Note that other hardware platforms, operating systems, and/or VNC clients may also allow proper remote
control. However, is not feasible for Spirent to track and test all of them. If you would like to use a
different client, etc., you should feel free to test it and implement the solution once you are comfortable
with its reliability.
RealVNC 4.1.3 installation and setup
RealVNC 4.1.3 can be downloaded from:
http://www.filehippo.com/download_realvnc/changelog/4977
Once the EXE file is downloaded, run the file and follow the wizard prompts. Default installation settings
are adequate to establish proper functionality; however, if you have expertise with the software, you may
choose some customizations. For example, you could choose not to install the VNC server component,
as the client component is the only necessary component.
Once installed, RealVNC has a variety of options related to VNC connections, accessible from the setup
screen and from a VNC window. Normally, default settings are adequate, however the following settings
may require attention:
Colour level (Colour & Encoding tab) - If you notice problems with performance or other display
functionality, consider trying a different setting such as Low or Full.
Pass special keys directly to server (Inputs tab) - Normally, this setting should be unchecked for
best results. If checked, you may have trouble with operations such as using a PC PrtScn key to
capture a screenshot, because the keyboard input will be passed to the unit, not the PC.
Rate-limit mouse move events (Inputs tab) - Normally, this setting should be checked for best
results. This setting limits the amount of hover/movement-related events sent to the unit, which are
less critical for proper operation. Without this setting, on fast networks the unit may receive more
input than necessary, causing a processing backlog and thus delays in control.
