Connection Diagram
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 be output the audio source signal to the fiber optic converter,
otherwise the equipment will be burned
Troubleshooting of the 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 installing the device, consideration
should be given to the impact of grounding by lightning and
prevention measures. Strong static electricity will damage the
optical device and data chip in the equipment. It is recommended
that when plugging/unplugging 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 the optical
components of the optical converter are very fragile, and you
should avoid causing damage 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 the eyes, so do not have
direct eye contact with the optical components ofthe 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.
