FIGURE 2-1. System Description
3. Software and Datalogger Compatibility
PC208 Software Index #5348-00 or higher is required for use with MD9s.
Customers using older software may purchase a software update for a nominal
charge by contacting Campbell Scientific.
The following dataloggers may be used in an MD9 network.
CR10
all
21X
SN6195 or higher
700X
Control Module SN1670 or higher
21Xs and 700Xs with lower SNs require a resistor modification which permits
the respective 5 Volt power supplies to source enough current to operate an
MD9. Contact Campbell Scientific customer service if your datalogger
requires this modification.
4. ID and Baud Rate Selection
Each MD9 in an MD9 network must have a unique ID. The ID is set by the ID
select switch (Figure 4-1). This switch is located under the cover, and can be
accessed by removal of the four cover screws.
Appendix C gives a complete list of ID and switch settings.
