Appendix D. Firmware Updates
The CrystalView firmware may be updated by changing the ROM chip in either
the Local or Remote Unit. Contact Rose Electronics for firmware updates.
Appendix E. Video Compensation
When the Video compensation on the Remote Unit cannot be satisfactorily
adjusted using the Sharp, Bright, JP3, JP4, and JP5 jumper settings and either
red, green or blue is over compensated at all settings, the following information
may correct the problem.
Refer to
Figure 4 for jumper locations. Orient the PCB as shown when making
jumper settings.
Jumper JP3 on the remote Units PCB adjusts the gain for Blue.
Jumper JP4 adjusts the gain for Green.
Jumper JP5 adjusts the gain for Red.
With no jumpers installed, there is no additional gain added to the color levels.
The level is what’s provided from the Video card and the Remote Unit. Installing
a jumper on JP3, JP4 or JP5 between the right and center pins increases that
colors gain to its medium setting. Installing a jumper between the center and left
pins increases that colors gain to its maximum setting. Adjustments to both the
Sharp and Bright controls may also have to be done to achieve acceptable Video
quality.
This problem sometimes occurs when using CAT5e or CAT6 cables between the
Local unit and the Remote unit. Changing to standard CAT5 cable sometimes
cures this problem. Also routing the CAT5 cable through patch panels, close to
equipment or machinery, air compressors, high voltage power lines, or other
locations, may create electrical noise and interfere with the color compensation.
