Communication Mode; Cd200 Data Line Interface Definitions - Newland NLS-NVH200 User Manual

Communication Mode
Communication modes include synchronous mode (factory default), asynchronous mode and batch mode.

Synchronization mode: with Bluetooth network, the scanner will be transmitted to the base immediately
after successful decoding. Without network, transmission will be failed.

Asynchronous mode: in the case of Bluetooth network, the scanner will be transmitted to the base
immediately after the decoder is successfully decoded. In the network‐free state, the scanner saves the bar
code to the user's FLASH memory in accordance with FIFO (first in first out), and automatically transmits the
bar code to the base after recovering the network.

Batch mode: Without considering the existence of Bluetooth network, the scanner automatically saves the
bar code to the user FLASH after decoding successfully, places the wireless gun on the base, and presses the
"P" key on the base (see Figure 1‐2) to realize the batch transmission.
