TROUBLESHOOTING
No picture after applying power
– (i) check all plugs and cables are
connected to the proper connectors: (ii) ensure your power supply is
providing the correct voltage and enough current.
The picture has ripples
– (i) Check to see if the power supply is
experiencing AC ripple. If so, a filter may be required. (ii) Determine if
the monitor is faulty. (iii) Determine if other peripheral equipment is
causing the ripple and if so make the necessary adjustments.
The picture background continuously changes color
– A fluorescent
lamp’s magnetic field may cause color roll. If possible, increase the
distance between the camera and any fluorescent lamps in the vicinity.
The picture appears smeared
– (i) The power supply voltage level may
be unstable. Try another power supply. (ii) Ensure the cables are
correctly connected and of the right impedance (75 ohms).
Other interference may require the use of a SecurityTronix ground loop
isolation filter.
Power is on but the controller does not work
– (i) Check to make sure
the DIP switches or software addressing are all set correctly for address,
baud rate and protocol. (ii) Check that the RS485 wires at the camera
and controller have correct polarities. The camera colors are: Blue = A
(+), Green = B (-). (iii) Check the integrity and continuity of the
Unshielded Twisted Pair (UTP) cable.
