POWER indicator on the back of the optical transceiver should now be visible which indicates that the transmit lasers are now on Although the TereScope laser transmitters meet ANSI standards for eye safety at the transmit aperture fault conditions could occur that will increase the laser output above eye safety limits Never look in the direction of the other transceiver through binoculars which could magnify the apparent intensity and avoid looking directly into the transmit apertures of any TereScope 3000 The spotting scope mounted beneath the weather shield has been treated with a special IR filter which makes it eye safe during an installation The TereScope 3000 was designed for easy and quick alignment The two diagnostic tools that greatly simplify the alignment are a TV or other video monitor and a PalmPilot or laptop PC 1 Setup a TV BW NTSC standard or other video monitor that is shaded from the sun Open up the electronics box Attach a RG 59 video coaxial cable to the BNC video connector located inside the electronics box see Figure 3 and plug the other end of the cable into the video input of the TV a BNC to RCA adapter may be required The TV will be used for visual alignment monitoring the laser light as it approaches the detector 2 Plug in either a PalmPilot running the TereScope Control software or a laptop PC running the TereScope Monitor software to the RS 232 serial port located connector located inside the elect

TereScope An additional 3 strands of multimode fiber for a total of 5 strands two for the serial line and one for video need to be run from the control room to the TereScopes for remote management Running additional strands of multimode fiber is recommended for redundancy Fiber transceivers both in the electronics box of the TereScope and the control room will be required Contact MRV Communications for more details about the fiber transceivers We recommend using fiber optic cable instead of copper for rooftop installations to avoid the risk of exposing computer equipment in your control room to the threat of lightning strikes A weather rated power source must be available This line should be isolated from other heavy equipment such as air conditioners and should provide either 100 120 or 200 240 VAC depending on the configuration between 50 and 60 Hz with at least a 15 Amp capability unless other arrangements have been made with MRV Communications in advance STANDARD MOUNTING INSTRUCTIONS Due to the narrowness of the laser beam used by the systems precise alignment is critical to optimal performance of the TereScope and a rigid mounting surface must be found The bolt circle on the base plate of the TereScope is 6 inches in diameter The units can therefore be mounted directly to a concrete ledge on the rooftop if it is at least 8 inches wide A variety of mounting options are displayed in Appendix B of this manual More inform
