ASCII and Extended ASCII

Characters

This appendix includes all the ASCII and Extended ASCII characters
you can enter in a message.

The first 31 characters are used as ASCII Control Code
characters. They are used to embed control codes in messages
sent to slaves.

Characters numbered 032 to 0127 are usually typed in from the
computer keyboard.

Characters numbered 0128 to 0255 are Extended ASCII
characters. The 850 version of the Extended ASCII character list
is designed for use with European languages.

To enter an ASCII character in a message:

1. Place the insertion bar in the Edit Box where the ASCII character

is to go.

2. Hold down the

ALT

key while entering the number in the keypad.

The corresponding character appears at the insertion point.

To enter an ASCII Control Character in a message to be sent to
a slave device:

1. Place the insertion bar in the Edit Box where the ASCII Control

Code should be embedded.

2. Click the Embedded Variable icon, or open the Format menu.

3. Select ASCII Control Char to open the ASCII Control Character

dialog.

4. Use the scroll bar to locate the number you want.

5. Highlight it and select OK.

A placeholder ~ for the character appears in the Edit Box at the
insertion point. A Control Code character determines how the
message is displayed by the slave device(s).
