LED output: When using this signal, a driver circuit is needed to drive an external
LED.

TRIG
I
Trigger signal input: Driving this pin low for 50ms causes the engine to start a scan
and decode session.
※
1 Beeper output statuses.
a. Power on beep: When powered on, PWM signal output will occur 200ms later and last for 350ms. The frequency is
1.67~2.5khz Khz.The duration is regular. The beep can be programmed On or Off. For more details, please see the
EM3080-W user guide.
b. Good read beep: PWM output will occur after successful decode. The default duration and the frequency are
respectively 80ms and 2.46Khz. These parameters can be programmed. For more details, please see the EM3080-W user
guide.
c. For beeper driver circuit, please see
Beeper
in Chapter 4.
d. If this pin is not used, leave it unconnected.

2 Good read LED
a. The low level output will occur after successful decode. The default duration is 220ms. The length of time can be
programmed. For more details, please see the EM3080-W user guide.
b. For LED driver circuit, please see
Good Read LED
in Chapter 4.
c. If this pin is not used, leave it unconnected.
※
3 There are two kinds of trigger signal input statuses.
a. Level trigger: A trigger pull keeps level low to activate a decode session until a barcode is decoded.
b. Pulse trigger: When a trigger is pulled and released, scanning is activated until a barcode is decoded or the decode
session timeout expires.
c. For trigger driver circuit, please see
Trigger
in Chapter 4.
