Controller Response to DATA

The CDS-3310 returns a : for valid commands and a ? for invalid commands.

For example, if the command BG is sent in lower case, the CDS-3310 will return a ?.

:bg <return>

When the controller receives an invalid command the user can request the error code. The error code

will specify the reason for the invalid command response. To request the error code type the

command: TC1 For example:

?TC1 <return>

1 Unrecognized Command

There are many reasons for receiving an invalid command response. The most common reasons are:

unrecognized command (such as typographical entry or lower case), command given at improper time

(such as during motion), or a command out of range (such as exceeding maximum speed). A complete

listing of all codes is listed in the TC command in the Command Reference.

The CDS-3310 has a set of commands that directly interrogate the controller. When the command is

entered, the requested data is returned in decimal format on the next line followed by a carriage return

and line feed. The format of the returned data can be changed using the Position Format (PF), Variable

Format (VF) and Leading Zeros (LZ) command. See Chapter 7 and the Command Reference.
