Command Line

The LD100 is programmed by means of a
“Command Line”, which is an ASCII string of up to
255 characters that contains one or more individual
instructions to the LD100. The Command Line
offers the best compromise between manual opera-
tion via a data terminal and automatic control via a
controller.

Command Line Entry

A Command Line can be entered in either upper or
lower case by means of a data terminal or other
controller. The Echo Mode determines the response
of the LD100 to the incoming data stream. If the
Echo Mode is ON (E1 command), the entered char-
acters are echoed back to the host, and any mes-
sage are sent in its entirety. IF Echo Mode is OFF
(E0 command), no characters are sent to host.

Command Syntax

Commands consist of a header followed by a key-
word followed by additional parameters if needed.
The header is used to identify the product, in the
case the header is: LD100, . Keywords are single
characters followed by integers (if needed). All com-
mands must be separated by a comma ‘,’. White
spaces are ignored and may be used. All com-
mands strings are terminated by a CARRIAGE
RETURN (0x0d). Commands may in entered in any
order as the user see fit.
