16 - D2O VCP Product Manual
6.1 INTRODUCTION
Before commencing any programming or commissioning tasks the following
prerequisite tasks must be completed:
• A
4-Pin M12 to USB-A Cable
must be connected between the D2O and
a USB port of the Computer, without extension. Ensure the USB Port is
capable of providing at least a 500mA supply
• It is recommended that the Power Switch of the D2O unit is set to the ON
position
• Ensure GPS satellite signals are available by moving outdoors or close to a
window (required to obtain date, time and location settings of the D2O)
• Serial Terminal software is installed on the Computer
6.2 PRE-PROGRAMMING CHECKLIST
6.3 START-UP SEQUENCE
Before the D2O can perform its normal operation it must be programmed with
the desired operating parameters.
Programming occurs via a serial interface, using a plaintext protocol that can
be entered by either human or automated system input. A Serial Terminal
software application (such as Tera Term ), running on a Computer, is required
in order to send human entered input commands via a Command Line
Interface (CLI) to the D2O.
Once a connection is established, the CLI provides the following setup
features:
• Set device acquisition and system parameters
• Generate a Commissioning Report to confirm current settings
When setting up a D2O for the first time the steps shown in the following
sections should be sequentially followed to ensure the D2O will be correctly
setup and perform its normal operation.
Once powered the expected start-up sequence for the D2O is as follows:
• The unit will power up and within 2-5 seconds a light within the Battery
Switch should flash a green light twice
• The D2O now acquires the GPS location, time and date settings which can
take up to 90 seconds
• Next the start-up sampling configuration and system status information is
prepared for transmission at the next opportunity, before the unit enters
sleep mode
• Without further intervention the D2O will then wake at the next set sampling
time
• The unit is now ready to interface via the Serial Terminal software
