Installation and Operation

The KD-BBTX; KD-BBRX must receive power from the supplied power adapter. We recommend the use of STP CAT5/5e/6 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

* HDMI HDCP handshake information (DDC) and external audio cannot be supported simultaneously.

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

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 CAT5/5e/6 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 CAT5/5e/6 cabling is not transmitting/receiving all necessary data.

7. Re-terminate CAT5/5e/6 cabling in accordance with TIA/EIA-568-A or TIA/EIA-568-B pin-pair assignments (see diagram below).
