Upon power up, LED1 lights to signify that the OEM 200 is receiving power. Immediately following, the OEM 200 flashes both
LED2 and LED3 for 1 second, then flashes LED2 for 0.5 seconds, then flashes both LED2 and LED3 for 1 second, then turns
LED2 solid on to indicate the OEM 200 is ready for operation.
During normal operation the LEDs behave as described in the table below

General Output
The General Output is used to notify the host system of OEM 200 activity. A typical use for the General Output is to enable
audio or visual user feedback to inform the user of OEM 200 activity. The General Output can be connected directly to a
digital input on the host device or connected to an LED and/or buzzer. It is recommended to provide power to an LED or
buzzer with a separate power source.
At power on start up the General Output sends out a single pulse for 200 ms.
Aer a Power-On-Self-Test (POST) the General Output sends out a pulse simultaneously with each short and long LED
flash described in the table above.
During normal operation the General Output sends out a single 150 ms pulse when a card is read successfully.
