Page 5: Uses
USES • Threading on a Lath. • Configure a tachometer on your software. When it is used as a tachometer, you must provide a disk with perforations on the side to provide the reading for the phototransistor. • Use per-rev speed feeds, instead of per-min •... -
Page 6: Wiring
Wiring Please note the wiring diagram bellow. In many cases the photo-transistor provided would not be suitable for your application. In most cases it could be replaced for other photo transistors. For example, you can use a reflective photo-transistor, and placing a piece of tape on the spindle. RJ45 Connector The RJ45 connector is for connecting the boards directly using a RJ45 connector with standard network cable. -
Page 7: Tuning
Test the card by connecting the photo-transistor, the power supply, and a LED in the output pins. The LED indicates the output signal status. Note: Open collector output requires an external pull-up resistor to generate a High. BLOCK DIAGRAM Fig. 2 C3 Block Diagram User’s Manual Page 5... -
Page 8: Configuration Jumpers
CONFIGURATION JUMPERS This board includes two configuration jumpers in order to select the C3 output features. Active low or active high output 1-2: Active Low Output 2-3: Active High Output Open Collector (OC) or TTL output 1-2: Open Collector Output 2-3: TTL Output Note: Open collector output allows generate higher voltage output signal. -
Page 9: Troubleshooting
TROUBLESHOOTING SYMPTOM: THE PC DOES NOT REACT TO THE SIGNAL. POSSIBLE CAUSE POSSIBLE SOLUTIONS Pin conflict or mach3 configuration. Go to the device manager in windows It is possible that the port address and check the memory address used for used for the pin is not right, or that the parallel port you are using. -
