Fiber-Optic Cable
1. For Cable connection, do not bend the cable
narrower than 30 mm (minimum allowable
refraction range).
2. Do not pull the cable from both ends.
3. Do not spin the optical cable while the cable is
connected to connector.
4. Do not knot the optical cable.
Coax Cable
The impedance of the coaxial cable and BNC connectors must be 75 Ohm.
HD-SDI / EX-SDI maximum transmission distance depends on the cable
manufacturer or installation environment.
Note) When selecting a cable, consider the maximum transmission
distance of the cable which depends on its attenuation at 750 MHz.
(dB/100m < 25dB of attenuation is recommended.)
Note) Foamed or high-foamed insulation cable is recommended.
Note) Double or triple shielded cable is recommended.
Can not turn on the
equipment, and LED
indicators do not work.
√Check the power is properly connected
to the equipment.
√Check the input power voltage..
√If it still does not work, please check
the power adapter or replace it.
Nothing shows on the
screen.
√Check video of camera connected to
transmitter. If there is no video output
from camera, nothing could be shown
on the screen.
√Check the power and cable connections
of camera.
√Check the cable connections between
camera, transmitter, receiver and DVR.
Can not control camera’s
OSD menu and PTZ
√Check the RS485 connection among
camera, transmitter, receiver and DVR.
√Check the polarity of RS485(+,-).
√Check the setting of DVR and camera.
If the setting values such as baudrate,
protocol, address are not properly
configured, camera control can not be
achieved.
1. Connect camera’s video output to transmitter’s “HD-SDI In” using coaxial cable.
- Non PoC Camera: Connect power supply and RS485 to control PTZ and OSD of camera.
- PoC Camera: No need for power and RS485 connection.
2. Connect transmitter and receiver using single mode LC type fiber-optic cable.
- When connecting optical cable to the converter, insert fully until you hear a click sound.
- As shown in Figure 1, pull the lever to lock the optical cable not to fall off from the converter.
3. Connect receiver’s “HD-SDI Out” to DVR’s “HD-SDI In” using coaxial cable.
- Non PoC DVR: Connect RS485 to control PTZ and OSD of camera.
- PoC DVR: No need for RS485 connection.
- For each channel, set the DIP switch in front of receiver to select CoC or RS485.
4. Check the status of LED indicators to confirm the correct connections.
- Power: Red LED will be lit if the power is on.
- HD-SDI: Green LED will be lit if the video signal is entered through fiber-optic cable.
- Optic: Green LED will be lit if transmitter and receiver are connected each other.
- CoC(RX): Green LED will be lit if the camera control signal is entered.
5. Check the monitor connected at DVR whether all connected channels are properly displayed.
