ASCII Programming Syntax
HOW TO TYPE
In these programming instructions the exact ASCII syntax to be entered on the keyboard will
be given in the font used in this example: DPS=HELLO
8
. Specifically, the field:
DPS, the equal
sign and the word HELLO would be typed, followed immediately by pressing the Enter key. We
will use
8
as the symbol for Enter.
Take time to type deliberately and slowly. Even at 9600 bps, some delays are inherent in the
communications between the computer and the encoder. One characteristic of typing too quickly
will be the omission of line feeds in responses returned from the encoder.
CORRECTING MISTAKES
Under HyperTerminal, use the Enter key to drop to a new line, if required, and use either the
Backspace key or the keyboard’s directional arrows to navigate within a text entry. Overtyping an
entry will automatically replace the previous characters. What is shown on the screen before the
Enter key is pressed is what will be sent to the encoder.
VALIDITY SYMBOLS
The SmartGen 6.0 ignores ASCII inputs that do not conform to proper formatting rules. This
is an important feature when the encoder is connected full-time to station automation. When a
valid command is accepted by the encoder, it returns OK to the computer screen. If a data input
is properly formatted, but is ambiguous or otherwise not accurate, the screen will display NO.
Examples of valid and invalid commands are shown below. Follow programming instructions
exactly to ensure that commands will be accepted.
