Remote Document Send

Remote Document Send moves files from an image queue at the remote site to the HDR image queue on the Scan server. RDS is schedulable and configurable in exactly the same way as Host Document Receive.

Scan Client Configuration

Every scan station at the remote site must be configured to point to the RDS queue on the primary Scan workstation at the remote site. These settings are located in the Workstation section of User Preferences in the ADM/Scan application.
