Appendix H — Symbol Configuration

You can configure your scanner by presenting Code 128 symbols that the MS-3 scan-

ner responds to as serial commands. Note: Your scanner does not need to be enabled

for Code 128 in order to enter symbol configuration.

Entering Symbol Configuration

The symbol used to enter configuration is the 7-character code 128 symbol shown

below. It is not required that the scanner be configured to read code 128 symbols to

read this start symbol or the following configuration symbols.

To setup for symbol configuration:

1. Put the scanner in a read cycle mode.

2. Place a special Code 128 configuration start symbol in the scanners field of view.

Use this symbol or one that you have created yourself.

If the scanner is able to read the start symbol, it will begin to beep and the perfor-

mance LEDs will be activated.

3. When the scanner starts to beep, remove the configuration symbol from the scan-

ner’s field of view.

The beeping will end and the scanner will be in the configuration mode.

During the configuration mode the LEDs will emit a side to side “Knight Rider” pat-

tern to let you know you are currently ready to configure.

You can create your own start symbol by encoding the following in Code 128:

FNC4 <_CFG>.

Using Configuration Symbols

Once in symbol configuration mode, serial command data encoded in Code 128 sym-

bols is read by the scanner as serial input.

Configuration symbols must meet the following conditions:

1. The only valid configuration symbols are Code 128.

2. Symbol data may contain more than one command, but individual symbols must

be presented one at a time. This is because only the first symbol in a read cycle

record will be used as a possible configuration symbol.
