Cabling and connections

Attaching cables to pass-through connectors

The RGB 402 and RGB 404 provide pass-through connectors for composite video, S-video, RJ-45 network and, for the RGB 402 only, two-channel stereo audio. These connectors are mounted on the faceplate. The RJ-45 cable can be plugged in from the back. Coaxial cables and/or twisted pair wires must be soldered to the back side of the S-video and RCA connectors, as described in this section.

Optional adapter plates with various types and combinations of pass-through audio and video connectors are available for the RGB 408. Many adapter plates also require cables and wires to be soldered to the rear connectors.

Attaching coaxial and twisted-pair cables to RCA connectors

For audio, solder the signal wire of a shielded twisted-pair cable to the central solder cup of the RCA connector. Solder the ground wire to the grounded tab, as shown above at right.

Connecting shields

Multiconductor cables such as Extron’s Install Plenum bulk cable contain several braided and foil shields. At the interface end of the cable, the outer braided and foil shields should be connected to the grounded metal wall box (or to a grounding wire if a metal wall box is not used). The wires that make up the braided shield can be unbraided, then twisted together to form a large, multi- strand wire that can be folded back under the wall box cable clamp or attached to the metal wall box with a screw. See the illustration below.

To prevent short circuits, the outer foil shield can be cut back to the point where the cable exits the cable clamp. Both the braided and foil shields should be connected to an equipment ground at the other end of the cable.
