CRVW3 3-Channel Vibrating-Wire Datalogger NOTE If you are using PakBus Encryption, the proper key should be entered in this screen. This key should match the value that was previously set in the CRVW3 using the PakBus tab in the Settings Editor tab of DevConfig. Refer to the online help system of DevConfig, PakBus Encryption Key field topic for more information. Also, if a Security Level 1, Security Level 2, or Security Level 3 code was set for the CRVW3 in DevConfig's PakBus tab, put the proper code in the Security Code box of this screen. Now switch to the Clock tab. The Check Clocks and Set Station Clock buttons should be active. If they are not, press the Apply button. Press the Check Clocks button to instruct LoggerNet to send a clock check command through the base station to the destination CRVW3 station. If the radio link is working, the current date and time should show up in the Adjusted Server Date/Time and Station Date/Time boxes within a few seconds. If LoggerNet returns an error after the clock check attempt, then something is wrong with the radio link or the configuration of LoggerNet and troubleshooting needs to occur. Investigate at both the radio level and at the LoggerNet level. In-field validation with a temporary laptop computer running LoggerNet helps to validate radio links while still in the field and reduces the need to return to the CRVW3 sites to investigate radio problems. See Section 13, Troubleshooting CRVW3 Networks, for additional troubleshooting procedures, or contact your local Campbell Scientific support representative. If the clock check was successful, and you want the station time to be synchronized with the LoggerNet computer station time, press Set Station Clock. If the clock check executed successfully, then the set clock operation should also work, otherwise troubleshooting may be needed. To add additional CRVW3 devices to your network map, you don't need to add a ComPort, IPPort or PakBusPort again. Simply click on the existing PakBusPort device and then Press the Add button. Choose CRVWSeries from 68

CRVW3 3-Channel Vibrating-Wire Datalogger

If you are using PakBus Encryption, the proper key should be

entered in this screen. This key should match the value that was

previously set in the CRVW3 using the

PakBus

tab in the

Settings

Editor

tab of

DevConfig

Refer to the online help system of

DevConfig

PakBus Encryption Key

field topic for more

information. Also, if a Security Level 1, Security Level 2, or

Security Level 3 code was set for the CRVW3 in

DevConfig’s

PakBus

tab, put the proper code in the

Security Code

box of this

screen.

Now switch to the

Clock

tab. The

Check Clocks

and

Set Station Clock

buttons should be active. If they are not, press the

Apply

button.

Press the

Check Clocks

button to instruct

LoggerNet

to send a clock check

command through the base station to the destination CRVW3 station. If the

radio link is working, the current date and time should show up in the

Adjusted

Server Date/Time

and

Station Date/Time

boxes within a few seconds.

LoggerNet

returns an error after the clock check attempt, then something is

wrong with the radio link or the configuration of

LoggerNet

and

troubleshooting needs to occur. Investigate at both the radio level and at the

LoggerNet

level. In-field validation with a temporary laptop computer running

LoggerNet

helps to validate radio links while still in the field and reduces the

need to return to the CRVW3 sites to investigate radio problems. See Section

13,

Troubleshooting CRVW3 Networks

, for additional troubleshooting

procedures, or contact your local Campbell Scientific support representative.

If the clock check was successful, and you want the station time to be

synchronized with the

LoggerNet

computer station time, press

Set Station

Clock

. If the clock check executed successfully, then the set clock operation

should also work, otherwise troubleshooting may be needed.

To add additional CRVW3 devices to your network map, you don’t need to add

ComPort

IPPort

PakBusPort

again. Simply click on the existing

PakBusPort

device and then Press the

Add

button. Choose
