4. optic cable has an even smaller core only 00032 to 0004 inches 8 10 microns This is smaller than a human hair As a result any minute particles of dirt or dust can easily block the fiber from accepting or radiating light Therefore the key word is cleanliness Always use the dust caps provided with all optical connectors whenever they are exposed to air Also it is a good idea to gently clean the tip of an optical connector with a lint free cloth moist ened with alcohol whenever dust is suspected The status of any of the audio indicator LEDs should provide the first clue as to the origin of any operation failure If all the LEDs are off it usually means that the fiber is broken or has too much attenuation Next be certain that the input and output signal connections are proper Due to the number of positions it is possible that there may be wrong connections Finally although multimode and single mode devices may look the same they will not operate properly together Using the wrong device or fiber can easily add more attenuation than specified resulting in poor overall perfor mance If after reviewing the above possibilities the system is still not operating please contact the Customer Service Department for further assistance MAINTENANCE The Pure Digital Fiberlink 4160 and 4320 Series transmission units have been manufactured using the latest semiconductor devices and techniques that elec tronic technology h
5. 60 4320 Series transmission systems are nor mally preset for immediate use with the audio input circuitry set for balanced 600 Ohm input impedance and the output set for balanced audio Ifa different protocol is desired it can be easily selected using the flip switches located on the back panel of the unit See table on next page There are indicator LEDs on the units for monitoring purposes and several user selectable options for configuring audio inputs and outputs The following instructions describe the typical installation procedure and the function of the LED indicators 1 The various options as already mentioned have been preset If unbal anced high input impedance or unbalanced output is desired please refer to instructions on the following page 2 When using single optical configuration connect a fiber optic cable between the Optical 1 connectors of the Pure Digital Fiberlink trans mitter and receiver units When using redundant configuration also connect a fiber cable between the Optical 2 connectors on each unit 3 Apply power to both Pure Digital Fiberlink units 4 When power is applied the green POWER LED will light indicating the presence of operating power 5 Connect the audio input signals to the proper positions on the removable terminal blocks Refer to the next section for details Be certain to check all connections and assure that inputs and outputs are not inter mixed 6 The green audio LED
