Video Picture is black and white not colour
a) You system requires a monitor ID code to boot into the correct video mode. Please
contact technical support on details to correct this.
•
Windows or Windows NT will only boot into a low-resolution graphics mode.
a) The problem could be Monitor ID. See above.
b) If your graphics card supports VESA DDC (Display Data Channel) configure the
graphics driver by explicitly telling it which make and model of monitor you have
rather than using DDC.
•
Is it possible to use a cable length of more than 300m?
The Voyager has been designed to produce acceptable results with Super VGA
resolutions at the maximum cable length. It may be possible to run up to 500m
(Voyager 300 only) at the standard VGA resolution (640x480). However, we cannot
guarantee that this will work in every instance.
•
Can Voyager units be chained to allow operation over more than 300m/1000ft?
No, the chaining is not possible.
•
Which cable is better UTP or STP?
UTP cable will give the best quality video over long distances because it has less
capacitance per unit length. However, STP
may
be a better choice in electrically noisy
environments.
The Voyager 125H is optimized for both UTP and STP.
•
When using UTP what is the best way to ensure the system does not suffer from
any interference?
This product is designed to withstand high levels of interference whilst using UTP over
long distances. To further reduce the potential for interference consider the following:
a) Ensuring that the computer and remote monitor are both connected to the same
mains phase.
b) Ensuring that the AC voltage across the mains grounds (at the local PC & remote
monitor) is less than 2V.
c) Using a clean earth system (if your site has one installed).
d) Routing the interconnection cable away from other cables.
e) Trying STP cable if you think noise could be a problem.
•
Is the Voyager suitable for use between buildings?
The Voyager does not have line isolation. Therefore, operation between buildings is not
recommended.
•
Is the Voyager connectable to my network?
The Voyager uses the same cable as your network, but it cannot be connected into your
network in any way.
The Voyager must have dedicated cables in the network.
