Using an External Trigger
Appendix G — Using an External Trigger
Two types of inputs are used on Microscan readers. 5 volt devices have NPN trigger
inputs. 10-28 volt devices have optoisolated inputs and outputs.
5 Volt Devices
To trigger a 5 volt device, the input has to be pulled down to “signal ground” (NPN). This
can be done by relays or by a transistor-sourced signal. If a 5 volt device is used in combination
with an IC-332, it must be connected as a 10-28 volt device.
10-28 Volt Devices
To trigger a 10-28 volt device, a small amount of current needs to flow from “Trigger +” to
“Trigger –”. If a PNP source is used, “Trigger –” must be connected to “signal ground”. If an
NPN source is used, “Trigger +” must be connected to the supply voltage.
