7. Device pre-set and use mode.

a. Wireless Mode:

No setup operation is needed. Typically, the system is configured in factory, so the device is already associated to the system gateway. The

device is in STANDBY mode (

refer to Picture 7 - Command table

) for which is necessary to start it with the TEST command (

refer to 10 - Installation

procedure.

Otherwise, in case the device is in FACTORY RESET mode (

refer to Picture 7 - Command table

), that means it's ready for connecting to an existing

system, in order to associate it, make reference to the

“WineCap System - User Manual R30”

software manual. It is necessary to use the

WineCapManager

software on the PC connected to the gateway that will be linked with the device.

b. USB Logger Mode:

For this operation mode, stand-alone with data downloads through USB, the connection with the PC and the

WineCapManager

running on it

is necessary to modify the device 's operation mode. The sampling interval must be set with the device in STAND-ALONE

(refer to 11 - Stand-

alone USB datalogger installation.)

mode and automatically, the device 's clock is aligned with the PC's clock, in order to assure the temporal

reference of the sample.

Sampling operations start may be selected disconnecting the USB cable or giving the proper command with the magnetic key (

refer to 11 -

Stand-alone USB datalogger installation.

). More details on device 's connection/disconnection through the USB cable are available on the

WineCap

System - User Manual R30

manual.

c. On field transition from USB to Wireless datalogger:

This transition is practicable in field, during the sampling period, using the wireless network association command. When the association is

done, the datalogger becomes a wireless datalogger and, besides sending new measures to the gateway, starts a download process towards

the same gateway of the measures acquired during the stand-alone period (

refer to Picture 9 - Stand-alone device - Status table

8. Wireless device user interface.

The user interface consists of a “virtual” button that can be activated using the

WineCapKey

and of a two-colours led.

To give a command, user must approach the

WineCapKey

to the device’s sensible area and keep it in that position.; the following picture (

Picture 6

- WineCapKey positioning

) shows device’s sensible points.

The following COMMAND table describes the available commands:

WIRELESS MODE COMMAND table

Flash count

Description

1 flash

STATUS

Shows the device STATUS. As answer the led perform a flash sequence as reported in

the STATUS table. If the device is performing the TEST (

refer to TEST command

) this

command stops it.

2 flashes

TEST

Enter in TEST mode and transmits status and measurements every 5 seconds. If the

device is in STANDBY mode or it is out of radio range, this command forces the

connection procedure to the WSN and the return to the operative mode. The TEST

stops after 120 seconds. During TEST, the led continuously shows the STATUS to

monitor the received radio signal quality.

CAUTION: Measures acquired during TEST phase are NOT saved.

3 flashes

ENROLL

Association to the network: must be used when the device has not yet been included

in a network, starts the entry and association procedure to the gateway (

refer to

“WineCap System - User Manual R30”

4 flashes

+ 4 flashes

STANDBY

Temporary device deactivation: the device is stopped. The sampling process and the

radio are/is. turned off losing the connection to the network. To reactivate, a TEST

command is necessary. The STANDBY command must be given twice to confirm it: at

the first sequence the led flashes alternating RED and GREEN lights, waiting for the

second confirm sequence within 15 seconds. At the command execution the led

flashes as the STANDBY status (

refer to “Picture 8 - Status table - Radio signal quality”

5 flashes

+ 5 flashes

FACTORY RESET

The device performs the memory deleting procedure and goes in STOP status. All

samples, configuration and wireless network data associated are LOST. To reactivate

the device a new association and configuration procedure is necessary (

ENROLL

command

). Also in this case, the FACTORY RESET command must be given twice to

confirm it. At the command execution the led flashes as the “PROBE/DATALOGGER

NOT ASSOCIATED” status (

refer to “Picture 8 - Status table - Radio signal quality”

5 flashes

+ 3 flashes

LOGGER

NO WSN

As the previous command but performs only the WSN deleting procedure and

disassociate from the gateway. The device enters in LOGGER STAND ALONE mode:

data are kept, and the sampling activity CONTINUES with previous setup. Command

must be given with 2 sequences: 5 flashes and then 3 flashes. At the command

execution wait for the device reboot. At the STATUS command, “LOGGER” will be the

answer (

refer to “Picture 9 - Stand-alone device - Status table”

). A new association (

ENROLL

command

) is possible to a new gateway.

9. Device enrolment.

Not necessary if performed in factory before delivery.

Enrol the device to the network referring to the

“WineCap System - User Manual R30”

. In case the device is already enrolled but in STANDBY status, a

TEST command must be issued (refer to

Picture 7 - Command table

)

10. Installation procedure.

After installing the gateway in appropriate place in charge, (

refer to “WineCap System - User Manual R30

”), be sure that the device is enrolled to the

gateway and activated.

Head for the environment to be monitored. On the way, to check the quality of the radio coverage, use the "Field Measurer" function.

This function is activated issuing the TEST

(refer to Picture 7 - Command table)

command: position the

WineCapKey

in the spot indicated in

Picture 6 -

WineCapKey positioning

and wait for two AMBER flashes, then remove the

WineCapKey

from device. The "Field Measurer" function lasts enabled for

two minutes.

To issue commands to the device, place the

WineCapKey

where indicated.

Once the

WineCapKey

, is detected, the led periodically emits AMBER flashes with a 2 second cadence.

For each flash, a different command is associated; to confirm the command the

WineCapKey

must be removed from the sensible area immediately

after the number of flashes corresponding at the desired command. The TEST corresponds to the second pulse and activate the "Field Measurer"

function.

The device will give back the radio signal quality through led flashes:

Optimize reception selecting the best position: small movements can help.

If the signal is absent or insufficient at the install point, a

repeater WR12

should be put between (

refer to “WineCap System - User Manual R30

”). The

repeater

WR12

itself must be in a position where the signal level is at least sufficient.

The network will reconfigure itself automatically; the signal will be good again when the device synchronizes with the

repeater WR12

The link will not be reconfigured until completely lost by the device. Because of this, in some cases it could be necessary to force the operation.

In such cases, put the device in STANDBY mode, then run the TEST again (

refer to “WineCap System - User Manual R30

”).

NOTE: The display equipped datalogger

(WD04T)

is recommended, to verify the signal quality during devices installation.

11. Stand-alone USB datalogger installation.

Install the datalogger in appropriate place.

If the sampling process has not yet been activated, you can start it through the

WineCapKey

Bring it closer to the sensitive point, wait for 2 flashes (
