Installation
Installation of the CrystalView consists of four easy steps.
1. Setting the cable length jumpers (if needed).
2. Connecting the cables to the equipment.
3. Applying Power.
4. Adjust the Video compensation (if needed).
For systems that only require running Video through the CrystalView,
(for viewing purposes only) and no Keyboard or Mouse is needed, supplemental
power must be supplied to the Local Unit since the Local Unit gets its power from
the Keyboard port on the CPU. Rose Electronics can supply a power
transformer that connects to the Local Units Keyboard port to provide this power.
This transformer can be ordered from Rose Electronics.
See Appendix C. Parts and Cables for part numbers and descriptions.
Step 1: Setting the Cable Length Jumpers
There are three jumpers labeled JP3, JP4 and JP5, located on the Remote Units
PCB. These three jumpers set the correct level of Video equalization for different
cable lengths. Jumpers JP3, JP4 and JP5 are all factory set to a default of
0 – 300 feet. For cable lengths less than 300 feet, no jumper setting changes
should be needed.
For cable lengths over 300 feet these jumpers need to be set. To set these
jumpers, first carefully remove the Remote Units case by unscrewing the two
side screws and the top screw and lift off the top case exposing the CrystalViews
PCB. Orient the PCB as illustrated in Figure 4 with the cable connections away
from you and the front panel towards you. Set JP3, JP4 and JP5 depending on
the cable length between the Remote Unit and the Local Unit as shown
Figure 4 .
If you are unsure about opening the case and setting the jumpers, please consult
technical support at Rose Electronics.
