There are many VNC viewers available for both PC
and tablet use. Due to the ever changing market and
availability of such applications, it is not possible to
test them all for compatibility or provide assistance
for their use with the 4848T. It is the responsibil-
ity of the end user to test the chosen VNC client
for compatibility with the 4848T prior to putting
the unit into service. If the VNC client viewer has
compatibility issues with the 4848T, it can cause the
VNC server to stop responding and/or shut down
requiring power to be cycled to the 4848T in order
to reboot the system and restart the server.

tested for compatibility with the 4848T and a free
version can be obtained from RealVNC for PC/MAC
use. RealVNC does offer a version for the iPad that
can be obtained through the App Store for a small
fee.

Once the connection is established, the current
4848T display will be shown on your desktop. The
image will be a duplicate of what is on the 4848T.
As you manipulate the screen, the display of the
4848T will also be manipulated so that any local
operator will be able to see what is happening and
vice versa.

4848T Reactor Controller with Touchscreen
Multiple instances of the VNC viewer can be started
on your PC. By running multiple viewers, you can
have access to multiple 4848T controllers right
from your desktop. The heading of each VNC viewer
window will use the "VNC Device Name" entry for
the header. By entering a unique name for each
4848T, you can identify each VNC connection and
know which system you are accessing.
The VNC viewer is meant to be used for short term
control access to the 4848T. It is not meant for long
term monitoring of system operation. If long term
monitoring access is desired, use the built-in web
server of the 4848T or a PC with FDC software to
monitor and control the 4848T over its serial com-
munications port. The web server interface and PC
software is designed for long term monitoring and
status updates.
Due to the nature of VNC operation, and for secu-
rity reasons, the VNC viewer connection should
not be left open on your desktop. The viewer con-
nection should be opened in order to perform the
necessary control and/or status check of system
operation, and then closed once the task is com-
plete. Accidental manipulation of the control or
erroneous network activity could cause connection
problems over the VNC interface and result
in the VNC server shutting down and requiring the
4848T to be restarted in order to regain access.
NOTE: Some viewers may also contain additional
features for file transfer and other high level func-
tions. These functions are NOT compatible with
the 4848T. Any attempt to use them may cause
the 4848T VNC server to malfunction and require
power to be cycled in order to reboot the system.
