Installation and Operation
The KD-BBTX; KD-BBRX must receive power from the supplied power adapter. We
recommend the use of STP CAT6/STP cabling for best performance.
Before permanently securing the unit or final installation of cabling
behind walls or ceilings, test for proper operation of the unit and the
cables in your system.
1. Find a safe and convenient location for the KD-BBTX; KD-BBRX unit
»
a. The KD-BBTX; KDBBRX is shipped with a convenient mounting clip as an
installation option. Once you have verified operation of the unit with your cables,
secure the mounting clip to a convenient location. Carefully insert the KD-BBTX;
KD-BBRX into the mounting clip provided.
2. Connections
»
a. Plug in desired Video source into HDMI style
connector port of the KD-BBTX; KD-BBRX.
»
b. Plug in desired Audio source*:
»
i. Audio over HDMI or
»
ii. PCM into RCA style connector or
»
iii. Analog L/R Audio into Terminal Block 6c style connector
3. Connecting Unbalanced Analog L/R Audio*
»
a. On Terminal Block 6c Style Connector, depress orange buttons with small
screwdriver and insert as follows:
»
i. L Signal = Pin 3
»
ii. L Ground = Pin 2
»
iii. R Signal = Pin 6
»
iv. R Ground = Pin 5
4. Connecting Balanced Analog L/R Audio*
»
a. On Terminal Block 6c Style Connector, depress orange buttons with small
screwdriver and insert as follows:
»
i. L+ = Pin 1
»
ii. L Ground = Pin 2
»
iii. L- = Pin 3
»
iv. R+ = Pin 4
»
v. R Ground = Pin 5
»
vi. R- = Pin 6
5. Connecting RS-232 & IR
»
a. On Terminal Block 5c Style Connector, depress orange buttons with small
screwdriver and insert as follows:
»
i. RS-232 Transmit (Tx) = Pin 1
»
ii. RS-232 Receive (Rx) = Pin 2
»
iii. RS-232 Ground = Pin 3
»
iv. IR Bi-Directional Signal = Pin 4
»
v. IR Ground = Pin 5
»
Note: The use of an IR emitter / receiver that utilizes only two wires (data
and ground) is recommended.
6. Select dip switch positions on the front of the unit according to the choices below:
»
a. DDC
»
b. Audio
»
i. PCM
»
ii. L/R
7. Connect the supplied power adapter and plug it into the power input jack. You
should see the “Power” LED illuminate
* HDMI HDCP handshake information (DDC) and external audio cannot be supported simultaneously.

Troubleshooting
Most issues with the KD-BBTX; KD-BBRX setup will involve resolution and distance
performance. If you experience problems (no image, video artifacts, picture dropout,
noise) here are a few things to try:
1. Allow auto-equalization to take place after initial setup. Auto-equalization may take
up to five minutes.
2. HDMI HDCP handshake information (DDC) and external audio cannot be supported
simultaneously. KD-BBTX; KD-BBRX supports either HDMI with HDCP or HDMI/
DVI without HDCP in addition to external audio (L/R or PCM). IR and RS-232
control signals are supported in either scenario.
3. Use the shortest possible HDMI/DVI and CAT6/STP cables between devices.
4. Lower the output resolution of the image source.
5. Use Key Digital HDMI cables.
6. Verify that the “Link” light is active on KD-BBTX; KD-BBRX. “Link” light will not
illuminate or possibly flicker if the CAT6/STP cabling is not transmitting/receiving all
necessary data.
7. Re-terminate CAT6/STP cabling in accordance with TIA/EIA-568-A or TIA/EIA-568-B
pin-pair assignments (see diagram below).
