embedded in operation board or directly installed in 19’’ shelf or cabinet.
The power of 192 scanner controller has steady voltage output in so wide range of power supply
voltage that it is adopt to the power supply of all the world .beafore the power supply is
connected ,.Please check whether the voltage is in normal range of 192
When the fuse needs to be replaced,please use the fuse with with the current capacity signed on
the rear of the 192.
Connecting to scanner
According to DMX512 protocol , DMX signal cable must be screened twist cable with
impedance of 120
Ω
. In practical engineering installation, if the whole length of the cable is short,
the cable may be replaced by high quality screened two-core microphone cable.
User joins each end of the cable to a XLR plug. Foot 1of the XLR plug is connected to the screen
net of the cable. Twist lines (distinguished by different colors) are connected to foot 2 and 3. Foot
3 is and foot 2 is signal -. Foot 2 and foot 3 of the plug cannot be confused.
To ensure correct DMX signal transmission, an 120
Ω
terminal matching resistance must be
connected to the last equipment to absorb terminal signal reflection. The operation is as following:
connect a 120
Ω
resistance to foot 2 and foot 3 of a plug then plug it to the output of the last
scanner (or other equipment).

Address distribution of DMX512
192 scanner controller utilizes channel 1-192 of DMX512 to transmit the control signals to
various scanners. Each scanner is fixed with 16 control channels.
