EQCO-SDI-30-7502 HD-SDI REPEATER USER’S GUIDE Chapter 1. Product Overview 1.1 INTRODUCTION The repeater contains three critical components to correct and then retransmit the HD-SDI signal: • Adaptive Equalizer to return the signal to its original amplitude and modulation • Reclocker to resynchronize the signal and bring it back to its original condition • Cable Driver to retransmit the signal with its original characteristics restored Furthermore, the repeater design allows for unique benefits: • Power can be transmitted from the recorder side to the camera over the coax cable. • Up to five repeaters may be powered from the coax cable; if one or two repeaters are used, the power may also be adequate to power the camera on the remote end. • Five or more repeaters can be connected if power is added in the middle of the link. • A control signal (RS485) can be transmitted from the recorder (DVR) side to the camera over the coax cable. • Simultaneous video signal transmission, camera control and power over a single cable allows full re-use of legacy coax infrastructure. 1.2 REQUIREMENTS • 75Ω coaxial cable with 75Ω BNC connectors on each end (maximum length based on cable type – see specifications). • HD-SDI camera or source (with or without power over coax capability). • HD-SDI DVR or capture source (with or without power over coax capability). • 24V DC power supply (not provided). • 12V DC power supplies can be used if only two repeaters are used and there is no need to power the camera over the coax (not provided). 2014 Microchip Technology Inc. DS50002303B-page 9 EQCO-SDI-30-7502 HD-SDI Repeater User’s Guide 1.3 SETUP Each repeater supports a link of up to 200m with a data rate of 1.485 Gbps and 130m at 2.97 Gbps (depending on cable quality). Longer lengths can be supported with lower-speed cameras; e.g., 720m for SDI cameras. Up to five repeater units can be daisy-chained together, all powered over the coax cable by power injected to the first repeater. Follow these steps: 1. Connect the 24V DC or 12V DC power supply (for the DVR side) and the RS485 in/out cables to the plug connector. 2. Plug the plug connector into the repeater (on the camera side or DVR side). 3. When using multiple repeaters and the RS485 uplink, connect the RS485 Out cable to the camera (or breakout board) at the camera side. 4. When using multiple repeaters and the RS485 uplink, connect the RS485 In cable to the DVR (or breakout board) at the DVR side. 5. Connect the 75Ω coaxial cable to the 75Ω BNC connector on the repeater. 6. If powering a camera or remote source over the coax, draw power from the VCC and GND pins of the plug connector at the camera side. Note 1: 2: DS50002303B-page 10 If used, repeaters 2-5 are powered via the first repeater. Camera control is one-way only, from the DVR to the camera. 2014 Microchip Technology Inc. Product Overview 1.4 CONNECTION DIAGRAM Extend HD-SDI links up to 1 km with power over cable and camera control link over a single coax cable. FIGURE 1-1: CAMERA SIDE HD-SDI REPEATER WITH POWER AND CONTROL OUTPUTS FIGURE 1-2: IN-LINE HD-SDI REPEATER (UP TO FIVE REPEATERS BEFORE ADDITIONAL POWER IS REQUIRED) FIGURE 1-3: DVR SIDE REPEATER INCLUDING LINK POWER AND CONTROL CHANNEL The characteristic impedances of the coaxial cables and connectors must all match. The EQCO-SDI-30-7502 Repeater must have 75Ω (± 3Ω) impedance. Figure 1-4 shows the difference between a 50Ω connector versus a 75Ω connector. A 75Ω coaxial cable with 75Ω connectors must be used. FIGURE 1-4: 2014 Microchip Technology Inc. DIFFERENCE BETWEEN 50Ω VS. 75Ω CONNECTORS DS50002303B-page 11 EQCO-SDI-30-7502 HD-SDI Repeater User’s Guide 1.5 CABLE CONNECTION When using the repeater at the DVR side, the 24V DC or 12V DC power supply can be connected to the plug connector. The cable used for the RS485 input signal should be connected to the RS485 pins of the plug connector. Make sure that all the cables are connected in the right order, as shown in Figure 1-5. Insert the plug connector into the repeater box at the DVR side. When using the repeater at the camera side, the camera can be powered (when no more than two repeaters are used) by connecting the power to the VCC and GND of the plug connector. Connect the RS485 output pins to the right pins of the Mini-Combicon plug connector as illustrated in Figure 1-6. Make sure that all the cables are connected in the right order. Insert the plug connector into the repeater box at the camera side. Note: DS50002303B-page 12 The camera can be powered if only two repeaters are used in-line. It is necessary to power the first repeater with 24V. Using more than two repeaters will not allow sufficient power supply for powering the camera. In this case, external power must be supplied to the camera. FIGURE 1-5: DVR SIDE FIGURE 1-6: CAMERA SIDE 2014 Microchip Technology Inc. EQCO-SDI-30-7502 HD-SDI REPEATER USER’S GUIDE Appendix A.
