Direct Talk Mode

Direct mode is used to directly control the motion for real time movements through serial com-

munication. The indexer has 14 commands which are easy to remember for direct movement

of a step motor.

Unit Selection

In order to select a unit the @ command followed by 0 (address of the unit) must be sent.

NOTE: There should be no spaces between the @ and the 0.

How to select the unit:

@0 (Unit is selected)

How to get a response from the unit:

@0$ (Carriage Return)

After the $ command, the pulse generator will return a SMSI20 + the current version number.

Note: In direct talk mode each command is followed by a carriage return.

The unit communicates in half duplex mode, therefore proper setup of hyper terminal is neces-

sary to view characters, if characters are to be echoed back to the screen.

Instructions

All instructions require that no spaces be sent between the command and the parameter followed

by a carriage return. The commands are also case sensitive and are all sent as capitals.
