MP9320 V2.8 Power Up and Initialization
When the power supply is connected, the reader starts an internal initialization sequence.
This sequence momentarily lights the LEDs as follows:
1.
Transmit and Sense on momentarily, then off
2.
Sense flashes
3.
Power flashes
4.
Fault flashes
5. All four flash
6.
Transmit and Power flash
7. Beeper on
If the
Fault LED illuminates during the intialization sequence, the reader has detected a
software load fault. Restart the reader to clear the fault.
Figure 12–LED Startup Sequence
The reader is operational when the Power LED remains on.
After the startup sequence, the RF multiplexer in the MP9320 V2.8, alternately provides
RF power to each of the four antennas. The
Active Antenna LEDs indicate which antenna
is transmitting.
