A mosaic of retinal images can show visual artifacts (e.g. duplicated retinal vessels or 
non-contiguous retinal vessels) in the areas where two images are stitched together. 
These artifacts can be easily recognized by looking at the original images. 

11.6

 

Remote Viewer 

All of the patient database and the images stored into the 

drs

plus

 memory can be remotely reviewed 

by means of any standard PC connected in the same Local Area Network the 

drs

plus

 is connected to. 

In particular, the Remote Viewer presents to the operator the same screens and commands available 
in the local interface. There are however several differences between the local user interface and the 
Remote Viewer: The configuration and execution of a new exam is not permitted. 

To enable the Remote Viewer, the 

drs

plus

 must be connected to the Local Area Network by means of 

a Ethernet or Wireless connection (Fig. 7). After the connection of the ethernet cable to the Ethernet 
port  located  on  the  back  panel  of  the  device,  the  network  connection  might  require  additional 
configuration (§13.3). Once the connection is up and running, open a browser in the remote PC and 
insert the address of the device: 

http://

nnnnn

.

domain

 

into the address bar. Here: 

- 

nnnnn

 are the 7 characters which compose the serial number of the 

drs

plus

, as reported in 

the device label; 

- 

domain 

is the network domain, if present (optional). 

 

❖

 

The Remote Viewer functionality is available only under license. 

 

❖

 

The Remote Viewer requires a standard Web Browser and does not require 
any additional third-party software to be installed in the remote computer.  

❖

 

The Remote Viewer supports the following browsers: Microsoft Edge, Mozilla 
Firefox  (version  60  or higher), Apple Safari (version 6.2.8 or higher), Google 
Chrome (version 70 or higher). 

❖

 

The Remote Viewer requires the user to log in using the same user credentials 
(username and password) used to log in into the local user interface. 

❖

 

Every  Remote  Viewer  session  is  automatically  closed  after  20  minutes  of 
inactivity. To continue using the Remote Viewer, a new log in is required.
