CHAPTER 3: Installation 3. Installation 3.1 Installing a Single Hub To install a Video CCTV-A/V Hub that isn’t daisychained or cascaded with any other devices, follow the steps below. CAUTION! Do not attempt to open the housing. There are no user-serviceable parts inside the Video CCTV-A/V Hub. - Page 11 Balun end Hub end Figure 3-1. Measuring cable impedance. The Video CCTV-A/V Hub must be kept away from sources of radio- frequency or electromagnetic radiation; at least: a) 5" (12.7 cm) from power lines carrying 2 kVA or less. b) 12" (30.5 cm) from fluorescent lighting and power lines carrying between 2 and 5 kVA.
- Page 12 CHAPTER 3: Installation 4. Identify the pinout of all involved video baluns and the Video CCTV-A/V Hub to see whether you’ll need to use any cross-pinned cable. For example, if you’re using all Video Stereo Audio Baluns (IC441A-R2), all of the UTP cable can be straight-through-pinned.
- Page 13 VIDEO CCTV-A/V HUB 5. Run the hub’s power cord from the 5-pin DIN power inlet on its rear panel, shown in Figure 3-3, to the nearest working AC power outlet. The Power LED on its front panel, shown in Figure 3-4, should light up and stay on.

CHAPTER 3: Installation 3.3 Installing a Hub in a Daisychain or Cascade One Video CCTV-A/V Hub may be daisychained or cascaded with others in order to distribute a baseband A/V source to more than eight destinations. For example, an A/V presentation from a VCR or DVD player can be distributed to multiple classrooms using preinstalled CAT5 twisted-pair cable, as shown in Figures 3-9 and 3-10. - Page 17 VIDEO CCTV-A/V HUB If you need to reach more destinations than eight hubs can accommodate, you can cascade from each hub to multiple others as shown in Figure 3-10 instead of daisychaining. The regular outputs and looping output can all be used for this purpose—any of these ports may be connected to the input port of another hub.
