Introduction

Three types of wireless communication between scanner and cradle: synchronous, asynchronous and
batch modes.
Two types of wired communication between cradle and the Host: RS-232 and USB.

Wireless Communication

Wireless communication modes include Synchronous (default), Asynchronous and Batch modes.
 Synchronous Mode: If Zigbee is available, scanned data will be transferred to the cradle
immediately after a good read; if Zigbee is unavailable, the transmission of decoded data cannot be
accomplished.
 Asynchronous Mode: If Zigbee is available, scanned data will be transferred to the cradle
immediately after a good read; if Zigbee is unavailable, scanned data will be first stored in the flash
memory and be sent automatically to the cradle in a FIFO (first in first out) manner when Zigbee
becomes available.
 Batch Mode: Scanned data will be stored in the flash memory no matter whether Zigbee is available
or not. To send the stored data to the cradle, you need to insert the scanner in the cradle and then
press "P" button on the cradle.
