※ 3 This output signal can be used by an external LED to indicate good read status.
The LED pin (PIN 10) produces a low output (default duration: 20ms, user-programmable) when a good read occurs. The
Good Read LED can be programmed On or Off. To learn how to program these parameters, please see the EM50S user
guide.
For the external LED circuit design, please see the "Good Read LED Circuit" section in this chapter. If the LED pin is not
used, leave it unconnected.
※ 4 Giving a 200μs low pulse on the nRESET pin (PIN 11) will reset the engine. Normally this pin should be asserted high
or in a high impedance state (there is a weak pull-up in the engine).
For the external reset circuit, please see the "Reset Circuit" section in this chapter. If the nRESET pin is not used, leave it
unconnected.
※ 5 This external trigger signal can be either level trigger or pulse trigger.
Level trigger: A trigger pull (i.e. driving the nTRIG pin low for over 20ms) activates a decode session. The decode session
continues until a barcode is decoded or the trigger is released.
Pulse trigger: When the trigger is pulled and released (pulse width : 50ms), scanning is activated until a barcode is
decoded or the decode session timeout expires.
For the external trigger circuit, please see the "Trigger Circuit" section in this chapter. If the nTRIG pin is not used, leave it
unconnected.
