3.8 Forced Initialization

If the scan engine is unresponsive, you can force the scan engine to initialize.
Note: When initialization is forced, data read by the scan engine is not sent to the host device.
Force the Scan Engine to Initialize
1. Turn off the scan engine.
2. While keeping TRIGn Low, turn on the power.
3. With TRIGn low, wait for at least 10 seconds. TRIGn becomes active and the scan
engine can read barcodes.

4 Interface

The scan engine supports these serial interfaces:
•

UART

•
USB-COM
•
USB-HID
4.1 UART
UART is one of the most commonly used serial interface protocols. When using the UART
interface, make sure the 12-pin FFC cable is connected to UART signals.
Caution: UART is a standard factory default setting. If the host is using a USB connection
circuit, communication will fail.
