Reminder

1. It is recommended to use the short optical fiber link for the first time to ensure that all the functions of the equipment are normal, and then do long-distance transmission

2. The signal of the fiber optic converter can be output to the power amplifier, but the audio source of the power amplifier can not output the audio source signal to the fiber optic converter, otherwise the equipment will be burned

Troubleshooting of indicator

1: Power indicator is abnormal (POWER)

Answer: Check whether the power adapter meets the equipment requirements or the power adapter fails

Whether the socket is not tight or loose

2: Fiber indicator is abnormal (FIBER)

Answer: Check whether the optical fiber interface is loose and not plugged in

Check whether the optical fiber is too attenuated

3: Video indicator is abnormal  (VIDEO)

Answer: Check the signal source

Replace the video cable

4: Data indicator is abnormal (DATA)

Answer: Check the COM port, whether the baud rate is consistent

Check whether the serial port cable is connected backward

Attention

Lightning protection, static electricity and grounding:

It is recommended that when install the device, consideration should be given to the impact of grounding by lightning, and take prevention measures. Strong static electricity will damage the optical device and data chip in the equipment. It is recommended that when plug/unplug the data port of the optical converter, please disconnect the power supply of the optical converter first.

Fiber and optical components:

Be careful when plugging the optical fiber as optical components of the optical converter is very fragile, and it should avoid causingdamage to the optical components. It should be noted that the light source produced by the optical components of the optical converter will be harmful to eyes, so do not have direct eye contactwith the optical components of optical converter. If you need to detect the optical power of the optical converter, please use the optical power meter.

Equipment and installation procedures:

1.Optical fiber installation: please carefully insert the optical fiber into the optical fiber interface of the optical terminal after confirming that the optical fiber link meets the installation requirements.

2.Equipment installation: The equipment can be distinguished between transmitter and receiver, and it is stated clearly on the label and printed on the chassis of the equipment.
