MO	a9	WC	d4	reserved	ff
SH	aa	reserved	d5

The DMC-1700/1800 returns a : for valid commands. The DMC-1700/1800 returns a ? for invalid commands.

For example, if the command BG is sent in lower case, the DMC-1700/1800 will return a ?.

:bg <enter>	invalid command, lower case
?	DMC-1700/1800 returns a ?

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 <enter>	Tell Code command
1 Unrecognized command	Returned response

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 section.

Interrogating the Controller

Interrogation Commands

The DMC-1700/1800 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.
