Metrologic Instruments IS6520 Series, MS6520 Series

PROGRAMMING MODES (CONTINUED)

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.
