ADVANCED MICRO SYSTEMS, INC. HARDWARE Product Overview The DCB-274 combines efficient bi-polar chopper Driver circuitry with AMS’ new, powerful SMC-27X2 Micro-controller on a single, heat sink mounted board, to operate small to mid-size stepping motors. It is designed for low cost O.E.M. applications; yet includes many enhanced operating features found in products costing much more: Features • Programmable hold and run currents • Selectable “PLC” sourcing input mode • All inputs

ADVANCED MICRO SYSTEMS, INC. HARDWARE “Do’s, Don’ts and Important Notes” • NEVER connect or disconnect motor wires while power is supplied. • When using a 6 lead motor be sure to insulate/isolate unused wires. • The physical direction of the motor with respect to the direction input will depend on the connection of the motor windings. To reverse the direction of the motor with respect to the direction input, switch the wires on phase 1 or phase 2 of the outputs. **************** WARNIN

ADVANCED MICRO SYSTEMS, INC. HARDWARE Pin 7 - VIO Reference Input This signal defines the input and output voltage range. A “default” voltage of 4.6 volts is derived from the internal +5-volt supply, via a diode. Any external load must be limited to several mA. You may apply an external, higher “VIO” voltage, if appropriate to the application. The input signal thresholds will be approximately ½ of VIO or 2.3 volts. The threshold is the same, independent of PLC or “normal” mode. Input

ADVANCED MICRO SYSTEMS, INC. HARDWARE As an output (as shipped) the signal can be redefined as a stepping pulse output with the “l 2” (lower case L) command. This also defines P5 as a direction output signal. Port 5 Port 5 is an output port/driver, rated at 2-amps. The output signal can be redefined as a direction output with the “l 2” (lower case L) command. Port 4 becomes a step pulse output. The output signal can be redefined as a moving output with the “l 4” (lower case L) command
