2.Determine what colors of each conductor type will be used for which signal, or use the examples provided in this manual.

3.Strip 7” to 8” (18 cm to 20 cm) of the outer jacket from the end of the cable.

4.Use a pointed tool to separate the braided wire shield sur- rounding the cable. Pull the ends of the braid away from the cable, twist the braid wires together, and clamp them to the electrical box (if used). See “Connecting shields”, page 2-10.

5.Unroll and cut off the foil shield.

6.Place a 1.5” to 2” (3.8 cm to 5 cm) piece of heat shrink on each mini coaxial cable, but do not heat it yet.

7.Install and crimp a male BNC connector onto each of five mini coaxial cables. The white mini coaxial cable is not used by the buffer; it can be insulated and set aside or trimmed back 7” to 8”.

8.Slide the heat shrink over the ferrule of each attached

BNC connector, and heat it to fasten the heat shrink in place.

9.Place a 6” (15 cm) piece of heat shrink on each set of shielded twisted pair wires (one on white/black, one on red/black, one on orange/black), but do not apply heat yet.

10.Separate the wire braid from the white/black and red/black shielded twisted pair conductors for about 1” (2.5 cm) from the ends. For each twisted pair set, twist the strands of the wire braid together.

11.Strip 1/4” (13 mm) of insulation from the ends of the white/black and red/black twisted pair wires. Twist each conductor’s stranded wires.

12.The left half of the 10-pole connector is for audio output to the RGB 320. See the diagrams on pages 2-14 and 2-15, which show wiring for balanced audio output. See the illustration below for a comparison of wiring for unbalanced (high impedance) or balanced (high impedance or 600 ohms) stereo audio output.

Connect the sleeve to ground. Connecting the sleeve to a negative (-) terminal will damage the audio output circuits.

Insert the tips of the white/black twisted pair wires into the captive screw connector for left audio. Insert the tips of the red/black twisted pair wires into the captive screw connector for right audio. For balanced audio output, white = L+, black = L-; red = R+, black = R-.

13.Twist together the wire braids from both (white/black and red/black) twisted pairs.

14.Insert the twisted braid into the ground connection on the audio part of the captive screw connector. See the illustra- tions in step 12 and the wiring diagram on page 2-14.

15.Separate about 1” (2.5 cm) of the wire braid from the ends of the orange/black shielded twisted pair conductors, and cut the braid off.

16.Strip 1/4” (13 mm) of insulation from the ends of the orange/black twisted pair wires. Twist each conductor’s stranded wires.

17.Insert the black wire into the slot for pin A and the orange wire into the slot for pin B of the captive screw connector.

18.Slide the heat shrink on the white/black, red/black, and orange/black twisted pairs toward the connector so no wire braid is exposed near the connector. Apply heat to fasten the heat shrink onto the wires to insulate the braided shields.

19.Strip 1/4” (13 mm) of insulation from the ends of the brown, violet, and grey single conductor (20 AWG) wires.

20.Insert the tip of the brown wire into the slot for pin C on the captive screw connector, insert the violet wire into D, and the grey wire into E. See page 2-14.

21.Repeat steps 3 through 20 to attach a 10-pole captive screw connector, BNCs, and heat shrink to the other end of the cable. Make sure that connections are the same on both ends.

22.Plug the captive screw connector on one end of the cable into the buffer’s receptacle, and connect the adjacent BNCs to the output BNCs on the buffer’s rear panel.

23.Attach the BNCs and captive screw connector on the other end of the cable to the appropriate input connectors on the RGB 320’s rear panel.

24.Apply power to the RGB 320.
