on all input signals. This creates a light-based bridge that eliminates direct electrical contact, a critical feature for maintaining signal integrity in electronically "noisy" industrial environments. Control Capabilities
The versatility of the D302 becomes apparent in three primary industries: Bl-mach-v1.1 D302
: Connect a USB cable from your computer to the board to provide 5V to the logic side. The PW(5V) LED should light up. on all input signals
: Connect the board to your computer's parallel port using a DB25 male-to-female cable . Bl-mach-v1.1 D302
: Uses optical coupling (opto-isolation) for all input signals and the 0–10V analog spindle output to prevent electrical interference from damaging the PC.
: Detailed visual instructions for connecting the board to motor drivers are provided in the BL-MACH-V1.1 Instruction PDF .
