  extend hd - cctv links up to 1.0km with power over cable and camera control link over single coax cable eqcologics eqco - sdi30 - 7501 is an extender soluton for hd - sdi links, operatng with 75? coax cable. each unit receives a hd - cctv signal that may be atenuated by up to 220m of coax cable. the repeater contains three critcal components to correct and then retransmit the signal: ? adaptive equalizer to return the signal to its original amplitude and modulation ? reclocker to resynchronize the signal bringing it back to its original condition ? cable driver to retransmit the signal with its original characteristics restored furthermore, the repeater design allows for two unique benefts: ? power can be transmitted from the recorder (dvr) side to the camera over the coax cable. ? up to 6 repeaters may be powered from the coax cable; if only one or two repeaters are used, the power may also be adequate to power the sdi camera. ? a control signal (rs485) can be transmitted from the recorder (dvr) side to the camera over the coax cable repeater enables simultaneous signal transmission, camera control and power over a single cable. implementation each repeater supports a date - rate of 2.97 gbit/s (3g - sdi). a link of up to 220m can be achieved with a data - rate of 1.485 gbit/s (depending on cable quality*). longer lengths can be supported with lower speed cameras: for example, 720m for sdi cameras. up to 5 repeater units can be daisy - chained together, all powered over the coax cable by power injected to the frst repeater. camera control signals and the system power can be injected at the frst repeater (nearest the recorder). control signals and camera power (if appropriate) can similarly be taken from the repeater nearest to the camera and fed into the camera itself. the camera control is via rs485, the most commonly used protocol and a control signal bandwidth of up to 38.4 kbps is supported. open your eyes? *subject to maximum cable atenuaton, see over for details www.eqcologic.com sl - eqc0 - hd - cctv repeater - 0v1 ?2011 eqcologic hd - sdi repeaters for long - haul digital hd - cctv dvr side repeater including link power and control channel in - line hdsdi repeater camera side hdsdi repeater with power and control
