(70-04014-37)

Revision A: March 1994

This version of the software enables the scan­ner to verify that the Motorola terminal is
ready before attempting a decode.

Baud Rate: 2400

Laser Enable Mode: Disable

Laser Enable Mode

The Laser Enable Mode parameter indicates
whether the LS 3020 must establish communi­cation with the Motorola terminal prior to at­tempting a decode. If this parameter is
enabled, the following sequence occurs when
the trigger is pulled:

• The scanner sends an ENQ (05H) to
the terminal.

• The decode LED flashes to indicate the
scanner is waiting for acknowledg­ment from the terminal. The LED
stops flashing when ACK (06H) or
NAK (15H) is received, or the trigger
is released.

• If an ACK is received, the unit at­tempts a decode.

• If a NAK is received, the unit issues
four short low beeps.
