The status of the VIDEO and AUDIO indicator LEDs should provide the first clue as to the origin of an operational failure. If these 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 correct. Finally, although multimode and single mode devices may look the same, they will not operate properly together.

provides an output to drive a model 6020 Alarm Sensing Module which provides an audible tone and activates a set of contacts for external signaling purposes. The status of the LEDs are as follows: TRANSMITTER and RECEIVER: Power: ON: (GREEN) Indicates that correct power has been applied. TRANSMITTER: Video: OFF: Indicates no video detected on the input. BLINKING GREEN: Indicates either H or V sync detected at the input but not both. STEADY GREEN: Indicates both H and V sync detected on the input.
5. Apply power to both Pure Digital Fiberlink® units. For box versions using DC power connections, refer to Figure 1. 6. When power is applied, the green POWER LED will light, indicating the presence of operating power. The VIDEO LED will give an indication as described on Page 8. 7. The green AUDIO LED will give an indication as stated on Page 8.
