4.1
– POST (Power On Self Test)
Each time power is applied to the StrataBox Sensor, it performs a series of self-tests to ensure that it is
working optimally. The tests occur as follows:
Test 1
– Initialization Test
Checks overall functionality of the sensor hardware to verify it is operational.
Test 2
– RAM Test
Verifies that the system RAM is operational.
Test 3
– Serial EPROM Test
Verifies that the Serial EPROM is operational and it’s checksum is valid.
Test 4
– Flash Memory Test
Verifies that the Flash Memory is working and it’s checksum is valid.
If Test 1, 2, or 3 fail, the Sensor’s green LED will blink rapidly at 4 Hz indicating an error. The
StrataBox Sensor will not be operational and the user should contact SYQWEST’s Support Dept. for
assistance. If the Sensor fails Test 4, the green LED will blink normally at 1 Hz, but will not function
until it is reprogrammed. The StrataBox PC Software will detect this problem and notify the user. (Refer
to
Troubleshooting
Section 4.4)
If the Sensor passes these tests, the green LED will blink at 1 Hz indicating that it’s working and waiting
for communication with the PC and StrataBox PC Software.
4.2 – LED Indicator
The StrataBox Sensor is equipped with a green LED which was designed to give the user immediate
information regarding the Sensor’s status. When power is supplied to the Sensor and it is working
properly, the LED will blink at 1 Hz indicating that the unit has powered up correctly and is waiting for
communication with the PC and StrataBox software. Once communication is established, the LED will
stay on continuously. However, if the unit is powered up and the green LED blinks at 4 Hz, then the unit
is problematic and will not be able to communicate with the PC until the problem is rectified. (See
Troubleshooting
Section 4.4)
4.3
– Firmware Update
The StrataBox Sensor is a self-contained unit and has it’s own set of Firmware. Periodically, SYQWEST
may offer Sensor Firmware upgrades which add new features and functionality. This section describes
the process involved in updating that firmware.
