Connecting to scanner
According to DMX512 protocol, DMX signal cable must be screened twist cable with impedance of 120Ω. 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 signal + and foot 2
is signal -. Foot 2 and foot 3 of the plug cannot be confused.
To ensure correct DMX signal transmission, an 120Ω terminal matching resistance must be connected to the
last equipment to absorb terminal signal reflection. The operation is as following: connect a 120Ω 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
GOBO 200 scanner controller utilizes channel 1-96 of DMX512 to transmit the control signals to various
scanners. Each scanner is fixed with 8 control channels.
