Chapter 9 Communication
9.1 Bluetooth
Interface
The QR-coded parameter menu and the configuration software (ScannerSetting_2D) provide a choice of various
communications conditions. Under the communications conditions you choose, code data read can be transferred to
the external equipment or computer.
(1) Communications protocol
You can select either non-acknowledge mode or ACK/NAK mode.
Non-acknowledge mode (default)
The scanner transfers code data read, regardless of the CTS signal level.
ACK/NAK mode
The scanner transfers code data read, regardless of the CTS signal level. After that, however, it waits for the response
from the host and processes it. The configuration software (ScannerSetting_2D) only provides ACK/NAK timeout
settings from 100 ms to 9.9 s in 100 ms increments.
ACK: Normal end
NAK: Retransfer
(2) Timeout period for slave to wait for a connection request
The scanner, as a slave, waits for a connection request from the master for the specified timeout period--2 (default), 4,
10, or 30 minutes.
If the scanner cannot receive a connection request from the master within the specified timeout period, it switches to
standby, the same status as the Bluetooth
wireless link has been broken.
(3) Automatic disconnection of Bluetooth
wireless link
If the Bluetooth
interface is not used for the specified timeout period, the scanner automatically breaks the
Bluetooth
wireless link.
You can select the timeout period within the range from 5 to 640 minutes in 5-minute increments and also disable the
automatic disconnection, using the configuration software (ScannerSetting_2D).
