Campbell CR300 series Getting Started Manual page 5

datalogger ships with a program set to run on power-up, the Power LED flashes 3 times
every 10 seconds when powered over USB. When powered with a 12 V battery, it flashes
1 time every 10 seconds.
7. From the COM Port list, select the COM port used for your datalogger.
8. USB and RS-232 connections do not typically require a COM Port Communication Delay -
this allows time for the hardware devices to "wake up" and negotiate a communications
link. Accept the default value of 00 seconds and click Next.
9. The baud rate and PakBus address must match the hardware settings for your datalogger.
The default PakBus address is 1. A USB connection does not require a baud rate selection.
RS-232 connections default to 115200 baud.
NOTE:
Unlike the RS-232 port on some other Campbell Scientific dataloggers that autobaud,
the CR300 RS-232 port does not. If the hardware and software settings for baud rate
and PakBus address do not match, you will not be able to connect.
10. Set an Extra Response Time if you have a difficult or marginal connection and you want
the datalogger support software to wait a certain amount of time before returning a com-
munication failure error.
11. LoggerNet and PC400 users can set a Max Time On-Line to limit the amount of time the
datalogger remains connected. When the datalogger is contacted, communication with it
is terminated when this time limit is exceeded. A value of 0 in this field indicates that there
is no time limit for maintaining a connection to the datalogger.
12. Click Next.
13. By default, the datalogger does not use a security code or a PakBus encryption key. There-
fore, the Security Code can be set to 0 and the PakBus Encryption Key can be left blank. If
either setting has been changed, enter the new code or key.
14. Click Next.
15. Review the Communication Setup Summary. If you need to make changes, click Previous to
return to a previous window and change the settings.
Setup is now complete, and the EZSetup Wizard allows to you click Finish or click Next to test
communications, set the datalogger clock, and send a program to the datalogger. See
communications and completing EZ Setup (p. 4) for more information.
