Appendix B. Dc Restoration Setting - Black Box AC1063A-R2 Manual

CAT5 MULTI VGA SYSTEM
Appendix B. DC Restoration of AC
The Cat5 Multi VGA system is designed to function with DC coupled signals
with the black level referenced to 0 volts. Nearly all VGA cards function this
way. However, some media servers or digital camera devices provide AC
coupled signals and can cause a green color shift in the video. This is a result
of the sync clamping on the Red and Blue channels. The single port
transmitter has been designed with full DC restore capability. A simple switch
setting is all that is required.
The following diagrams show the switch location and settings for the
AC1060A transmitter assembly.
Note: Switch settings other than shown below may result in unpredictable
performance and are not supported by Black Box.
DC restore option (AC1060A-R2 only):
Mode 1 Enable: Switch position B, C ON (UP)
Mode 2 Enable: Switch position A, C ON (UP)
Disable: Switch position B, C OFF (default)
