1. Description.
The WSD12-VW is a datalogger designed to measure 4 input channels to acquire frequency and temperature on vibrating wires, with storage
functionality of samples acquired.
2. Device pre-set and use mode.
a. Wireless Mode:
In this use mode, the datalogger records and transmits each measure sampled to the linked
gateway. Typically, the monitoring system is configured in factory, so, if the device is already
associated to the system gateway is in STANDBY mode ( refer to Picture 4 - Status table –
Wireless mode ). In this case, it is necessary to start it with the TEST command ( refer to Picture
3 –Wireless devices user interface ). After this operation, the datalogger reactivates, resumes
measure activity, and performs the connection to the gateway or to a repeater WR12.
Connection The onboard LED shows the radio signal quality for 2 minutes ( refer to Picture
4 - Status table –Wireless mode ).
Otherwise, in case the device is in FACTORY RESET mode ( refer to refer to Picture 4 - Status
table –Wireless mode ), that means it's ready for connecting to an existing system, in order
to associate it using the ENROL command, Refer 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, the dataloggers works in stand-alone, recording data in its internal
memory and without any wireless connection. This is not the factory setup so, to select it, the connection with the PC and the
WineCapManager running on it is necessary to modify the device 's operation mode. The device must be set in STAND-ALONE (refer to 6
- Stand-alone USB datalogger installation.) mode and the sample time must be configured; 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 6 -
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 5 - Status table - ).
3. 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 2 - WineCapKey positioning ) shows device’s sensible points.

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
ENROL
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 4 - Status table –Wireless mode” ).
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 ( ENROL 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 4 - Status table –Wireless mode” ).
5 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 5 - Status
table - Stand-alone mode” ). A new association ( ENROL command ) is
possible to a new gateway.

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 wireless communication 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.
6. 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 ( TEST ) (refer to Picture 3 –) and remove. The datalogger begins sampling according to
your settings through your PC.
Through the WineCapKey is possible to ask for the status, bring it close to the datalogger for 1 flash ( STATUS ) and remove it.
