Chapter 5
Programming Via Escape Sequences
5–9
Reset tests and verifies the contents of EEPROM, initiates the ROM/RAM
self tests, and configures the decoder according to the contents of EEPROM.
Note: When using a hand–held laser scanner or Catalog No. 2755–L2 scan
head, do not trigger either device during power up. If you hold the trigger,
the decoder will act as if a wand is connected. The decoder will not
recognize any laser scanners until it is reset by an escape sequence, or by
turning the decoder OFF and then ON.

Store Configuration In EEPROM

Reset Examples
To reset the decoder, send either of the following escape sequences:
Esc – y 1 Z
Esc E
Note: Esc E can also be used to reset the decoder. Make certain that you do
not use this escape sequence as part of your application program.
The configuration that is stored and recalled from the nonvolatile memory
(EEPROM) is controlled with an escape sequence.
Important: Whenever the decoder is configured using the bar code menus,
new configurations are automatically stored in the EEPROM. Configuration
via escape sequences is different. Once an escape sequence is received, the
new configuration takes effect, but is not stored. To store the configuration
in EEPROM, the Store Configuration escape sequence must be sent.
