The expansion card is according to the actual
needs of users; is mainly used to increase host’s
extra functions, so as to achieve the user’s
personal needs.
CR-AD3AA0 analog card is used for CR-PGM Ⅲ
programmable control host’s function expansion;
it allows CR-PGM Ⅲ host to increase control
function of DMX512.
Application Characteristics
◆ CR-link protocol input;
◆ DMX512 protocol output;
◆ The maximum 512 channel output;

◆Adopting balance driver and differential
receiver combinations, anti interference ability is
greatly enhanced, namely anti noise interference
ability is good.
Operation Methods

CR-PGM Ⅲ host send certain roads and certain
grey degrees to DMX512 control card, DMX512
control card receive the instruction to make
corresponding output.
◆Following are the programming function
description of CR-PGM Ⅲ when use DMX512
control card
SEND_DMX512()
void SEND_DMX512(String dev,int channel,int
val)
Function: to control DMX512
Parameters:
Dev – lighting device
Channel - : Equipment channel number
Val - :Value of Analog (Note: according to specific
external equipment. )
Example:
lilt_L = L:7:DMX512; // Define DMX512
equipment whose CRLINK ( CAN ) number is 7.
SEND_DMX512(lilt_L,1,255);// to send analog
value 255 to the first way of lilt_L.
