※ I = Input; O = Output; od = Open Drain;
※ 1 The SW IN pin is used as trigger signal. A trigger pull (default duration: 10ms) activates a decode session. The decode
session continues until a barcode is decoded or you release the trigger.
For the external switching input circuit, please see the "Switching Input Circuit" section in Chapter 5.
For more details, please see the "Switching Input Signal" section in Chapter 9.
※ 2 The SW OUT pin is reserved as external switching output signal. If this pin is not used, leave it unconnected. It produces
high level (duration: 400ms) after a barcode is decoded.
For the external switching output circuit, please see the "Switching Output Circuit" section in Chapter 5.
For more details, please see the "Switching Output Signal" section in Chapter 9.
