12. Status LEDs:
Power-up:
All LED's
OFF
.
Initialization:
After power is applied or reset switch pushed, LED 1 is ON for about 15 seconds, then
LED’s 2, 3, 4, 5, 6,
R1, R2, IN1, IN2, IN3, IN4, IN5, IN6, IN7 and IN8 are flashed once at the beginning
of initialization. LEDs 3 and 4 is turned ON for approximately 1 second after the hardware initialization
has completed, then the application code is initialized. The amount of time the application takes to
initialize depends on the size of the database, about 1 second without a card database. Each 10,000
cards will add about 2 seconds to the application initialization. When LED's 1, 2, 3 and 4 flash at the
same time, data is being read from or written to flash memory, do not cycle power when in this state.
If the sequence stops or repeats, perform the bulk erase procedure, see section 4
.
Running:
After initialization is complete, the LEDs have the following meanings:
LED
DESCRIPTION
1
Off-Line / On-Line and Battery Status
Off-Line = 20% ON, On-Line = 80% ON
Double Flash if Battery is Low
2
Host Communication Activity (Ethernet or Micro USB port)
3
Internal SIO Communication Activity
4
External SIO Communication Activity
5
Unassigned
R1
Reader 1:
Clock/Data or D1/D0 Mode: Flashes when Data is Received, Either Input
F/2F Mode: Flashes when Data/Acknowledgment is Received
RS-485 Mode: Flashes when Transmitting Data
R2
Reader 2:
Clock/Data or D1/D0 Mode: Flashes when Data is Received, Either Input
F/2F Mode: Flashes when Data/Acknowledgment is Received
RS-485 Mode = Flashes when Transmitting Data
D16
Flashes with Ethernet Traffic
YEL
Ethernet Speed: OFF = 10Mb/S, ON = 100Mb/S
GRN
OFF = No Link, ON = Good Link, Flashing = Ethernet Activity
IN1
Input IN1 Status: OFF = Inactive, ON = Active, Flash = Fault. See Note 3.
IN2
Input IN2 Status: OFF = Inactive, ON = Active, Flash = Fault. See Note 3.
IN3
Input IN3 Status: OFF = Inactive, ON = Active, Flash = Fault. See Note 3.
IN4
Input IN4 Status: OFF = Inactive, ON = Active, Flash = Fault. See Note 3.
IN5
Input IN5 Status: OFF = Inactive, ON = Active, Flash = Fault. See Note 3.
IN6
Input IN6 Status: OFF = Inactive, ON = Active, Flash = Fault. See Note 3.
IN7
Input IN7 Status: OFF = Inactive, ON = Active, Flash = Fault. See Note 3.
IN8
Input IN8 Status: OFF = Inactive, ON = Active, Flash = Fault. See Note 3.
K1
Relay K1: ON = Energized
K2
Relay K2: ON = Energized
K3
Relay K3: ON = Energized
K4
Relay K4: ON = Energized
Note
: If this input is defined, every three seconds the LED is pulsed to its opposite state for 0.1
seconds, otherwise, the LED is off.
