12INTRODUCTION
The DPD72351 is a single-axis programmable indexer/ driver/ power supply
package based on the SMC35 chip.  All the necessary motion parameters can be
programmed, including the maximum speed the motor will turn, the minimum or
base speed, the acceleration rate, the deceleration rate, as well as many other
parameters.  Encoder feedback can be used to verify and auto-correct the motor
position while under computer control. Eight outputs can be turned on and eight
inputs can be read per axis....

COMMUNICATING WITH THE INDEXER
Anaheim Automation programmable indexers communicate by using the RS232C
or RS422 standards.  Most computers contain at least one RS232 serial port.
Some industrial computers have a RS422 serial port.  To communicate with the
DPD72351, use connector...

DTE vs DCE                                   
There are two types of devices defined.  The first is called DTE (Data Terminal
Equipment).  Examples of this would be a terminal, or an IBM Compatible
Computer.  The second type of device is a DCE (Data Communication Equipment).
