Programming Modes (continued)4. During programming, the motor and laser remain active. YOU
CANNOT SCAN ANY BAR CODES WHILE IN PROGRAM MODE.
5. There is a 20 second window between commands. If a 20 second
timeout occurs, the scanner will send a [nak] and you must start
over.
6. To enter serial program mode, send the following command
[stx]999999[etx].
7. To exit serial program mode, send the following command
[stx]999999[etx], the scanner will respond with an [ack] and a long
beep.
8. This mode uses the current Baud Rate, Parity, Stop Bits and Data
Bits settings that are configured in the scanner. The default settings
of the scanner are 9600, Space, 2, 7 respectively. If a command is
sent to the scanner to change any of these settings, the change will
NOT take effect until after serial program mode is exited.
EXAMPLE #2: The following example will set the scanner to the factory
default settings, Disable Scanning of Code 128 bar codes, change the
beeper tone, and add a “G” as a programmable prefix.

The scanner will emit a long beep!
The commands sent to the scanner do not include the small
superscripted ‘3’ that you see in front of each bar code string in the
MetroSelect manual. THE ‘3’ SHOULD NOT BE SENT, IT IS A
CODE TYPE DESIGNATION ONLY!
As you will note for commands requiring additional bar codes to be
scanned (such as prefixes, suffixes, timeouts, etc.), simply send the
code bytes in the same order that you would normally scan the bar
codes.
