SPEEDBOXR41NoiseEmissionsTestSystem / StatusLEDMeaning

Status LED Meanings

Time pulse (yellow)

Flashes at 1Hz 50% duty cycle when the GPS receiver has a lock, the falling edge of the output is precisely synchronised with the second boundaries of GPS time. I.E. the LED is lit for the second half of each second.

Trigger (blue)

When the trigger LED is on the triggered output is active.

SBAS (yellow)

Indicates the SBAS correction status of the GPS solution. Not currently implemented.

Error (red)

Flashes to indicate different error conditions. The error conditions corresponding to the number of flashes are given in the table below. More than one error can be present at one time, for example a series of 3 flashes followed by 4 flashes would signify both error conditions 3 and 4 are present.

Error Code

(Number of Flashes)

Error Condition
1 GPS module 1 failure
2 GPS module 2 failure
3 GPS antenna 1 short circuit
4 GPS antenna 2 short circuit
6 Not used in this hardware
7 External IMU not detected (SPEEDBOX-INS only)
8 External IMU calibration checksum fail (SPEEDBOX-INS only)
9 RS232 input buffer overflow
10 The hardware does not support the currently installed firmware version


Power (red)

On when power is applied to the unit. It then briefly flashes off at 1Hz whilst the firmware is running. If it remains continuously on then power is applied but the firmware is not running.

GPS Status 1 (green)

Continuously on when GPS receiver 1 has a lock.

GPS Status 2 (green)

Continuously on when GPS receiver 2 has a lock (RTK and dual-antenna INS versions only).

Modem

Two status indication LEDs:

OPR (Red): Indicates power on status

LNK (Green): Indicates that a wireless link is established. Flashes when in configuration mode

RST: Press reset button twice to entre configuration mode. See modem manual for further instructions.

Laser trigger

Green: indicates power is enabled Orange: Light on indicates no target detected. Light off indicates target detected


DASH4PRO

The LEDís on the DASH4PRO are configurable. The default configuration is set to have no LEDís at 50Km/h.
