Problem Possible reason Solution
No movement and ima
ge at power-on
1.Check the connection of
C power input
2.Turn off power and check t
he transformer
1.Check the power
connection, make sure the soc
ket is well connected
2.Make sure the power outlet is
working
Power-on shows
mage,
but the controlle
r doesnot work
1. DIP switch setting is incorrect
2.RS485 interface is not connec
ted or is not connected corre
ctly
3.There is a problem with the
S485 line
1. Refer to setup instructi
ons, re-set the DIP switches.
2.Check RS485 interface,
sure the wires are well connect
ed and in the proper slots
3.Refer to the Appendix: RS485
Blurred Image Ball case is dirty Clean the ball case
2. 2. Setting of DIP Switches
The internal black case has 8 DIP switches. 8,7,6,5,4,3,2,1 are for Addres
s setting, while 10,9 are for Communication Baud Rate.
In the following table, tag “1” for DIP switch “ON”; tag “0” for DIP switch “off”.
a) Setting Baud Rate

4800bps 1 0 9600bps 0 0
b) b) Setting Address Code
In a system, decoder includes intelligent speed dome camera and common de
coder. No repeating address codes exist. As you see in the table, “1” for “O
N”, “0” for “OFF”
