CN0170 HARDWARE MANUAL
All inputs, outputs and power supply connections pass through four "D"
type connectors located on the top edge of the CN0170. These connectors
are arranged according to function, consisting of two motor drive
connectors, a serial interface connector and a machine control/power
supply connector. Centent Company can provide an optional serial
interface cable to connect the CN0170 to an IBM compatible personal
computer. The customer must supply the mating socket connectors and
cables for motor and control connections, and serial connections if more
than one CN0170 is "daisy-chained" together. The connector locations are
shown in Figure 1.

X-AXIS, Y-AXIS CONNECTOR:
The motor drive connectors are D9 plug connectors labeled "X-AXIS" and
"Y-AXIS". They form the interface between the CN0170 and the motor
drives. The output signals from the axis connectors are STEP, DIR and
ISET. IRET is the ground reference and is required only if ISET is used.
STEP: (pin 4)
The STEP output connects to the step motor drive's STEP or PULSE input.
The output is 5 volts for a logical '1' and zero volts for a logical '0'. The
output can sink a maximum current of 50 milliamps at a logical '0' state.
The output is TTL and 5V CMOS compatible. In most instances it is also
directly compatible with opto-isolated step motor drive inputs. The STEP
pulse rate is user selectable to x1, x2, x10 and x125 of the CN0170's
programmed full-step rate. This maintains the same programmed motor
shaft speed when using full-step, half-step, 10 microstep and 125
microstep drives respectively. Drives with other resolutions may be used,
however the motor parameters must be reprogrammed accordingly. The
