»
Slots 1-8 are labeled Rx, and are Input Card Slots.
»
Slots 9-16 are labeled Tx, and are Output Card Slots.
2.
If integrating your source via KD-BBTX CAT5 Transmit Balun(s)
»
Set dipswitch # 2 of the KD-BBTX balun to “DDC” in order to establish a proper HDMI
handshake
»
Configure the appropriate Input Card Slot to activate its CAT5 input using ‘SP I xx V y’ RS-
232 command.
»
Where xx = Card Slot # of desired Input
»
Where y = 1 or 2 (1 = HDMI, 2 = CAT5).
»
Note: The default input configuration is “1” for HDMI.
3.
If integrating your output via KD-BBRX CAT5 Receiver Balun(s)

»
Where H = HDMI, C = CAT5 or D = Default EDID Library (01-08)
»
Where yy = Card Slot of # of desired Output (if H or C) (01-08)
