Initialisation Device

Instructions for Use

6. Operation

Operation of the Initialisation Device shall be carried out by trained personnel familiar with

the STRYDE system.

During deployment, the Initialisation Device is used to activate the sensor and provide it with

all necessary parameters from the hand-held terminal before planting it in the ground. The

Initialisation Device is flashing blue and green when it is connected to the hand-held terminal

and synchronized to GNSS. The operator shall ensure the terminal is connected to the correct

Initialisation Device and that it is set to Initialize mode. The hand-held device will give an

audio signal to confirm successful initialization. If the Initialisation Device does not have a

flashing blue light, the sensor was successfully initialized with all parameters, but the

synchronization to GNSS has failed. The hand-held device will also indicate this with an on-

screen error message.

The sensors are left in the ground for days to weeks, acquiring seismic data. Upon retrieval,

the operator ensures the Initialisation Device is connected to the hand-held terminal via

Bluetooth and set to Retrieve mode. Then it is used to deactivate the sensor, and at the same

time providing the last synchronisation event. This is acknowledged by the hand-held terminal

using a different audio signal than for deployment.

At the end of each shift, the Initialisation Device is transported back to the hub where it is

cleaned, charged and new parameters are downloaded. Having completed these process

steps, the unit is ready for another day in the field.

Various LED sequences are used to distinguish the Initialisation Device state. In general, all the

states described above can be verified by reading the Initialisation Device Status from an

MPTS.

Initial start-up: Short Blue-Green-Red sequence followed by Long Blue-Green-Red sequence

Active mode: Short green flashes

Low-power mode: Short red flashes

GNSS lock: Short blue flashes

In charger, charging: Red LED on/off

In charger, full: Green LED on

SW download over Bluetooth: Green LED on/off

Loading GNSS almanac data internally: Blue LED on/off, flashing turquoise three times

when completed

The Initialisation Device shall be inspected for damage when returned from the field. Units

with broken housing shall be clearly marked on the top cap so they are easily identified when

placed with other devices. To avoid water ingress in the cleaning process, such damaged units

shall be decommissioned when returned to the hub.

The Initialisation Device shall only be charged in chargers specifically designed for the

STRYDE system. Charging shall be done away from flammable materials, and a fire

extinguisher shall be within reach for emergency use.
