APPENDIX B:Sync Termination
Appendix C. DC Restoration of AC
coupled source
The Cat5 Multi Video 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:
Enable: Switch position B, C ON (UP)
Disable: Switch position B, C OFF (default)

Appendix D. Rackmounting Units
The Rackmount Kits include brackets for mounting a single transmitter, single
receiver, or a single dual daisychainable receiver. Figure E-1 shows the 1-Unit
Rackmount Bracket (AC1008), which can be used to mount a single CAT5 Multi
VGA System unit on a wall. Figure E-2 shows the 4-Unit Rackmount Bracket
(AC1009), which holds four units in a 19" x 1U rack.
Not shown are brackets for 8 units. The 8 Unit Rackmount Bracket (AC1010) holds
the mounted units like the 4-Unit Rackmount Bracket (AC1009) but is 2U high
instead of 1U high, stacking 4 slots directly above 4 slots.
