TROUBLESHOOTING
a. 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.
b. 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.
c. 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.
d. 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.
e. Other interference may require the use of a SecurityTronix ground loop isolation filter.
f. Power is on but the controller does not work
– (i) Check to make sure the DIP switches 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: Yellow = A (+), Orange = B (-). (iii)
Check the integrity and continuity of the Unshielded Twisted Pair (UTP) cable.
