Table 6-3: Interconnection between Master and IO Extender
The video interface of the IO Extender board should only be connected to the master in case an external video
source shall be used.
IMPORTANT: In case X1, X3 and X5 of the IO Extender are connected to the TX master, the following resistors
at the TX Master need to be removed:
• Serial resistors: R49, R50, R52, R53, R55, R56, R58, R59, R61, R62, R64, R65, R67, R68, R71, R72,
R75, R76, R78, R79
• In case of external RGB interface, termination resistors: R51, R54, R57, R60, R63, R66, R69, R73, R77,
R80
In addition, the following resistors need to be removed to decouple the direct HDMI RGB pixel path (by default
not mounted): R86, R88 .... R138, R140.
Dip Switch S1 needs be configured to 1100 ([4:1]) for correct operation.
