IRING
To connect an IPI system to a CR310 Campbell logger, an RS485 to RS232
i
nterface, such as RST’s ELGL4000 series, will need to be used. The interface/IPI
assembly can be wired as follows (Figure 5-8):

In the event that the C1 and C2 ports are vacant, the C1 and C2 ports can be used
in place of the DB9 port. See the wiring diagram outlined in Figure 5-9.

Updating the Modbus Addresses With a CR310
Before updating the Modbus addresses on the IPI string, ensure that all settings
have been saved on the logger unit.
Modbus addresses for sensors connected to a Campbell CR310 logger can be
updated via a CRBasic code. Once the user has defined the number of sensors
and their respective serial numbers, the code will automatically assign a Modbus
address to each sensor in the string once the code is run.
1. Open LoggerNet.
2.
Navigate to the “CRBasic Editor” option under the
Program
menu (Figure 5-2).
